The Wright brothers made the first motorized flight in 1903.
Seven years later, the first flight in Japan was made by Captain
Tokugawa, flying a Farman airplane at Yoyogi Army Field. In 1911,
the first Japanese engineered and manufactured airplane "Kai-shiki
(Type Kai) No.1" made the first flight successfully at Tokorozawa
Airfield (currently Tokorozawa Air Memorial Park).
In 1917, Chikuhei Nakajima (33 years old at that time), who
retired as Engineering Captain of the Navy, contemplating developing
a public aircraft industry, set up the "Airplane Institute"
at Ojima Town close to Ota Town in Gunma Prefecture (currently
Ota City). The building was a simply remodeled sericultural hut
along the Tone River. In the beginning, there were only nine
members, but in the following year they built their first airplane;
the first "Nakajima Type 1" with a U.S.A. made engine.
But the first Type 1 sadly crashed after take off. The second
Type 1 also failed, and the third one finally did take off, but
hit a ditch upon landing and also crashed. In that age, it was
said that there was a pasquinade in Ota Town, "Too much
paper money, too high a price for rice. Everything goes up, except
Nakajima planes".
After the trials and tribulations in the foundation period, the
sixth Nakajima Type 4 was finally completed, and flew over Ojima
Town proudly.
In 1919, the first mail plane contest was held between Tokyo
and Osaka. Nakajima Type 4 cleared the distance in 3 hours and
18 minutes, and defeated the imported planes. Together with the
prize money of 9,500 yen, it provided a good opportunity to demonstrate
their engineering superiority to the public. The person who instructed
this project both in engineering and management was Jingo Kuribara.
He was not a flashy person but rather shy. A born engineer, he
studied hard and his intellect captured the era. Kuribara at
that time was General Manager of the Donryu Factory, and also
General Manager of the Ota Factory. He played a leading role
in developing later Nakajima Aircraft. In the management of the
Institute, Kuribara exerted his energy to find the most competent
people.

In 1920, the military having noticed drastic progress in aircraft
technology during World War I in Europe, invited a training team
from France and also started to seriously study licensed production
of airplane bodies and engines. Nakajima Aircraft dispatched
Kimihei Nakajima to France for a long period in order for him
gather information and technologies regarding airplanes. With
this as a turning point, Nakajima Aircraft received a large order
from the military, and tremendous growth followed.
In 1922, the first all-metal airplane, Nakajima Type B-6 was
completed. It was modeled after the Breguet 14. The Type B-6
and named "Kei-Gin Go (light silver)" since the revolutionary
light weight metal at that time, duralumin, was used. It was
revealed at the "Peace Memorial Tokyo Exposition" and
got high reviews. (The picture below shows the B-6. The engine
was a Rolls Royce water cooled V12, 360PS)
In 1922, Ichiro Sakuma was looking in the suburbs of Tokyo
for the site of an exclusive airplane engine factory, and found
one at Kamiigusa, Iogi, Toyotama-Gun (Ogikubo). He bought an
area of
12,540m2 the next year. Construction
started immediately, and the Tokyo Factory was finished in 1924
and began to license and manufacture water-cooled Laurence engines.
Separate working environments (engine production in Tokyo and
body production in Ota) were established at that time.
From the Taisho Era to the Showa Era there was substantial
progress in engineering due to the introduction of foreign technologies.
In 1927, a competition was ordered by the Army to create the
next generation fighter plane. Mitsubishi Internal Combustion
Engine Co., Kawasaki Ship Building Co., Ishikawajima Aircraft
Co. and Nakajima Aircraft Industries all participated. In 1928,
Nakajima produced an airplane with a single high-wing with struts,
named Type NC. In comparison with Mitsubishi and Kawasaki, which
applied German style, water cooled, straight-line-based rugged
designs, Nakajima Type NC had a streamlined and slender body
with an air cooled engine. It resembled the Nieuport Delage in
France, and at a glance, seemed nimble and agile. All Nakajima
planes were designed with flowing elegance as tradition, and
it was said that there was a common understanding among the engineers
that "Real things (airplanes) reaching the pinnacle of engineering
excellence should be beautiful" (The picture below shows
Type NC N0.7)
The engine of the Type NC airplane was changed with a Nakajima
Jupiter 7 type, a Taunend type cowling was attached, and the
entire body was refined with great effort. The plane was then
adopted by the Army as the Type 91 fighter.
At that time, the Navy was studying 1928 Boeing 69B fighters
and 1933 Boeing 100D fighters, but Nakajima was developing an
original fighter named NY Navy Fighter independently to surpass
those imported planes. The N of NY stood for Nakajima and Y was
for the name of the chief engineer, Takao Yoshida. The airplane
being developed was utilizing the Jupiter 7 of English Bristol
Bulldog family, and was called the "Yoshida Bulldog"
but was not adopted by the Army. Nakajima then replaced the chief
engineer with Jingo Kuribara, and changed the engine to a newly
developed Nakajima "Kotobuki (auspicious)", and the
"NY-Kai (NY-II)" was completed in 1932. The marked
improvement in its performance was acknowledged and it was adopted
as the Type 90 carrier fighter. At the dedication and naming
ceremony in Haneda, the name "Hokoku (patriotic spirit)"
was given, and together with other planes from Yokosuka Airforce,
it demonstrated formation aerobatics. Among them, famous aerobatics
performances made by the master trio of Genda, Okamura and Nomura
were given, and they later became to be known as the "Genda
Circus". From here on, Nakajima quickly rose to fame and
later monopolized of the production of Army and Navy fighter
planes.
