Hello,
my friend has windows on his computer he bought here in japan, can he reinstall windows in another language using the same product key that came with his machine?

You don't need to re-install, just install the appropriate language pack.

To install a fresh copy from scratch, you will need to have the oem version, they key should work fine.
