The Edo-Tokyo Museum (江戸東京博物館, Edo Tōkyō Hakubutsukan^?) is a museum of the history of Tokyo, established in 1993. The main features of the permanent exhibitions are the life-size replica of the Nihonbashi, which was the bridge leading into Edo; the Nakamuraza theatre; scale models of town; and buildings from the Edo, Meiji and Shōwa periods.

The museum is located in Ryōgoku adjacent to the Ryōgoku Kokugikan. It was designed by Kiyonori Kikutake. The distinctive elevated shape of the museum building is modelled after an old storehouse in the kurazukuri style.

The Edo-Tokyo Open Air Architectural Museum is a branch of the Edo-Tokyo Museum.

Ryōgoku (両国^?) is a neighborhood in Sumida, Tokyo. It is surrounded by various neighborhoods in Sumida, Chūō, and Taitō wards: Yokoami, Midori, Chitose, Higashi Nihonbashi, and Yanagibashi.

In 1659, the Ryōgoku Bridge was built, spanning the Sumida River just upstream of its confluence with the Kanda River. Its name, meaning "two provinces," came from its joining Edo (the forerunner of Tokyo in Musashi Province) and Shimōsa Province. The neighborhood derived its name from that of the bridge.

The Forty-seven Ronin avenged the death of their lord, Asano Naganori, by breaking in to the mansion of his enemy, Kira Yoshinaka, in 1703. Part of the mansion has been preserved in a public park in Ryōgoku.

Ryōgoku Station opened in 1904, bringing rail transportation to the area.

It is regarded as the heartland of professional sumo. Most training stables or heya are based there. The first Ryōgoku Kokugikan stadium for sumo was completed in 1909. The present one was built in 1985 in the Yokoami neighborhood north of Ryōgoku. Three of professional sumo's six annual official tournaments take place there.
