The tour guide was excellent; we were the only two foreigners in the group. He took great care of us, patiently communicating with us using translation software even though we didn't speak Japanese or English. The driver was also very nice, and the tour bus was brand new! It was a fantastic trip, and I highly recommend it.
The driver's English was fluent, and he was very familiar with the routes, offering many suggestions for us to choose from. He was very attentive and considerate in every detail along the way, making the entire trip very pleasant. It was the best experience we've had with a private car hire in Japan. The customer service team was also very clear in their communication and provided timely assistance. We are very grateful.
