It says Made in Japan. It's heavy and matte black. Can't post the pic due to size limitations.
Yes, you can restore it.
Clean the whole wok. Wash with soap and dry it. Apply a small coat of oil and put it on high. Let it burn (ventilate the kitchen).
Repeat the process of applying a small coat of oil and putting it on high another two or three times.
Edit: As noted by @GdD, this method cannot be applied to non-stick woks.
Given the cost of most asian wok, it would be more cost effective to purchase a new one than restoring a damaged wok. Assuming it's not-non-stick or not-coated, you can season the wok as if it's a carbon steel or cast iron pan. Scrub off the rust in hot water until water is clear; then best with non processed oil like animal fat or lard frying with onion and perhaps some salt under high heat until the wok turns dark.
