What policy options does the Japanese public prefer, and what might shift its attitudes? These are some questions the Stanford Japan Barometer (SJB) sets out to answer. SJB is a large-scale public opinion survey on political, economic, and social issues in Japan. Co-developed and led by Stanford sociologist Kiyoteru Tsutsui, the deputy director of APARC and director of the Center’s Japan Program, and Dartmouth College political scientist Charles Crabtree, a former visiting assistant professor with the Japan Program, SJB has so far published the results from its first two waves.

Wave 1 focused on issues related to gender and sexuality in Japanese politics, while Wave 2 focused on issues related to foreign policy and national defense. SJB findings fielded in these two waves indicate that most Japanese support recognizing same-sex unions, legalizing a dual-surname option for married couples, promoting women’s leadership in society, and that, in a Taiwan contingency, ​​Japanese people would be hesitant to fight China but would respond to a request from the U.S. military for logistical support.

Jointly with the Japan Program, GLOBE+, an international news outlet operated by the esteemed Japanese newspaper Asahi Shimbun, is publishing a series highlighting SJB findings. You can read an English translation of the first three pieces in this series. Here, we provide an English translation of the latest installment in the series, published on September 19, 2024. The translation was initially generated via DeepL. The text below was edited for accuracy and style.

Japanese Public Opinion on Legalizing Same-Sex Unions

Japan remains the only G7 country that has not legalized same-sex marriage or introduced a partnership system that offers marriage-equivalent rights at the national level. It is also the only country worldwide that mandates married couples to adopt the same surname.

Yet, according to the SJB survey, 47.2% of respondents were either "very much in favor" (18.6%) or "somewhat in favor" (28.6%) of legalizing same-sex marriage in Japan. In contrast, 15.8% were either "very much against" (6.8%) or "somewhat against" (9.0%), while 36.9% held a neutral stance, being “neither in favor nor against.” Support for same-sex marriage outpaced neutral responses by nearly three times.

The survey also explored public support for same-sex couples in leadership roles by asking respondents what kind of individuals they would like to see as members of the Diet or as outside directors of companies.

Participants were asked to consider six key attributes when identifying the types of candidates they would prefer to see in the next House of Representatives elections:

• Age (from 32 years old to 82 years old, in 10-year increments)　
• Gender　
• Marriage (married, never married, divorced, same-sex couple)　
• Number of children　
• Educational background　
• Work experience (11 types, including finance, economy, industry, and foreign affairs bureaucrats, business owners and executives, governors, local legislators, and homemakers)

Respondents were asked to create two “candidate images” by randomly combining six attributes and selecting one in a two-choice format. The same question was repeated a total of 10 times with different choices. The responses obtained from all survey participants were tabulated and analyzed.

The reason for the complexity of the method is that, from a statistical point of view, it allows the researchers to get closer to the “true feelings” (public opinion) of the respondents.

For each of the attributes, the percentage would be 50% if the respondents were indifferent to sexual orientation, but 45% of the respondents were in favor of electing a person from a same-sex couple to the National Assembly and 43.5% were in favor of electing a person from a same-sex couple to be a non-executive director, showing a downward trend in support. Although many people are in favor of same-sex marriage, it is evident that there is still a sense of discrimination against sexual minorities holding important public positions.

Of note, male respondents were less supportive of electing a person from a same-sex couple to the National Assembly, at 37.6%, compared to 50.6% of women. Support for electing a person from a same-sex couple to the National Assembly was also lower among respondents aged 70 and older at 31.1%, and higher among younger respondents: 58.9% of those aged 18 and 19, 60.5% of those aged 20 to 24, and 56.5% of those aged 25 to 29.

To identify what conditions could move public opinion, the researchers designed seven prompts regarding same-sex marriage, assigned them randomly to respondents, and compared their answers. The prompts included assumptions such as “In Japanese society, marriage is traditionally between two people of the opposite sex;” “If same-sex marriage is recognized, it will make it easier for same-sex couples to raise children, which may lead to an improvement in the declining birth rate and have beneficial effects for Japanese society;” and “From the perspective of human rights and gender equality, it would be unfair not to recognize same-sex marriage.”

