We developed new guidelines for aggregating land-use classifications based on the classification of a 1:25,000 national vegetation map archived by the Ministry of the Environment. We also show the correspondence between the new guidelines and previous guidelines based on a 1:50,000 vegetation map. The guidelines based on the 1:25,000 vegetation map for large (nine classes) and intermediate (16 classes) classifications are the same as the previous guidelines based on the 1:50,000 vegetation map, so the new land-use map can be used as time series data with the previous land-use map. For the fine classification, there are eight new classes and three modified classes related to deer herbivory and alien species.
