A Buddhist hall standing in Lake Biwa
Kaimonzan Mangetsuji Temple Ukimido Hall (海門山満月寺浮御堂, the Ukimido or "floating hall" of Mangetsu-ji) is a small Buddhist hall rebuilt over the water of Lake Biwa at Honkatata in Otsu, Shiga Prefecture, in 1937, and entered on the national register as a Registered Tangible Cultural Property on April 28, 2000. A stone bridge about 17 metres long and 2.6 metres wide runs out from the shore to a three-bay hall under a pyramidal hōgyō-zukuri roof, with a building area of 37 square metres.
What stands here now is the second hall on the spot in modern times. Its predecessor was knocked down by the Muroto typhoon of 1934, and the replacement, designed by Nishizaki Tatsunosuke, was finished three years later. The posts that rise out of the lake were remade in reinforced concrete at that point, so the timber hall now rides on concrete legs.
In 1982, when the lake level dropped, the hall was temporarily moved aside while its legs and the surrounding gallery were rebuilt. The Ukimido has kept its prewar outline, but what holds it up has been adjusted to the lake more than once.
Why the hall was registered
The Kaimonzan Mangetsuji Temple Ukimido Hall was registered as a building that contributes to the historic landscape. The Agency for Cultural Affairs describes it as an essential element of the scenic spot celebrated as Katata no Rakugan (Wild Geese Returning at Katata), one of the Eight Views of Omi. What earned the listing is not the age of the timber but the view that the hall and the lake make together.
Tradition dates the first hall here to the mid-Heian period, when a hall housing a thousand images of Amida was raised to pray for safe passage on the lake and for the salvation of all beings. A hall pushed out over the water expresses that prayer in built form, and the 1937 rebuilding kept the idea intact.
The fact that a 20th-century reconstruction was listed matters in its own right. It records how people in the early Showa era chose to restore a lost landmark: new materials where needed, the same composition on the water.
Where to stand
The best-known view is from the temple's Main Gate, looking due east. The doorless gate frames the Ukimido neatly on the water. From there, walk round to the shore end of the stone bridge. At this angle you see the four eaves of the pyramidal roof spreading level over the lake and the slender legs standing in the water.
Cross the bridge and you step onto the gallery that wraps around the hall. More than half of what you see from here is lake. Mount Mikami and Mount Ibuki lie to the east, the Hira range and Mount Hiei to the west, and on a windy day you can hear small waves slapping against the posts below.
The light changes the hall completely. At sunrise it becomes a black cut-out against the brightening lake; in the evening the water turns red and the hall is mirrored in it. On rainy days the horizon disappears and the Ukimido hangs alone in the grey.
Visiting the Ukimido
Once you have paid admission at the temple, you can cross the bridge and walk the gallery around the Kaimonzan Mangetsuji Temple Ukimido Hall. The hall is small and a circuit does not take long. Directions, opening hours and fees are on the Kaimonzan Mangetsuji Temple page.
Images of Amida are said to be enshrined inside, and the hall remains a place of worship. No official statement on photography could be found, so check at the reception before photographing the images. The gallery is narrow, so it is better not to set up a tripod there.
For a full view of the hall with the lake behind it, shoot from the shore before you cross. People come and go on the bridge constantly, so keep stops there brief.
