The Hayashibara Museum of Art is an art museum owned by the Hayashibara Group, and located at 2-7-15 Marunouchi, Kita-ku, Okayama, the site of a former guesthouse beside the inner moat of Okayama Castle. Its 6,832 m2 interior was designed by Kunio Maekawa.
The owner of the collection was Ichiro Hayashibara, and the museum was opened in 1964, to honor his final wishes to display his collection to the public prior to his death. The museum owns approximately 10,000 artifacts from Hayashibara's personal collection, including swords, armor, and pottery collected by Mr. Hayashibara, and Noh costumes, furniture, paintings, and Japanese lacquer from the Ikeda clan. The museum itself has limited space, so exhibits are rotated 4-5 times per year.