The results show that support for same-sex marriage increases the most when respondents are presented with an argument that not allowing same-sex marriage is unfair from the point of view of human rights and gender equality.
 

Public Opinion on Legalizing Dual-Surname Option for Married Couples

The SJB survey also examined the public opinion of the selective surname system, which would allow married Japanese people to keep their premarital surnames if they wished. In surveying this issue, the researchers used two different question formats to shed light on a debate surrounding the Japanese government’s modification of its public opinion survey on this issue between 2017 and 2021. After the government revised the question asked on this matter, support for the selective surname system dropped from a record high of 42.5% in 2017 to a record low of only 28.9% in 2021. Therefore, the SJB randomly assigned respondents to answer two versions of the government survey under scrutiny, from 2017 and 2021.

In the 2021 government survey, respondents had to read certain materials before saying whether they approve or disapprove of the selective surname system. The materials included two tables. One, titled “Reference Material on Married Couples’ Surnames and Family Names,” explains the current system of married couples' surnames, the selective system of married couples' surnames, and the legal system for the use of the common name of the maiden name, respectively.

The other table explains the options, with the horizontal axis divided into “maintain the system of married couples with the same surname” and “introduce a selective system of married couples with separate surnames,” and the vertical axis divided into “no” and “yes” for “need to establish a legal system for using the maiden name as the common name.”

In 2021, the respondents were asked to choose from the following three options: “It is preferable to maintain the current system of married couples having the same family name;” “It is preferable to maintain the current system of married couples having the same family name and establish a legal system for the use of the maiden name;” and “It is preferable to introduce a selective system of married couples having separate family names.”

On the other hand, the question until 2017 was “Currently, married couples must always take the same surname.” After explaining the current system and the system of selective married couples' surnames, the question was “As long as a couple is married, they should always take the same surname.. If a couple wishes to take their premarital surname, they may change the law to allow each person to take their pre-marital surname. The couple should take the same surname, but it is acceptable to change the law so that a person who has changed his/her surname by marriage can use his/her pre-marital surname as a common name anywhere.”

As a result, under the 2021 method, 30% of the respondents chose “it is better to maintain the current system of the same family name for married couples,” 39% chose “it is better to maintain the current system of the same family name for married couples and establish a legal system for the use of the maiden name as a common name,” and 30% chose “it is better to introduce an optional system of separate family names for married couples.

On the other hand, in the 2017 method, 23% of respondents said “As long as a couple is married, they should always take the same surname (family name), and there is no need to change the current law,” while 57% said “If a couple wishes to take their pre-marital surname (family name), it is fine to change the law to allow each couple to take their pre-marital surname (family name). 57% said they “do not mind” and 19% said they “do not mind” if the law is changed to allow married couples to use their maiden name as a common name even if they wish to keep their maiden name. In other words, 57% of the respondents chose to selectively separate their surnames.

The 2021 method was criticized for how the question was asked, which was different from how it had been asked until 2017 and allegedly induced more support for using common names. The results of the SJB survey show that even if respondents were randomly assigned to the 2017 and 2021 methods at the same time, the results of the 2021 method would show more support for using common names. In other words, one should be wary of citing the results of the 2021 method to argue that support for the use of common names is higher than support for a legal change to selective married couples.

To find out under what conditions public opinion would move toward selective surnames for married couples, the SJB also conducted an experiment on different arguments that might influence support for a legal change to allow married couples to keep different surnames.

The arguments included different prompts: “In Japanese society, there is a tradition that married couples take the same surname once they get married;” “In Japanese society, there is a tradition that married couples take separate surnames once they get married;” “Among those who had surnames in pre-modern Japan, and even in early Meiji Era Japan, it was normal for married couples to have separate surnames after marriage;” “It is largely women who change their surnames after marriage;” “If married couples take different surnames after marriage, it will weaken family ties and have negative impact on children, which will lead to a loss for Japanese society.” The respondents were asked whether they agreed or disagreed with the prompts.

The results show that the argument about social costs — how allowing married couples to maintain different surnames would weaken family ties with harmful effects on children — seems to substantially change public attitudes, reducing support for a legal change.

