Type 89 Otsu (I-Go) Tank
Type 89 Medium's codename was
"I-Go". I-Go's design refered to the Vickers Medium C Tank which was the basis
for the Type 89. Only one Vickers Medium C Tank was ever imported. Japanese planners
decided to produce their own version at home using an air-cooled diesel instead of the
Vickers gasoline engine. Major Tomio Hara developed the unique bell crank suspension used
in this model. Variants included the SS-Ki Engineer tank.

Type 92 Heavy Armored Car, Type 92 Light Tank "Ju-Sokosha"
This model offered an improved suspension.
Model 92 was deployed to the Cavalry. The Type 92 Light Tank was officially classified as
a heavy armored car. In western sources it has been listed both as a heavy tankette or as
a light tank. Western records also list it as a Combat Car. This vehicle was designed for
the Cavalry. The early designs called for wheeled armored car, because of terrain
conditions/considerations, the design was changed to a tracked version. The Combat Car had
4 versions. The Prototype, the early production, the late production, and a amphibious
version called the Type 92 A-I-GO. The main difference between the early and late
production models was in the running gear. The earlier running gear tended to breakdown.
The late production model had larger spoked rubber tired wheels.

Medium Tank in the Japanese inventory. Careful research has found this label to be an
error. The Type 94 Medium Tank is the Type 89 Medium Tank Otsu.

Model 94 Tankette "TK"
Model 94 Tankette had a codename,
"TK", which means "Tokushu (Special) Ken-in sha (Tractor)". The TK's
true purpose was to pull the supply/toxic gas/bleaching powder (to counteract toxins)
trailer.
In the late 1920's, the Japanese purchased six
British Carden-Loyd Mark machine-gun carriers, and two Mark Vlb carriers for testing. As a
result of trials the Japanese decided to develop a small vehicle in Japan based on what
was learned. The prototype was built in 1933-34 by the Tokyo Gas and Electric Industry
(later known as Hino Motors) and after trials in both China and Japan it was standardized
as the Type 94 tankette. Oddly, American sources have always referred to it as the Type 92
tankette.
The hull of the tankette used a riveted
construction, with the engine and driver at the front and the small turret at the rear of
the hull. A large door was provided in the rear of the hull so that stores could be
loaded. Armament consisted of a single 6.5mm machine-gun in a turret with manual traverse.
The suspension was designed by Major Tomio Hara and was similar to most Japanese tanks. It
consisted of four bogies, two on each side. These were suspended by bell-cranks resisted
by armored compression springs placed horizontally, one each side of the hull, externally.
Each bogie had two small rubber-tired road wheels with the drive sprocket at the front and
the idler at the rear. There were two track-return rollers. When in service, the Type 94
was found to be very prone to throwing its tracks when it made a high speed turn. Further
redesign work was carried out on the suspension and the small idler was replaced by a
larger idler, which was now on the ground... it did not solve the problem. An air-cooled
gasoline motor that developed 35hp @ 2,500rpm powered the tank. Armament initially
consisted of a single Type 91 6.5mm machine gun, although in later model this was replaced
by a single 7.7mm machine gun. Some appear to have been fitted with a 37mm gun, but this
is unconfirmed.
The primary role of the Type 94 was to carry
supplies in the battlefield area but it was often used in the reconnaissance role for
which it was totally unsuited as its armor could be penetrated by ordinary rifle bullets.
In 1936, each Japanese Infantry Division had a Tankette Company that had 6 Type 94s, for
use in reconnaissance role. It was often used to tow a tracked ammunition trailer in a
fashion similar to the British and French tankettes of this period. The Type 97 replaced
the Type 92 in service. There was also a chemical/biological trailer constructed for this
tank.

Model 95 Ha-Go Light Tank
The Type 95 was developed to meet the
requirements of the Japanese army in the early 1930's. The first two prototypes were
completed in 1934 by Mitsubishi Heavy Industries. These were tested in China and Japan and
finally standardized as the Type 95. Mitsubishi called the tank Ha-Go, but the army called
the tank "Kyuu-Go" which simply means 95 (due to misunderstanding, this is
sometimes spelled as Ka-Go). Over 1100 were completed before production ended in 1943.
However, there is a possibility that the tank remained in production until 1945. This
source is unconfirmed. In 1943 a few Type 95 were modified to carry the 57mm cannon as
fitted to the Type 97. This tank was called the Ke-Ri. The Ke-Ri was not successful owing
to the cramped turret. It was then decided to modify the turret ring and place a Type 97
turret on a Type 95. This new tank was called the Ke-Nu. The type 95 was a useful vehicle
in China but met it's operational end when facing the M4 Sherman and American anti tank
equipment.

as a nickname. Any reference to this name is actually referring to the Model 95 Ha-Go

Type 95 Heavy Tank
The Type 95 was the final version of the Japanese
multi-turret designs. The front sub-turret housed a 37mm gun, while the main turret held a
70mm gun facing forward and a 6.5mm machine gun in the rear. The tank also had a
rear-facing sub-turret armed with a 6.5mm machine gun. The armor was of riveted
construction running from 12mm to 30mm in thickness. The tank ran on 9 leaf sprung road
wheels supported by 4 return rollers. The rear sprocket drove the tracks. The engine was
gasoline driven (Aircraft Type, 6 cylinders, liquid cooled) and developed 290hp which
resulted in the top speed of 13.7 mph. Only one pilot model was built in 1934.

Type 97 Chi-Ha Medium Tank
Some 3000 vehicles were produced by Mitsubishi
during this model's "run". The following specialized tanks were produced:
recovery, flail mine clearers, engineer, bridge layers, 20mm and 75mm anti-aircraft, and
self propelled guns. These vehicles made very little impact on daily operations owing to
their small numbers. Late in the war the Navy installed a 120mm gun in a limited number of
these tanks.

Type 97 w/47mm Cannon Shinhoto-Chi-Ha
Also known as a Type 97 "special"
From 1942 onwards, the Model 97 was armed with the high
velocity 47 mm cannon. This model was also known as the Shinhoto Chi-Ha. Mounting this
cannon required a larger turret design. This design was probably the best tank Japan
produced up to 1945. The term Shinhoto means "new turret". When developing Type
97 Medium Tank, "Chi" was first used as the code name of the medium tank.
Because the Type 97 was a third medium tank (previous two are Type 89 Ko and Otsu), the
Type 97 was named as Chi-Ha (Ha is the third letter of the Japanese alphabet). Note that
Chi had not been used before Type 97. Before that, the code name of the Japanese tank is
the simple sequential name like Yi-Go, Ha-Go.

Type 4 Chi-To Medium Tank
This design never went beyond prototype before
the war ended. Chi-To's development began in 1942, to succeed Shinhoto Chi-Ha. In the
first plan, the hull would be modified type of Chi-Ha, and main armament would be high
velocity 57mm ATG. The plan changed in July 1943, to arm with 75mm high velocity cannon
(copy of Bofors M29 75mm AAG) to catch up with world standard specification. So, it was
decided that Chi-To would be designed all over again - from the ground up. The first
prototype was finished in May 1944. Owing to war material priorities and other factors,
only 6 were ever completed.
