Our driver, Kai, was excellent. He arrived at the meeting point more than half an hour early and thoughtfully turned on the air conditioning. His explanations of the attractions and important information, including the meeting points, were always very detailed and clear, and his attitude was outstanding. On the way back to Tokyo, he kept a close eye on the road conditions, ensuring a smooth return. If any guests couldn't find their way, he immediately went to look for them with great patience.
