I was looking for interesting examples of successful letter writing campaigns and found this story from last month (I'm kind of surprised I missed this when it was in the news cycle).
Japan has rechristened the island of Iwo Jima, site of one of World War II's most horrific battles, with its pre-war name in an attempt to rectify a misnomer proliferated for a half-century by such movies as Clint Eastwood's "Letters from Iwo Jima."...
The change was championed by surviving islanders evacuated during the war, who wanted to reclaim an identity they said had been hijacked.
American maps will not rename the island.
