Ⅰ Continuous Expansion ofJapanese Aerospace Industry

After the end of the Second World War, the aerospace industry in Japan expanded steadily
to satisfy its own defense requirements, but in recent years, participation in international joint
development of civil aircraft has increased. In space operations, development of transportationand satellite systems has been promoted and increased. In this way, the Japanese aerospaceindustry has grown its position to stand alongside those in the US and EU.

completed and started its operation.
Demand led by passenger transpor t is expected to
grow steadily, and Japanese manufacturers are actively
developing and manufacturing civil aircraft. Production
volume has been on the rise in recent years, and civil
aircraft manufacturing now outstrips defense aircraft
manufacturing. However, the pandemic of COVID-19
since the beginning of 2020 has brought sudden
shrinkage to the civil aircraft market, and it is assumed
severe situation to this field will continue for several
years. In the 1960s, Japan focused on the YS-11 transport
aircraft and other similar domestic development projects.

More recently, international joint development has
become mainstream due to the increase in aircraft
development-related risks, as the demand of wide-bodyaircraft has grown globally. Currently, Japan is playing
a central role in the development of aircraft such as the
Boeing767, 777, 777X, and 787, and engines such as theV2500, Trent1000, GEnx, GE9X, PW1100G-JM, etc.
In the aircraft OEM business segment, we are proud of
the HondaJet to become the most delivered business jetin its class. And recently, development of the Urban Air
Mobility ongoing in Japan is attracting attention.

1. Significance of Aerospace Industry

2. Aircraft Related Activities

3. Space Related Activities

The aerospace industry is characterized by the following
strategic components:
・ By integrating advanced technologies with high-grade
materials and components, the aerospace industr yutilizes a wide range of supporting industries, andits technology also spreads to other industries, thus
benefiting the economy as a whole.
・ Thr ough high-speed transpor tation, disasterprevention and other similar activities, this industry
contributes to improve the daily lives of the people ofJapan.
・ As one of the most important components of defense,
the aerospace industr y is directly linked to national
security.

Japanese space-related projects are also world-standard
projects. We have successfully developed launch vehicles
such as the M-V, H-IIA/B, and Epsilon rocket, and in thesatellite field we have contributed to the development ofvarious engineering test satellites, marine and terrestrial
observation satellites, communications, broadcasting andglobal navigation satellites, etc., including weather satellites
such as the HIMAWARI 8 & 9.
The H-IIA/B launch service operations were transferredto the private sector, and by the H-IIA, the company
performed a successful commercial launch of a Canadian
communication satellite in 2015, UAE earth observation
satellite in 2018, UAE Mars spacecraft in 2020 and U.K.
Inmarsat communication satellite in 2021. The H-IIB rocket,
an upgraded model of the H-IIA, was mounted with theunmanned H-II Transfer Vehicle (HTV) to carry supplies tothe International Space Station, and all nine launches, fromits first launch in 2009 to the last launch in May 2020, weresuccessful. We have achieved an extremely high 98% launch
success rate for the H-IIA/ B launch vehicles. The Japan
Aerospace Exploration Agency (JAXA) is now developing
a new key rocket, the H3, to serve as the successor to
the H-IIA/B. This new rocket will be highly competitive
internationally. Together with the Epsilon rocket, the latest
compact solid- fuel rocket, hopes are high for the further
development of the Japanese rocket launching sector.
In the satellite sector, two satellites ordered by a Turkish
government-run communications company are successfully
delivered in orbit. Qatar has also placed an order for
a communications satellite, and this was launched in
November 2018. Japanese satellite manufacturers are using
their advanced technical capabilities, high quality, andcompetitive costs to open up the overseas market. At thesame time, with regard to domestic satellite demand, there
is an expectation for planned governmental procurement,such as the shifting from the current four quasi-zenithsatellites to a eleven quasi-zenith satellite system in orderto create a new Japanese global positioning system (GPS),the development of the Engineering Test Satellite 9 and thesatellite successor to the ALOS-2, Satellite Constellation
Plans for Security Applications, those are on the new Basic
Plan for Space Policy.
In December 2020, HAYABUSA 2 has returned to the earth
with the sample of the Ryugu asteroid.
In addition, the Smart Lander for Investigating Moon (SLIM)
successfully landed on the Moon in January 2024, the fifth
lunar landing in the world.
Japanese companies are developing elemental technologies
and striving to increase reliability while reducing costs.

