Hongan-ji Saginomori Betsuin, Buddhist temple in Wakayama, Japan.

Hongan-ji Saginomori Betsuin is a Jodo Shinshu temple of the Hongan-ji school in Wakayama. Its main hall, rebuilt in October 1994, has the worship hall on the second floor and the temple office on the first. The grounds also hold a storehouse, a mountain gate and Saginomori Kindergarten, founded in 1926.

The temple's predecessor, Shimizu-dojo, was founded in 1476 in Shimizuura, present-day Kainan, by Kiroku Tayu, who received the dharma name Ryoken from Rennyo. It moved to Kuroe in 1507, to Mirokuji-yama in 1550, and to Saginomori in 1563. In 1580, after the Ishiyama Hongan-ji surrender, head priest Kennyo stayed here and the temple became Saginomori Hongan-ji. It burned down in the 1945 Wakayama air raid; the current main hall dates from 1994.

The temple is also called Saginomori Gobo or Saika Gobo, after the Saika district where it moved in 1563. Its main annual rite is the Nison-e on 13 May, a service centred on a seated image of Shinran and Rennyo, which carries a handwritten inscription by Rennyo dated 1476. A kindergarten founded in 1926 operates within the grounds.

The temple welcomes visitors interested in observing religious ceremonies and spiritual practice. It is best to dress modestly and follow standard temple etiquette when visiting this active place of worship.

The temple keeps a seated image of Shinran and Rennyo together, the Nison Renza-zo, whose back inscription in Rennyo's own hand is dated 1476. That inscription is thought to be the origin of the temple's foundation legend, since no record shows Rennyo visiting Kumano that year.
