Japan Weather

Here is a page with a nice collection of weather statistics on a monthly basis for selected cities.

The Weatherbase site has some nicely presented info:

• List of Japanese cities, each a link to the weather in each city


• Selecting a city leads you to a page of monthly average statistics (low temperature, average temperature, high temperature, precipitation, length of day[light])


• From each city page there are arrows pointing to the left and right; the arrows are part of a ring or cycle that goes through five distinct pages
