A questionnaire survey on recycled products qualification program organized by prefectural governments in Japan and follow-up studies based on the official websites of each program were conducted to gain an understanding of the actual situation. Our results show that, of 47 prefectural governments in Japan, 35 have implemented the program, and 4,000+ products have already been qualified. Of all, four types of qualified products, namely precast concrete, crushed rock, paving and asphalt, accounted for the half of total numbers. The questionnaire survey revealed that a total of 4.2 million ton of qualified products has been sold, and about 13 billion yen has been spent for procuring a total of 5.5 million ton of products. The amount of recyclable resources used in qualified products was estimated as >12 million ton/year in the 35 prefectures surveyed.
