The Ryogoku area, located on the eastern bank of the Sumida River in western Sumida Ward, is widely known as the spiritual home of Japan’s national sport, sumo. During the Edo period, Ryogoku flourished alongside the bustling riverside, with Ekoin Temple becoming a historic site where early sumo tournaments were held, and where faith and everyday life intertwined. Today, Ryogoku is symbolized by the Ryogoku Kokugikan (Sumo Stadium), surrounded by numerous sumo stables and traditional restaurants serving hearty chanko-nabe, the signature hotpot of sumo wrestlers, creating a unique local atmosphere. Beyond sumo, Ryogoku is also a hub for experiencing Edo culture. The Edo-Tokyo Museum offers an immersive journey through the city’s history from the Edo period to modern times, while historic temples, bridges, and riverfront promenades reveal the nostalgic charm of Tokyo’s old downtown. Walking along the Ryogoku Bridge or the Sumida River Terrace, visitors can enjoy refreshing riverside views and imagine the bustle of old Edo. Cultural attractions such as the Sumo Museum, ukiyo-e collections, and traditional craft workshops also provide deeper insights into Japan’s heritage. The culinary scene is another highlight. From robust chanko hotpots to izakaya taverns and classic Japanese dining, Ryogoku offers a wide range of flavors. At night, the area buzzes with both locals and travelers. In summer, Ryogoku also becomes a prime viewing spot for the Sumida River Fireworks Festival, attracting large crowds to enjoy the spectacle. Altogether, Ryogoku combines sumo traditions, Edo-period culture, and scenic riverside experiences, making it a multifaceted and historically rich destination for visitors to Tokyo.
