Measures were therefore taken against the displacement and force that concentrates on the junctures between the soft wooden structures and the rigid RC structures, by safely transmitting the force to the joining area and wooden section and preventing brittle fracture. From the outside, the roofs of the day care rooms are consistent in their distinctive ridgelines running diagonally from opposite corners; inside, the use of different supporting beam structures utilizing circular columns, braces, beam strings, and other features give each room a distinctive character. The playroom has a symbolically shaped truss arching over the stage that supports the large shed roof. The wooden parts of the building follow wood-frame structural methods using locally milled Tokushima-grown cedar. 1：遊戯室。ランチタイムにトップライトから光が降り注ぐ。2：3歳児保育室。3–4：県産のスギ製材を用いた保育室の屋根架構。1: Playroom.
