Travel in north of Japan in the summer

I will travel in north of Honshu from 15/7 to 30/8 2008.

Is it to hot at that time of year even if you travel north?

I will start att Niigata and then travel north along the west coast.

The only problems in July and August are sometimes the typhoons that blow through, canceling trains and ferries. If you're going to be in Japan during these months, the north is the best place to be. Even the Japanese head that direction, especially in August, so make hotel reservations before you get to places like Aomori or Hakodate.

Is it too hot at that time of year even if you travel north?

I don't think it ever gets too hot to travel anywhere in Japan. But especially Hokkaido and northern Tohoku and the higher elevations don't get too unpleasantly hot even during summer.

Two years ago I did a little summer trip in Tohoku and I can say that certainly, that year, it was hot in August. Air conditioning on in the car. Good beach weather. Too hot for much hiking.

Agree with Spenddrift. I took a trip 4 years ago to Hokkaido Furano for biking on 4 Aug. I got sun burn and it was scorching hot. And a week later, I arrived at Tokyo and it was extremely hot too. However, they were the two occasions that I remember was so hot, the rest of the trip was just fine. So I guess, you don't have to worry too much about the heat.
