Overall service was satisfactory, but the only drawback was the shuttle bus after returning the car dropped us off at the domestic terminal, which required a long walk. The driver clearly knew we were international tourists and could have dropped us off at the international terminal but didn't even ask, which felt somewhat intentional. By the way, our family of four were the only passengers in the vehicle.

The service was excellent.

Everything was good except they wouldn't lend me an ETC card.

After completing the car rental formalities at Narita Airport Terminal 2, we waited for almost half an hour before a vehicle was sent to take us to the nearby branch to collect the car. It turns out they wait for a group of renters to complete their paperwork before dispatching the shuttle. I recommend keeping this in mind when planning your schedule.

pre book the etc card as it will be hard to get at the counter