T-4 Intermediate Jet Trainer (Kawasaki Heavy Industries, Ltd.)For a certain period after the end of the war, Japan was
forbidden from any activities related to the development
and production of aircraft, and our aerospace industry
thus fell behind those of the US and Europe. Startingwith the licensed production of defense aircraft, national
development and production systems have grown. The
development and manufacture of defense aircraft forms
the foundation of the Japanese aerospace industr y. In
recent years the F-2 fighter (a joint Japan-US project),the OH-1 observation helicopter, the T-4 and T-7 trainer,
and the US-2 search & rescue flying boat have beensuccessfully developed and manufactured. The P-1 Fixedwing Maritime Patrol Aircraft has been in operation since2013, and the C-2 Transport Aircraft has begun its delivery
to the base in March 2017. Japanese manufacturers are
participating in the manufacture of the F-35A fighter
jet, helping to further strengthen the foundation of theaerospace industry. Delivery of the F-35A has begun in
2018. Moreover, In 2020, the next fighter(F-2 successor)
business had been launched under the leadership ofJapan, and on December 14,2023, the Japan, the United
Kingdom, and Italy held a meeting of defense ministers
to establish an efficient collaboration system in the Global
Combat Air Programme (GCAP), which is being jointly
developed under the scheme called “GCAP International
Government Organisation(GIGO)” and Founding Treaty
was signed. In a joint statement, the minister of the three
countries signed the “Convention on the Establishment of
GCAP Government Agencies” and stated that GIGO would
lay the foundation for strengthening the defense industrial
base of each country and deploy the next generation offighter aircrafts by 2035. And in 2021, development of the
UH-2 Multipurpose Helicopter, successor to the UH-1J, has

4. Aerospace Facts & Figures
Boeing 777/777X/787 produced by Japan also decreased
significantly in 2020 due to the impact of COVID-19, but
is beginning to turn upward from 2023. Going forward,
a steady increase of defense aircraft production is
expected, as aircraft procurement and maintenance is
expected to increase from 2023 onward, based on the
Defense Buildup Program formulated at the end of 2022.
Demand for commercial aircraft is on a recovery trend
and is returning to pre-COVID-19 levels, but as Boeing's
production recovery is delayed, we cannot be optimistic
about Japan's future aircraft production.
Although the turenover of Japanese aerospace industry issmall compared to that of the U.S. and EU, it is expected
to expand in all areas, including defense aircraft andspace-related products, in addition to the expansionof commercial aircraft production due to the end of
COVID-19.

The turnover of Japan's aerospace industry in 2022 is
1,712 billion yen, an increase of 15.8% from last year's 1,478
billion yen. The breakdown of the turnover is as follows:
1,409 billion yen for the aircraft sector and 303 billion yen
for the space sector (estimated value). Components forcivil aircraft destined for overseas customers and defense
aircraft account for a large share of Japan's aerospaceturnover.
While production for defense aircraft increased slightly or
remained flat in line with the defense budget, production
for commercial aircraft reached a record high in 2019,
mainly due to the increased production rate of the
Boeing 787. In 2020, COVID-19 caused a significant
decrease in commercial aircraft production and demand,and the production rate of the Boeing 777/777X/787
produced by Japan was also down significantly, but isstarting to turn upward in 2023. The production rate of

type, defense demand accounted for 32% of total aircraft
production at 451 billion yen, and commercial aircraft
accounted for 68% at 958 billion yen. The composition
ratio of defense demand has remained at around 30%
since 2013 due to the expansion of expor ts of civil
aircraft, but due to the decrease in civil aircraft during
COVID-19 period, and is on the rise again, coupled with
the increase in the defense budget.

