Was the destroyer "Isokaze" that was sunk together with the battleship "Yamato" found?

Recently the NHK News On-line reported the following:
戦艦「大和」とともに沈んだ駆逐艦「磯風」発見か
27 2338

太平洋戦争末期、戦艦「大和」とともに沖縄に向かいアメリカ軍の攻撃によって沈んだ旧日本海軍の駆逐艦「磯風」と見られる艦船が鹿児島県沖の海底で見つかっていたことがわかりました。専門家は、大和以外の艦船の調査は行われておらず、貴重な発見だと評価しています。

駆逐艦「磯風」は昭和15年に就役して真珠湾攻撃やミッドウェー海戦などに参加しましたが、戦艦大和とともに特攻作戦で沖縄に向かっていた昭和20年4月7日、鹿児島県の枕崎沖でアメリカ軍の攻撃によって沈みました。

大和について広島県呉市とともに潜水調査を行った大阪市の海洋調査会社によりますと、おととし5月の調査の中で、大和が沈んだ場所から北東に9.5キロ、深さおよそ450メートルの海底で、艦船1隻が沈んでいるのが見つかったということです。

これについて専門家は、撮影された映像や戦闘の記録などから「磯風」の可能性が高いとしています。

映像には4つの砲身をもつ魚雷発射管のほか、爆発でめくれ上がった艦尾や横倒しになった主砲も映し出されていて、当時の戦闘の激しさがうかがえます。

旧日本海軍の歴史に詳しい広島県呉市の大和ミュージアムの戸高一成館長は、「記録に残る被害状況や沈没場所をつきあわせると磯風でほぼ間違いない。大和以外の艦船の調査は行われておらず貴重な発見だ」と話しています。

磯風は数多くの作戦に参加
旧日本海軍の駆逐艦「磯風」は、長崎県佐世保市の旧海軍工廠で建造され昭和15年に就役しました。全長はおよそ120メートル、基準排水量は2000トン余りです。

広島県呉市の博物館「大和ミュージアム」によりますと、磯風は、真珠湾攻撃をはじめミッドウェー海戦やレイテ沖海戦など旧日本海軍の数多くの作戦に参加しました。

昭和20年4月、戦艦「大和」など、ほかの9隻とともに特攻作戦で沖縄に向かいましたが、アメリカ軍の攻撃によって大和や磯風を含む6隻が鹿児島県枕崎沖で沈みました。

大和は戦後、呉市や民間団体が潜水調査を行ったため沈没した位置が判明していますが、磯風など5隻については、沈没した場所は特定されてきませんでした。今回、大和以外の艦船の沈没位置がわかったのは、初めてだということです。

磯風の調査にあたった「深田サルベージ建設」の花戸忠明中国支社長補佐は、「磯風以外にも見つかっていない艦船があるので可能であれば調査したい」と話しています。

My translation

It was found out that during the last years of the Pacific War the destroyer "Isokaze” of the old Japanese navy which was sunk together with the battleship "Yamato" by the offensive of the U.S. forces that moved towards Okinawa were discovered at the bottom of the sea off the coast of Kagoshima prefecture. As ships besides Yamato had not been investigated so far, a specialist estimated that it was a valuable discovery.

Destroyer "Isokaze" was commissioned in 1940 and had participated in the Pearl Harbor attack and the Battle of Midway, but was sunk by the U.S offensive forces at the Makurazaki offing at Kagoshima-ken on April 7, 1945 together with  the battleship Yamato while  going to Okinawa on a special attack operation.

Regarding Yamato, according to Kure-shi of Hiroshima and also one oceanographic investigation company from Osaka-shi that did a diving  investigation, it was said that in the investigation in May two years ago one ship was found sunk at the bottom of the sea at depth of 450 meters at about 9.5 km northeast from the place where Yamato was sunk.

About this, based on the photos taken and records of the battle, specialists assumed that there was a high possibility it was the "Isokaze".

In addition to a torpedo launching tube with 4 tubes, the stern that got curled up by an explosion, and the main gun that was lying down were also projected in the picture, all these told about the violence of the battle in those days.

Todaka Kazushige the director of Yamato museum in Kure-shi of Hiroshima who was conversant with history of the old Japan Navy said that "When compared with the damage as put down on the record and also the sinking location, most apparent it is the Isokaze. Ships besides Yamato have not been investigated, it is a valuable discovery."

Isokaze had participated in a large number of battles
As a destroyer of the old Japanese Navy "Isokaze" was built at an old dockyard in Sasebo-shi, Nagasaki, and went into commission in 1940. The full length was approximately 120 meters and the standard displacement was about 2000 tons.

According to the "Yamato Museum" in Kure-shi of Hiroshima, Isokaze had participated in a large number of battles in the old Japanese Navy starting with the Pearl Harbor attack, then the Battle of Midway and the naval battle at Leyte offing.

In April, 1945 nine ships including the battleship "Yamato" moved towards Okinawa for a special operation, but 6 ships including Yamato and Isokaze were sunk by the offensive conducted by the U.S. forces at the Kagoshima-ken’s  Makurazaki offing.

After the war Kure-shi together with a non-governmental organization conducted diving investigation and as a result the location where Yamato was sank was revealed, but the place of sinking for other five ships including Isokaze could not be ascertained. It was said that that this time was the first occasion to know the sinking position of ships besides Yamato.

Hanato Tadaaki the Chinese branch manager assistant of the "Fukada Salvage Construction" that investigated Isokaze said that "when it is possible, apart from Isokaze I would like to investigate the ships which are not found yet."


   So, more historical facts about the sea battles will come to light in due course.
