Introduction
The most important mission of the Agricultural
Extension Service is to transmit and spread
new agricultural technological methods to
farmers. These new technologies are usually
developed by agricultural research institutes.
To get the research results is one of the
most important functions of the extension
service.
In Japan, there are many kind of National
Research Institutes and Prefectural Research
Institutes. Each of them has its own functions
which is related to agricultural production.
A present research system and the organization
of the national government and the prefectural
government systems are introduced.

3) The main objectives of research activities
for Agriculture, Forestry, and Fisheries
(Jul.1996)
(1) Strengthening of the Structure of Agriculture,
Forestry and Fisheries in Japan
In order to strengthen the structure of agriculture,
forestry and fisheries in Japan, it is essential
to increase productivity, improve product
quality, secure more comfortable labor conditions
and to promote environmentally-sound agriculture.
For long-term expansion, both at the national
and regional levels, advanced basic research
to upgrade production technology for agriculture,
forestry and fisheries should be developed,
along with innovative technological systems
which can be transferred to the production
sites.
(2) Development and Utilization of Bio-functions
for Generating New Industries
In order to generate new industries beyond
the current limits of agriculture, forestry
and fisheries, it is important to conduct
basic studies. These studies include the
development of food products with new functions,
development of new bio-materials and promotion
of bio-remediation technology through the
elucidation of various bio-functions.
(3) Upgrading of Processing and Distribution
Systems for Agriculture, Forestry and Fisheries
Products
To meet the growing diversification and sophistication
of consumers' needs, it is important to provide
consumers with safe, wholesome and value-added
food products.
To achieve these objectives, it is essential
to upgrade processing distribution and quality
evaluation technology, as well as carry out
studies for developing a more efficient marketing
system.
(4) Revitalization of Rural Communities and
Enhancement of Multiple Functions of Agriculture,
Forestry and fisheries
Rural and fisheries communities need to be
reorganized and become more attractive to
urban residents.
Therefore, it is necessary to carry out research
for the development of technology, to upgrade
the infrastructure in order to improve the
production and living environment, to draft
comprehensive regional plans, and to develop
techniques for the promotion of regional
products and mixed farming systems, as well
as to enhance the multiple functions of agriculture,
forestry and fisheries in these communities.
(5) Conservation of the Environment and Appropriate
Management of National Research for Sustainable
Development Mankind
In order to promote sustainable development
mankind in harmony with the natural environment,
basic and applied research should be carried
out to develop techniques for environmental
conservation of oceanic and forest resources
as well as appropriate management of biological
resources. In addition to this, environmental
issues on a global scale should be addressed.
(6) Contribution to the Development of Agriculture,
Forestry and Fisheries from and International
Perspective
Since it is anticipated that the population
in the developing countries will continue
to increase rapidly, it is important to undertake
cooperative research projects.
These projects should kind solutions to
stabilize the supply and demand of food commodities
to contribute to the sustainable development
of agriculture, forestry and fisheries on
a global scale.
(7) Development of Cross-cutting Basic Research
Strategies
In order to promote basic as well as efficient
applied research in the field of agriculture,
forestry and fisheries, cross-cutting basic
research strategies need to be improved such
as, upgrading information sciences and the
development of new technology for gene manipulation,
sensing, as well as the conservation and
evaluation of genetic resources.
4) Types of Research
(1) Ordinary Research
Research which is set up by each institute
without cooperation from other institutes
(2) Project Research
A research which is set up by AFF Research
Council in cooperation with many research
institutes.
(3) Designated Research
Research which is entrusted to prefectural
research institutes
(4) International Research
Joint research project with developing
countries

4) Personnel exchange
5) An example of a research-extension linkage
system in Fukui prefecture
In Fukui prefecture, the Rice Growth Diagnosis
and Forecast System has been in operation
since 1991. The purposes of this system
are: a practice of effective rice cultivation
and a stable production of superior quality
rice by means of accurate diagnosis and forecasts.
Before we made up this system, diagnosis
of growth and forecast of the main rice growth
periods were conducted in each area or extension
center. This system covers all of the prefectural
area now.
This system is mainly managed by extension
workers, SMSs, researchers and government
staff.
(1) Diagnosis and forecasts of the growth
of paddy rice by mean of personal computers
- Summary and diagnosis of the growth information
is based on the investigative data which
is collected by extension workers every week.
The investigation fields are the 47 places
and each field has 10 years of cumulative
data.
- Forecast of the panicle formation stage
and the heading stage is based on the DVS
system which are calculate using a following
factors: transplanting date, a leaf age,
daily air temperature and day length.
- Forecast of the outbreak of rice blast
is based on the BLASTAM system which is calculated
from meteorological data such as temperature,
precipitation, duration of sunshine and wind
every hour.
(2) Preparation of the technical countermeasure
leaflets are based on growth diagnosis results
- The applicable technical countermeasures
are discussed by SMSs, researchers, agricultural
cooperative staff and prefectural government
staff. The countermeasures are based on
the results obtained from the discussion
carried out on the growth information, weather
information, growth forecast, plague and
disease outbreak forecast, etc., and the
relevant guidance leaflets are prepared.
(3) Transmission of the technical countermeasure
to farmers
- Each extension center or local cooperative
office gets the countermeasures from the
network system following the day of the investigation.
- Each local organization, such as extension
centers, add their own local countermeasures
and inform farmers of the countermeasures.
4. Classification of nations according to
linkage type
1) Theoretical framework for types of linkages
2) Promotion of linkage between research
and extension administration for improving
an agricultural production
(1) Improvement of extension activities
method.
Trying a direct approach to the leader of
farmers and informal farmers' groups instead
of the administrative route
(2) Reform the committee system
To reflect the actual condition of farming,
cementing the relationship between committees
and extension workers or farmers
(3) Training of researchers and extension
workers
Systematic training is essential for their
competence as a researchers or as a extension
workers
(4) Establishment of local research institutes
Establishment of research institutes in
every state and specialization of these
institute requires a lot of time and money.
(5) Promotion of personnel exchange between
research and extension
The improvement of the educational background
of the extension workers is essential to
promote personnel exchange.
