What MEISEI should work on
to achieve a sustainable future.
MEISEI's corporate philosophy is "We continuously contribute to
the development of a safe and secure society by creating innovative
products and services utilizing our unique sensing and communication
technologies." Because this philosophy is well aligned with the SDGs,
we believe that we can contribute signiﬁcantly to achieving these
global goals through our operations. As natural disasters and the severityof the damages they cause have been on the increase in recent years,
our weather observation systems such as radiosonde POTEKA ® anddisaster prevention systems such as the seismic intensity meter, QCAST®
can help prevent and mitigate damages from natural disasters. In thearea of space defense, our satellite-mounted instruments are being
utilized for studies on global-scale phenomena using earth observation
satellites as well as to identify damages from natural disasters andenable quick responses. MEISEI can make a variety of contributions to
the achievement of a sustainable future.

Corporate Prof ile

The Sustainable Development Goals are a universal call to ac tion to end pover t y,protect the planet and improve the lives and prospects of everyone, everywhere. The
17 Goals were adopted by all UN Member States in 2015, as partof the 2030 Agenda
for Sustainable Development which set out a 15-year plan to achieve the Goals.

MEISEI core technologies making history in the ﬁelds of meteorological observation and1938
Establishment
Incorporated withcapital of 300,000
yen in Shimomaruko,
Kamata-ku, Tokyo

1939

MEISEI developed CMO-S48B code
sending type radiosonde, adopting
the then innovative digital method.
This product was delivered to theCentral Meteorological Observatory
and contributed to the establishmentof reputation as MEISEI renowned
with sonde .

1948

MEISEI developed
its ﬁrst radiosonde.
MEISEI received
the ﬁrst order of
1,000 radiosondes.
Three types of radiosonde
were manufactured tomeasure cloud, wind andtemperature & humidity.

01

Japan s ﬁrst electric instrument
launched by a rocket.

Radiosondes were delivered
to the Central MeteorologicalObservatory.

Baby-T Rocket ©JAXA

1952

MEISEI developed and delivered an
FM-FM telemeter transmission system
for the Baby-T Rocket in 1955.
The successful launch made us theJapan s 1st manufacturer ofelectric instruments to beinstalled in rockets.

1955

A weather robot was delivered
to the Central MeteorologicalObservatory.
MEISEI s radio technology realized
unmanned observation of
precipitation, which would replace theconventional manned observation inmeteorological stations, and made it
possible to observe precipitation in
mountainous areas as well.

1964

space development

MEISEI s instruments were
employed by the Winter Partyof the 11th Japanese Antarctic
Research Exploration.
MEISEI s instruments played an importantrole in the observation of Aurora Polaris
by rocket or balloon in the Antarctica from1969 until 1985（for 16 consecutive
years）, when the rocket experiments
ofﬁcially completed, and MEISEI involved
in all Aurora Polaris observations.

1969

Developed a rocketsonde.
MEISEI developed a rocketsonde thatobserved the mesosphere thermosphere（altitude of 60 km above ground level）.
These rocketsondes were launched from themeteorological rocket observation center in
Ayasato, Sanriku-cho（present Ofunato-shi）,
Iwate Prefecture. A total of 1,119 sondes had
been launched by March 2001, when therocket observations were.

1974

Very Long Baseline
Interferometry（VLBI）

Seismic intensity meter was
delivered to JMA.

MEISEI contributed to thedevelopment of VLBI ,which observes radiosources of stars with a radio telescope forultrawide measurement. It is now possible todetect tectonic plate motions in the order of
10cm/year with the VLBI technology, which isgreatly contributing to the prediction ofearthquake occurrence, etc.

MEISEI developed the world ﬁrst seismic intensity meter.
Seismic intensity measurement achieved a great progressfrom the conventional somatosensory method. Seismic
information captured by the Seismic Intensity Meter istransmitted through telecommunication lines, andpromptly delivered to the population through TV andother media thus contributing to the rapid deployment ofemergency and rescue teams in the initial stage ofearthquakes.

1982

1991

1983

AMeDAS（AutomatedMeteorological Data Acquisition
System）was delivered to JMA.

NASA s Space Shuttle
launched with
MEISEI s products.

AMeDAS is a meteorological instrument that
became popular among Japanese people with
its simple and easy-to-understand name. This
unmanned observation system was deployedat 1,300 locations throughout Japan toobserve precipitation, wind direction, windvelocity, temperature and solar radiation.

MEISEI delivered six mounted
devices for Japan s ﬁrst artiﬁcial
aurora experiment（SEPAC）
using a space shuttle.*SEPAC（Space Experiments with
Particle Accelerators）is a joint
US-Japan investigation.

1994

AMOS
（Airport MeteorologicalObserving System）
AMOSs are installed at airports
throughout Japan to observe
weather conditions at the airports
and transmit the data to the Civil
Aviation Bureau and airlines.
Serving an important role in the safe
operation of aircraft.

2000

Tsunami earthquake observation
instruments were delivered to JMA.
In light of the lessons learnt from the disastrous experiences in the
Nihonkai-Chubu Earthquake and Southwest-off Hokkaido Earthquake（Okujiri Earthquake）, MEISEI s tsunami earthquake observation
instruments were deployed at 182 locations throughout Japan in orderto detect earthquakes which may cause Tsunami as early as possible.
These instruments allow around-the-clock observation of earthquakes
throughout Japan and issue tidal wave information withinapproximately three minutes of the occurrence of an earthquake.

What MEISEI should work on
to achieve a sustainable future.
MEISEI's corporate philosophy is "We continuously contribute to
the development of a safe and secure society by creating innovative
products and services utilizing our unique sensing and communication
technologies." Because this philosophy is well aligned with the SDGs,
we believe that we can contribute signiﬁcantly to achieving these
global goals through our operations. As natural disasters and the severityof the damages they cause have been on the increase in recent years,
our weather observation systems such as radiosonde POTEKA ® anddisaster prevention systems such as the seismic intensity meter, QCAST®
can help prevent and mitigate damages from natural disasters. In thearea of space defense, our satellite-mounted instruments are being
utilized for studies on global-scale phenomena using earth observation
satellites as well as to identify damages from natural disasters andenable quick responses. MEISEI can make a variety of contributions to
the achievement of a sustainable future.
