'Law on Promoting Proper Management and Use of Livestock Manure' was established in 1999 and implemented in 2004 in Japan in order to decrease pollution caused by livestock manure. After the implementation of this law many composting facilities have been established rapidly. However, it is not clarified how the distribution of compost has been changed by the implementation of this law. Therefore, in this paper, the change of the distribution of compost between 1995 and 2005 is estimated by the statistical analysis about supply and demand balance of livestock manure in village level in Hyogo prefecture, which is famous for promoting livestock industry. The result of this estimation shows that the recycling rate has increased from 39% to 58% in Hyogo prefecture. However, the increase of recycling rate is only from 23% to 39% in Awaji area, which is specialized for livestock industry. This implies that a lot of livestock manure is over-applied to farmland in this area. Consequently further political approaches are considered to be necessary to correct the oversupply of livestock manure.
