Hosts var­i­ous exhi­bi­tions of arts, crafts, and his­tor­i­cal mate­ri­als. This was orig­i­nal­ly the head­quar­ters of Aki­ta Bank. Aka means red in Japan­ese and ren­ga means brick, so the name means there­fore red brick build­ing. If you vis­it the near­by Kan­to muse­um, you can buy a joint tick­et for that and the akaren­gakan.
