Oedo

Oedo, written with the long vowel mark as Ōedo, is a Japanese term that appears in historical and modern contexts. It is most commonly associated with Edo, the former name of Tokyo, and with the Edo period (1603–1868), an era governed by the Tokugawa shogunate. In later use, Ōedo is employed in the names of places and attractions in Tokyo that are themed around Edo heritage.

Edo grew from a small fishing settlement to the seat of power for the Tokugawa shogunate, fusing administrative control with a rapidly expanding urban culture. The period was marked by relative peace, a rigid social order, and limited contact with the outside world. Edo was renamed Tokyo in 1868 as the new imperial capital emerged during the Meiji Restoration.

The Toei Ōedo Line is a Tokyo subway line operated by the Toei Transportation authority. It is designed as a looping route around much of central Tokyo, with many stations in multiple wards. The line is known for its long trains and color designation magenta. It connects residential areas with business districts and interchange points to other rail networks.

Oedo Onsen Monogatari is a hot springs theme park in Tokyo's Odaiba area. It recreates aspects of an Edo-period town with indoor bath facilities, traditional cuisine, and shopping streets.
