Seiko Kobayashi, a lawyer, is a former world-ranked competitive swimmer and graduate of the 3rd EY Japan WABN Academy, which commenced in November 2023. Kobayashi is a mentee of Michiyo Hirose and a student of Yuko Sasagawa, who presented her lecture, titled “Learn entrepreneurship from women entrepreneurs,” at the Academy’s third session.

At the WABN Academy, mentors are EY professionals who help mentees identify business challenges, provide advice and guidance, facilitate their growth, and offer emotional support.

In this interview, Kobayashi reflects on her motivations for participating in the EY Japan WABN Academy, as well as the mentorship she received, which is a core component of the program.

EY Japan WABN Academy 3rd Batch Student: Seiko Kobayashi

Seiko Kobayashi (Kobayashi): When I applied for the EY Japan WABN Academy, I was in my seventh year as a lawyer. As I thought on the future of my career, I felt that I was lacking in business sense. Having spent so many years as an athlete, my debut as a lawyer was delayed, and I had an urge to discover new worlds an outside of these two fields.

 

Michiyo Hirose (Hirose): Kobayashi joined the WABN Academy during a challenging period in her life. In January, while still in the middle of the program, she gave birth to her second child and was also planning to relocate. I was impressed by her determination to join the WABN Academy, even in such a challenging situation.

 

Kobayashi: When I joined the WABN Academy, I was in the midst of many struggles. I believe this made the mentorship I received even more meaningful to me. When we first met, Hirose listened intently about my background, which eased my worries. One of the reasons why I decided to become a lawyer is that I was profoundly disappointed by the persistent violence and harassment happening in the sports world. I explained to Hirose that I wanted to set up a consultation service for individuals dealing with violence and harassment in sports, and that I would start by focusing on female athletes. However, she noted that my viewpoint was influenced by a volunteer mindset.

 

Hirose: I remember sharing my thoughts with Kobayashi, as her mentor, on how to turn her future vision into a business, including potential business challenges and areas to focus on. One of the keys to making your passion sustainable is to transform it into a business. I remember telling Kobayashi that by involving other people, her project would become sustainable and that it would also create talented individuals who could follow in her footsteps.

 

Kobayashi: Yes. Hirose showed me specific examples of potential avenues to realize my idea as a business, which instantly shifted my mindset. I was also touched by her personal story.

 

Hirose told me that back when she was raising her children, there were no reduced work hour systems or babysitting companies in the area that met her needs. So, she presented a proposal to someone who was running a different business, suggesting how they could launch a babysitting service, and they eventually launched a babysitting business.

 

Normally, if faced with similar challenges, many people might give up on their careers; however, she made me realize that we can also explore ways to continue pursuing our careers rather than simply giving up. Her story inspired me to not give up on either my role as a parent or my professional career.

 

Yuko Sasagawa (Sasagawa): This episode illustrates how Kobayashi developed a business mindset through mentorship. Future participants of the WABN Academy interested in studying business will have the opportunity to receive personalized mentorship and guidance on business strategies and mindsets from EY professionals. This support is designed to alleviate their anxiety about entering a new field.

 

“Athletes possess the qualities of entrepreneurs. I hope they emerge as leaders in society.” (Yuko Sasagawa)

Sessions featuring external business experts are also a key feature of the EY Japan WABN Academy. Sasagawa was one of those business leaders who delivered a presentation at a WABN seminar. During her lecture, she discussed what she valued in building interpersonal relationships, as well as the struggles she faced in fundraising while managing a staffing company over many years.

Kobayashi mentioned that among the various insights shared by Sasagawa, she was particularly inspired by Sasagawa’s practice of always taking notes on the conversations she had when meeting someone new, so she could review and remember what was discussed later.

“If you want to build connections with people, it is very important to remember the conversations you had in the past. Sasagawa values each encounter, and I think that is why she has been able to sustain her presence in the business world for such a long time.”

During her interactions with Academy participants, Sasagawa observed something unusual among the athletes - a common lack of confidence. This prompted Sasagawa to explain to the Academy members, including Kobayashi, the reasons why women athletes possess qualities that enable them to succeed in business. Her remarks served as a significant source of inspiration to the members.

Sasagawa: That seminar at the 4th WABN Academy was my second time speaking as a presenter, but I found it very unusual how all the athletes seemed to lack confidence.

 

To me, their lack of confidence didn’t make sense considering their extraordinary perseverance, ability to relentlessly pursue their goals, leadership qualities, and resilience to overcome challenges in their sports.

 

Hirose: Yes, I felt the same. In fact, in Japan, there is a shared perception that it is difficult for retired athletes to have successful second careers, as revealed by a past EY survey, in which only 4% of Japanese female athletes responded that “transitioning to a different career after retiring from sports is easy.”

