This week's Tokyo International Anime Fair offers overseas buyers an opportunity to choose from among a vast array of Japanese anime to purchase for use in their home markets. The producers of the films, of course, are just as eager to connect with customers from abroad. A declining birthrate and slow economy have dampened domestic sales. Japanese producers also are working to stay a step ahead of filmmakers from around the world who hope to compete with anime of their own. In this climate, JETRO--the government-affiliated Japan External Trade Organization--is offering assistance to Japanese companies in finding potential business partners from the US, Europe, and China.
