I booked a private tour with Japanese support. Although the tour was shorter than planned because I requested specific places to visit and had a flight home that day, we were extremely satisfied. The lack of traffic might have also contributed to the shorter duration. In any case, everything went smoothly. The male guide was very friendly, easy to talk to, calm, and pleasant, which put us at ease. For private tours, they asked for requests regarding places to visit and things to do in advance, so I think it's a good idea to communicate your wishes beforehand. They also told us about clean restrooms along our route, which made our experience very comfortable. Overall, we had a truly pleasant time and it became a wonderful memory.
