Something wasn't right?
Mark it up.

An alert that came late, a number that didn't match, a screen that froze. Tell us what you saw — the way a proofreader marks a page — and we'll check it against the official record.

This form is not for emergencies.

Reports are read by a person, not a dispatcher, and not in real time. If someone is in danger, call 110 (police) or 119 (fire and ambulance). Follow your phone's government emergency alerts (緊急速報) and your local authorities.

What we do with it

We lay your report against the official record.

For an alert, we line up what you saw with what the Japan Meteorological Agency issued and what our server logged — second by second. Where the lines agree, we move on. Where they don't, that's the bug.

What we keep

Only what helps fix it.

We ask for your prefecture and city, never your exact location. Your email is optional and used only to reply. Screenshots are for checking this report. Ask us any time to delete a report — the reference number is all we need.
