Tokyo Metropolitan Government operates subways and buses in Tokyo

Tokyo Metropolitan Government operates subways and buses in Tokyo. It is called "Toei" which means the subways and buses services are operated by the Tokyo Metropolitan Government.

Subway(s) in Japanese is "chikatetsu".
Bus(es) in Japanese is "basu".

The following information is quoted from the website of "Toei" Transportation. I think the unlimited use of Toei subways and buses for one day for 700 Yen for an adult is a great bargain for a toursit.

"Toei One-Day Economy Passes allow unlimited use of Toei subways, Toei buses, the Toei Streetcar (Toden) Arakawa Line, and the Nippori-Toneri Liner for one day.

Please ask it with ' Toei Marugoto Kippu ' in the case of an inquiry.
