Yokohama Train Museum is really a very nice place. These images of miniature trains are only a drop in the sea of what this museum offers.
This museum holds a beautiful collection of trains from all over the world, and teaches about their history.
There are rare trains displayed behind glass walls but also toy trains, with which little people can play in selected areas.
If you get to visit Yokohama city, and you like trains, I gladly recommend this museum.
