The Nakamoto Seishi Contemporary Art Museum

This museum is the hidden gem of Sendai. The location, right in the middle of residential area, might be a little hard to reach via public transport, but it's well worth your time. Aside from exhibitions, they also have live concerts (classical music, folk music) from time to time. Special mention for the architecture. So artful and magical. I feel like visiting a building designed by Antonio Gaudi himself.
