Dark Bricks in the Lining

Oyamazaki Villa, on the slopes of Mount Tenno in Oyamazaki, Kyoto Prefecture, was the country house of the Kansai businessman Kaga Shotaro (1888-1954); 6 structures built from the Taisho to the early Showa period, among them the main house, a tea room, a teahouse, a garage, a lookout tower and a tunnel, are registered (Agency for Cultural Affairs; museum).

The Rokando tunnel, of the early Showa period, was made at the south-east corner of the site as the approach to the villa (Agency for Cultural Affairs). It is 5.6 metres long and 3.6 metres wide, cut through rock and lined in brick as a flat arch, with a portal of cut stone on the front side.

Though small, it is decoratively made, with dark fired bricks woven into the brick lining (Agency for Cultural Affairs).
