Hello, welcome!

Loved the car scene when I was over in Japan, laughed at the way you guys modify those little Nissan cubes haha

Where about do you board? I've been to Niseko, stayed at the Hilton, too many westerner a for my liking, I preferred being in the midst of it, Kyoto and Osaka were very nice, Roppongi was pretty awesome too!

Hopefully you can get some good information on what is needed

Post up some pics of your car while you're at it!
