What Is the Kongobuji Temple Annex?
The Kongobuji Temple Annex (金剛峯寺別殿, Kongōbu-ji Betsuden), formerly the Guest Hall, is a 1933 reception building on the west side of Kongobuji, the head temple of Koyasan Shingon Buddhism on Mount Koya in Koya Town, Wakayama Prefecture, and it was registered as a Registered Tangible Cultural Property on March 13, 2025.
It belongs to a set of reception buildings raised on the former site of Kozanji for the great memorial of 1934, held 1,100 years after Kobo Daishi (Kukai) entered eternal meditation. The Betsuden stands east of the Okuden, the temple's state guest hall. Where the Okuden received imperial visitors, the Annex was planned for monks and ordinary believers.
Kongobuji describes it as Momoyama-style architecture. The hall hosted major meetings of the Koyasan Shingon order, and until 1983 it also served as a resting place for pilgrims.
Why the Kongobuji Betsuden Matters
The Agency for Cultural Affairs registered the Kongobuji Temple Annex as a model of architectural form. The single-storey timber hall has a copper-clad Irimoya-zukuri roof and a building area of 363 m², the largest in this reception group. It faces west over the rock garden, with eight rooms arranged in two parallel rows of four.
No bracket sets sit on the posts: the eave purlins rest directly on them, carrying a single layer of widely spaced rafters. A veranda with an out-turned railing wraps the rooms, and the southwest room has a formal alcove.
Set beside the Okuden, built at the same time under the same supervising engineer, the contrast is clear. The Okuden greets guests with a carved strut over its porch. The Annex holds back ornament and lets generous rooms and good timber carry the temple's standing instead.
Highlights of the Kongobuji Annex
Inside, the sliding doors were painted by the Japanese-style painter Moriya Tadashi. The western rooms form a sequence of flower rooms showing birds and blossoms through the four seasons. The eastern rooms follow Kukai from his voyage to Tang China to his founding of Koyasan.
The western rooms open onto Banryutei, a rock garden of granite dragons in raked white sand. Walking the rooms, you move back and forth between painted flowers and the stone garden outside the veranda.
From outside, notice how cleanly posts meet purlins. Without brackets, the line under the eaves stays level along the whole length of the Kongobuji Annex, which gives the long building its calm.
Visiting the Kongobuji Temple Annex
The Kongobuji Temple Annex is part of the standard visitor route through Kongobuji, and Moriya Tadashi's paintings can be seen on that visit. A sales counter inside the Annex also takes same-day sign-ups for the Ajikan meditation session.
Photography is not permitted inside the temple buildings, including the Annex, though Banryutei may be photographed.
