You are asking about Type 74 kai, it is officially Type 74(G). It means there are seven types of Type 74 in service though it looks very similar.
Type 74(G), sometime called Type 74 Kai completed one in 1993 as a experimental type, four was formally remodelled in 1994.
Main features of improvements are equipped with a passive infrared camera, laser detection device, the track secession prevention ring and the side skirt are able to equip. However side skirt was equipped only with an experimental type by limiting the budget.
