If you can find your address in Japanese, this app is great for telling you when to put it what garbage. I just wish it had more English!

I've given this a 5 star purely to support the development of this app as it's a great idea. There's no Hakuba though, so I deleted it instantly. Would love to see more user-friendly ways to help people with their rubbish sorting (especially foreigners) it's such an important thing to do.

1/ Districts are NOT in English version. 2/ Areas are misspelt in romaji. 3/ No integration with Google calendar. 4/ No automatic/bulk notifications for EVERY rubbish day. 5/ Areas are not listed in alphabetical order. 1 star until fixed.

It seems like a great app for foreigners who need help with the garbage disposal rules and times, but unfortunately I am unable to use it because my municipality (Ashikaga City) is not listed in this app):
