is a Shingon temple in Ogà Âri, Fukuoka Prefecture, Japan. The temple, which is famed for its frog figurines, is commonly referred to as , while the formal name is Seieizan Nyoirin-ji .
The temple was founded on the order of Empress Kà Âken in 729 and consecrated by the monk Gyà Âki. In 1586, however, the temple was temporally shut down in the fire caused by war. Then, in the early Edo period, the main hall was rebuilt by Arima Tadayori (), the second feudal lord of Kurume Domain.
Today, the temple and its surrounding grounds receive more than 30 thousand visitors annually.
The former chief priest of Nyoirin-ji Temple went on a trip to China, brought back a frog figurine made out of jade and placed it in the temple. With that as a starting point, he began collecting frog figurines in 1992 with the goals of changing the atmosphere of the temple and attracting young people to visit. There are now more than 5,000 figurines placed in the temple.
About 2,500 Japanese wind chimes called fà «rin (風é´) are hung up at the temple during the summer. Visitors can buy a fà «rin for 500 yen, write their wishes on the paper hanging from the fà «rin, then hang it at the temple.
The statue of the Nyoirin Kannon is said to have been carved by the monk Gyà Âki. As a "hidden Buddha," it is concealed and can only be seen during the year of snake every 12 years.