（2）Space Business
The estimated turnover of the space sector in 2022 was
303 billion yen, down 4 billion yen from the previous
year. However, with the success of successive launchesof the H-IIA/B rockets, the turnover is expected toincrease further, including orders from overseas.
(Billions of Yen)In addition, development of the H3 rocket, the successor
to the H-IIA rocket, has been under way since 2014,
and with the successful launch in February 2024, it has
moved into the mass production phase. The productionof rockets and satellites accounts for about 85% of total
space equipment production.

Aircraft for National Defense

Japan’s defense aircraft industry was reborn in 1952 with aircraft such as the F-86F and
T-33A manufactured under license from the United States. In 1958, Japan’s first jet trainer
was developed and produced. Many significant steps in the advancement of the design andmanufacturing technologies have followed. Today, Japanese aircraft manufacturers have theirown capability to develop, produce and maintain a wide range of defense aircraft, such as fighter,transporter, patrol plane, trainer and search & rescue vessel, which has thus contributed to thenational defense.

1. Most Advanced Fighter

2. Aircraft Development

・F-2
Developed jointly by Japan and the United States, theF-2 fighter is used in multiple roles, such as tactical air
suppor t, close air suppor t and defensive counter-air
operations. Highly regarded both at home and overseas,
this fighter features a host of advanced technologies
developed in Japan.

Japan Ministry of Defense is currently developing, andoperating the following types of aircraft:

・F-35A/B
The F-35A (CTOL; Conventional Take-Off and Landing)is the latest fighter being introduced as the successor to
the F-4 fighter. With the exception of a few completed
aircraft, air frame and engine final assembly andinspection, as well as component manufacturing, areperformed by Japanese companies. Participation in the
manufacturing of the F-35A by Japanese manufacturers
will contribute to strengthen the domestic businessbasis, and to support good operations. Delivery of the
F-35A to the base has begun in January 2018.
And the F-35B, STOVL (Shor t Take-of f and Ver ticalLanding) aircraft, will also be introduced.

F-2 Fighter (Mitsubishi Heavy Industries, Ltd.)

10・Search & Rescue Flying Boat
Development of the US-2 Amphibious Search & Rescue
Flying Boat, successor to the US-1A, has started in 1996,
and succeeded its first flight in December 2003. Delivery
to the base has started in March 2007.

・Unmanned Aerial Vehicles
The Ministry of Defense has undertaken the researchof unmanned aerial vehicles. Studies to evaluate
conversion of the F-104 Fighter for pilotless operation
was per formed, and the ministr y has developed an
unmanned aircraft research system with autonomous
flight functions capable of automatic landing.
・Trainer
The Ministr y of Defense has been designing anddeveloping a trainer such as the T-4 and T-7 in Japan.
Both the airframe and engine of the T-4 intermediate
trainer was fully developed and produced in Japan.
Making the most of its excellent agility, the aerialcombat research aircraft (nicknamed “Blue Impulse”)
appeals to people with flying displays held at various air
bases throughout Japan.

to establish an ef ficient collaboration system in the
Global Combat Air Programme (GCAP), which is being
jointly developed under the scheme called “GCAPInternational Government Organisation(GIGO)” andFounding Treaty was signed. In a joint statement, theminister of the three countries signed and set the goalfor deployment by 2035.
These technical capabilities of defense aircraft not
only contributed significantly to the development andmanufacture of civil aircraft as the ripple effect, but also
have widely spread to other industries, and formed thebasis of Japan's industrial technology.

