The main hall of Mangetsu-ji
Kaimonzan Mangetsuji Temple Kannon Hall (海門山満月寺観音堂) is the main worship hall of Mangetsu-ji, a Rinzai Zen temple on the shore of Lake Biwa at Honkatata in Otsu, Shiga Prefecture; it was built in 1766 and entered on the national register as a Registered Tangible Cultural Property on April 28, 2000. It is a modest single-storey timber hall, three bays across, with a tiled irimoya-zukuri hip-and-gable roof and a building area of 22 square metres.
Inside, the floor is laid with square tiles set on the diagonal, a pattern called shihanjiki. Rather than tatami or boards, the worship space has a hard, earthen-feeling surface, which is typical of Zen Buddhist halls and marks the temple's Rinzai identity from the ground up.
The principal image is a seated wooden figure of Sho Kannon from the Heian period, carved for the most part from a single block of wood, apart from the hands below the wrists. The statue carries its own national designation as a sculpture, and it is what gives the hall its name.
Part of a single temple scene
The Kaimonzan Mangetsuji Temple Kannon Hall was registered as a building that contributes to the historic landscape. The Agency for Cultural Affairs singles out the way it combines with the Ukimido on the lake to form one temple scene. Visitors entering the grounds have always read the main hall and the lake hall as a pair.
The building has been altered over more than 250 years. A recent repair changed the fittings between the front posts and added a kōhai entrance canopy. It is no longer exactly as first built, but the frame of a mid-Edo three-bay hall is clearly intact.
Of the five listed buildings, three date from the Edo period: the Guest Hall (1754), the Kannon Hall and the Main Gate (1812). The Kannon Hall falls between them, 12 years after the Guest Hall and 46 years before the gate.
What to look at
Start with the entrance canopy at the front. It is a later addition, a small roof projecting in front of the main hip-and-gable roof. Compare how the two meet and you can tell where the 18th-century structure ends and the recent work begins.
Walk to the side to see the triangular gable of the irimoya roof. At 22 square metres the hall is smaller than the Ukimido on the lake, which covers 37 square metres. That reversal, a main hall that is not the largest building in its own precinct, is part of what makes this temple distinctive.
From the front of the hall, look toward the lake and the pyramidal roof of the Ukimido comes into view. Holding both buildings in one frame is the easiest way to understand the "single temple scene" that the listing describes.
Visiting the Kannon Hall
The exterior of the Kaimonzan Mangetsuji Temple Kannon Hall can be viewed freely within the temple's opening hours. The Sho Kannon statue is described as closed to the public, so it cannot be seen on an ordinary visit.
Space around the hall is tight, and you will need to step back to fit the whole front into view. No official statement on photography could be found, so ask at the reception before pointing a camera into the hall.
Directions, opening hours and fees are on the Kaimonzan Mangetsuji Temple page.
