The Ikegami Hyakuchikutei Collection is a collection of 1890 items, mainly modern literary materials, collected by Matsumoto City's writer Kisaku Ikegami (pen name Hyakuchikutei, 1978-221). This exhibition continues from the previous one and introduces works by haiku poet Ogiwara Seisensui.

Ogiwara Seisensui (1884-1976) was initially influenced by Masaoka Shiki and others, and later participated in the new haiku movement led by Kawahigashi Hekigoto. Although he later parted ways with Hekigoto, he produced works in a free and diverse style that was not bound by the typical five-seven-five format, and was active as a central writer of free verse haiku.

Isen-sui was born in Tokyo, but his father was from Ikeda-cho, Kitaazumi-gun, Nagano Prefecture, and his wife was from what is now Ueda City, Nagano Prefecture, making him an author with ties to Shinshu. He met Ikegami Kisaku in 1930 (Showa 5). From 1962 (Showa 37), he visited Matsumoto almost every year and deepened their friendship. The collection contains many of Isen-sui's works and related materials.
