Going to Japan, Is June a good month?

Hey everyone, I'm going to Japan for vacation this summer. I'll be graduating in late May and planning to travel in early June. Anyway, I know that it is rainy season in June so I don't know if that's a good idea. I mean should I ignore the season or wait until July or August? These are the places I want to visit (I'll be around Tokyo):
Mount Fuji (climbing if possible)
Tsukiji market
Ramen museum in Yokohama
One of the hot springs
Kobe
There are many other places that I'll be visiting since I'll be there for about two weeks. Any opinion will be greatly appreciated.

Thanks!

June is rainy season. In Kobe June is clowdy, but not rainy (at least it was like this during the years I lived there). July and August are sunny, but also hot and humid. The big towns are especially hot. You can enjoy fire works and night views from high buildings or platforms on mountains during July and June. There is Obon season in the mid of August. A lot of Japanese travel during this time, so hotels and trains are full. Hotels are most expensive during this time.

If you can go to Japan only in the summer, I suggest that you go to Hokkaido or Okinawa (but Okinawa is extremely full from July 20th to the end of August). If you prefer going to the big towns such as Tokyo and Kobe, you should go in April, May, October or November.

Thanks alot for your comment OkinawaDolphin. It seems like October will be a good time but I don't know if I can wait that long. I might try to push it back to July or August.

I was in Tokyo around June of '03, and it was insane. Heat and humidity. The only real relief is at night and in ari-conditioned stores. I'm from the Chesapeake area of the US and June in Tokyo was about the same if not a little worse.

My advice is go in June not in August ... I was in Japan this past August 2 - Sept 6 ... and the humidity the firt 3 weeks almost killed me.

June is far and away more pleasant than August.

Sure you might get some drizzly, cloudy days later in the month (in Tokyo the rainy season doesn't start until mid-June anyway), but compared to the sweltering humidity of August (temps up to 39 deg with at least 90% humidity), which can feel like sticking your head into an oven every time you step outside, I think pretty much everyone would find June a nicer time to travel.

Early June is just lovely- pretty warm some days, but nothing like the heat of August. If you can come in June, definitely do so- it would be crazy to choose August over June just to avoid a bit of drizzle. July can be as hot as August but has the worst part of the rainy season, so I don't recommend it at all.

Thanks alot everyone for your opinion. I would probably pick June then because the sooner, the better for me (can't wait!).

I'm intending to travel to Kyushu in the first week of June. Will it be raining very heavily everyday? What would temperature be like? Around 20-25 degs?
