japanese summer is hot as H and very humid in most cities with temperatures usually around 30-35C, but sendai/akita/aomori/hokkaido areas stay relatively cool, around or under 30C most of the time, and relatively humidity free even during the middle of summer.

Depends on where you are in Japan. For example, if you're in a place like Nagoya, it's going to be really hot compared to a place like...Aomori or Sapporo or something where it's not particularly hot (imo).

The summers are generally humid, though. As far as the US goes, people from places like California, where the heat is dry and has very little humidity (close to nonexistent, apparently) has trouble dealing with it.
