Umi-Mori Art Museum, Art museum in Hatsukaichi, Japan.

Umi-Mori Art Museum is a museum in Ono, Hatsukaichi, Hiroshima Prefecture, founded in 1981 by the religious group Byodo Daie-kai. Its galleries hold Japanese art from the medieval to modern periods, centred on Kyoto modern nihonga by Takeuchi Seiho and his pupils, including several thousand sketches and photographs bought from Shibunkaku in 1985. A cafe looks across the Seto Inland Sea to Miyajima and the red torii of Itsukushima Shrine.

The museum opened in November 1981 as the Ojo-jo Art Museum, founded by the religious group Byodo-daie-kai to display the collection of its leader, Reikiyo Umemoto. In September 2005, after a full renovation of the interior, it was renamed Umi-Mori Art Museum. Its core holding is a group of materials by Seiho Takeuchi and his pupils, bought in bulk from Shibunkaku in 1985.

The core of the collection is material related to Takeuchi Seiho and his Kyoto disciples, bought in bulk from Shibunkaku in 1985: several thousand sketches, preparatory drawings and photographs. It also holds Utagawa Hiroshige's bird-and-flower prints, Chinese prints that influenced ukiyo-e, and perfume bottles from antiquity to the present.

The museum is about ten minutes by taxi from Miyajimaguchi Station on the Sanyo Main Line or Hiroden Miyajima Line, and about ten minutes by car from the Ono Interchange on the Hiroshima-Iwakuni Road. Parking is free, with space for 100 cars and 10 buses. A French restaurant, SEIHO OMBRAGE., and a dining spot called Mori no Kyukeisho stand on the grounds.

The museum's collection centres on Takeuchi Seihō and his Kyoto pupils, built from several thousand sketches, preparatory drawings and photographs bought in one lot from Shibunkaku in 1985. It also holds 600 volumes of the Song-dynasty Great Perfection of Wisdom Sutra, 400 of them printed at Qisha in Pingjiang during the Southern Song.
