You know, in Japan, it is very tough to move by  public transport with a baby.
Because trains, subways and buses are usually very crowded in Japan.
And many staired will overwhelm us.

But keep trying!
I will show you the techniques how to mive by public transport with a baby (and a babybaggy) in Japan.

1. Trains (at Tokyo)
There are many train lines in Tokyo. Every train scheduled tight and peaple on the train hurry - anyway, they look like being hurry. Sometimes you will be tyred only to walk in the station in the crowded peaple.
I do not have any idea how to survive in such a crowded peaple. But you will soon be noticed that the crowded time is only around 8 a.m. and 6 p.m. because buisuiness peaple using public transport usually move at that timing.
