How to cancel Radiko by mail
Start with your account details
Put the email address on the account, the plan name and, if you can find it, the billing partner shown on your latest statement in front of you before you write: the request to Radiko is only as good as the details it quotes.
Put the request in writing
Because Radiko is dealt with in Japanese, the letter is written in Japanese (template ja). Subject: “件名: 解約依頼 – [your name]”. It requests an end to the subscription and to every further charge, plus written confirmation.
Mail it with tracking
Address the envelope to Radiko, 港区, exactly as printed in the next section. Certified mail gives you a tracking number and a delivery record.
Hold on to the receipt
Once the letter is delivered, the date on the receipt is the date Radiko was told. Compare it with your statements over the next billing cycle.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Radiko, check these
- Bundles and add-on channels can be billed separately from the base plan. Ask for every line to be cancelled.
- Check the billing date on your statement and send the request well before it, so the cancellation lands inside the current period.
- If an app store, phone carrier or TV provider bills you, the service itself cannot cancel it. Cancel with the billing partner as well.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

Cancelling a streaming or entertainment subscription
Streaming plans renew silently each month, and many are billed by a partner such as an app store or a TV provider rather than the service itself, so the request has to reach whoever actually bills you.
A letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.