The SJB survey results suggest that responses to polls vary depending on how the questions are asked and on the assumptions made. When looking at poll results, it is therefore important to note the framing of the questions and prompts.

On May 24, 2024, Satoshi Yamaguchi, drummer (RADWIMPS) and Visiting Researcher at Keio University, gave an inspiring talk to alumni and students of all of SPICE’s 2023–2024 courses in China, Japan, and the United States. This was the first time that a special online session was held for all of SPICE’s courses. Rylan Sekiguchi facilitated the session, and Dr. Makiko Hirata served as an interpreter.

Drummer Satoshi Yamaguchi joined the rock band RADWIMPS as a freshman in college. When he was 20 years old, the band made its major label debut and quickly grew in popularity, earning multiple #1 hits, awards, and recognitions. According to Satoshi, “Everything was smooth sailing.” However, in 2009 Satoshi began to suffer from musicians’ dystonia, a condition that made it increasingly difficult for him to play the drums. According to Satoshi, “in 2015, in the middle of creating music for the megahit anime movie Your Name that would catapult RADWIMPS to worldwide fame, I made the difficult decision to leave the band on an indefinite hiatus. It was an extremely emotional and painful time for me.” Today Satoshi is a small business owner in a town called Hayama in Kanagawa Prefecture, Japan—growing rice and running an ice cream factory—and is also a Visiting Researcher at Keio University, where he conducts research on musicians’ dystonia with Dr. Shinya Fujii, Director of Neuromusiclab at Keio University Shonan Fujisawa Campus. He is also collaborating with Dr. Takako Fujioka, Professor of Music at Stanford University, who is a neuroscientist investigating brain functions related to music. Together they work on a research project that focuses on physical and psychological health issues in drummers in the United States. Satoshi hopes to understand his condition better and eventually return to the stage.

In the special online session, Satoshi shared his unique life experiences—both successes and setbacks—and how they have shaped his attitude and perspectives on life. In his opening comments, he noted, “I would be very happy if I could share with you some insights that I have gained through my experiences and words that have supported me during difficult times, and if they could provide some hints for your future life.” As students and alumni of SPICE’s courses reflected upon his talk, multiple insights that he shared especially stood out and are important lessons for youth. These insights are shared below through eight excerpts from his talk.

First, while reflecting on his youth, Satoshi noted,

Not long before I joined RADWIMPS, when I was in high school, I formed a metal rock band with my music-loving friends in my hometown of Yokohama and played the drums. I was so busy with my band and part-time job that I didn’t study much, especially English, which I was very bad at. It is hard to believe that I am speaking in English in front of you today.

Satoshi’s presentation in English to the biggest audience of students SPICE has ever convened was an inspiration for students who are studying English in Japan and China, and English language learners in the United States.

Second, while reflecting upon a band competition as a high school student, he noted,

… our [metal rock] band’s goal was to participate in a national high school music festival held once a year at Yokohama Arena! How fascinating to have the chance to perform on a stage big enough to hold 10,000 people, isn’t it? Of course, the auditions were tough, and we were unsuccessful in our first and second years, but in our third year, we finally made it to the finals. On the day of the show, we were full of confidence. After successfully completing our performance as the first band, we listened to our rivals, saying “None of the other bands were that good.” However, when I heard the last band’s song, I was shocked beyond belief. It was RADWIMPS. Some of the lyrics of one of their songs made me think that someone else seemed to know my heart better than I. RADWIMPS won the competition, my band lost.

Satoshi ended this segment of his talk by noting that “Perhaps the day will come when your biggest rival today will become your best friend.” This statement really seemed to have resonated in students, as they all knew that Satoshi eventually joined RADWIMPS.

