A timber office dressed as stone

The Konkokyo Tosha Central Building (金光教徒社中央棟, Konkōkyō Tosha Chūō-tō) is a two-storey timber office built in 1927 in Otani, Konkō-chō, Asakuchi City, Okayama Prefecture, as part of the Konkōkyō publishing house beside the faith's headquarters, and was registered as a Registered Tangible Cultural Property on 27 October 2017.

Konkokyo Tosha, the publishing house of the Konkōkyō faith, occupies three buildings in an east-west row, and the central building was the last to be added, filling the gap between the west and east buildings.

The ground floor of the Konkokyo Tosha Central Building holds offices and a reception room, and the upper floor is now used for storage.

Why it was registered

The central building was registered as one that sets a model for design, the same criterion as the east building, while the west building was listed as a contributor to the historic landscape.

What the Agency for Cultural Affairs calls its unusual appearance comes down to disguise. The walls are rendered in mortar and painted to imitate stone masonry, and a tall parapet rises in front of the roof so the building reads as flat-topped. Behind it, the actual roof is a hipped Yosemune-zukuri roof covered in slate.

In the early Shōwa years, builders across Japan used timber framing and skilled plasterwork to borrow the look of concrete and stone. The Konkokyo Tosha Central Building applies that approach with unusual thoroughness to a small office.

What to look for

The building has a building area of 125 square metres and stands between its two neighbours, both clad in weatherboarding (Shitami-itabari). Only the central building shows a masonry-like face, and that contrast in materials is the easiest thing to spot from the street.

Look up at the front. The high parapet hides the slope of the roof and squares off the top of the building in a clean horizontal line. From an angle you may catch the hipped roof behind it, which shows how deliberately the facade was staged.

Up close, the painted joints give away the plasterer's hand. From a distance the Konkokyo Tosha Central Building passes for stone; near to, it is timber and mortar, and that double reading is its charm.

Visiting

The building is in use as offices and storage, and no announcement of interior opening was found. The exterior can be seen from around the plaza in front of the headquarters, together with the east and west buildings. As it is a working building, keep to viewing from outside and ask staff before photographing on the premises.
