Such a nice weather during spring in Tokyo. If you have the opportunity to travel to Japan, you really have to come in may! We had so many great sunny weekend. Perfect for some sightseeing...
The only problem is that it's not very easy to make a city trip with small children. They often get bored quickly...
So I (mostly) try to find some compromises. One of the best way to discover a new town and enjoy the kids as well is a river boat trip (if the city offer this opportunity of course!) In Tokyo you have enough rivers to give you this posibilty (love this city ;)
The most popular is a cruise down the Sumida River. So off to the Water Bus Station in Asakusa.
We started our trip with a wonderful view of the Skytree, the Sumida City Hall and the Asahi Super Dry Hall & Life Buildings...
