In the main building, the traditional furniture had been used for a long time by repeated repairs even after the completion of a new building, but in 2006 the bed clothes, the furniture, and the air conditioners were wholly renewed and it underwent a complete change.
本館においては新館完成後も従来の調度品が修理を重ねつつ長く使用されてきたが、2006年に寝具や家具、それにエアコンの全面的な更新が実施され、面目を一新した。
