How to cancel Netkeiba by mail
Gather your account details
Netkeiba will look your account up from what the letter says, so check the name and email on the account and, if you have one, an account or customer number first.
Draft the request
Postbye writes the letter in Japanese from our Japanese template, because Netkeiba's address is in Japan. It opens with the subject line “件名: 解約依頼 – [your name]” and asks Netkeiba to end the subscription, stop all further charges and confirm in writing.
Send it by certified mail
Mail the letter by certified mail to the 渋谷区 address in the next section, and keep the tracking number.
Hold on to the receipt
It shows the date Netkeiba received your letter. Check your next statement: no Netkeiba charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Netkeiba, check these
- Check your next statement: no charge should appear after the cancellation date.
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.

How cancelling by mail works
A subscription ends when the company records your request, not when you stop using it, and a letter is the record you can show later.
If a charge shows up after you cancelled, the letter and its receipt are what you put in front of the company or your bank.