・The next fighter
The next fighter successor to the F-2, with the capability
against future threat is under development. The
development has started from 2020, by international
collaboration led by Japan. And in 2020, F-2 successor
business had been launched under the leadership ofJapan, and on December 14,2023, the Japan, the United
Kingdom, and Italy held a meeting of defense ministers
C-2 Transport Aircraft (Kawasaki Heavy Industries, Ltd.)・Fixed-wing Maritime Patrol Aircraft and Transport Aircraft
Development of the P-1 Fixed-wing Maritime Patrol Aircraft,
successor to the P-3C, and the C-2 Transport Aircraft,
successor to the C-1, has begun at the same time in 2001. By
this method, common processes of these two aircraft wereshared and reduced overall development costs. The P-1
succeeded the first flight in September 2007 and started thedelivery to the base from March 2013. The C-2 successfullycompleted its first flight in January 2010 and the delivery to
the base has begun in March 2017.

Civil Aircraft for Steady Growth Expectations

3. Domestic Development of Civil Aircraft

Aiming at risk reduction and being market oriented, the development of civil aircraft is carried out
in multinational projects. Japan is proactive in the joint development of the Boeing777, 787, andother models.
In the field of aircraft OEM business, the HondaJet is well known and operated worldwide. And the
Mitsubishi SpaceJet is under development.

1. Increases in Demand for Passenger
and Transport Aircraft

2. Japan’s Role in Multinational
Development

Worldwide demand for passenger aircraft expanded ata record pace from 2005 after recovering from a low
economic growth following the September 11, 2001
terror attacks. The demand was boosted by China, India
and other rapidly growing emerging economies, andby good performance of low-cost carriers around theworld. The demand plunged again in the aftermath of
the global financial crisis in 2008, then, recovering again
worldwide demand for passenger aircraft from 2010.
And once again, in 2020, demand of passenger aircraft
has decreased suddenly because of the COVID-19. Afterthe recovery from COVID-19, this demand is expected
to bounce back.

Japanese companies are active in projects such as
those shown in the following table (Par ticipation inInternational Projects), and they play an impor tantrole in the global production of aircraft. Japan has been
involved in multinational development of aircraft such as
the Boeing767, 777, and 787, and has steadily increased
its production share. In July 2015 Japanese companies
were officially contracted to manufacture approximately
21% of the main structural components used in the new
Boeing777X passenger plane. Many Japanese companies
are also participating in the production of the Airbus
A320, A330, A350 XWB, and A380.

Japan developed the YS-11 60-seater transport aircraft
in 1964 as the first national developed civil aircraft.
The MU-2, FA-200, FA-300 and MU-300 business jets
followed during the period until 1980. And nowadays,
the HondaJet has won the most delivered business jetin its class for five consecutive years from 2017, andcurrently over 200 HondaJets are operated worldwide.
And the Mitsubishi SpaceJet (formerly known as MRJ)
officially announced the discontinuation of development
program on February 7, 2023.

World Class Rockets

Japan is continuously maintaining and operating rocket launch, tracking, and control functions inorder to keep its independent space development and utilization capabilities. Successful launchesof the H-IIA, the world’s top-class liquid propellant rocket of Japan, has brought launching orders
from the foreign satellite operators. And the development of the H3, the successor to the H-IIA/
B, is under way. Japan has also succeeded at developing the Epsilon rocket, a solid-fuel rocket
designed to be compact, offer high performance levels, and low cost.
Japan’s first space experiment was conducted in 1955
with the testing of a 20-cm pencil rocket. Since then, we
have fully applied our technical strengths, and this effort
has allowed Japan to take its place among the world’s
leading space-exploration nations.

1. Liquid Propellant Rockets
In 1975, Japan successfully launched
the N-I with the assistance of the UnitedStates. Following this, development of
the N-II and H-I were advanced withthe aim of improving both performanceand the level of domestic production;accordingly, 1994 saw the successful
launch of the H-II, a launch vehicle
that was produced completely in Japan.
Using liquid hydrogen as fuel and liquid
oxygen as an oxidizing agent, thisrocket’s engine offered extremely highlevels of performance.
In 2001, the Japanese H-IIA wassuccessfully launched, and in theprocess, it became Japan's primar ylarge-scale launch vehicle. This rocket
was developed by the Japan Aerospace
Exploration Agency (JAXA), and thelaunch business was transferred to a

