Draft Planning travelling Japan

Hello Wan,

The basics look good but you do need to tweak your itinerary a little here and there.

One is visiting Kawaguchiko, I would do so as a day trip from Tokyo and travel on the next day to Kyoto. Doing the full train Kawaguchiko - Kyoto on a single day take up a lot of time and you won't be able to do much that way.

The other point is Takayama and Shirakawago, there's quite a bit of travel involved here as well. This this in half a day simply is not possible. I would recommend staying two nights for this in Takayama with (half) a day visit to Shirakawago.
Here's a bit more access information.

As for the JR Pass, definitely get one if you visit both Kyoto and Takayama in a 7 day period. You will make very good savings over normal tickets this way.

Hope this helps,
Daniel
