Nestled in a long valley, Kamaishi proper is 14 km long by as little as 200m wide. When you're on the main road, it's difficult to get lost. That said, JR's Kamaishi line has four stops within the city, used by commuters, as well as a couple of bus lines. One caveat: the hamlets in the neighbouring valleys one to the north, and one to the south are technically part of Kamaishi, so a city bus may suddenly take a sharp left and take off through a mile-long tunnel.
