HI Kirin!
Well if you ask lots of questions, and check out the search menu, im sure you will be able to gather lots of information for your trip!
How long are you going for?
Im going back to Japan in December, and I just found out about the seishin (sp?) 18 kippu, which is the train ticket that can be used for 5 consecutive or non consecutive days, sounds much more appealing than the Japan Rail Pass.
Found it on the search thingee here, so you can read more about it there!
Hmm this has gotten long!
Have fun in here, and dont be a stranger!
