I would have to say though, looking at the signature on your plate, it looks like it's a poorly imitated writer who doesn't actually know how to write Chinese (or at least Kanji, which although still "Japanese" but in Chinese words). You can refer to the link provided above where your plate maker was trying to imitate from, the most obvious being the last word "造" meaning "made" - what's on the plate looks nothing like it
