Experience the Warm Hospitality and Daily Life of the Downtown Neighborhood
This community-based event is supported by local shops and neighborhood organizations. One of its greatest attractions is the warm, down-to-earth hospitality of Katsushika, a district known for its friendly, old-fashioned Tokyo charm.
Bring the event's complimentary Omotenashi Guide booklet, sent to participants in advance, to enjoy special offers at participating local shops, public bathhouses and other businesses. Runners can also make use of RUN Festa coupons for dining, shopping, and visits to traditional Japanese public baths. It's a wonderful opportunity to experience the local community beyond the race itself.
Explore a Nostalgic Showa-Era Town Featured in a Famous Japanese Film Series
Just a short trip from the event venue is Shibamata, one of Katsushika's most popular sightseeing areas. Here, you can discover Shibamata Taishakuten, a historic Buddhist temple featuring beautiful wood carvings and a traditional Japanese garden. The charming Taishakuten Sando shopping street is lined with traditional shops where you can sample Japanese treats such as kusa dango (mugwort rice dumplings) and freshly baked rice crackers.
This nostalgic neighborhood offers a completely different atmosphere from central Tokyo, with plenty of old-fashioned downtown charm. You can also visit spots associated with Tora-san, the beloved main character of Otoko wa Tsurai yo (It's Tough Being a Man), one of Japan's most iconic and long-running film series.
