Everything is good

Pickup and return were very fast, completed within 5-10 minutes.

Although I booked through Europcar, in Japan it was actually Times. The booking reference didn't match. Eventually, we asked at the airport information desk and compared phone numbers from different car rental companies to find out it was Times and got the specific store location. Otherwise, we would have had to call the store, but our phone cards were for internet use only and couldn't make calls, which made it more troublesome.

Car very good, but seats uncomfortable.

We had issues with our IDP which wasn't dated (error by Post Office in the UK) but it took an hour to convince Europcar/Times to accept it was valid. Otherwise the Times staff were helpful and the return drop off details very good.

Easy to book the car and one way hire options better than competitors- but hire overall was expensive vs other countries. Plus cost of tolls was not pointed out upfront.
