First planning a trip without large tour group.

Hiya! I planning to go to Japan on 3rd week of May for 10 days. And I am newbie in this no tour guide group travel.

I plan to go to osaka as my arrival then departure at Narita.

Basically I planned to go around Osaka, Kyoto (but still goes back to Osaka for hotel) then Tokyo.

I am also wondering if any travel expert uses klook to book tour guide or just planned themselves?

And is there any recommendation to visit?
