It is considered good to change rice, salt, and water every morning and sake and sakaki twice a month (usually the first and the fifteenth of the month, or else a day remembered in connection with the saijin (the god to whom the shrine is dedicated) whose name is written on the enshrined shinsatsu).
米、塩、水は毎朝、酒及び榊は月に2度（通常は1日と15日、ほかに祀っている神札の祭神にゆかりの日）新しいものと取り換えるのがよいとされている。
