大矢 英代(Hanayo Oya)







Reporting for Justice.
Holding Military and State Power Accountable.

Hanayo Oya has engaged in journalism for eight years as her professional career. Her core value is a commitment to using my camera and words to hold power accountable and protect the rights of underrepresented people in society.

In 2012, after completing a master's degree at Journalism School, Hanayo started her reporter career at a TV station in Okinawa, Japan. She has been widely known for her coverage of the U.S. military in local communities, especially crimes committed by military personnel. Her reports and documentary programs have received six awards of excellence.

Hanayo became freelance in 2017, producing her first documentary film “Boy Soldiers: The Secret War in Okinawa.” It exposed the Japanese military’s crimes against civilians during the Battle of Okinawa, revealing covert missions of graduates from the secret Imperial Japanese Army Nakano School.

The film has been shown in Japanese theaters to a total of 30,000 audiences, as well as at international film festivals such as South Korea, Germany, and Switzerland. It has received nine awards of excellence, including Award for Best Documentary Film from the Kinema Junpo Award for Best Film of the Year 2018, Japan’s most prestigious film award. Most recently, it received the Excellent Film award from the Agency for Cultural Affairs and the Japanese Ministry of Education, Culture, Sports, Science, and Technology.

In 2018, Hanayo received a Fulbright Scholarship and became a visiting scholar at the University of California, Berkeley. She has been researching how the U.S. Status of Forces Agreement has affected the criminal jurisdiction of host countries in East Asia and Europe. To promote this project, she started an affiliation with the Center for Japanese Studies at UC Berkeley.

In February 2020, Hanayo published her first non-fiction book "Okinawa War Malaria: revealing the truth of the death of 3,600 civilians and the enforced relocation" (Japanese). It was about a hidden story of the Battle of Okinawa in 1945, in which the Japanese Army enforced local people in Yaeyama islands to relocated to Malaria contaminated mountain areas. As a consequence, more than 3,600 civilians died from a Malaria infection. This incident has been called "War Malaria" as their deaths were brought not from direct battles but the order by the Japanese Army. Through 10 years of researching on "War Malaria", Hanayo revealed a true reason behind the enforced relocation and voices of the victims for the first time after 75 years since the end of the Battle of Okinawa. 

In May 2020, Hanayo won the 7th Mika Yamamoto Memorial International Journalist Encouragement Award with the book. This award is to be presented to a journalist who contributes to covering honest and bold international reporting in honor of the spirit of Mika Yamamoto, a female Japanese journalist killed while reporting the ongoing civil war in Aleppo, Syria in 2012.

During World War II, Japan sacrificed a large number of civilians, due to the actions of a militarist and nationalist government. Therefore, Hanayo believes it is a crucial mission for journalists to act as a watchdog, especially toward military power, to prevent a similar tragedy. she believes that through their reporting, journalists should empower people to question government and military policies.
