HELP!!! with Itinerary (Nov5-Nov23) 18 day Trip

Hello I'm trying to plan my itinerary for my first time trip to Japan. I'm a 30 year old graphic designer travelling with a friend. We really want to get a feel of the country and its most important and beautifull places. Also, we really want to economize, since I have found that japan can be very expensive. So we really want to use a 14 day pass at the most. I've been doing some research in the internet and this is what I came out with. Even though we really want to make the most out of this trip, we don't want to be in a hurry jumping from place to place. So at a moderate pace would be fine.

NOV 5 - ARRIVE @ 8PM (Narita Airport) Stay nearby hotel

NOV 6 - TOKYO

NOV 7 - TOKYO > Kamakura > TOKYO

NOV 8 - TOKYO

NOV 9 - TOKYO > Nikko > TOKYO

NOV 10 - TOKYO > KYOTO

NOV 14 - HIROSHIMA-MIYAJIMA > Okayama > KYOTO

NOV 15 - KYOTO

NOV 16 - KYOTO > Nara > KYOTO

NOV 17 - KYOTO > KOYASAN ( staying in a temple? too expensive?)

NOV 18 - KOYASAN > KYOTO

NOV 19 - KIOTO > KANAZAWA

NOV 20- KANAZAWA (bus?) > Shirawago (bus?) > TAKAYAMA

NOV 21 - TAKAYAMA (bus?) > Matsumoto > TOKYO

NOV 22 - TOKYO > Hakone Or 5 lakes Mt Fuji > TOKYO

I would appreciate some advice on this itinerary. I just want to know what pass to buy and also start making hostel reservations.

Thanks :)
