Will the Hori EX2 bought in Japan work on EU 360's?

It might be a stupid question, it might not be. I told my friend he should pick up a stick while he is in Japan because it’s hard to get hold of a new Hori in the UK atm.

He was told by one of the staff at whatever shop he was in that the EX2 bought in Japan wouldn’t work on an EU console. Is there any truth to this?

I gave the search a try but didn’t find what I was looking for.

A stick bought in Japan WILL work on an EU console. Peripherals are always region free.

I’m using a locally bought SFIV SE on a Japanese console, for example.
