Haniwa (tomb figurines), Buddhist sculpture, Buddhist ceremonial tools - the founder of this museum's collection, Hosomi Kokoan was strongly attracted to religious art, particularly the subtle details of Heian period Buddhist painting and syncretic Buddhist-Shinto sculpture, popular in the middle ages. The museum also has a extensive collection of narrative handscrolls (emaki) from the Muromachi period, both in large and small formats (koe).
The Hosomi collection is also known for its decorative arts, namely makie and Negoro lacquerware, tea bowls and utensils, as well as room ornaments. Exhibitions often display these pieces alongside paintings and sculpture, giving a more complete sense of the arts at the particular period.
From Tawaraya Sotatsu to Kamisaka Sekka (1866-1942), the Hosomi Museum is second to none in its collection of Rimpa art. Began by Sotatsu (dates unknown) and Hon'ami Koetsu (1558-1637), and later developed by Ogata Korin (1658-1716) then Sakai Hoitsu (1761-1828) in Edo, this style of art combines traditional Yamato-e painting with ink painting techniques, as well as a more modern sense of design.
Common subject matter were birds and flowers, as well as classical Japanese literary themes.
From Momoyama to early Edo, leisure activities such as visiting temple/shrines, cherry blossom viewing, and theater became increasingly popular. The rise of the merchant classes meant a new patron class, one that demanded more secular art related to everyday life. This new style of genre pictures (fuzoku-ga) included woodblock ukiyo-e, ink paitings, portraits of beauties, and scenes of the city.
The Hosomi collection is known for its ink paintings by Hokusai and folding screens depicting Edo/Kyoto life. Aside from these genre pictures, the collection is strong in works by the Kano school, literati painting (bunjin-ga) and the individualist painter, Ito Jakuchu (1716-1800).
