Yukio Tabuchi Memorial Hall, Art and biographical museum in Azumino, Japan.

The Yukio Tabuchi Memorial Hall is an art and biographical museum in Azumino housing a large collection of mountain photographs, photographic equipment, and insect specimens. The collection includes thousands of original images and personal equipment used by the naturalist during his work.

Yukio Tabuchi (1905–1989) was a mountain photographer and researcher of alpine butterflies who climbed repeatedly in Azumino and the Northern Alps, holding that knowledge read from nature is the most correct. The city-run memorial hall opened in July 1990, the year after his death, and holds about 73,000 items, including his cameras, tent and other climbing equipment.

The exhibition space features rotating displays of local and professional photographs alongside Tabuchi's extensive mountain documentation. His work offers insight into how the Japanese Alps appeared through the eyes of someone who spent decades studying them.

The museum is about a 20-minute walk from JR Hakuyacho Station on the Oito Line; from Toyoshina or Hotaka stations it is roughly 10 minutes by car, and about 5 minutes by car from the Azumino interchange on the Nagano Expressway. The Azumino wasabi field spring-water park is close by. On request, visitors can watch a video library of three roughly 15-minute films on Tabuchi's work.

The exhibition displays climbing gear and cameras that Tabuchi used during his mountain expeditions, revealing how he managed his work in harsh conditions. These personal items give visitors direct insight into the practical challenges he faced in the field.
