Present Status of Cadastral Survey
Cadastral Survey has been conducted since 1951 when National Land Survey Law was established.
Looking at the progress rate of each prefecture, we can see variation from region to region.
Progress rate:acreage of survey – completed area / acreage of survey – required area × 100(%)
Details of Progress Rate
The acreage of survey-required area is the each prefecture’s area excluding the national forest and all the lakes, ponds and rivers etc.
Excluding survey-executed area, there are some cases that the survey product from land adjustment etc. is kept at registry office. But the most half of its map is not able to restore the status.
