This is a whole different lifestyle than the US. Everything is very laid back and low key here. Iwakuni is the most populated section which is approximately 115,000.
The weather here reminds me of San Francisco. It stays pretty cool and with a good amount of rain each month. Typhoon season is from June-Nov. Typhoons cause for a lot of wind and rain and the base will usually shut down. Everything here is built to typhoon standards, so when a warning is issued, everyone goes home.
