Hokki-ji, Buddhist temple and National Treasure in Ikaruga, Japan

Hokki-ji is a Buddhist temple in Ikaruga featuring a three-story pagoda built using traditional Japanese wooden construction methods and standing about 24 meters tall. The complex includes multiple buildings from different periods spread across the grounds.

Hokki-ji traces its origin to Okamoto no Miya, the palace where Prince Shōtoku lectured on the Lotus Sutra; after his death in 622, his son Prince Yamashiro no Ōe converted it into a temple. In 638 the monk Fukuryō began a main hall housing a Miroku statue, and the three-story pagoda was completed in 706. The temple declined in the Heian period and came under Hōryū-ji; by the Edo period only the pagoda stood, and the lecture hall was rebuilt in 1694.

The temple's name means 'temple of the Arising Dharma'; it was long read 'Hokki-ji' but the temple now officially uses 'Hōki-ji', a change made for consistency with Hōryū-ji when both were registered as World Heritage. The main object of worship is a 3.5-metre wooden Eleven-Faced Kannon from the late 10th century, kept in the storehouse. The temple is stop 17 on the Shōtoku Taishi reijō pilgrimage.

The temple is a 2.5 km walk northeast of JR Hōryū-ji Station, or a short bus ride to the Hokki-ji-mae stop, served on weekends. The grounds are compact: the pagoda stands east of the former main hall site, with the lecture hall and treasure house nearby. The site is a National Historic Site.

Archaeological excavations revealed that the temple stands on the former site of Okamoto no Miya palace, where lectures on the Lotus Sutra took place. This connection to a royal residence shows the site's early importance to Buddhist learning in Japan.
