Rainy season on the bulk of the main island of Japan usually starts in the middle of June and lasts for about six weeks. Typhoon (台風, taifuu) season, on the other hand, usually starts in late August and last for roughly eight weeks. Most typhoons or hurricanes originating the Pacific Ocean usually weaken to “tropical storms” by the time they reach Ibaraki Prefecture, so although it can become extremely windy and rainy, it is unlikely to do much damage aside from blowing a few trees down.
In the event of an actual typhoon striking the area, your school may declare a “typhoon day” on which students (and perhaps you) will not be required to attend school. If you hear about an incoming typhoon:
- Around your place, secure or bring inside any items that may fly around in strong winds.
- Close storm shutters if you have them.
- Prepare for a day at home; buy food, water, etc. in order to wait out the storm.
- If you walk/cycle to school, find out prior to departure if it is safe to do so.
Avoid going outside in the middle of a typhoon unless it is absolutely necessary. Even an umbrella or water-proof clothing may not be able to protect you under such circumstances.
