The Stanford Japan Barometer (henceforth SJB), a public opinion survey on various topics including Japanese society, politics, and economy, is led by Stanford sociologist Kiyoteru Tsutsui, the deputy director of Shorenstein APARC and director of the Center’s Japan Program, and political scientist Charles Crabtree of Dartmouth College. SJB is one of the largest online surveys of its kind in Japan.

In fall 2024, SJB conducted a survey on gender and sexuality, including on the topic of optional separate surnames for married couples, as the LDP presidential election reignited the debate about this issue in Japanese society. SJB previously conducted a similar survey on the topic in 2022. Surname selection has also reemerged as a policy issue due to the growth of the opposition to the ruling LDP in the October 2024 subsequent general election for the Lower House of the National Diet (Japan's Parliament).

Below is an English translation of a recent GLOBE+ feature story on SJB's latest survey that sheds light on Japanese voters' views on this issue. This is the fifth installment in a series GLOBE+, an international news outlet run by the Asahi Shimbun, is publishing jointly with APARc’s Japan Program on SJB's work. You can read an English translation of parts 1-3 and part 4 in the series. The translation was initially generated via DeepL. The following translation was edited for accuracy and style.

Views on a Dual-Surname Option for Spouses

The issue came into renewed focus when former Environment Minister Shinjiro Koizumi, one of the candidates in the LDP presidential election held in September 2024, pledged to implement a selective married couple surname system. SJB therefore conducted another survey from September 25 to October 2, 2024, on the same themes as those used in the November 2022 survey on selective surname system, same-sex marriage, female Diet members, and outside directors. There were 9769 respondents, a little more than 1,000 more than in the previous survey.

The Japanese government has regularly been surveying this issue but as a result of changing the survey questions and the way they were asked between 2017 and 2021, support for the selective surname system dropped from a record high of 42.5% in the 2017 survey to record low of only 28.9% in 2021. For that reason, in SJB’s November 2022 survey and fall 2024 survey, respondents were randomly assigned to either of the two methods of asking questions from the government's 2017 and 2021 surveys.

The results showed that, among respondents assigned to the 2021 method, 26% preferred to “maintain the current system of married couples with the same family name,” 38% preferred to “maintain the current system of married couples with the same family name and establish a legal system for the use of the maiden name as a common name,” and 36% preferred to “introduce an optional system of married couples with different family names.”

On the other hand, among those assigned to the 2017 system, 21% said that “married couples should always take the same surname as long as they are married, and there is no need to change the current law,” 59% said that “if a married couple wishes to take the surname they had before their marriage, it would be acceptable if the law is changed to allow each couple to take the surname they had before their marriage,” and 20% and 20% said "Even if married couples wish to keep their maiden surnames, they should always have the same surname, but I don't mind changing the law to allow people who change their surnames due to marriage to use their maiden surnames as aliases.” In other words, 59% favored optional separate surnames for married couples.

Thus, the 2021 method of asking the question was more likely to result in fewer people supporting selective married couples. This is similar to Japan Barometer's previous 2022 survey, and it can be said that the government's 2021 survey showed less support for selective surnames because of the change in the framing of the survey questions.

As in the 2022 survey, SJB asked about optional separate surnames for married couples under certain assumptions, so as to reveal under what conditions public opinion would be swayed toward selective surnames. In SJB’s 2022 survey, respondents’ opposition was strongest when the precondition suggested separate surnames could weaken family ties or harm children and society. In the latest survey of fall 2024, however, no statistically significant causal relationship was observed, suggesting that public opinion on this issue has matured and no longer changes even when preconditions are added.

Furthermore, the 2024 survey introduced a new question about whether individuals would prefer to retain their maiden name if a dual-surname option for spouses was allowed. Among female respondents, 21.3% said they would “likely choose to do so,” 23.5% were “undecided,” and 55.2% said they “would not likely choose to do so.”

Commenting on these findings, Professor Tsutsui said: “Many older individuals and already-married women are accustomed to the current system, making it unlikely they would opt for separate surnames. The fact that only about 20% of the respondents would choose to change their surname could be a basis for some kind of legislation, since 20% of women feel inconvenienced. Furthermore, since the majority of women do not choose to have separate surnames, it is unlikely that the family system will collapse rapidly, as some conservatives worry. This may be a result that encourages the implementation of legal reform.”

Attitudes Toward Gender Equality

The survey also explored attitudes toward women’s advancement in society. As in the 2022 survey, respondents evaluated hypothetical political candidates for the Diet based on six attributes: age (from 32 to 82 in 10-year increments), gender, marital status, number of children, level of education, and professional background (10 types, including Ministry of Finance, Ministry of Economy, Trade and Industry, and Ministry of Foreign Affairs bureaucrats, corporate executives, governors, and local assembly members).

