There are four striking areas in kendo:

KOTE is a strike to the opponents right wrist. A strike to the left wrist is allowed only in curtain techniques.

MEN is a strike to the top of the head. Strikes to either side of the head are also allowed.

DO is generally a strike to the right side of the opponents abdomen. A strike to the left side is allowed only in curtain techniques and is harder to score a point.

TSUKI is a thrust to the throat. Since it is a technique that requires a high degree of accuracy and speed it is used only by Yudansha (black belts).

In kendo simply striking a target is not automatically a point. Points are given based on intent of the strike, its perfection, follow through and unity of mind and body at the time of striking. For this reason it takes years of practicing to perfect striking the four target areas.
