In addition, a 'Yakushi-ji Temple' was always built on the grounds of a Fuseya in which a Yakushinyorai (Bhaisajyaguru (Buddha able to cure all illnesses)) was enshrined as a honzon (principal object of worship at a temple, usually a Buddha or Bodhisattva).
また敷地内には必ず「薬師寺」と称し、医薬を司る薬師如来を本尊とする寺が建てられたという。
