Protection of tideland in Isahaya Bay, Nagasaki Prefecture, has been given added momentum now that the world's environmentalists have offered their full support, according to a hardcore Isahaya tideland activist and winner of a renowned U.S. environmental prize.

Hirofumi Yamashita, 64, head of the Japan Wetland Action Network, a local citizens' group, received the Goldman Environmental Prize on April 20 in San Francisco for his 27-year battle to preserve ecological diversity on the Isahaya tidal flat.
