The Otani Family Residence Main House (大谷家住宅主屋) is a large main house of fine timber at the foot of Mount Hongu of 1916 in Ashiyamadacho, Toyokawa City, Aichi Prefecture, and was registered as a Registered Tangible Cultural Property (structure) on October 27, 2017 (Agency for Cultural Affairs).

The Agency records a two-storey timber building, partly with a basement, with a tiled roof and a building area of 249 square metres, extended in 1994 and 2006; registration number 23-501.

A Formal Entrance and a Central Corridor

The main house of the Otani family, built in 1916, faces west on a site at the foot of Mount Hongu in northern Toyokawa (Agency for Cultural Affairs). From the formal entrance at the centre, two rows of two rooms, including the reception rooms and the Buddhist altar room, lie to the north, with living rooms and the kitchen to the south, all reached by a central corridor.

From the living quarters, stairs lead to a concrete basement and to the upper floor (Agency for Cultural Affairs). The frame is thick, and the timber, said to have been cut on the family's own hills, is of high quality.
