Does anyone know an english speaking site that sells Yashio Factory products to people in the US. *more than one or two products, hopefully most of them. Any help would be appreciated.

Googling came up with
http://www.bulletproofautomotive.com/manufacturers.php and http://www.underground-motorsports.com/catalog-manufacturers.htm
as dealers.

Go to raretrick.com or thejdmstore.com. They carry a fair selection of yashio factory parts.
