Ajirochaya is a project that will convey its history and culture in the same location for the next 100 years and on.

The purpose of this project is to renovate and open up five buildings owned by Ajiroen, a long-established retail shop specialized in Japanese tea in Yokoyama-cho, Hachioji City, to local people as a commercial and cultural facility. Located seven or eight minutes by foot from the north gate of JR Hachioji Station, the rectangular plot is sandwiched between Koshu Kaido Avenue and a public walk on the north and south sides. On this plot five buildings stand close together: two storehouses (kura) built in the late 19th century to early 20th century, a Japanese-style house and a shop built immediately after World War II, and a reinforced concrete building built in the late 1960s to the early 1970s. As part of this project, a small town block was created as a conglomeration of the history of Hachioji and the consolidated elements of the community by rebuilding the shop, renovating the four other buildings, laying a garden path (roji) north and south through the elongated plot, and making a small open space garden (niwa) facing the public walk.

On the second floor of Ajiro Building lies a rentable space of about 50 square meters renovated from a recreational room in the former dormitory of Ajiroen. All the interior finishes in the recreational room were removed, and the minimum required facilities, such as a toilet and a sink were provided.

A patchy looking floor in a clear paint finish that was painted after removing the existing finish gives a uniquely unbalanced impression in contrast to the walls and the ceiling painted in white. The staircase from the first floor and the landing were given a rough finish that did not attempt to hide the traces of the patch-up work.
