View the original at Japan Search →Article 2 defines a museum as an institution that collects, keeps and displays materials on history, art, folklore, industry and natural science for public use, carries out research on them, and which has been registered under Chapter 2 of this Act. The registration is not decorative. In law, an unregistered collection open to the public is not a museum.
The cool part. The definition of keeping is given as including raising. That single parenthesis is why a zoo, an aquarium and a botanical garden sit inside museum law in Japan: the collection is allowed to be alive. Article 1 also grounds the statute in the Social Education Act and the Basic Act on Culture and the Arts, which places museums in education first and culture second.
