Planning my trip to Japan in October – Is it too much stuff? Some days seem quite unfeasible

i am planning to take a trip to japan solo. It si something i was planning for a long time and tried, from other itineraries and video to put toghether something i wanted to see.

I plan to do additional trip to esplore more of osaka, kyoto and tokyo for sure.

Any advice on how to improve it? or better balance the different days? Some of these days seems quite unfeasible and i´d like to explore freely some of these areas

• Stay in Asakusa – historical district
  • Day 1
    • Arrival at 12:00 AM, trasnfer to hotel and launch in asakusa
    • Sensoji Temple and a bit of Sumida park (after launch)

  • Day 2
    • teamLab planets for 9 AM
