I live in Tokyo, and I have no idea why your girlfriend is telling you that the monitor is built into the PC in all computers in Japan (if that's what she's telling you). That is not true at all. In all the offices I have worked in here we had standard desktop PCs with a separate monitor, same as you would find in any other country, and it's the same in internet cafes.

Yes, Japanese people call laptops notebooks or note PCs.
