Thousands of barrels of Agent Orange were unloaded on Okinawa Island and stored at the port of Naha, and at the U.S. military's Kadena and Camp Schwab bases between 1965 and 1966, an American veteran who served in Okinawa claims.

In an interview in early April with The Japan Times and Ryukyu Asahi Broadcasting Co., a TV network based in Okinawa, former infantryman Larry Carlson, 67, also said that Okinawan stevedores were exposed to the highly toxic herbicide as they labored in the holds of ships, and that he even saw it being sprayed at Kadena Air Base.

Carlson is one of only three American servicemen who have won benefits from the U.S. government over exposure to the toxic defoliant on Okinawa — and the first of them to step forward and reveal that massive amounts of it were kept on the island.
