JIS? (Japanese industrial standard).
JIS screwheads are usually marked with a dimple/punch mark or an 'x'.
It's definitely worth having a couple of JIS screwdrivers in your toolbox. If you're used to struggling with Phillips/Pozi drivers on JIS screws, the first time you use the JIS driver is a revelation!
