Tsurumi Line (Okawa branch)

JR East is a different railway from the subway. Tokyo Metro and Toei run the subway; JR runs its own lines across and around it, mostly above ground.

Your Suica or PASMO works on both. Tap in and out the same way and the right fare is taken, so an IC card is the simplest way to move between the two.

Paper subway tickets and subway day passes are not accepted, and a journey that uses both railways pays a subway fare and a JR fare rather than one combined fare.
