Around 1328, Ryogen relocated the temple as a basis of the preaching activities to Shirutani (or Shibutani) of Kyoto (in the area where Kyoto National Museum now stands), the former Buddhism-oriented place, and he put his efforts into promulgating the teachings throughout western Japan using a sacred light inscription of the name of Amida Buddha, a pictorial genealogy and Kyomyo-cho (a document with many names listed).
1328年（嘉暦3年）前後、了源は、教化活動の拠点を旧仏教の盛んな京都に移すべく寺基を京都汁谷（渋谷）（しぶたに）（京都国立博物館の辺り）に移し、光明本尊・絵系図・交名帳を用いて西日本一帯の布教活動に力を入れた。
