Recommendations on 2 weeks trip

Hi there! I will be traveling in Japan from January 6 - 20th and would love to get some suggestions for some must see places. I have already booked 4 nights of hostel in Osaka, and plan to go to Nara, Kyoto, and make my way to end the trip in Tokyo. I have purchased a JR pass as well. What should I see (where should I go)to make the most out of the JR pass and my time in Japan? Thanks in advance!

What's the length of time for your JR pass? And you're flying into Kansai and out of Tokyo?

Can't find better one.

Thank you for your links!!
I will check them out once I'm off work.

The JR pass is for two weeks, so I should be covered for the whole duration.
I am landing in haneda and will be leaving there as well. I figured I will travel west the first day and make my way east after a few days in Kyoto. Unless kobe has things that I should really check out.

Thank you again for taking your time to help me out! Much appreciated :)

To make a 2 week pass pay off, you will need to make at least one, if not 2 side trips from Osaka/Kyoto
Use www.hyperdia.com to check costs, uncheck the Nozomi..box, and think in yen: your trips will need to add up to more than the cost of the pass for it to be worth it.
Hiroshima/Miyajima; Okayama/Kurashiki;Himeji; Kanazawa; Nagoya/Takayama are all classics, and good to consider.
Good luck!
