Moreover, based on the specifications that appear in the first part of item one under Article 2 of the Law for the Protection of Cultural Properties, namely, 'the designation national treasure shall include--for any items whose value, considered as a unified whole, depends in part on the land on which they were created or on any other item--any and all such land and/or items,' there have been cases where the land on which buildings that were designated national treasures were built is also considered part of the designation.
なお、文化財保護法第2条第1項第1号の「これらのものと一体をなしてその価値を形成している土地その他の物件を含む」という規定に基づき、国宝建造物とともに「土地」が併せて指定される場合がある。
