Just because it says Made in Japan doesn't actually mean it was. Less than reputable Chinese manufacturers will slap just about anything on their product to try and sell it.

The fact that there's so little text tells me it's not. Never mind that the string of kanji there is Chinese, and it has no manufacturer label at all.

I also love that the packaging has ORIGINAL printed on it twice, as if to reassure you it isn't a nameless, cheap knockoff. Buying that is about as trustworthy as buying thumb drives and SD cards off eBay.
