Driving in Japan as a tourist – experience / requirements?

Hi everyone, I’m from Germany and I have a German driver’s license. I’m planning to drive in Japan as a tourist and I’m curious about your experience.

Did you drive in Japan as a tourist?

What documents did you need?

Did you get a Japanese translation of your license beforehand or on-site?

How much did it cost?

Any tips or experiences would be super helpful! Thanks a lot.
