April 1, 2017 marked the seventy-second anniversary of the start of the Battle of Okinawa, when American forces landed on the island of Okinawa during World War II. The nearly 290,000 American soldiers who took part in the invasion of Okinawa were opposed by 150,000 Japanese troops. This was the first and only time American soldiers fought on Japanese soil. More than 20,000 Americans [2] would be killed during the Battle of Okinawa, while the Japanese military dead would top more than 100,000 [3]. During the battle it's estimated 150,000 Okinawa civilians [4], out of a pre-invasion population of 300,000, were also killed by both Japanese and US forces.

Okinawa would be administered by the United States until 1972. The island served as a major American base during the Vietnam war, and the American presence in Okinawa continues to this day. Of Okinawa's 1.4 million residents, more than 100,000 are Americans [5]mostly military personnel and their dependents [6] or Department of Defense civilian employees.

On the seventy-second anniversary of the Battle of Okinawa, Japanese researcher Hidenori Watanave has made a variety of Twitter posts that feature archival photos of the battle that have been colorized using a software tool [7] created by researchers at Japan's Waseda University. Watanave has spearheaded many innovative online mapping projects, including mapping the oral history [8] of the Japanese attack on Pearl Harbor [9] on December 7, and an interactive map of the Hiroshima [10] and Nagasaki [11] atomic bombings.

Many of colorized photos of the Battle of Okinawa Watanave has posted on his Twitter feed are from the Okinawa Digital Archive [1], an online mapping project that, like Watanave's other projects, places photos and eyewitness testimony on a map.

In the case of the Battle of Okinawa, Watanave tweeted photos on the date on which they were taken 72 years ago.

The photos provide a concrete perspective on what was happening during Battle of Okinawa.

72 years ago today – Kakazu Ridge, in an image taken on April 9, 1945. Kakazu Ridge would mark the start of the fiercest fighting of the Battle of Okinawa, where at least 64,000 Japanese troops would die and 24,000 Americans.

Watanave has also colorized some spectacular photos, such as the sinking of the battleship Yamato, at the time the largest ship ever constructed [23].

Watanave's Twitter feed also features colorized photos of the aftermath of the war.

The Battle of Okinawa also saw civilians experiencing great cruelty at the hands of American and Japanese forces. Watanave's Okinawa Digital Archive documents such civilians experiences of the battle and can be explored at okinawa.mapping.jp [1]. The book Descent into Hell: Civilian Memories of the Battle of Okinawa [30] by Okinawa’s Ryukyu Shimpo newspaper is also a good resource for these stories.

Explore testimonies, photographs and just where people died during the Battle of Okinawa. American forces landed seventy-two years ago today (April 1, 2017), so please take a look.
