Konbu-in, Buddhist nunnery in Nara, Japan.

Konbu-in is a Jodo-shu Buddhist nunnery in Horen-cho, Nara, with the mountain name Horen-zan. Its main hall, rebuilt in 1642, has a hip-and-gable roof with tiled shikoro-buki layering and a Jodo-shu interior layout with side aisles flanking the inner sanctuary. A covered corridor links the main hall to the guest hall, and the four-legged gate is carved with dragon and tiger figures, earning it the name Ryuko-mon.

Konbu-in's foundation is uncertain: temple tradition credits Wake no Kiyomaro with moving Emperor Shōmu's study hall here in 749–757 under the name Kōbun-in, while the Shichidaiji Nikki (1106) and Shichidaiji Junrei Shiki (1140) name Fujiwara no Momokawa, and the latter already calls it Konbu-in. It declined, was revived in the Azuchi-Momoyama period by the nuns Shinkei and Kōshū with a 200-koku grant from Toyotomi Hidenaga, and in 1665 Tokugawa Iemitsu's successor Ietsuna granted land in Hōren-chō, where it still stands.

The temple's name is read Konbu-in, not by its characters, and it was already called Kōfuku-in by 1140, as the Seven Great Temples Pilgrimage Record notes. The main image is a Nara-period dry-lacquer Amida triad, brought here at the early-modern revival; its original temple is unknown. Thirty-one embroidered cloths donated by Tokugawa Tsunayoshi's consort Zuishun-in, said to be the oldest surviving covers of their kind, are an Important Cultural Property.

The temple grounds are not open to the general public, so the halls and garden cannot be visited; the compound sits in Horen-cho, Nara. To reach the site, take a Nara Kotsu bus from Kintetsu Nara Station toward Jieitai-mae or Saidaiji via Hokke-ji, get off at Saho Shogakko-mae and walk about five minutes.

The halls are not the only designated items: the temple keeps 31 embroidered cloths donated by Tokugawa Tsunayoshi's concubine Zuishun-in, said to be the oldest surviving covers of their kind in Japan. The main hall, gate and mausoleum are separately listed by Nara Prefecture and city.
