Train trips mostly fit Japan better, and it's more relaxing.

Kyoto is an amazing place, Tokyo is a must, and Mount Fuji is quite nice. I've heard Osaka is cool, but I've never been. Beyond that, specifics depend on what you're into.

My favorite bits were generally the food, temples, museums, onsen and just wandering around shopping districts and taking it all in.

Also, Japan has fairly high road tolls, so driving adds up fast. And there's not really free street parking either.

Travelling by train kinda becomes boring after a while, hence I'll go for a car next time.
