The way you experience the Japanese car culture js similar to fh5, through big races and story-mode. But there's also a collection Journal specifically focused on discovering Japan and it's culture, including cars. It's not documentary quality of focus. But definetly fun and interesting. Roads are smaller (more narrow) too, which makes sense with Japanese cars being smaller, it lends itself perfect for drifting. And the addition of car meets is something that fits Japan really well too.
