How to cancel U-Next by mail
Get your account details together
You will need the email address on the account, the plan name and, if you can find it, the billing partner shown on your latest statement. Use exactly the details U-Next holds, so the request can be matched to your account.
Prepare the letter
The request is prepared in Japanese (template ja), under the subject line “件名: 解約依頼 – [your name]”: end the subscription, stop all further charges and confirm in writing to you.
Mail the letter with a receipt
Mail the letter by certified mail to the 品川区 address in the next section, and keep the tracking number.
Keep proof the letter arrived
Keep the tracking record with your copy of the letter. If U-Next bills you after the date it received the request, you have the dates to point to.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel U-Next, check these
- Access normally runs to the end of the period you paid for, so a cancellation does not shorten what you already bought.
- 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.
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.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
