Toyo University renamed it to "Hosuikai" in 1994.
When the founder Mr. Enryo Inoue lectured on the whole country to ask for donation to establish Tetsugakukan (former Toyo University) and Tetsugakudo (Nakano-ku, Tokyo) construction, he wrote his appreciation in words. His pen name was 'Hosui' and this is where we adopted the name.
"Hosui" disperses the word used for his hometown "Echigo country, Nagaoka Nishigumi Uramura (present Nagaoka-shi, Niigata)".
