Marugame Genichiro-Inokuma Museum of Contemporary Art (MIMOCA) will celebrate its thirtieth anniversary in 2021. Under the concept of “an art museum as a health resort for the spirit,” it has been committed from its outset to exhibitions and other locally focused cultural activities. Artist Genichiro Inokuma (1902–1993) considered it important that the museum play a role that would offer healing and spiritual nurture to its visitors. Focusing on the story leading up to the museum’s founding as well as on its distinguishing features, we present a two-part report on the “health resort for the spirit” as Inokuma envisioned it.
