An intimate museum on the grounds of Okayama Castle holding samurai armour, Bizen swords and daimyo treasures, including three National Treasures.
The Hayashibara Museum of Art (Hayashibara Bijutsukan) is a small but exceptionally rich art museum set on the former Ninomaru grounds of Okayama Castle, just west of the castle's inner moat. Occupying the site of a onetime castle guesthouse, it offers one of the most concentrated displays of samurai-era art in western Japan and makes an ideal companion to a castle visit.
The museum opened in 1964 to fulfil the final wish of Ichiro Hayashibara, head of the successful local Hayashibara enterprise, who wanted his personal collection made public after his death. Its interior, some 6,800 square metres, was designed by the noted modernist architect Kunio Maekawa, a disciple of Le Corbusier, giving the compact building an understated dignity behind its traditional gateway.
The collection numbers around ten thousand objects and draws on two great sources: the treasures Ichiro Hayashibara gathered himself, and the daimyo heirlooms inherited from the Ikeda clan, the former feudal lords of Okayama. Together they encompass swords and armour, Noh costumes and masks, lacquerware, furniture, paintings, calligraphy and ceramics. The museum holds three National Treasures and twenty-six Important Cultural Properties. Its most famous piece is a fourteenth-century indigo-laced do-maru suit of armour worn by high-ranking samurai, while many of its Bizen swords and pieces of pottery are likewise designated National Treasures.
Because the galleries are deliberately small, the museum rotates its exhibits only four or five times a year, presenting themed selections rather than the whole collection at once. This gives repeat visitors something new to see, but it also means checking the current display is wise if a particular masterpiece is your goal.
A memorable aspect of the visit is the sense of place. You are standing on the actual grounds where the lords of Okayama once lived, with the black keep of Okayama Castle rising just across the moat and Korakuen Garden a short walk beyond. The refined objects on show once belonged to that very court, closing the distance between artefact and history.
The visiting experience is calm and brief, typically under an hour, with a small shop and rest area. As a historic-style building it has some steps; accessibility is partial, and staff can advise on the easiest approach. Spring is especially pretty, when cherry blossoms surround the castle and moat, though the museum is a pleasant, sheltered stop in any season.
Getting there is straightforward. From the east exit of Okayama Station, take the Okayama Electric Tramway on the Higashiyama Line to the Shiroshita stop, about five minutes for a flat 140 yen with IC cards accepted, then walk roughly five minutes toward the castle; the museum stands just outside the inner moat. Walkers can reach it from the station in about twenty minutes. JR Rail Pass holders arrive at Okayama Station itself at no extra cost via the Sanyo Main Line and Shinkansen, needing only the short tram ride to finish the trip.
A local's tip
Displays rotate only four or five times a year because the galleries are small, so time your visit to a rotation featuring the National Treasure armour or the Bizen swords if those interest you.
Best time to visit
Any weekday; combine with a visit to Okayama Castle right beside it
