FWIW, for JIS screws with the cross-slot drive, I have a set of Vessel JIS drivers. I got mine from McMaster-Carr. If folks are dealing with many of these fasteners, I recommend getting the specific screw driver.
Some of the smaller screws (m5 and M6) screws I buy from US suppliers come with the JIS cross, often indicated by a little dot on the fasteners.
