Sumida Heritage Museum
Sumida Ward, a key hub in the Sumida River basin since ancient times and a flourishing center of commoner culture during the Edo period, is now known for the TOKYO SKYTREE. The Sumida Heritage Museum is dedicated to collecting, preserving, and exhibiting materials related to the history, traditions, and local culture of Sumida Ward.
The exhibition covers the history of Sumida Ward, including sumo and downtown culture. If you're interested in Tokyo's older neighborhoods, you'll find it pretty interesting.
