Uwajima City Date Museum

Uwajima City Date Museum in Uwajima, Ehime Prefecture, is a municipal museum dedicated to the swords, armor, crafts, documents, and cultural artifacts transmitted within the Uwajima Date clan — lords of the Uwajima Domain (宇和島藩) throughout the Edo period. The Uwajima Date clan descends from Date Hidemune (eldest son of the legendary Date Masamune of Sendai), making it a cadet branch of one of the most celebrated samurai families in Japanese history. The museum offers the only opportunity in Shikoku to experience the material culture of the Date warrior heritage at this level.

The sword collection at Uwajima City Date Museum is considered the finest in Ehime Prefecture, and one of the foremost in all of Shikoku. The holdings — spanning tachi, katana, and tantō transmitted through successive Uwajima Domain lords — include works designated as Ehime Prefectural Cultural Properties and as National Important Cultural Properties. Blades representative of the Kamakura through Edo periods are present, with major schools represented including Yamashiro, Bizen, Sōshū, Yamato, as well as blades with Sendai (Mutsu Province) provenance tied to the Date family's Northeastern warrior heritage.

The armor collection includes ōyoroi (great armor) and tōsei gusoku (full contemporary armor) from the Momoyama through Edo periods, offering a refined view of armor craft evolution in a high-status daimyo family context. The sword fittings collection — tsuba, menuki, kozuka — features quality Edo-period metalwork.

Located adjacent to Uwajima Castle (one of Japan's twelve surviving original castle keeps), the museum pairs naturally with a castle visit for a complete samurai culture experience. Approximately 1 hour from Matsuyama by limited express — easily combined with Dōgo Onsen and Matsuyama Castle itineraries.
