All of the Shimano lures I have seen come from Japan. I have a couple and that's where I got them from.
Look at e-bay user id sayaka603. He sells a lot of Shimano lures. They're nothing special for the price. Once you pay shipping you could have just bought a LuckyCraft. There are some old Shimano lures too. I think they were bagley/shimano? I can't remember :(
