When it’s hot and humid, walking around Tokyo can be extremely hard work — exhausting really. An endeavour that is only manageable due to an abundance of vending machines, and regular refuge in air-conditioned buildings.
But for little kids, the temperatures must seem even worse — something they simply can’t deal with. So what better way to see some trains,
or the sights of the city,
than by having your teacher take care of all the hard work?