Two “candidate images” were created by randomly combining six attributes, and the respondents were asked to choose one in a two-choice format. The same question was repeated 10 times with different choices, and the responses obtained from all survey targets were tabulated and analyzed. The reason for the complexity of the method is that, from a statistical point of view, this allows the researchers to get closer to the “true feelings” (public opinion) of the respondents.

The combination of attributes that received the most responses, i.e., the “ideal candidate image” in respondents' minds, was the same as in 2022: female gender, ages 32 and 42, and occupation as governor or corporate executive. This aligns with the findings from the 2022 survey, indicating strong expectations for female leaders in their 30s and 40s. Indeed, Japan’s October 2024 Diet election mirrored these results, with a record 15.7% of women elected.

Views on Same-Sex Marriage

In addition, support for same-sex marriage remained high overall, with 43.7% in favor, 38.9% neutral, and 17.3% opposed. Support for same-sex marriage increased most when the following preconditions were added: "From the standpoint of human rights and gender equality, it is unfair to not recognize same-sex marriage," and "For gay people, not having their marital relationship recognized causes various inconveniences, such as inconveniences and disadvantages in their professional and daily lives, and a sense of denial of their identity."

On the other hand, when members of Parliament and outside directors were asked about their preferred combination of attributes, the least supported of the attributes of marriage was “people in homosexual relationships.”

“Married” was the most popular, as were “never married” and “divorced,” with the least support for those in a homosexual relationship.

“While there is a growing understanding of same-sex marriage in the private sphere, there seems to be a tendency for people to choose those who are within the traditional family system for roles holding public responsibility,” said Tsutsui.

I first learned about Sayama City, located in Saitama Prefecture, through its Sayama-cha—one of the three most famous teas in Japan. A thoughtful gift from an owner of a manufacturing company in Sayama City introduced me to this delightful tea, which quickly became a regular part of my daily life. Sayama’s vibrant tea culture, enriched by its lush plantations and lively festivals, reflects the city’s deep pride in this heritage. Never did I imagine that, a few years later, I would be working with a high school in this remarkable city.

In the spring of 2024, SPICE launched the Stanford e-Bunri course in partnership with Seibu Gakuen Bunri Junior and Senior High School (Seibu Bunri) in Sayama City. Under the leadership of the newly appointed principal, Dr. Pedro Marques, Seibu Bunri is dedicated to nurturing young Japanese leaders to be ready to thrive on the global stage. Principal Marques envisions the school as more than just a place for academic excellence; he sees it as a dynamic environment where students actively engage in their learning and tackle complex challenges. I was thrilled to contribute to this vision by bringing SPICE’s educational philosophy to Seibu Bunri by underscoring the importance of diverse perspectives, critical thinking, and innovation. Principal Marques commented:

In today’s rapidly changing world, education must go beyond the classroom and traditional academic boundaries. It is essential to provide students with real-world experiences that connect them deeply to the communities they live in and serve, while fostering their understanding and bonding with international communities. Partnerships like the one we have established with Stanford University’s SPICE program are critical to achieving this vision. They not only expose our students to global perspectives but also challenge them to apply their learning in meaningful ways that can make a difference locally and globally.

Modern education needs to equip students with the tools to navigate complexities and to build bridges between cultures, ideas, and communities. By integrating diverse topics such as diversity, women’s rights, and entrepreneurship into our curriculum, we aim to nurture empathetic leaders who are grounded in their heritage yet inspired to innovate and collaborate on a global scale.

This partnership is not just a program; it is a cornerstone of our mission to redefine education at Seibu Bunri. Through such initiatives, we are building a resilient community of learners and leaders who are prepared to face the challenges of tomorrow with confidence and a strong sense of purpose.

In September, we successfully concluded our inaugural Stanford e-Bunri course. Building on discussions with the school staff to address critical challenges in shaping a more inclusive, equitable, and innovative future in Japan, Stanford e-Bunri focused on three key topics: diversity, women’s rights, and entrepreneurship. Over the course of four months, 30 students participated in the virtual classrooms, completed reading and writing assignments, engaged in online discussions, and delivered group presentations on these topics.

Diversity

During our diversity-focused lessons, students were treated to lectures from Dr. Gary Mukai and Dr. Ignacio Ornelaz Rodriguez from Stanford University, focusing on diversity in the United States. Dr. Mukai explored the history of Japanese American experiences during World War II, while Dr. Ornelas shed light on the lives of Mexican workers through an overview of the Bracero Program. These topics, which represent significant yet often overlooked aspects of American history, provided students with valuable perspectives not typically covered in Japanese curricula.

