Question: is icoca accepted in tokyo?
Answer: Since August 1, 2004, in a reciprocal agreement with JR East, ICOCA is also usable in the Tokyo-Kantō area. Conversely, the Suica card of JR East can also be used on JR West rail services. Since January 21, 2006, ICOCA cards can also be used at all locations accepting Osaka PiTaPa smart cards.
