Out and about with your children
Getting about in Tokyo, and Japan in general, is pretty easy. Although the crowds can be daunting, there are usually sections reserved in trains and on buses for pregnant women and people travelling with children. Look for 優先席 (yuusen seki) - they sometimes come in different colors but basically look like the sign below.
Most buses in and around Tokyo are non step buses and you can take your stroller on these buses easily. The entrance can be rather narrow though so, depending on your stroller, you may be asked to enter from the side doors on the bus.
Most of the large department stores and shopping centres have nursing rooms. Many of these will also have hot water dispensers for making up formula.
Look for 授乳室 (junyuu shitsu) signs. Often they will be marked with a baby bottle symbol.
