This guide provides an overview of the Comment feature.

The Comment feature allows users to communicate with each other before making a purchase.

Note: This feature is currently being rolled out gradually and is only available to some users. Additionally, it may only be available on the mobile app.

The Comment feature allows overseas buyers to ask questions about items listed by Japanese sellers. The AI translates the messages and polishes the phrasing when necessary to support smooth communication, so you can interact with Japanese sellers with peace of mind. Additionally, if the answer to your question might already be in the item description, the AI will notify you.

1. Tap the "Comment" section on the item details page of the product you are interested in.
2. Enter your question in the text box and send it (posted comments are public).
3. Once sent, the seller will receive a notification. Please review the seller's response before deciding to make a purchase.

Posted comments cannot be deleted by the person who posted them. Only the seller can delete comments.
Comments deleted by the seller will be displayed as "Seller deleted the comment" This action cannot be undone.

The comment section is designed as a space for users to communicate with each other before purchasing. Sellers are not guaranteed to respond.

If you do not receive a response, we encourage you to look at other items and hope you enjoy shopping on Mercari Japan.

Comments are visible to other users.

Please refrain from entering personal information or using offensive language.

Please note that messages will be blocked if the AI detects offensive or discriminatory language.

• Can I ask questions even if I don't understand Japanese?
  Yes. If you type in your own language, the seller will receive an automatically translated version. However, because it is machine-translated, your exact intention may not always be perfectly conveyed.
• How do I request a price reduction (negotiate a lower price)?
  The comment section is intended solely for asking questions about the item. Please refrain from negotiating price reductions here.
• Can I return an item after purchase if the information provided in the comments differs from the actual product?
  Returns are subject to standard transaction rules and the return policy.
  Please use information obtained through comments only as a reference for your purchasing decision.
• Why was my comment set to private (hidden)?
  Comments deemed to violate Mercari Japan's rules may be hidden by Customer Support. If you believe this was done in error or have any questions, please contact Customer Support.

If your issue is still not resolved after reviewing the information above, Customer Support will investigate the situation for you.
