History of Our Business Evolution and Value Creation
Through manufacturing that leverages our unique technological capabilities in the rubber and plastic fields that
we have cultivated since our founding, we respond to the needs of the times and provide new value to the world.
Founding to 1970s

Carrying on the spirit of Kiichiro Toyoda to develop rubber and plastic parts
In the late 1930s, Kiichiro Toyoda, who recognized theimportance of rubber parts, established a rubber research
department within the automotive division of Toyoda AutomaticLoom Works. This was the origin of Toyoda Gosei. KiichiroToyoda would later go on to found Toyota Motor Corporation.
Kiichiro’s passion for research was carried over to Nagoya
Rubber Co., Ltd., which was established in 1949.
In the 1950s, Nagoya Rubber focused on the development andproduction of rubber parts for automobiles, and became thefirst JIS-certified plant in Japan to manufacture hydraulic brakehoses for automobiles. Nagoya Rubber also took on the1949

challenge of producing plastic steering wheels, which had
previously been made of hard rubber. In 1954, the injection
molding process was used to produce plastic steering wheels
for Model FA trucks, and later, the same process was also used
for the plastic steering wheels in the Toyopet Crown model.
From the 1960s onward, Nagoya Rubber expanded its businessas Japan’s automobile industry continued to grow and develop.
In 1967, the Company opened the Inazawa Plant to produce
plastic parts by injection molding, and subsequently expanded its
production bases mainly in the Owari area. In 1973, the Company
changed its name to the current Toyoda Gosei Co., Ltd.

In 1952, at the suggestion of Toyota MotorCo., Ltd., one of our major customers, weinstalled a 48-ounce injection molding
machine manufactured by Watson-Stillman
Co. of the United States. While some wereapprehensive about adopting injection
molding, which was still an excessive
investment even with financial support fromToyota Motor Co., Ltd., we took a leap of faithand succeeded in putting the equipment intooperation. This marked the beginning of theage of plastics for automotive parts.

1980s to 2000s

Growing into a global company through commitment to research and development
As a member of the Toyota Group, our development andproduction of rubber and plastic parts for automobiles
has expanded into various fields since the 1980s.
As a polymer manufacturer, we aim to be a developmentoriented company and have strengthened ourdevelopment capabilities by establishing the Kitajima
Technical Center in 1995 and the Miwa Technical Centerin 2009.
We also turned our attention to fields in other industries,
and based on our thin-film formation technology
developed in the automotive parts business, from 1986,

we took on the challenge of researching blue LEDs,
whose development had numerous technological hurdles
that were considered difficult to overcome. In 1995, we
succeeded in achieving mass production of blue LEDs.
Until the end of the 1980s, Toyoda Gosei’s overseas
markets consisted of Taiwan and North America under afour-company system, but in the 1990s, we accelerated
our overseas expansion. Following North America andAsia, we expanded to Australia, Europe, Central andSouth America, and Africa, and have now grown into aglobal company with 62 overseas companies.

The challenge of developing airbags

World’s first

Toyoda Gosei boasts the top share in theJapanese airbag market. It is easy toassume that Toyoda Gosei began toproduce airbags as part of its steering
wheel manufacturing business, but infact, the Company felt a sense ofurgency over new commercial rights for
Toyota Motor Corporation’s first airbag,
and the Company felt that it had todevelop airbags as quickly as possible,
resulting in a bold new challenge against
fierce development competition.

LEDs are being used in a growing range of fields as
an environmentally-friendly light source because of
their superior energy-saving performance. It was thecommercialization of blue LEDs in the 1990s thatmade LED products possible. In 1986, under theguidance of Professor Isamu Akasaki of Nagoya
University’s Faculty of Engineering and with thecooperation of Toyota Central R&D Labs, Toyoda
Gosei began developing a gallium nitride (GaN)based blue LED, which was certified as a success in1991. Until then, the development of blue LEDs wasthought to be impossible. The challenge, which was
the first of its kind in the world, was a series ofuncertainties and obstacles.

History of Our Business Evolution and Value Creation and Our Competitive Advantages

2010s to Future

Contributing to the future with a focus on safety, comfort, and decarbonization
The 2010s brought new challenges for companies, such asmeasures to prevent global warming and the achieving of asustainable society. In the automotive market, vehicles that do
not rely on petroleum fuels, such as BEVs (battery electricvehicles), are expected to play a leading role in the future,forcing major changes.
We have developed high-pressure hydrogen tanks for FCEVs(fuel cell electric vehicles) using our polymer technology. Thistank, jointly developed with Toyota Motor Corporation, is being
used in Toyota’s second-generation Mirai model, which started
mass production in 2020. In response to the shift to BEVs, wewill contribute to the reduction of traffic fatalities by offering

2010

optimal solutions for airbags and seat belts that accommodate
the changes in vehicle structure, and we will also innovate
vehicle design and manufacturing with our polymer technology
for realizing new mobility. Also, we will develop and recycle
high-performance materials by utilizing our expertise in polymer
materials, and will not only utilize our developed materials andtechnologies within the Company but also sell them outside theCompany, and through these new businesses, we will contributeto achieving a decarbonized and recycling-oriented society.
We will continue to provide value to society in the three areas ofsafety, comfort, and decarbonization through the use of polymer
technology.