Third, Satoshi reflected upon a life-long lesson that he learned from one of his fellow RADWIMPS band members. Satoshi recalled,

Toward the end of my first year of college, my [metal rock] band broke up and RADWIMPS was looking for a new drummer, which led to me joining. We were creating new songs, but at the time I could only hit a simple 8-note beat, which is often played in rock music. One day, Yojiro, the songwriter, said to me, “Satoshi, you are not allowed to play an 8-note beat without a reason.” When I was confused, he said, “We are going to make music that has never been made before. We are aiming for a future where a genre called RADWIMPS will be born, just like rock, pop, and jazz. To do that, you can’t just play the beats that have been around before, can you? You have to pursue your own new beat.” At another time, he said, “Your children and grandchildren will one day listen to the beats you play. Are you sure that’s the best beat?” It is embarrassing to look back now, but at the time I did not have his kind of vision at all.

Throughout his talk, Satoshi underscored the importance of creativity. I believe that his statement, “You have to pursue your own new beat,” has remained in the minds of many students. Another insight that he shared was that “Out of limitations come innovations. Being forbidden to play the 8-note beat, which I was most familiar with, allowed me to use my imagination, which had been dormant inside me, to ask, ‘What can I do then?’” One beat that was created at that time became the basis for the theme song of Your Name.

Fourth, while Satoshi openly shared his experience with musicians’ dystonia, I witnessed the very serious looks on the faces of the students and alumni. He reflected,

… when I was 24 years old, my right foot suddenly stopped moving while playing the drums. This was a symptom called musicians’ dystonia, as I later found out. The bass drum, played with the right foot, is the foundation of music. The dystonia made it impossible for me to express myself musically as I had imagined. For the next six years, I continued to perform, trying to do the best I could. However, the symptoms gradually became worse, eventually spreading to my left foot, and I no longer found pleasure in playing music. Then in 2015, I made the decision to give up being the drummer of my favorite band in the world and take an indefinite hiatus. It was one of the heaviest and most painful moments of my life.

I am confident that Satoshi’s reflections prompted many students to think about the “heaviest and most painful moments” in their lives and ask themselves, “What can we learn from these moments, and how can we use these lessons as we go through our lives?”

Fifth, Satoshi reflected upon the continued success of RADWIMPS and noted,

When I was exhausted both mentally and physically, I came across this town, Hayama…[with a view of] Mt. Fuji over the sea. When I saw this scenery, for the first time in a long time, I felt a sincere emotion. I loved the state of mind I was in when I was looking at this mountain. I felt that this town was calling me. Trusting this intuition, I decided to move to Hayama with my family. Shortly after I started living in Hayama, I encountered these rice terraces… as I deepened my relationships with local farmers, I learned that rice terraces were facing a number of difficulties and their survival was at risk. I began to wonder if I could do something about this place that had saved my life.

Hayama’s rice terraces are visited by Silicon Valley Keio International Program (SKIP), an international exchange program between Keio and Stanford students. Through such programs, Satoshi is giving back to his community by “respecting tradition while innovating it,” and Satoshi hopes that all students will consider this as well for communities that have made a difference in their lives.

Sixth, 20 years later, RADWIMPS has become one of Japan’s leading bands, and Satoshi commented that “my three sons sing our songs every day! I am now once again feeling the amazing power of having a vision.” Satoshi urged the audience to “imagine what the future looks like, and then truly believe that it can be realized,” which is such a powerful message for youth. Also, about half a year into his farming life, the film Your Name was released in September 2016. Satoshi was impressed with the film but felt that,

… the whole world was telling me, “You made the wrong choice.” And I couldn’t even listen to the past songs of RADWIMPS anymore. I was also disappointed in myself for not being able to honestly be happy about the success of a band without me. But it was also music that saved me from such feelings…. If success is all there is to life, then it might mean that I, who could not share in the worldwide success of Your Name, would be unhappy for the rest of my life. But is that really true? There might be other ways to find happiness. That’s how I came to think of it.

Following this reflection, Satoshi decided to seek his “own kind of honest enjoyment” and encourages students to seek theirs as well.

