The moss phlox was beautiful, the strawberries were delicious, and getting up close to Mount Fuji was breathtaking – it was definitely worth the trip! The tour guide explained everything very carefully and was very approachable and helpful.
It was a very convenient experience from start to finish—booking was easy, and the group chat before arrival made coordination seamless. Communication with the driver was straightforward, and they ensured a safe and smooth drop-off at our hotel. The service offered great value for the price, especially considering the comfort and reliability. Highly recommended for hassle-free airport transfers.
Although I was taken aback by the last-minute change of the meeting time and location, overall it was pretty good. The tour guide was very friendly, the vehicle was very comfortable, and Mount Fuji was absolutely beautiful. I definitely want to come back again in my lifetime.
Our tour guide, Xiaoyu, was humorous and had beautifully done nails. She was very responsible and managed the itinerary well. Our driver was a skilled driver; he successfully reversed and entered the parking lot at Shiraito no Taki on his first try without missing a single spot. In the morning, we had just the right amount of time to play on the coconut tree swings and take photos at the Couple Rocks. After having Ichiran Ramen for lunch, we went to Dazaifu. Although it was Saturday and there were a lot of people, we still had plenty of time. Our last stop was in the evening when we took a boat trip on Yanagawa, which was very comfortable. The boatman was handsome and could sing very well. We had a great time all day!
