Thinking of taking that long Labor Day weekend to make an enjoyable trip to Japan (and also related to my search for cheap fares, mentioned elsewhere) -- but... will the weather, temp, humidity all over Japan be unbearably hot and unpleasant around that time? Is it already? Could heading north be the answer, or even there it's hot?
It wasn't when I left Sunday, July 14 but, I was reminded that it's unusually cooler this summer.
Sept is over a month out so I'd think it'd be warmer, at least near the beginning.
My thought is farther north is cooler but I've read places like Hokkaido has more rainfall then.
