I am visiting Japan. I heard that it's a good idea to have a rail pass. Do these rail pass cover trips to Mt.Fuji?
The Japan Rail Pass is fantastic and will save you the cost of it many many times over. In case you don't know you have to buy them BEFORE you arrive in the country.
They don't cover ALL rail networks - there are some private lines, and the Tokyo subway isn't covered for example, nor are the festest Shinkansen's (Bullet trains) - but it will cover travel to Mt Fuji (I think) although I've never particularly wanted to do that particular trip myself.
We used these passes last year and toured Southern japan all the way to the very bottom of Kyushu. Fantastic.

I also think it depends how many cities you plan to get to, and if you strongly desire a trip on the bullet train as part of the experience. There are also buses that could be cheaper if you just want to go to Mt. Fuji, or another nearby city such as Kyoto. over 6 years ago
