Solo 14-day itinerary in March Tokyo/Osaka/Kyoto Recommendations?

I am planning for my trip to Japan around March, preferably when the sakura blossom is at it’s peak, since the first time I went to Japan, it was close to the middle of April and I had missed most of it. It was a week, and I didn’t get to visit everything I wanted to during that time, also with me being stressed out about reaching some of them, it was a bit of a miracle I made it to the other places.

While I plan to go to Osaka and Kyoto, I’m opposed to being there more than a day, due to the commute (to and back) and having to stay at more than one place if I were to stay at each for more than a day.

Some things to note:

1. I’m not a seafood person, so that’s gonna cross out a lot of places
2. I want to try mostly Japanese food, I’m tired of American food as it is
3. Since the onsen I had in mind at Odaiba closed, any alternatives within reason? As a co-worker recommended Kusatsu Onsen in Gunma, but I’m a bit hesitant with the commute

I don’t have much of a draft of the first 7 days, but there’s some spots to fill in some of it and another week that I haven’t planned yet, which is mostly because I’m still looking around.

​

* Cafe Benisica \[Very late breakfast\]
