There seems to be a new crop of keyboard by the usual crap maker (Elecom and co).
They appear to be US keyboards as they lack any kana printed on the keys as the spacebar is of a good width. But if you look closely you will see the script switching key is present and all the !@#$%^&*()_+|{}:" keys are on the japanese position, not the US one.
