It is believed that the names "Togudo" (東求堂) and "Dojinsai" (同仁斎), being those of well-known buildings at Jisho-ji Temple, were selected by Yoshimasa from the candidates listed by Osen (authority: Rokusodan-gyo Sutra 'Tohojin (literally, people residing in the east land) who sought to be reborn in saiho (literally, the west land) through reciting the name of Buddha' (東方人、仏を念じて西方に生まれんことを求む) and Kan Yu, 'A saint loves people equally without discrimination' (聖人、一視同仁), respectively.
同寺の有名な「東求堂」「同仁斎」の名は、横川が挙げた候補の中から義政自らが撰したという（それぞれ六祖壇経「東方人、仏を念じて西方に生まれんことを求む」、韓愈「聖人、一視同仁」より）。
