The Eco-Airport Initiatives have been implemented not only in Japan but in other countries in a parallel fashion. In this paper, two examples are given, the first one is the environmental protection measures taken by the Japanese companies for the construction of New Bohol Airport in the Philippines. The second one is the benefits of using photocatalytic coatings at Terminal 2 of Noi Bai International Airport in Viet Nam. These two examples epitomize the effectiveness of the Eco-Airport Initiatives taken by Japan. Moreover, the collaboration between ASEAN Member States and Japan on the Eco-Airport Initiatives is presented.