private company in 2007. The successful launch of the
H-IIA launch vehicle No.48 in Januar y 2024, together
with the success of all nine launches of the H-IIB launchvehicles brought our successful launch rate to 98.2%. We
are receiving orders for the launch of foreign satellites,
and we anticipate that Japan will soon be active on
the global stage. Since 2014, development has been
under way of the new H3 key rocket, and H3 launchbooster, the SRB-3) with proven track records will be
used for the later stage rockets. It is aimed to cut costsby half and reduce work times in order to follow the
H-IIA in securing further launch orders from foreignsatellites.

2. Solid Propellant Rockets
Japan developed the global top class M-V solid-fuelrocket, which achieved success on a global scale
through the launch of scientific satellites, solar
obser vation satellites, and astronomical obser vation
satellites such as the HAYABUSA, however theoperation of this rocket has finished in 2006.
The Epsilon launch vehicle was developed as acompact, high performance, low cost next-generation
rocket which uses elements of the M-V and H-IIA. The
first Epsilon launch vehicle prototype was launchedsuccessfully from the Uchinoura Space Center in
Kagoshima Pr efectur e in September 2013. The
development of the Epsilon launch vehicle represents
a new era of development, including innovative newtechnologies such as self-inspection and mobile
operation, while making good use of the technology
of existing rocket motor. Expectations are high for
its use as a deliver y system for small satellites, asegment which is expected to see a great deal of
future growth. In December 2016, Epsilon No.2 haslaunched ERG Satellite "ARASE", in Januar y 2018,
Epsilon No.3 has launched small high resolution radar
satellite "ASNARO-2", in Januar y 2019, Epsilon No.4
has launched "RAPIS-1" (RAPid Innovative payload

The most imperative usage of space is to assure national security, social peace and activities. In
1970, Japan launched its first satellite, OOSUMI, becoming the fourth spacefaring nation to launcha domestically manufactured satellite using a rocket of her own. Then in 1977, Japan successfullylaunched a geosynchronous orbit satellite. With technical capabilities rating among the best in theworld, Japan is currently receiving orders from overseas for satellite launches, and is involved in
the development and production of satellite systems, onboard sensors and components.

The Radar Earth Obser vation satellite "ASUNARO-2"
which was compatible with small size, light weight, lowcost, high resolution by restricting lifespan, observation
width and function than the conventional satellite, waslaunched in January 2018, and its taken image has beenreleased in March.
Development of the Greenhouse gases Obser ving
SATellite-2 "GOSAT-2" was launched in October 2018,
and the data has been released to the public sinceAugust 2019.

3. Communication & Broadcasting Satellites
1. Weather Satellites
The first satellite launched for practical use by Japan
was the HIMAWARI weather satellite of 1977. Following
this, a total of seven weather satellites were put into
operation, allowing valuable weather-related information
to be supplied domestically and throughout the Asian
region.
As a successor to these earlier weather satellites,
HIMAWARI 8 was launched in October 2014, and was inoperation until November 2022 when HIMAWARI 9, thestandby satellite in orbit launched in November 2016,has begun operations.
Furthermore, development of the HIMAWARI 10 has begun.

changes in topography before and after the September
2014 eruption near the summit of Mount Ontake, as
well as ash fall conditions. The Global Precipitation
Measurement (GPM) satellite launched in Februar y2014 contains the Japanese-developed Dual-frequency
Precipitation Radar (DPR), which has been used toprovide observation data to the public since September
2014. Numerous satellites, including the SHIZUKU
water circulation monitoring satellite, launched in May
2012, have been launched as part of the GPM mission,
led by the U.S. and Japan. These satellites are providing
global precipitation data ever y three hours to relatedorganizations for use in weather forecasting, flood
prediction, and other individual purposes.

