What would you do if you traveled with a group in Japan? You are the leader of the group.

Immediately issue gas masks or masks to the team members (in the absence of gas masks or masks, cover your nose and mouth with wet towels, or use clean clothes without towels) and lead the team members to a safe place to hide. Contact the travel agency and the Japanese Embassy in China, and contact relevant parties in China. After the earthquake and tsunami, leave the scene quickly and go directly to the Japanese embassy (remember not to lead the team members directly through the radiation area).

I hope it helps you.
