A FEW THINGS TO KNOW
Good questions.
Here’s how the service works,
and what to expect.
What does NotifyJP do?
NotifyJP helps you watch for listings on Mercari Japan. Save your search criteria, review matching listings in your feed, and connect the notification channels you want to use.
Do I need to read Japanese?
You can start with English keywords and request Japanese suggestions. Review suggestions before saving: translations can be imperfect, and the listing itself may be written in Japanese.
Will I see every listing immediately?
Coverage and alert delivery times are not guaranteed. The service regularly checks listing feeds, and capture gaps, matching, queues, and destination availability can affect what you see and when an alert arrives.
Where can I receive alerts?
The app supports email, Telegram, browser notifications, and Discord webhooks. Availability depends on service configuration. Email and Telegram destinations require verification, and browser notifications require permission on your device.
Does NotifyJP purchase items for me?
NotifyJP provides listing matches and direct links. Purchases and any shipping arrangements take place outside NotifyJP.
How do I get access?
Join the waitlist below. Access is opening in waves. Pricing and subscription details will be available through the app; the current public service information is still in draft.
Is this an official Mercari service?
No. NotifyJP is an independent service and is not affiliated with Mercari. Mercari Japan is the currently supported marketplace.
