I have a Husky (Home Depot brand) 1/2" air impact gun.
It's made in Japan. Its been great. I do not use it much, but it has never failed me and I'd buy it again. I purchased mine years ago. It was cheaper, but I do not remember the exact cost. I wonder if they are still made in Japan.

I also have a few other air tools from Japan. I believe one is a Matco. Not 100% on that though. Its older, 10 years + possibly. Its also been an excellent tool.
