On Wednesday, November 12, 2025, we will officially launch "Kourei Baton," a community service for parents who are preparing for their first elementary school entrance exam.
While the birthrate is declining, the number of applicants for private and national elementary schools and international schools is increasing every year, especially in the Tokyo metropolitan area.
In the 2025 school year, some famous private elementary schools in the Tokyo metropolitan area have a multiple of more than 10 times (*1), making the "elementary school entrance exam" a realistic option for working families and families with diverse work styles.
On the other hand, there are many families who are "lost in the information" and are not sure where to start, do not have reliable information, and do not have anyone to consult.
Against this backdrop, Sunny Letus has released "Koureki Baton," a platform for parents to share their real experiences and connect the "baton of experience" with the next generation of families. With this in mind, Sunny Letus has released "Koureki Baton," a platform for parents to share their real experiences and pass the "baton of experience" to the next generation of families.

Our Vision
Make the examination experience more fair and open.
~The challenge we are solving~.
- The more useful information is, the less likely it is to be shared. The more useful information is, the harder it is to get out and the more closed the world tends to be.
- I'm not sure I'm doing it my way.
I would like to find my own axis by learning about the experiences of parents who have aimed for the same perspective and the same school of choice. - Lack of a safe place to ask for advice
I want to feel comfortable discussing concerns that are difficult to ask at cram schools or on social networking sites with senior parents who have no vested interest in the matter.
feature
- Experience-sharing community: People who have been accepted to famous elementary schools and intermediary schools share their real-life experiences of schools they applied to, interview strategies, and home study methods.
- A safe place to talk: Parents can dialogue with other parents in the same position about family and psychological concerns that they may not feel comfortable discussing with the school.
- Co-option of knowledge and teaching materials: worksheets, behavior observation measures, seasonal experiences, and other information that can be used at home are delivered in one place.
- Baton" system: Experienced workers to challengers, and then to the next generation. A reliable support model that circulates knowledge.
