Question: Who attacked the United Nation's forces in Okinawa as a part of Operation Ten-Go.
Context: Yamato (男たちの大和 , "Otoko-tachi no Yamato" , literally "The Men's Yamato") is a 2005 Japanese war film.  It was directed by Junya Satō and is based on a book by Jun Henmi.  With a framing story set in the present day, by flashbacks it tells the story of the crew of the World War II Japanese battleship "Yamato", concentrating on the ship's demise during Operation Ten-Go. Operation Ten-Go (天號作戰 (Kyūjitai) or (Shinjitai) , Ten-gō Sakusen ) was a Japanese naval operation plan in 1945, consisting of four likely scenarios.  Its first scenario, Operation Heaven One (or Ten-ichi-gō天一号) became the last major Japanese naval operation in the Pacific Theater of World War II.  The resulting engagement is also known as the Battle of the East China Sea. Operation Kikusui (菊水作戦 , Kikusui sakusen ) was a series of suicidal air attacks by Imperial Japanese forces during the Battle of Okinawa against Allied fleets in the waters around Okinawa, as part of Operation Ten-Go.  The name of the operation, "Kikusui", comes from the hata-jirushi of the samurai Kusunoki Masashige. The United Nations Peacekeepers Medal (Irish: "An Bonn Chosantóirí Siochána na Náisiún Aontaithe" ) is awarded to those members of the Irish Defence Forces or Chaplaincy Service who have served overseas on a United Nation Mission or United Nations Mandated Mission. The Special Action Committee on Okinawa (SACO 沖縄に関する特別行動委員会 (Okinawa ni kansuru tokubetsu kōdō iinkai ) ) is a formal agreement made between the United States Government and the Government of Japan.  The U.S. and the Japanese government established the SACO agreement on November 1995.  About 75% of land area of exclusive-use U.S. military installations in Japan exist on the island of Okinawa.  The Agreement was brought on by a political uprising that escalated when an Okinawan schoolgirl was abducted and raped by three U.S. servicemen in September 1995.  The agreement's purpose was to reduce the impact of the U.S. military presence on the people of Okinawa.  The SACO developed recommendations to realign, consolidate, and reduce U.S. facilities and adjust operational procedures.  In December 1996, the United States agreed to return 21% (about 12000 acre ) of the land in Okinawa from 11 U.S. military installations.  The final report of the SACO outlines the requirements of returning land, adjusting training and operational procedures, implementing noise abatement procedures, and changing the Status of Forces Agreement (SOFA) procedures. The Allies of World War II, called the United Nations from the 1 January 1942 declaration, were the countries that together opposed the Axis powers during the Second World War (1939–1945).  The Allies promoted the alliance as seeking to stop German, Japanese and Italian aggression. Mitsuru Yoshida (吉田 満 "Yoshida Mitsuru" January 6, 1923 – September 17, 1979) was a Japanese author and naval officer.  He was born in Tokyo.  He was a survivor of the battleship "Yamato" when it was sunk on 7 April 1945 during Operation Ten-Go, an attempt to support the defenders of Okinawa. Asashimo (朝霜 , "Morning Frost") was a "Yūgumo"-class destroyer of the Imperial Japanese Navy.  She was among the several ships sunk during Operation Ten-Go by attacking US aircraft in 1945. The Battle of Okinawa (Japanese: 沖縄戦 , Hepburn: Okinawa-sen ) (Okinawan: 沖縄戦 , "Uchinaa ikusa " ), codenamed Operation Iceberg, was a major battle of the Pacific War fought on the island of Okinawa by United States Marine and Army forces against the Imperial Japanese Army and included the largest amphibious assault in the Pacific War during World War II, the April 1, 1945, invasion of Okinawa itself.  The 82-day battle lasted from April 1 until June 22, 1945.  After a long campaign of island hopping, the Allies were planning to use Okinawa, a large island only 340 mi away from mainland Japan, as a base for air operations for the planned invasion of the Japanese home islands.
