Hōun Memorial Gallery, Biographical and art museum in Sumiyoshi Yamate, Japan

The Hōun Memorial Gallery was an art museum in Sumiyoshi Yamate, Kobe, housed in a building designed by Kiyoshi Seike and completed in July 1970, with one basement and three above-ground floors. It opened in 1970 as the Ohara-ryū Art Reference Museum and was renovated into a museum in 1993. Its roughly 4,000-piece collection was about 60% Andean artefacts, shown in a second-floor Andean room, with an Ohara-ryū reference room alongside.

The gallery opened in 1970 as the Ohara-ryū Geijutsu Sankōkan, founded to honour Ohara Hōun, third head of the Ohara school of ikebana. It was remodelled in 1993 into the Hōun Memorial Gallery, designed by architect Kiyoshi Seike. General admission ended after 2010, and the museum closed in 2018 with the exhibition "Door to the Future - Reborn"; demolition began in 2024.

The gallery was founded to honour Ohara Hōun, third headmaster of the Ohara school of ikebana, and about 60% of its roughly 4,000-piece collection consists of Andean artefacts, among them Chavín bird-shaped vessels and a Wari skull-shaped pot. A second-floor room held Ohara school materials, and folk objects from Southeast Asia donated by ethnologist Miyatake Tatsuo were also shown.

The gallery closed in 2018 after the exhibition "Door to the Future - Reborn", and demolition work has been under way since 2024, so the building cannot be visited. Its former address is 4-12-70 Sumiyoshi Yamate, Higashinada Ward, Kobe; until 2010 it opened for two weeks each in spring and autumn, otherwise by reservation, from 10:00 to 16:00. The Hankyu Kobe Line's Mikage Station was a five-minute walk away.

The building's architecture itself received the Kobe City Architecture Culture Award, showing that the structure is regarded as an artwork in its own right, not just an exhibition space. Architect Kiyoshi Seike's modern design subtly merges functionality with aesthetic qualities.