 

Kobayashi: I can relate to other athletes who say that they are not confident about themselves. In my case, I have spent many years of my life in the world of competitive swimming, so I had limited experience as a working member of society. That’s why I constantly lack confidence in myself.

 

Sasagawa: That’s a shame. There is a saying that "successful businesspeople are business athletes," which reflects the growing trend among executives to learn from the mindset of athletes.

 

It was frustrating to see women athletes lacking confidence at the WABN Academy, so I carefully explained how athletes can connect their entrepreneurial qualities to their next careers. I especially hope that outstanding women athletes can gain the skills to thrive as business leaders in society.

 

Hirose: Increasing the number of women in decision-making roles is the next milestone EY aims to achieve.

 

Sasagawa: An increase in female leaders will facilitate the development of women-friendly working environments and is expected to improve work-life balance. It will eventually lead to many positive changes, such as the emergence of new businesses and markets.

 

The leadership and decision-making skills of athletes are also beneficial in corporate management, so I hope to see more female leaders from athletic backgrounds emerge from WABN.

 

Kobayashi: I'm not sure how much I can accomplish, but after hearing Sasagawa's words, I've started to feel that it's ok to have a little more confidence in myself. Recognizing that the efforts I've made have some value is a significant step forward for me.

“Collaboration with the EY entrepreneur ecosystem has further strengthened WABN.” (Michiyo Hirose)

Participating in the EY Japan WABN Academy led Kobayashi to a life-changing opportunity. In January 2025, she was appointed as an outside statutory auditor for a company listed on the Tokyo Stock Exchange’s Prime Market through a referral from Sasagawa. Kobayashi remarked that she is enjoying her career as a lawyer more than ever.

The relationship between Kobayashi and Sasagawa has been nurtured via the collaboration between the EY Japan WABN Academy and EY’s global program to support entrepreneurs.

Sasagawa is a member of the 5Hundred Club, which provides study and information exchange opportunities for leading women entrepreneurs whose companies have annual sales exceeding JPY500 million. This club is a part of the EY Entrepreneurial Winning Women (EWW) program, which aims to recognize and support female entrepreneurs. Through EWW, EY provides business insights to female entrepreneurs and corporate owners, as well as networking opportunities among entrepreneurs, financial institutions, venture capitals, influential major corporations, and media outlets. By collaborating with the EY entrepreneurial network, WABN Academy fosters interaction between athletes and entrepreneurs.

WABN aims to create even more opportunities for female athletes to thrive by actively leveraging the EY entrepreneur ecosystem in the future.

Sasagawa: Among those who ardently listened to my lecture, Kobayashi left a particularly strong impression on me. I mentioned to the audience that many former top athletes are now building new careers as external directors for listed companies, and Kobayashi asked me, “I have never been offered such an opportunity. How can I become one of them?”

 

Hirose: Listed companies tend to seek external directors who already have experience with at least one company, so I am well aware of how difficult it is to get that first opportunity.

 

Sasagawa: That’s correct. However, when one day I was asked by a listed company if I knew anyone suitable for the position of external statutory auditor, Kobayashi’s face came to mind before anyone else’s. The company has a rich history and consistently embraces new challenges with a progressive mindset. This openness created a welcoming atmosphere for appointing Kobayashi, a lawyer, to take on the role of external statutory auditor for the first time.

 

Now that Kobayashi is gaining experience at her first company, I am sure she will receive many more job offers in the future. We can expect great things in her future.

 

Hirose: I am overjoyed to see how the relationship and accomplishments of Sasagawa and Kobayashi highlight the significance of EY's entrepreneurial network.

 

Indeed, Sasagawa's participation in the 3rd WABN Academy, while also being involved in another EY entrepreneurial program, has inspired and created opportunities for numerous Academy members, including Kobayashi.

 

Kobayashi: Through the WABN Academy, I was able to connect not only with Sasagawa and Hirose but also with athletes from different sports who were experiencing the same struggles as I was. I would not have been able to gain these valuable connections on my own.

 

I feel that EY’s initiative to leverage its entrepreneurial ecosystem underscores its focus as a company on fostering dynamic connections and building an inclusive society.

 

Sasagawa: Entrepreneurs tend to feel isolated, but networks like this can foster inspiration among them and promote mutual growth.

 

Hirose: The 4th EY Japan WABN Academy has fully incorporated collaboration with EWW into its program. The goal of the WABN Academy is to enhance collaboration with stakeholders both within and outside of EY, utilizing EY's accumulated insights to enrich the program.
