The Koyasan Hidden Gems tour is a must-do activity when visiting Osaka, and I highly recommend it. The meeting point was convenient, and our guide and driver, Hanazawa, was very thoughtful. He had prepared AI-translated Chinese and English explanations about Koyasan and the origins of each attraction, which he played for us before we arrived at each site. This allowed us to have some background knowledge before our visit. Our trip was on a weekday, so there were very few tourists, making it a comfortable and peaceful experience. For lunch, we tried shojin ryori (Buddhist vegetarian cuisine); I didn't particularly love it, but it was worth trying. The visit to Seijin-in Temple was the icing on the cake. After completing the Okunoin tour, Hanazawa even prepared afternoon tea and green tea for each of us, which was incredibly considerate. We were very satisfied with the day's itinerary.
