The responsibility for this incident lies with WASABI. We will handle customer inquiries on your behalf. We regret the inconvenience and burden this places on you and ask for your understanding and cooperation.

WASABI INC.

Current status

Template message for your customers

Use it in emails, social media or on your website, as is or adapted to your situation.

[Important] Notice to our customers about suspicious emails

Thank you for shopping with us.

We have been informed that WASABI SWITCH, the order management system we use (provided by WASABI INC.), was accessed without authorization by a third party, and that order information (your name, delivery address, phone number, email address, order date, item, amount, etc.) was leaked. WASABI SWITCH does not store credit card information, so no credit card information was included.

Suspicious emails misusing this information — claiming, for example, that an item is out of stock and a refund will be issued — are asking recipients to contact a LINE account or enter card details. We will never ask you to contact us via LINE or to enter card or bank details. Please do not reply to such emails or access the links or LINE accounts they contain.

WASABI INC. has set up a dedicated contact point for inquiries about this incident:
https://incident-support.wasabi-inc.biz/en/customers

We sincerely apologize for the concern and inconvenience this has caused.

Questions from stores

What should we do if a customer contacts us?

WASABI handles customer inquiries about this incident on behalf of stores. Please direct customers to the "For customers" section of this page. A template message for customers is available on the "For stores" page.

We want to know whether our store is affected.

We are investigating with an external firm and will contact each store individually once the scope is confirmed.

How do we reactivate our accounts?

Tell our support team one account you wish to reactivate. After we reactivate it, log in and change the password immediately, then reactivate only the other accounts you need. See the second report for details.
