Tokyo, Japan, has seen record hot summers in recent years. (Photo: Tokyo image by Undersound from Fotolia.com ) For most of the year, the weather should be fine for traveling to Tokyo. The city typically has moderate weather, and it's comparable to the weather in the Mid-Atlantic states. This could be changing, as Tokyo has seen its summer temperatures increasing. The other problem with summer travel is that you could wind up traveling in typhoon season.
