The Japanese government's attempts to reduce fine particles (PM2.5) emission pollution in Japan have been largely ineffective. This is because PM2.5 in Japan originated from various sources including around half from oversea countries such as China. This prompts the Japanese government to start a new initiative to reduce PM2.5 at its origin by transferring local knowledge on air pollution reduction measures and technologies to China and working closely with the Chinese government. To promote further reduction in PM2.5, bilateral corporation between Japan and China should be extended to include Korea. It is recommended that an international convention should be in place to deal with transboundary air pollutants in East Asia. A successful East Asia corporation to reduce PM2.5 will not only contribute to clean air but also to future sustainable low carbon society in this region.
