Traveling to Japan (3rd time) this June

Hey 👋🏼. I’m traveling to Japan this coming June 6-19. Been there two times but this trip, I would be solo. My dates are fixed and I know tsuyu starts in June. What would be the best itinerary for me? I plan to stay 3 nights in Kyoto and 1 full day trip to Osaka. Also planned to go to Sendai and Sapporo but entry and exit points are Tokyo, Haneda. Any suggestions or tips would be greatly appreciated. TIA.
