A Hall over Fifty Metres Long
The Oomoto Mirokuden, a worship hall of 1953, stands at Baishoen, the Oomoto centre in Ayabe, Kyoto Prefecture (Agency for Cultural Affairs). Over 50 metres long, it is a hip-and-gable hall entered from the gable end and wrapped by a skirt roof, with a hip-and-gable entrance 10 metres wide on the west and layered hip-and-gable roofs over the inner sanctuary projecting behind.
Its main frame is of steel but clad in timber to look like a wooden building, and its vast hall has a coffered ceiling (Agency for Cultural Affairs). According to the Japan Tourism Agency, it is the oldest building at Baishoen, and many of the glass doors on three sides keep their hand-blown panes of 1953.
Why It Was Registered
The Agency registered it as a structure that would not be easy to reproduce.
