The surviving framework of Yushukan was to be removed, but Goichi TAKEDA, a builder of the Doshisha Girls' School, recommended repairing and preserving the building. Yushukan was finally preserved by making reinforced concrete walls (wall thickness: 15 cm) at inner surface of the outside walls.
燃え残った有終館の駆体は撤去の予定であったが、当時隣の同志社女学校の建築を手がけていた武田五一が修理・保存を勧告、結局外壁の内部に15cmの鉄筋コンクリートの壁を作る方法で保存した。
