Yeah Guitar Japan is good, but go to any guitar store in Japan's main areas....DAMN...it is heaven.
like they have every guitar by their brands, not just the popular ones. Saw guitars I've only seen pictures of...worried I was droolin on their stuff...but unfortunitly, being a kid, they don't like lettin me play stuff, they kinda kicked me out of the ishibashi store for tryin a Jaguar...So if you old enough go ahead.
ADD: plus the amp room was good too, Oranges(never seen in by me) were plentiful, along with every other dream head I can think of.
