Saikyō-ji, Buddhist temple in Hirado, Japan.

Saikyō-ji is a Shingon-shū Chizan-ha temple in Hirado, founded in 1607 by Matsura Shigenobu. Its main hall (hon-dō) was rebuilt in the mid-Edo period, and the three-story pagoda, erected in 1989, is among the largest of its kind in Japan. The main image is a statue of Kokūzō Bosatsu.

Saikyō-ji was rebuilt in 1607 by Matsura Shigenobu, first lord of Hirado Domain, on a site where tradition says Kūkai first burned a goma fire after returning from Tang China. A Sōtō Zen temple, Shōon-in, stood there; its abbot Ryūdon refused to move, so Shigenobu burned the temple with the monks inside and built Saikyō-ji on the ruins. Shigenobu's grave lies in the grounds.

Saikyō-ji belongs to the Shingon-shū Chizan-ha school, not Tendai, and is called the "Kōya-san of the West". It is the 77th stop on the Kyūshū 88 Sacred Places pilgrimage. The temple keeps treasures donated by the Matsura lords in its Reihōkan hall, including a silk Buddhist Nirvana painting designated an Important Cultural Property.

The temple is easy to navigate with marked paths and provided maps that guide visitors through the religious buildings and gardens on the grounds. Morning hours tend to be less crowded, allowing you to appreciate the structures and decorative details more easily.

The temple's reihōkan treasure hall displays items donated by the Matsura lords, including a silk hanging of the Buddha's nirvana designated an Important Cultural Property and a hanging Buddha image listed as a Nagasaki Prefecture cultural asset. The hall closes on Thursdays.
