3 day tokyo area itinerary advice

1 week until Tokyo! We’ll have 3 full days there. I was dreading making an itinerary because it just is overwhelming but I understand I need at least some structure. That said, here are three days I’ve come up with. Are these loosely circled areas doable for two reasonably fit adults in a day? Akasaka is our base.

1) Tsukiji fish market, heading west into Tokyo tower area, then into Roppongi

2) starting at Kodokan judo school, heading east to Akihabara, Ueno park, then Asakusa. (This is the one I’m most questioning)

3) Shinjuku & Shibuya

Here’s the link to maps where I’ve circled the general areas: https://imgur.com/a/Y211teM

Thanks for your help!
