Tougo, Denkuro

An Advenna Avis immortal. After landing in America in 1711 he attempts to walk back to Japan but ends up buried in ice somewhere around the North Pole. He is eventually found by a Soviet nuclear submarine and ends up going on the run from the KGB for most of the Cold War. He finally makes it back to Japan sometime in the early 1990's.
