Dougu Matsuri is an annual festival held in October in Kappabashi, the wholesale district between Ueno and Asakusa that specialises in tools and kitchen supplies for the restaurant industry. Known affectionately as Tokyo's Kitchen Town, many shops here also welcome home cooks and the general public as you can also purchase items individually.
Over 100 stores will be participating in the event, where you’ll find great deals on cooking utensils, tableware, food samples and more. While the festival officially runs for a week, most of the festivities will be held on October 14, with events such as the local elementary school marching band parade (11am), tai chi stage performances (1.30pm), food trucks (10am-5pm) and even a character bento exhibition at the Taito City Life-Long Learning Center (10am-5pm).
