In the Otsuka Museum of Art, the fact that nothing in its entire collection of art is original is part of the charm. 

The museum in northeastern Japan houses over a thousand replicas of iconic art works: Leonardo da Vincis The Last Supper, all of Rembrandts self portraits, and a full-size reproduction of the Sistine Chapel.

Besides giving Japanese visitors a chance to see masterpieces too delicate to be transported abroad-- like Picassos Guernica which never leaves the Museo Nacional in Madrid -- Otsuka offers a certain kind of preservation. 

The paintings are reproduced, in original size and color, on ceramic panels that dont fade over time.