The word “empathy” deepened my understanding of diversity. Both lecturers mentioned that empathy is really important in this diverse society; I felt that empathy will be the key point to building good relationships with people with different cultures and backgrounds.

In the last session of the diversity module, students considered the lessons learned about diversity in the United States and applied them to the issues in a Japanese context. They conducted research and delivered group presentations on various aspects of diversity, including race, gender, LGBTQ+ rights, socioeconomic status, disability, and age-related issues. These presentations offered valuable insights into the complex and multifaceted challenges surrounding diversity in Japanese society, encouraging students to recognize that diversity is not just a global concept but also deeply significant and relevant within Japan.

Women’s Rights

During the lessons on women’s rights, students learned from Dr. Mariko Yang-Yoshihara from Stanford University, who discussed the current state of STEAM education and her initiative to empower girls with STEAM education in Japan. Another lecture was given by Ms. Yukiko Kimura, former Founder and CEO at Genic Lab Inc. and Senior Product Manager at Amazon Web Services, who shared her personal journey as a female entrepreneur in Japan, including the challenges she faced and the resilience required to overcome them. Both sessions offered students a deeper understanding of the systemic and cultural barriers women encounter, while inspiring students to think critically about ways to foster equity.

Ms. Kimura’s quote made a lasting impression on me: “It is important to become the person you want to be, not the person others want you to be.” I will try to be who I want to be from now on, because limiting myself by other people’s expectations may change my life.—Seiji Yamakawa

In the final session of the women’s rights module, students researched gender-related issues and challenges in Japan and proposed solutions in group presentations. This exercise encouraged students to reflect on how they, too, could contribute to fostering greater gender equality in their own communities and beyond.

Entrepreneurship

The entrepreneurship module featured engaging and inspiring lectures from Mr. Kenji Niwa, Co-founder and CEO at Firstcard Inc., and Ms. Min Zhu, Co-founder and CTO at EnChannel Medical, both of whom shared their personal journeys and deep insights into the entrepreneurial mindset. Through their stories and expertise, the students gained a deeper understanding of the mindset needed to overcome challenges and failures, embrace innovation, and cultivate resilience—qualities that are essential not only for entrepreneurial success but also for thriving in any endeavor.

The lectures showcased inspiring stories of people who overcame obstacles to achieve their goals, highlighting the importance of resilience and continuous learning. I also realized that success is deeply personal, shaped by individual values rather than societal expectations. —Sora Ikeda

To conclude the entrepreneurship module and the entire course, students identified pressing social issues in Japan and proposed innovative solutions in a business pitch format. Their presentations received feedback from guest observer Mr. Christopher Chang, Strategic Advisor at Beenext Capital Management, providing students with valuable insights into real-world problem-solving. This interactive session not only encouraged creativity and critical thinking but also provided students with a glimpse into the practicalities of turning ideas into actionable solutions.

My experience working with Seibu Bunri and the students of the Stanford e-Bunri course has been both inspiring and rewarding. Through thought-provoking lectures, discussions, and hands-on projects, the students not only expanded their understanding of critical global topics but also delved deeply into examining key issues within their own society. This process challenged them to reflect on how they can actively contribute to creating positive changes.

I wish to express my heartfelt gratitude to my collaborators at Seibu Bunri for their amazing support and partnership. They are Dr. Pedro Marques, Mr. Toshiyuki Shijima, Ms. Tamaki Komaeda, Mr. Hiroshi Inoo, Mr. Joshua Moon, Mr. Opaon Cleo, Mr. Toshikazu Ishizaka, and Ms. Kayo Imanaga. I would also like to thank our guest lecturers who generously dedicated their time and expertise to speak for the Stanford e-Bunri course. Their contributions played a crucial role in bringing the course content to life, offering students a unique perspective on the topics of diversity, women’s rights, and entrepreneurship. Last but not least, I’d like to congratulate the dedicated students who participated in the course.

In closing, I have learned that Sayama-cha—compared to other tea plants—is characterized by its thick leaves. This is because the region’s cold climate sometimes causes frost in winter, making plants sometimes unable to survive without thick leaves. I am excited to see how the students will apply the insights and skills learned from Stanford e-Bunri to become resilient leaders who can thrive on the global stage despite inevitable “weather changes” in their lives.

Stanford e-Bunri is one of SPICE’s local student programs in Japan.
