booked an airport transfer from kansai airport to Shirahama, a 2 hour plus drive away so was worried won't be able to find a car charter. The company was super responsive with enquiries, confirmed with me 1 week before the date and driver also contacted me in advance. Very easy communication, driver came early to wait for us, was very polite and helpful, and had a very smooth drive. Highly recommend
Arrangement was easy and smooth, driver is very professional and gave clear instructions where to wait for him. I did not top up for name placard service. The provided car was clean and well maintained. Highly recommended for this service especially when travelling with small kid.
Upon arrival, it was confirmed that the cable car was operating normally, and I could immediately purchase a ticket and use it – very convenient. Those concerned about the weather can follow the same procedure. Definitely worth visiting during the fall foliage season.
