Sudden heavy rain, strong winds, or lightning…
To prepare for sudden changes in the sky, be sure to check Weather Warnings and Advisories!

On this site, we divide Tokyo into the following five regions, making it easy to view warnings and advisories for each city and ward:

• Western 23 Wards

• Eastern 23 Wards

• Southern Tama Area

• Northern Tama Area

• Western Tama Area

You can see at a glance which areas are affected and what types of warnings or advisories have been issued.

Additionally, when any part of Tokyo is under a warning or advisory, a red banner will appear at the top of our website’s homepage saying “Warning/Advisory in Effect”.
Clicking on this red banner will take you to the warnings and advisories page.

Be sure to check before commuting, going to school, or heading out!

“Rumbling thunder kind of scares me… If you hear thunder, take shelter right away, nya! ⚡”
“When the sky looks suspicious, it’s safest to check warnings and advisories frequently, nya!”
