Dainichibo Temple Dainichibô 大日坊
Area: Oami (Yudono)
Distance from the station: 45 minutes (by car)
Type: Spiritual
History:
It is said that Kobo-Daishi (or Kukai), the founder of Shingon Buddhism (the esoteric school of Buddhism specific to Japan) himself built this temple in 807.
This is where you will find Shinnyokai's mummy, remaining in the temple since 1786. According to the temple's monks, Shinnyokai decided to become a monk when he realized he was involved in an accident that caused two children's death.
Academicians say it was because he was involved in the murder of two men. Whom will you believe..?
Apart from the mummy, you will find an extensive collection of Buddhist statues, the 1800-year-old cedar tree Odan no Sugi 皇壇の杉, and relics that belonged to the Tokugawa Family.
