8 Day ITE Tokyo Narita - Osaka - Kyoto - Tokyo

Hi there,

Yes, a 7-day Japan Rail Pass would be a very good cost saver here! You can use the pass to visit all these places. I guess my main concern would be that you'll be on a busy trip and sometimes it can be nicer to pace things a bit slower.

As for Mt. Fuji, you could plan on a stopover between Tokyo - Osaka for a few hours. Stations like Odawara, Atami and Mishima all make for good Fuji views.

Hope this helps!
