Not Japanese, Chinese. The very first run of guitars were Japanese...but everything since has been Chinese.
As a guy who works in a music store that's an authorized Gibson repair station and having also owned dozens of Gibsons myself, an Edwards is in absolutely no way comparable to a Les Paul. If you're closing your eyes and thinking it's just as good...well I'm happy for you. At the same time though, I can't help but question your perception of quality.

My old Edwards.
No contest
The ESP Edwards brand guitars are products made solely for the Japanese market. The difference between Edwards and ESP is that Edwards' guitars are produced in different factories in Japan, and are generally considered to be of almost equal quality to the ESP Originals, but the fundamental difference being the hardware, especially in the case of tonewoods, for example FR-130GT uses a Maple neck and ash wings while the Original series Forest GT uses a mahogany neck and wings, but with a White ash top, however the hardware such as pickups, tuners, tremolo etc, are almost identical. In many cases, Edwards' guitars are built from more expensive materials than their Ltd counterparts and on a superior production line in Japan as opposed to LTD's Korea. Although these guitars are officially only available to the Japanese market, they are frequently seen on auction sites such as eBay. Edwards guitars are now licensed for distribution in Russia.
Since 2009 a wide range of Edwards' guitars are available for export[
Wiki isn't totally reliable, but the one I had was a Jap and it played really nice. Perception is a great thing and since the newer Gibsons are the best guitars ever, then it'd be an easy comparison to make.
