KKday's Kumamoto trip was absolutely perfect! The tour guide was professional, attentive, and provided detailed explanations. The pace was relaxed and not rushed at all. We smoothly visited the vast Kusasenri Grassland, the tranquil Ushiomi Kumano Shrine, and the atmospheric Kurokawa Onsen. Even though Mount Aso was closed, they provided an alternative itinerary, and the route planning was excellent. The Kusasenri Grassland crater was stunning, perfect for taking photos at any time. Ushiomi Kumano was serene and peaceful, and Kurokawa Onsen had a strong Japanese atmosphere. The tour guide was patient and attentive throughout, reminding us of the weather and road conditions. Although they tried to sell us horse oil, I had bought some in Hokkaido before and it was indeed quite good. The driver was smooth overall, making the trip comfortable and worry-free. It was excellent value for money and highly recommended!
Zhu Zhu is a very caring tour leader. She introduced many attractions during the trip. Although the weather wasn't great when we went to Kusachisato, she managed the time very well when we went to Takachiho Gorge and we had a great time. Traveling with my mom also added some interest to her trip, making it a wonderful travel experience.
The customized itinerary was very convenient, and they also provided timely suggestions, helping to guide visitors to attractions and calling ahead to inquire about restaurant availability. Thank you, Ms. Liu, for your care over the past four days! And thank you to Mr. Shen for taking me to the airport on the last day.
