This study shows the construction method and its characteristics of sheathed walls in the former Kaichi School building through the building survey. The building survey provided the plans for each member of the building framework and a detailed understanding of the composition and planning of building materials for walls. As a conclusion of this study, the wall surface composed of two pieces of Kabe-nuki (joinery) was unique, and this was the result of ingenuity which was aimed at realizing a Gi-yofu architecture (an imitative Western-style architecture) with sheathed walls.
