J-Alert System (Zenkoku Shunji Keiho Shisutemu) is a nationwide warning system in Japan launched in February 2007. The system now covers 100% of the municipalities nationwide. It is designed to quickly inform the public of various threats including:
- Volcano Eruption
- Severe Weather
- Special Emergency Threats
- Ballistic Missiles
What to Do When There is an Alert
In the event of a J-Alert warning siren due to a launch of a ballistic missile while you are on campus, please follow the procedures below:
- Stay inside the TUJ building. Move away from the windows, doors and walls, and, if possible, get under a desk or table and wait for the siren to stop. Remain sheltered in place until the J-Alert ends.
- After the alert has ended, TUJ administration will assess the situation. If it is confirmed that the missile has passed over Japan and landed in the sea, TUJ will inform students and staff and will close its operations for the day. The announcement will be made via e-mail and website.
If a missile has hit Japan, TUJ will close until further notice. Students and staff can use TUJ as a shelter or proceed to their homes once the public transportation resumes its operation or the road safety is confirmed.
TUJ will continue to monitor the situation and will provide updates via e-mail and website.
The Japanese Cabinet Secretariat has created a brochure for special emergency threats:
