Dear komti_2000,
try to change the keyboard properties on the control panel and update yourkeyboard lay out to suit your need by select the right keyboard lay out. (English 102/103keys) or (Japanese 106/109keys) and please select the regional and language setting to suit with your computer maker. (i.e: if you computer made in japan, so the keyboard layout MUST be the 106/109keys keyboard).

GoodLuck!
