OSAKIKAMIJIMA, Japan -- On a small island in western Japan's Hiroshima prefecture, reachable only by a 30-minute ferry ride from the mainland, a decadelong attempt to prove coal can be made "clean" is drawing to an end -- though its accomplishments face a murky future.
A 118,000-square-meter jungle of tanks, chimneys and pipes spreads out against the sparkling Seto Inland Sea and green mountains. Visitors are largely prohibited from taking photos for fear of leaking Japan's front-line technologies.
