NAHA, Okinawa Pref. — A Japanese man with the unusual background of having served in the U.S. Marine Corps is using his experience to vigorously campaign against the U.S. military presence in Okinawa.

Kimitoshi Takanashi, 38, joined the marines in his 20s and once served in Okinawa during his four-year career in the U.S. military.

The sharp-eyed man, sporting a Mohawk hairdo, has a muscular build that hardly looks like the body of a man nearing 40. On his right arm are tattooed the words, "KILL 'EM ALL."