2. Remote Sensing
The impor tance of remote sensing missions suchas global obser vation and resource sur veying is
expected to become ever more important. In the global
monitoring sector, the Advanced Land Obser ving
Satellite-2 "DAICHI-2" (ALOS-2) was launched in May
2014. It features PALSAR-2, a terrestrial visualization
radar with a higher resolution and wider monitoringarea than the sensor of former satellite DAICHI. Since
November 2014 it has provided observation data used
for mapping, regional obser vation, disaster conditionassessment, resource exploration, and more. Its
observation data has been successfully used to confirm

Japan has launched the SAKURA series of communication
satellites and the YURI series of broadcasting satellites,
and has developed the technologies which enable
to make practical use of satellites. Satellites madein foreign countries used to dominate the Japanesemarket, however successes like the exclusive receipt by
Japanese companies of orders for the TURKSAT-4A/4B
and the Es'hailSat satellite help to advance Japan's
competitiveness in the international market.
The development of the next-generation Engineering
Test Satellite 9, aiming 2025 launch, is under way andthe purpose is to develop and verify the upgranding
satellite and communication missions, so as to further
strengthen Japanese international competitiveness.

5. Other Projects
Japan is also par ticipating in using satellites for
astronomical observation and space science exploration,
as well as for technology validation. The HISAKI
Spectroscopic Planet Obser vator y for Recognition ofInteraction of Atmosphere, launched in September
2013, is attempting to shed light on the universal andparticular characteristics of the Jovian magnetosphereby performing spectroscopic obser vation of extremeultraviolet rays from earth orbit.
HAYABUSA 2, a successor to the highly successful
HAYABUSA (MUSES-C) science exploration spacecraft,
was launched in December 2014, and has reached
the Ryugu asteroid in June 2018, where to collect the
information to research the bir th and the evolutionof our solar system and the materials of life. In
Februar y and July 2019, HAYABUSA 2 has succeed
in touching down to the R yugu, and sample werecollected successfully. In December 2020, the capsule of
HAYABUSA 2 has landed on the desert of Australlia andthe sample analysis is being conducted.
The Smart Lander for Investigating Moon(SLIM) was
launched by the H-IIA Launch Vehicle No. 47 in July
2023, and successfully made a highly-precise landing on
the Moon in January 2024.

4. Quasi-Zenith Satellite Systems
Positioning information is used in various applications,such as vehicle navigation systems and GPS-equipped
mobile phones. Usage of this information is expected
to continue to grow. Japan currently uses primarily U.S.
GPS, but the Quasi-Zenith Satellite-1 "MICHIBIKI" waslaunched in September 2010 for complementar y andaugmentation services.
In 2017 satellites 2 through 4 has been launched, and in
November 2018, precision GNSS service has started. In
addition, satellites 5 through 7 are scheduled to be launchedin 2023, to create the seven-satellite structure. And continuous
development operation for eleven-satellite structure areplanned afterwards.

Japan, Canada, and the European Space Agency (ESA), from its inception. We have also supplied the
KIBO Japanese Experiment Module. We are also making significant contributions to the completionand operation of the ISS project by supplying it via ”KOUNOTORI” H-II Transfer Vehicle (HTV). And
Japan will also take part in NASA’s Lunar Gateway project.

1. International Space Station
Orbital assembly of the International Space Station (ISS)began in 1999, and was completed in July 2011. Japan
has supplied the KIBO Japanese Experiment Module(JEM), the largest ISS space experiment module. KIBO
was delivered to the ISS by the space shuttle, and began
full-fledged operation from July 2009. KOUNOTORI, aspace station supply vehicle, then began transport ofexperimental devices and materials.
A close approach system designed in Japan for docking
KOUNOTORI is used in the U.S. cargo deliver yspacecraft Cygnus.
Many Japanese astronauts, such as Koichi Wakata,
Soichi Noguchi, Naoko Yamazaki, Satoshi Furukawa,Akihiko Hoshide, Kimiya Yui, Takuya Onishi, andNorishige Kanai were on duty at the ISS and have taken
part in assembly of the KIBO and docking operations for
the H-II Transfer Vehicle. Astronaut Akihiko Hoshide,
