There was a shop that specialized in Jaos products in the Alhambra area in California years ago and there was some horrendously ugly stuff there.....like lowering kits for you Land Cruiser and spoilers and side skirts, etc....
I found some prices in yen. Wheel set with locks 259,200 = $2315.50. The 16" versions are $384 a wheel, and weigh about 20 lbs each. They are cast via the MAT process.
