[6] In 1966, Tamai began appearing as a regular guest in a weekly traffic accident prevention corner on the Katsura Kokinji Afternoon Show (TV Asahi), showcasing problems such as the rise in auto insurance premiums and campaigning for the introduction of corporate manslaughter in the Penal Code of Japan.

[11] Among the young talents Tamai recruited into the organization, there were future National Diet members Takashi Yamamoto and Osamu Fujimura.

[15] Tamai, who opposed the presence of revolving door personnel, ultimately decided to create a new, strictly non-political association in support of all orphaned students.

[17] After the Great Hanshin Earthquake of 1995, Tamai started working on providing support for children who had lost one or both parents in the disaster, as well as conducting a comprehensive survey of all previous student loan recipients.

[19] In 1999, Ashinaga raised funds from donors in over 150 foreign countries, as well as Japan, and used these resources to build Rainbow House, a facility for the emotional care of orphaned children in Kobe.

The goal of this project is to foster future leaders who will bring positive change to their home countries and work to reduce poverty in the region.
