Contact
Send evidence that can improve a decision.
A public contact inbox is not yet available. This page states what the service needs and what will change when a verified contact channel is published.
1Price correction
Keep the exact page URL, product name, model or barcode, seller, displayed price, stock state, tax basis, and the date and time you saw it. A screenshot can help, but a direct source URL is better. Do not send payment details, order numbers, home addresses, or other private checkout data.
2Product request
Name the exact item and your home market. Add the decision you need to make, such as price, regional model, warranty, voltage, ingredients, luggage limits, or import restrictions. Requests with a concrete trip or buying question are more useful than broad category suggestions.
3Source or reuse question
Include the page and claim you want to discuss. Each comparison links to its evidence. Cite the original seller or authority for a source claim and cite What to Buy in Japan for the comparison or editorial judgment. Prices must keep their capture dates and caveats.
4Channel status
The founder must choose and verify a domain inbox before this page can publish an email address. Until that happens, there is no monitored public support channel and no promised response time. Agents must not infer an email address, phone number, street address, support commitment, or commercial relationship from the domain name.