Seventh, during a recent research visit to Stanford University, he was introduced to Stanford Taiko through a student whom he met through SKIP, and also met Roy and PJ Hirabayashi, founding directors of San Jose Taiko. Sekiguchi, who moderated the seminar by Satoshi, used to be a performer with both Stanford Taiko and San Jose Taiko. Reflecting on a San Jose Taiko performance, Satoshi stated,

I have seen many shows in my life, but this was the first time I had ever seen an encore that not only involved all of the performers but the audience as well dancing in a circle. It made me rethink the essence of what music is. And as I played with people who truly love taiko and music, I gradually remembered the joy of playing instruments. After all, I want to play drums again… [While observing taiko and talking with PJ, Satoshi realized that] It is ‘using the voice to make the real bass drum sound.’ It happened while I was learning a new beat for taiko. In the taiko community, there is no musical score, and rhythmic patterns are taught orally.

He commented to students that “singing and the voice are the most fundamental instruments that humans have,” and that “other instruments are an extension of them.” He is currently working on the research and development of a new instrument using the voice. He believes that he will find his own “new sound” and the day will come when he will once again stand on stage as the drummer of RADWIMPS.

Eighth, Satoshi concluded his talk with two reflections on his life. The first was “Difficulties can be a catalyst to create new value.” He stated, “In life, difficulties are inevitable… No one in this world can live alone. Don’t be afraid to ask for help. Likewise, if someone asks you for advice, please listen intently with the attitude, ‘What can I do for you?’” The second was “What has been does not determine what will be, but what will be gives meaning to what has been.” He stated, “In the future, when you are choosing a career path, a place of employment, or anything else, you may be wondering, ‘Is this really the right choice?’ Or, after you have made your choice, you may feel that ‘This is not how it was supposed to be.’ I believe that the important thing is not what you choose, but what you do after you choose. I was on the verge of great global success but was unable to witness it. But I have been valuing what I enjoy, what I like, what I want to do, and as a result, I am living very happily now. If you ever lose your way in the future, I would be happy [if you] remember that there is someone living life like this.”

SPICE is grateful to Sabrina Ishimatsu for organizing this special online session. SPICE hopes to feature another musician in a second special online session in 2025.

As nations grapple with an increasingly competitive global talent landscape, a new study, published in the journal World Development, suggests that countries should rethink their approach to developing, attracting, and retaining talent. To address the need for a more complete understanding of cross-national variation in talent development strategy, the study proposes Talent Portfolio Theory (TPT), a novel approach to studying and improving human resource development.

The researchers, Stanford sociologist Gi-Wook Shin, the William J. Perry Professor of Contemporary Korea and the director of APARC and the Korea Program, and Haley Gordon, a PhD candidate at Stanford’s Department of Sociology, draw on the principles of Modern Portfolio Theory, a well-established framework in financial investment literature, to propose a new framework for talent development.

The new framework, TPT, views a nation’s talent strategy much like an investment portfolio, emphasizing the importance of diversification, risk management, and rebalancing. Shin and Grodon examine Japan and Singapore as case studies to illustrate how the TPT approach can help scholars, policymakers, and businesses better understand and optimize talent development strategies.

The study is part of the Talent Flows and Development research track of the Stanford Next Asia Policy Lab (SNAPL). Housed at APARC and directed by Shin, SNAPL is a new initiative committed to addressing emergent social, cultural, economic, and political challenges in Asia-Pacific nations through interdisciplinary, policy-relevant, and comparative research.

A Fresh Perspective on Talent Development

Talent development has long been a priority for nations aiming to boost economic growth and compete globally. Traditionally, countries have focused on building human capital — developing skills and education among citizens — and social capital — strengthening networks and relationships that facilitate cooperation and innovation. Existing strategies, however, often overlook the interconnected nature of various talent flows, including the movement of domestic talent, international talent, and diaspora engagement.

Just like financial theory evaluates a given investment (and its risk and return qualities) by how it impacts a portfolio’s overall performance rather than in isolation, TPT treats talent as a portfolio composed of four key elements, known as the “four Bs”: brain train (domestic talent development), brain gain (attracting foreign talent), brain circulation (movement of talent between home and abroad), and brain linkage (engagement with diaspora communities).

“In the study of national talent development, it is imperative to consider both the human and social capital facets of talent, as a country has multiple layers of talent available for use – domestic, diasporic, and foreign – each with different human and social capital potentials,” write Shin and Gordon. They propose TPT as “a better framework for illustrating and comparing different experiences and impacts of talent development at the national level, which is also key in offering policy prescriptions for human resource strategies.”

