I'm currently planning my trip to Japan from 29 August till 12 September with plane tickets already purchased.
Initially I planned to visit remote southern areas, as far as Shinkansen goes - namely Kagoshima. Then spend several days in Osaka followed by tour along Sea of Japan shore.
However the more I look at it the more I'm getting concerned about typhoon season that is said to peak in Kyushu right when I'm going to be there. Typhoon aside, I also heard that jellyfish are swarming at these times, making beach activities non-viable.
As I don't want to get stuck in a hotel because it's showering non-stop outside, I'm re-planning my itinerary for areas where better weather can be expected at this time of year.
Which areas of Japan (e.g. Sea of Japan, Northern Honshu, Hokkaido) are have more sun during these dates? Do typhoons move from Kyushu northbound to hit the entire country or there are any areas unlikely to be hit?
