Cancel AWA

Log in first, then open this link. It is AWA's own cancellation page: scroll to the bottom and press 定期購入を解約, then confirm. Finish at least 24 hours before the period ends. If you pay through the App Store or Google Play, cancel there instead.

Go to AWA’s cancel page

Opens awa.fm in a new tab. Their login page forgets where you were going, so open this after you are signed in.

Signed up through Apple or Google Play?

Then AWA cannot cancel it for you. Use the store you paid through instead.
