I booked airport transfer through KK Day again, and the service quality was still excellent. The driver was punctual, and the customer service staff answered my questions in a friendly manner.
I experienced Ainu culture up close for the first time. I was deeply impressed by learning about the spiritual culture of the Ainu people. The traditional dances, clothing, and tools were all incredibly impressive. The fact that Ainu is the official language within the facility also made it a truly precious experience. I highly recommend this tour.
My two daughters, my sister, and I went stand-up paddleboarding (SUP) for the first time. Unfortunately, the weather was rainy, but the instructor was very entertaining and taught us clearly and patiently, even though we were beginners. We received lots of photos and videos, making it a wonderful memory. We would definitely like to do it again!
