After World War II, reinforced concrete treasure houses and depositories were newly established one after another in Shinto shrines and temples in each region, and there have been an increasing number of cases where the Buddha statues, etc. which had been deposited in the museum would be returned to the original temples.
第二次大戦後、各地の社寺において鉄筋コンクリートの宝物館・収蔵庫の新設が相次ぎ、博物館に寄託されていた仏像等は元の寺院に返還されるケースが多くなっている。
