It compares a bit closer to the Carolinas I think. However, Japan has a rainy season as well (usually about mid June to end of July) where it's very humid. It usually dries out a bit in summer (August to mid October) because the temperature goes up. I remember the first year I was in Japan trying to dry my shirts on the line in the rainy season. All of my clothing was cotton based and quite a lot of it got moldy on the line! Most Japanese clothes these days have at least some synthetics in it so that it dries quicker.
