Very detailed information tailored for Japan. Also integrates links (although via a browser) other hazards, earthquake, typhoon, etc. Settings are not very easy to understand especially if you can't read Japanese.

The app is just a wrapper around the Tenki website. It annoyingly forgets which city I was checking when I switch back to it. I wonder what's the point of having the app if we can just have several tabs of the Tenki website open? Thanks!
