What Is the Kongobuji Temple Inner Hall?
The Kongobuji Temple Inner Hall (金剛峯寺奥殿, Kongōbu-ji Okuden), once known as the Guest House, is a state guest hall built in 1933 at 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.
The hall occupies the western half of the head temple's grounds, on the site of Kozanji, a temple that burned in 1872. A Shingon seminary, the forerunner of Koyasan University, stood here afterward. When Kongobuji prepared for the grand memorial of 1934 marking 1,100 years since Kobo Daishi (Kukai) entered eternal meditation, it cleared the site and built a suite of reception buildings: the Okuden, a second guest hall, a linking corridor, an imperial envoy gate and a long boundary wall.
The works were supervised by the engineer Oura Tokutaro, who also took part in rebuilding the Kondo and the Konpon Daito pagoda on the Danjo Garan. The Okuden remains the temple's hall for distinguished guests, members of the imperial family among them.
Why the Okuden Was Registered
The Agency for Cultural Affairs registered the Kongobuji Temple Inner Hall as a building that serves as a model of its type. It is a single-storey timber hall with a copper-clad Irimoya-zukuri roof, entered on the long side, covering a building area of 330 m². It faces south over a rock garden, with a gabled entrance porch projecting from the front.
Inside, eight rooms sit in two rows of four. A veranda with a Kōran railing capped by bronze finials runs all the way round, and the southwest room is a formal reception room with an alcove. The carpeted entrance itself was used to receive guests of honor.
Kongobuji notes that the Okuden uses fine timber throughout and borrows deliberately archaic details, the medieval-style entrance above all. For a head temple in the early Showa period, this was how rank was expressed: less through size than through the quality of every joint and board.
Highlights of the Kongobuji Okuden
The feature to look for is the large Kaerumata, the frog-leg strut set in the gable of the entrance. The Agency's own description singles it out. Because the porch sits lower than the main hipped-and-gabled roof, the strut reads clearly even from across the garden.
The sliding-door paintings inside are by Ishizaki Koyo, a Japanese-style painter who took the Himalayas and Himalayan rhododendrons as his theme under the title "Sessan Kashin" (News of Flowers in the Snow Mountains). He died before the set was finished, so the panels at the back of the Kongobuji Okuden were never painted. It became his final work.
Around the hall lies Banryutei, a rock garden laid out in 1984. Covering 2,340 m², it uses granite from Shikoku to form a pair of dragons, male and female, rising from a sea of clouds raked in white Shirakawa sand from Kyoto. The dragons are arranged as though guarding the Okuden, so the garden and the older hall are now read together.
Visiting the Kongobuji Temple Inner Hall
The interior of the Kongobuji Temple Inner Hall is closed to the public, and Ishizaki Koyo's paintings are not shown on the standard visit. You see the building from the Kongobuji visitor route, looking across Banryutei toward the south-facing roof and the strut over the porch.
Photography is not allowed inside the temple buildings, but Banryutei itself may be photographed.
