In July 1969, a leak of chemical weapons on Okinawa sickened more than 20 U.S. soldiers and laid bare one of the Pentagon's biggest Cold War secrets: the storage of toxic munitions outside of the continental United States.

Public outrage following the Okinawa accident forced the White House to launch Operation Red Hat — codename for a mission to remove the chemicals from the island.

[For forty years, beginning with a desert test visible from the Sky Bar at Las Vegas’ Desert Inn, 928 nuclear devices were exploded at the Nevada test site, many of them above ground. In March 2005, the 8,000 square foot Atomic Testing Museum opened its doors near the Las Vegas strip. As Greg Mitchell records in the following piece, the museum is as notable for what goes unmentioned as for the events it depicts: these include the victims of the first atomic bombs dropped at Hiroshima and Nagasaki, and the plight of the “downwinders”, more than 12,000 of whom have filed claims in relationship to cancer and other illnesses that may be linked to the nuclear tests or uranium mining.]

New York In the weeks following the atomic attacks on Japan almost 60 years ago, and then for decades afterward, the United States engaged in airtight suppression of all film shot in Hiroshima and Nagasaki after the bombings. This included footage shot by U.S. military crews and Japanese newsreel teams. In addition, for many years all but a handful of newspaper photographs were seized or prohibited.

More than six months after dozens of rusty chemical barrels were unearthed from former U.S. military land in Okinawa City, their contents have been identified - and they appear to offer conclusive proof that the toxic Vietnam War defoliant Agent Orange was buried on the island.

Announced in early July, the results of two separate studies - one conducted by Okinawa City and one by the Okinawa Defense Bureau - both detected the three signature components of Agent Orange: the herbicides 2,4,5-T and 2,4-D as well as highly-toxic TCDD dioxin.

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 a Jacksonville Florida 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 witnessed it being sprayed at Kadena Air Base.

On 13 August 2004, a U.S. Marine Corps transport helicopter crashed onto the campus of Okinawa International University, Ginowan City, injuring the three service members on board and sparking a large fire. Although the accident occurred on civilian soil, U.S. forces cordoned off the scene and blocked access to Japanese police investigators; according to some reports the only local representatives allowed through the blockade were delivery drivers bringing pizzas to the American MPs. That night, the national Japanese TV news networks either failed to cover the crash or afforded it scant attention.

More than two years after the triple disasters that included the meltdowns at TEPCO's Fukushima Daiichi nuclear plant, between 160,000 and 300,000 Tohoku residents remain displaced, the power station teeters on the brink of further disaster, and large swathes of northern Japan are so irradiated they may be uninhabitable for generations to come. But today in Tokyo, it is as though March 11, 2011 never happened. The streets are packed with tourists and banners herald the city's 2020 Olympic bid; the neon lights are back on and all memories of post-meltdown power savings seem long forgotten.

Two leading Agent Orange specialists have weighed in on the recent discovery of 22 barrels buried on former military land in Okinawa City. Richard Clapp, professor emeritus at Boston University School of Public Health, and Wayne Dwernychuk, the scientist previously in charge of identifying defoliant contamination in southeast Asia, likened the levels of dioxin contamination in Okinawa City to dangerous hot-spots in Vietnam where the U.S. military had stored toxic defoliants during the 1960s and ‘70s.

To top it off last week, the Japanese Defense Minister threatened to fire live (albeit tracer) rounds on Chinese aircraft which continue to buzz the disputed Senkaku islands - 400 km west of Naha, the Okinawan capital.

It was against this drumbeat of resurgent Japanese militarism that more than 140 Okinawan civic representatives made a historic trip to Tokyo on Sunday. This was the first time since Okinawa reverted to Japanese control in 1972 that leaders from each of Okinawa's 41 municipalities have visited the nation's capital - and despite the bitter cold, they were met with a warm reception by 4000 Tokyoites at a rally in Hibiya Park.

The worst nuclear disaster to strike Japan since a single bomb fell over Nagasaki in 1945 occurred in the spring of 2011 at the Fukushima nuclear power plant following the epic tsunami. On August 22, The New York Times reports (in submerged fashion, headlining Gaddafi's imminent fall in Libya) the disturbing news that a wide area around the Fukushima plant “could soon be declared uninhabitable, perhaps for decades, after a government survey found radioactive contamination that far exceeded safe levels.”

In June 2013, construction workers unearthed more than 20 rusty barrels from beneath a soccer pitch in Okinawa City. The land had once been part of Kadena Air Base - the Pentagon's largest installation in the Pacific region - but was returned to civilian usage in 1987. Tests revealed that the barrels contained two ingredients of military defoliants used in the Vietnam War - the herbicide 2,4,5-T and 2,3,7,8-TCDD dioxin. Levels of the highly toxic TCDD in nearby water measured 280 times safe limits.

A former US soldier has identified a busy neighborhood in the Okinawa town of Chatan as the burial site of dozens of barrels of the toxic defoliant Agent Orange. The alleged burial took place in 1969 when the area was part of the US military's Hamby Air Field. Since its return to civilian use in 1981, it has been redeveloped into a sightseeing district with restaurants, hotels, apartment blocks and a popular beach.

There are dozens of brilliant war photographers, but there is only one Yoshito Matsushige.

For many years, Matsushige, 92, worked for a major metro daily called Chugoku Shimbun. He may not have been the greatest war photographer ever but he is unique: he took the only photographs in Hiroshima on Aug. 6, 1945, the day the first atomic bomb was detonated over the city, killing 150,000 people.

A single sentence buried among 7000 pages of documents recently released by the Pentagon might well be the needle in the haystack that conclusively proves the U.S. military stored toxic herbicides, including Agent Orange, on Okinawa during the Vietnam War. American veterans have long claimed that large volumes of these chemicals were present on the island and hundreds of them are suffering from serious illnesses they believe were triggered by their exposure. But the U.S. government has repeatedly denied their allegations, insisting it has no records related to the issue.

One afternoon in the mid-1980s, Kimura Hiroko was taking a rest from sightseeing on a park bench in Adelaide, southern Australia. As she was enjoying the warm sunshine, she spotted the words “Japs go home” carved into the wood. This was the height of the bubble years and Kimura was aware that some people resented Japanese companies buying up Australian land, but she hadn't known the hatred ran this deep. “From that moment on,” she says, “I made up my mind to do something to bring together Australian and Japanese people.”
