It was a great experience. We easily found the meeting point at Hakata Station. Our guide, Nanami, was incredibly friendly and effortlessly switched between Chinese, Japanese, and English, explaining the itinerary and providing brief details about the attractions. The mini-bus was also very comfortable, and the driver was skilled. If you have luggage, you need to contact them via email in advance. We were lucky today; although it was cloudy with scattered showers, it didn't rain during our visits to the attractions, even though it rained heavily on the road. The turbulent sea and the vibrant red torii gate offered a wonderful experience. Akiyoshido Cave was quite cool inside, so bringing a jacket is recommended; it felt like a cave exploration. The crepes at the ice cream shop by the cave entrance were mediocre and not cheap.
