Harajuku Museums

Harajuku is not exactly a museum area so the museum selection here is a bit low:
Treasure Museum
It is a building that was built in 1921. Its style, however, is a copy of the Ooyukazukuri (high floor style) of Azekurazukuri Shosoin (the Japanese National Treasure House in Nara).
In the building, various articles used by the Imperial couple during their lifetimes are displayed.
