Well Japan is on my bucket list, and is where I'm heading next year. If OP is interested in that check out
http://www.insidejapantours.com they're an excellent company specialising in organising trips only to Japan and can arrange pretty much anything you want, unless you like to DIY

Seriously, I can't wait and we have an excellent itinerary.
If the Pacific Northwest of US floats your boat and you like indigenous culture I know someone who can guide you around some of the Indian Reservations in that area, right up on the peninsula by Cape Flattery with the Makah Nation, down through to Forks and the Quileute Nation (Twilight series country).
And don't get me started on the highlights of Vancouver and Vancouver Island - love, love, love the place oo) oo)
So, as the gameshow host used to say press the button and gamble away" lol.
