JIS threads are metric so the left side covers them. They just have different head sizes in some cases but that board is only about threads.

Thank you. For some reason I was thinking the thread pitch was different.

I do remember reading that some JIS threads were different from the standard ISO, but that may well be a feature of older JIS fasteners and not newer ones, I'm not sure.

JIS hardware tends to use a finer thread pitch in some sizes than normal ISO metric hardware, though it will still be on that board. M6x1.0, M8x1.25, M10x1.25, and M12x1.25.
