Zenraku-ji a été officiellement reconnu comme le 30e temple de pèlerinage le 1er janvier 1994.

Zenraku-ji est un temple bouddhiste Shingon à Kōchi et le 30ème temple du pèlerinage de Shikoku.

Kobo Daishi carved a Jizo statue here after praying for a woman in difficult labor. Pregnant women still visit the Koyasu Jizodo to pray for safe delivery, and parents honor babies who passed away.

The temple's water basin is supported by a carved Amanojaku, an evil demon from Japanese folklore. This unusual choice transforms a malevolent spirit into a humble servant of the temple.
