The Koyasan Hidden Gems tour is a must-do activity when visiting Osaka, highly recommended. The meeting point was convenient, and our guide and driver, Hanazawa, was very thoughtful. He prepared AI-translated explanations in both Chinese and English about the origins of Koyasan and each attraction, playing them for us before we arrived at each site so we had the background knowledge before visiting. Since our trip was on a weekday, there were very few tourists, making it a very comfortable and peaceful experience. We tried Shojin Ryori (devotional cuisine) for lunch; 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 thoughtful. We were extremely satisfied with the day's itinerary.
