Designing sampling strategy is a major concern in statistics. The same also holds for study fields that discuss spatial data modeling, including geostatistics; and, recently, sample site selection design is intensively discussed in these fields. This study applies geostatistics to the assessed site allocation problem in the officially assessed land price data and prefectural land price data in Japan. Firstly, we explain these land price data, while mainly focusing on basic rules of their assessed site allocation. Then, studies discussing sampling design problems are briefly summarized. Subsequently, points, which we must consider, are clarified, and geostatistical approaches for the land price assessed site allocation problem are developed based on the points. Finally, the developed approaches are used to the assessed site reduction problem in Ibaraki prefecture, and their effectiveness is examined.
