Honkō-ji, Buddhist temple in Ōmachi, Kamakura, Japan

Honkō-ji is a Nichiren Buddhist temple in Ōmachi, Kamakura, with the mountain name Hokke-san. Its vermilion gate opens onto a courtyard with a large crape myrtle, a weeping cherry and an old ginkgo. The grounds include a Shōtoku Taishi hall, and the temple treasures include a seated statue of Nichiren with Shakyamuni and Tahō Nyorai behind it, plus a portrait statue of Tenmoku.

Founded in 1336 by Tenmoku, a disciple of Nichiren, as Shukusokuzan Honkō-ji on the site of Nichiren's street preaching in Kamakura. In 1382 Nichijitsu became second abbot and renamed the mountain Hokkezan. In 1608 the 27th abbot Nikkyō was punished by the Tokugawa shogunate for the fujufuse doctrine, and in 1660 the temple moved to Iida; the original site was revived in 1670 by Nichitei of Hikigayatsu Myōhon-ji.

The temple keeps two statues as its treasures: a seated image of Nichiren, flanked behind by Shakyamuni on the left and Tahō Nyorai on the right, and a portrait statue of the founder Tenmoku. The grounds also hold a hall dedicated to Prince Shōtoku. The neighbourhood around it was once called Tsujimachi, after the crossing of the Kuruma-ōji and Komachi-ōji roads, which survives in the name "Tsuji no Honkō-ji".

Honkō-ji stands in Ōmachi, Kamakura, a five-minute walk from the Ōmachi Yotsukado bus stop (Keikyū bus line 鎌31 from Kamakura Station East Exit) or from the Suidōro bus stop (line 鎌40 from Zushi Station). The grounds are entered through a vermilion mountain gate; the monument marking the site of Nichiren's street preaching stands before the gate.

The temple stands on the site of Nichiren's Tsuji preaching, and a monument to the Tsuji sermon spot is set before the gate; a second such monument stands in Komachi 2-chome. The temple is called "Tsuji no Honkō-ji" after the former Tsuji-chō district, named for the crossing of the Kuruma-ōji and Komachi-ōji roads.
