Japanese Special Attack Units
During the
Second World War,
Japanese Special Attack Units (Japanese: 特別"'隊,
tokubetsu kōgeki tai, also abbreviated to 特"隊,
tokkōtai), also called
shimbu-tai by the
IJA, were specialized units normally used for suicide missions. They included
kamikaze bombers,
Fukuryu ("Crouching Dragon", suicide scuba divers who would swim under boats and use explosives mounted on bamboo poles to destroy both the boat and themselves), and several types of suicide ships and submarines.
Rocket plane Ohka
The
Yokosuka MXY-7
Ohka (桜花 "
cherry blossom") was a purpose-built
kamikaze aircraft employed by the
Imperial Japanese Navy Air Service towards the end of
World War II. The
US gave the aircraft the
Japanese name
Baka ("fool").
It was a small
flying bomb that was carried underneath a
Mitsubishi G4M "Betty",
Yokosuka P1Y Ginga "Frances" (guided Type 22) or planned Heavy
Nakajima G8N Renzan "Rita" (transport type 43A/B)
bomber to within range of its target; on release, the pilot would first glide towards the target and when close enough he would fire the Ohka's engine(s) and dive against the ship to destroy. That final approach was almost unstoppable (especially for Type 11) because the aircraft gained tremendous speed. Later versions were designed to be launched from coastal air bases and caves, and even from
submarines equipped with
aircraft catapults, although none were actually used this way.
Shinryu
The Mizuno
Shinryu (神龍 - "Divine Dragon") was a proposed rocket-powered
kamikaze aircraft designed for the
Imperial Japanese Navy towards the end of
World War II. It never reached production.
Tsurugi
The
Nakajima Ki-115 Tsurugi (剣 "Sword") was a one-man
kamikaze aircraft developed by the
Imperial Japanese Army Air Force in the closing stages of
World War 2 in late
1945.
Nakajima Ki-116
The
Nakajima Ki-116 was a late-
World War II kamikaze aircraft developed for the
Imperial Japanese Army Air Force. It was essentially a
Ki-84 Hayate with the
Nakajima Ha-45 engine replaced with a
Mitsubishi Ha-112. The design was handled by Mansyu (満州) Aircraft, and thus it is often designated
Mansyu Ki-116.
Baika
The
Kawanishi Baika (梅花 -
"Ume Blossom") was a
pulsejet-powered
kamikaze aircraft under development for the
Imperial Japanese Navy towards the end of
World War II. The war ended before any were built. The design was greatly inspired by the manned version of the German
V1 flying bomb, the Fieseler Fi 103R "Reichenberg".
The
Shinyo (震洋 "Sea Quake") were Japanese suicide boats developed during
World War Two. They were part of the wider Special Attack Units program. These fast motorboats were driven by one man, to speeds of around 30 knots. They were typically equipped with two depth charges as explosives.
Around 6,200
Shinyo were produced for the
Imperial Japanese Navy and 3,000
Maru-Ni for the
Imperial Japanese Army. Around 400 were affected to
Okinawa and
Formosa, and the rest were stored on the coast of Japan for the ultimate defense against the invasion of the Home islands.
Kairyu
The
Kairyu (海龍 "Sea Dragon") was a class of
Kamikaze midget submarines of the
Imperial Japanese Navy, designed in
1943-
1944, and produced from the beginning of
1945. These submarines were meant to meet the invading American Naval forces upon their anticipated approach of Tokyo.
These submarines had a two-man crew and were fitted with an internal warhead for suicide missions. Over 760 of these submarines were planned, and by August 1945, 200 had been manufactured, most of them at the
Yokosuka shipyard.
Kaiten

The
Kaiten (Japanese:回天) was a
torpedo modified as a
suicide weapon, and used by the
Imperial Japanese Navy in the final stages of the
Second World War.
Kaiten means
returning to the heavens.
Early designs allowed for the pilot to escape after the final acceleration towards the target, although whether this could have been done successfully is doubtful. There is no record of any pilot attempting to escape or intending to do so, and this provision was dropped from later production kaitens.

Suicide divers (Japanese:伏龍,
Fukuryu "Crouching dragons") were a part of the Special Attack Units prepared to resist the invasion of the Home islands by Allied forces. They were armed with a
mine containing 15 kilograms of explosive, fitted to a 5 meter bamboo pole. They would dive and stick the pole into the hull of an enemy ship, destroying themselves in the process. They were equipped with a diving jacket and trousers, diving shoes, and a diving helmet fixed by four bolts. They were typically weighed down with 9 kg of lead, and had two bottles of compressed air at 150 bars. They were expected to be able to walk at a depth of 5 to 7 meters, for about 6 hours. This new weapon is only known to have been used a few times operationally:
*January 8th, 1945 Damage by suicide divers to Infantry landing craft (gunboat) LCI(G)-404 in Yoo Passage,
Palaus.
*February 10th, 1945 Attempted attack by suicide divers on surveying ship Hydrographer (AGS-2) in Schonian Harbor, Palaus.
Several deaths occurred during training due to dysfunctions.