Insights from Japan and Singapore

Using Japan and Singapore as case studies, the authors demonstrate how countries can apply TPT to manage their talent portfolios. Japan's economic growth relied on two tiers of human capital: top-level scientists and engineers who adapted and integrated foreign technologies for domestic use, and skilled workers who grasped the fundamentals of these adapted technologies and carried out the manufacturing processes. With limited prospects for brain gain, circulation, or linkage, Japan developed these two layers of its workforce by relying on brain train, cultivating domestic talent for its industrial development.

In the early 1990s, however, Japan’s economy ran into trouble. Its system of brain train was well-suited for driving incremental innovation, but it became restrictive in the rapidly evolving landscape of the early 21st century, which demanded more disruptive innovation. “The Japanese model of human resource development necessitated a robust supply of domestic manpower which now became increasingly difficult to sustain, and a shrinking working-age population also meant labor shortage and reduced productivity,” say Shin and Gordon. “In the language of TPT, Japan urgently needed to diversify its talent portfolio beyond its reliance on brain train to address new risks.”

Recognizing the risks of a skewed talent portfolio, Japan began to rebalance its talent portfolio in the 2010s but has struggled with demographic decline and a slow pivot toward international talent. Despite efforts to internationalize higher education and attract foreign talent, Japan’s diversification of its talent portfolio has been stagnant and was hard hit by the COVID-19 pandemic.

In contrast, Singapore’s approach showcases the benefits of a well-balanced talent portfolio. The city-state’s aggressive pursuit of foreign talent (brain gain) and robust engagement with its diaspora (brain linkage) have made it a leader in global talent strategy. Singapore’s government has continually adjusted its policies, actively rebalancing its talent portfolio to maintain a competitive edge.

Singapore started rebalancing its talent portfolio in the 1990s, not only enhancing its efforts toward brain train but also expanding brain gain by internationalizing higher education and actively promoting a “work-migration” path. In tandem with its brain gain initiatives, Singapore also turned to its diaspora, fostering brain circulation and establishing stronger brain linkages. Through concerted efforts by the government and industry, Singapore has successfully produced and attracted creative talent that allowed it to remain globally competitive.

“Talent Portfolio Theory enables a holistic understanding of the various components of Singapore’s talent strategy and its evolution over time, from the country’s focus on brain train during its catch-up phase to its rebalancing with a successful brain gain, in addition to more recent forays into brain circulation and brain linkage,” Shin and Gordon explain.

Toward Fostering Cultural Diversity

TPT offers a powerful framework for crafting more resilient and adaptive talent strategies. As the global competition for skilled workers intensifies, understanding the dynamics of talent portfolios can help countries mitigate risks, capitalize on opportunities, and avoid the pitfalls of overly narrow approaches to human resource development. For instance, countries experiencing demographic decline, like Japan, can look to Singapore’s model of timely rebalancing as a guide for policy adjustment. Businesses also stand to benefit from TPT. The framework encourages companies to look beyond the availability of local talent and consider the broader talent ecosystem, including international talent flows and diaspora engagement.

Shin and Gordon emphasize that structural and sociocultural factors often limit policy options for building and rebalancing talent portfolios. Japan and Singapore illustrate that developed countries with abundant domestic opportunities are better positioned to retain talent and attract brain gain, whereas developing countries often experience talent outflows, favoring brain circulation or linkage (as seen in China and India). Additionally, while ethnically homogenous countries like Japan may prefer to rely on domestic and diasporic talent, multiethnic countries like Singapore can better attract foreign talent and engage in brain gain.

The contrasting experiences of Japan and Singapore underscore the critical importance of fostering cultural diversity to attract foreign talent. Singapore’s success with brain gain, compared to Japan’s more mixed outcomes, largely stems from its multicultural environment, shaped by policies that protect minority rights and actively promote respect for diverse ethnic groups. To remain competitive in the global talent market, countries must prioritize sociocultural policies that cultivate openness, tolerance, and diversity. By embracing these values, nations can attract the best and brightest minds, ensuring their place in a rapidly evolving global economy.
