Common marking on OEM and aftermarket wheels?

Anyone know what this mark means? It seems like all Toyota alloy wheels have the marking, but some aftermarket wheels, and domestic cars have the same mark. What does it mean?

JWL = Japan Light Wheel Alloy

Thanks, So its like having a UL listing for wheels. This link explains it best.

"JWL" (Japan Light Wheel Alloy) is a compilation of standards defined by the Japanese Government to ensure the vehicle's safety for aluminum road wheels. Every wheel put to market must be tested to meet JWL standards before a wheel can be put out to market in Japan.

These standards are generally accepted worldwide as acceptable for most road conditions. That is why you will see these marks on European and other Asian country wheels.

yep, basically.

be wary though, a LOT of knock off/cheaper wheels have the markings but have NOT been certified by the JWL.

This again. It's simply not true, there is not a massive market of these "knockoff" wheels like there are other items simply because making a wheel is difficult.
