It's quite good!

Smooth communication. The car rental company sent reminders about the pickup time via email and messaging apps a day before. Upon arrival at the airport's multilevel parking garage and contacting them, it only took five minutes to get the car. Child seats and ETC cards require cash payment. The ETC card deposit is 30,000 yen, with adjustments made during the return based on usage.

I often go on self-driving trips, and this was by far the best experience. Especially the driver who handled the shuttle—he was so communicative, highly experienced, and had a great attitude. He even explained how to use the car and helped connect the Bluetooth during the process. This was the best self-driving experience I've had globally.

Very satisfied.

They need to ensure rental cars are regularly serviced and is actually drivable.

First time booking, overall experience was straightforward. Shall see if diamond membership is really worth it with my next booking.
