A few words about me. I have been to Japan several times already, thus I visited a good chunk of the most popular sites. This time around I am mostly looking for more unique experience - perhaps going to less popular places and experiencing local side of Japan.
I will spend 9 days in Japan from middle of December:
Day 1 - Land in Tokyo and tour its streets for a day.
Day 2 - A day trip from Tokyo without using a Japan Rail Pass. Perhaps Mt. Fuji? I know it's not a climbing season, just visiting its surroundings if it's worth it. P.S. I have been to Nikko before and enjoyed it a lot.
Or stay in Tokyo and go to Ghibli Museum/Disneyland, but it's probably too cold for amusement parks in December?
Days 3 to 9 - Activate Japan Rail Pass.
During days 3 - 9 I am planning to go South of Tokyo. In have been to Miyajima, Hiroshima, Osaka, Nara and Kyoto, but I would like to stay in Kyoto again for a day. My plan is to stay only a day in each city, perhaps doing two cities in a day. I have done it before and it worked out pretty well.
To sum, any recommendations for days 3 - 9? So far I thought of Kyoto and Fukuoka only. By the way, the weather in December should be perfect for visiting an onsen. Any recommendations?
For leaving Japan I have Tokyo and Osaka as options. Possibly Fukuoka as well, but it's not a preference.
I know I am a bit vague, but hopefully you will come up with something.
Thanks a lot!
