Kansai (KIX) - Mt Koyasan - Kyoto - Tokyo - Niigata - Tokyo

Hi Dom!

A lot of your travel is covered by the JR Pass (including Echigo Yuzawa, Niigata and Kusatsu onsen), but some area's can't be reached by JR (namely Koya and part of the way to Mt Fuji). I do think that a 7 day JR Pass be most cost efficient but looking at your itinerary I see that planning a round a 7 day JR Pass could be hard. What I would recommend looking into is to see if you could plan your itinerary in such a way that you can cover most of your long distance travel and be in Tokyo when the pass expires. You could for instance delay your visit to Fuji until you reach Tokyo, the because Fuji is best reached via express bus from Tokyo and the JR does not go all the way to Fuji.

In short, what I would do is buy normal ticket for your visit to Koya and around Kansai (Osaka and Kyoto) and than start using the 7 day JR Pass for your long distance travel starting with your trip to Fuji/Tokyo and try to cover as much travel with it as possible.

As for shipping the JR Pass to you, the Pass is dispatched using Fed-ex wish is very quick and reliable most order arrive next day within the EU, UK and US. I had one pass shipped to me in Japan once, it was send on a Monday and arrived on Wednesday morning, so even that was quick. You can read more about shipping times here.

Have a great trip in Japan!
