Buy & Hold Inc. (Headquarters: Zushi City, Kanagawa Prefecture; CEO: Takahiro Yamaguchi), which operates the financial and entrepreneurial school 'Financial Free College', announced that on March 12, 2026, CEO Takahiro Yamaguchi (aka Lion Nii-san) conducted a financial education lecture at Zushi City Kotsubo Elementary School for approximately 60 fifth-grade students and their parents.
The FY2026 tax reform outline includes the creation of a 'Kodomo (Children's) NISA', which is scheduled to begin in January 2027. Opportunities for children to interact with asset management will undoubtedly increase in the future.
On the other hand, parental understanding is essential for decisions and actions regarding asset management. Therefore, the purpose of this lecture was to improve financial literacy at the household level by adopting a format in which both children and parents participate simultaneously.
■ Why 'Financial Education Only for Children' is Insufficient
Buy & Hold Inc. has been conducting financial education classes at elementary and junior high schools in Zushi City, backed by the fact that CEO Takahiro Yamaguchi is a high-taxpaying business owner in the city and donates to English education for local junior high school students.
'Making money is bad.' 'Entrepreneurship is difficult, I can't do it.' What became apparent while teaching at multiple schools is the negative image children have toward 'money'. In fact, a pre-lecture survey revealed that over 90% of the children had a passive or negative impression of entrepreneurship.
We believe that these values are heavily influenced by the words and mindsets of adults they encounter in their daily lives. Under these circumstances, even if a child shows interest, there is a distinct possibility they cannot take action due to opposition within the family.
Future financial education requires updating the understanding and recognition of parents at the same time as teaching the children. Given this background, we held this lecture in the form of 'simultaneous parent-child education' with parents in attendance, aiming to update the financial literacy of the entire family.
■ Dispelling the Belief that 'Entrepreneurship is Only for Special People'
Addressing the negative image of money, Yamaguchi first explained how to earn money by dividing it into two types: 'money earned through providing value' and 'money earned through exploitation'.
While money obtained through exploitation has negative aspects, money earned through providing value is accompanied by 'gratitude' and 'trust', and is returned to society through tax payments. Conveying this elicited a strong reaction from the children.
Yamaguchi also conveyed the importance of considering 'entrepreneurship' as a working style for the coming era. While traditional values like 'getting into a good university and joining a good company' are changing due to the evolution of AI and the spread of diversity, the perception that 'entrepreneurship is difficult' or 'I can't do it' remains deeply rooted.
Therefore, hoping that starting a company becomes one of their future options, he explained that entrepreneurship is just like 'driving a car'—if you follow steps like 'learning the correct knowledge' and 'practicing alongside experienced individuals', it is something many people can achieve.
■ Specifically Explaining the Importance of Investment and How to Start
Furthermore, Yamaguchi explained not only entrepreneurship but also how to get involved with companies through stock investment. Since joint-stock companies operate on a system predicated on returning profits to shareholders, in a capitalist society, investing is one accessible means of participating in this system as a 'receiver of money'.
- By starting with index investment rather than individual stocks, it is possible to diversify risks and achieve highly reproducible asset formation.
- The three principles of 'long-term, regular accumulation, and diversification' as the royal road to low-risk asset management.
- How successfully utilizing systems like the 'Kodomo NISA' starting in 2027 will lead to the first step in asset formation.
He explained these basic concepts, incorporating specific ways to begin investing.
■ The Ideal Form of Financial Education Starting from the Home
He also explained the difference between simple and compound interest, telling them, 'If children also use compound interest over the long term for investments, they can build a certain level of assets by around age 40.' Both children and adults appeared convinced.
With increased interest evident from both sides—such as comments like, 'If that's the case, I want to try asset management right away!' and 'Let's try experiencing asset management using New Year's gift money'—the lecture concluded.
What became clear once again from this lecture is that a child's financial literacy is closely related to their home environment. As long as adults continue to throw words like 'difficult' and 'dangerous' at children, their potential is unconsciously restricted.
Triggered by the start of Kodomo NISA in 2027, the importance of raising financial literacy at the household level is expected to grow further. Buy & Hold Inc. will continue to provide financial education opportunities that prompt a change in consciousness across the entire family, aiming to realize a society where children can choose their futures more freely.
