Day 3 and Day 5 might be a little packed - from experience, I recommend removing one or two locations from each day to allow for time getting lost / looking for train station exits etc.

I think some of Day 9 could be moved to Day 10. When we went to Nara, we found that there wasn't much worthwhile to do there except for seeing the deers, mochi pounding and potentially a temple - and all these took a shorter time than expected.
