Opened in 2006. It is a unique cultural facility that combines the functions of both a museum and a library, collecting, storing, and exhibiting manga, one of Japan's representative cultures, as well as conducting research, exhibitions, and events related to manga culture. The building is housed in the former Tatsuike Elementary School, which was constructed in the early Showa period (early 20th century). The museum has a collection of about 300,000 manga materials, ranging from caricatures and ukiyoe of the Edo period to current popular works and those from overseas. The museum also focuses on events and special exhibitions to spread the fascination of manga. On sunny days, visitors can read manga while lying down in the field.
