We study the relationship between crop production and the environment to ensure a stable production of agricultural products.
We also take on the challenge of developing new technologies with the aim of efficiently producing safer and tastier food.
Students learn in depth about sustainable food production, stable food supply, and food production environments, while developing the ability to create new agricultural products.
Through experiments and on-farm training, students learn the theory and practical skills of cultivation in food production, and are educated to develop the ability to solve problems coming along with it.
We educate students to learn deeply about the realities of agriculture in Japan and abroad, as well as advanced agricultural technologies, and to develop human resources who can contribute to advanced agriculture with profound knowledge, skills, and passion.
Students learn solutions to various problems in crop production, including advanced agriculture that enables labor-saving, high-yield, high-quality production.

Around 400 million years ago, green plants appeared on terrestrial land for the first time. Since then, plants have evolved while being exposed to various environmental stresses. Plants might have been accumulating many genetic factors which can sense the fluctuating environments and can optimize their development and growth under environmental stresses. To catch up with climate change, we need to develop crop varieties which can realize the stable high productivity under the advancing global warming. To breed a promising crop variety, we aim to elucidate how plant can respond to environmental stresses.
About 10,000 years ago, human could start agriculture and could achieve the civilization. This achievement was only possible with the help of a few wild plants which was domesticated in response to man's unintentional selection. Now, crops are man's closest partner supporting our food and society. As the climate change is ongoing rapidly, agricultural crops hold the key to the survival of the global population which estimate to be 10 billion in 2050. Let's learn the agricultural science and let's get in close contact with crops. This might be the only way that we could create novel crop varieties that entrust our survival.
Breeding plants that are resistant to environmental changes
Plants are exposed to a variety of environmental changes on a daily basis.
Plants have been able to overcome the changes in their environment by using
various genes. Our goal is to study the functions of the genes that plants have
used to adapt to their environment, and to use these mechanisms to develop
new varieties that can withstand environmental changes.
Food crops, such as cereals, legumes, and root and tuber crops, play an important role in our diet and daily life. We aim to contribute to the food and livelihood of mankind by conducting education and research on the physiological, ecological, and morphological characteristics of these crops, their response mechanisms to the cultivation environment, and the development of production methods and technologies that improve crop productivity and are environmentally friendly.
Let's challenge to cultivate crops incorporated new technologies
We aim to establish crop cultivating methods incorporated new technologies that can improve the productivity and quality of crops, be environmentally friendly, and interesting to the younger generation. We will work to use new ways in the field of crop science, aiming to contribute to the food and lifestyle of mankind.
Scientific studies of food crops on morphology, environmental response, growth, and cultivation
My research activity is focused on analysis of the morphology and the relationships between morphology and functions in food crops, such as yam, eddo, rice, soybean. In addition, I have been studying the effects of environmental factors such as elevated CO2, high and low temperatures, salts, and calcium on the growth, morphology, and physiology in the food crops for contributing to the development of agriculture and society.
We aim to establish the methods for high-yield/quality vegetable production under protected cultivation such as greenhouses and plant factories. In addition, breeding new cultivars for local branding and sustainable cultivation in fruit tree crops are also targeted with based on the knowledge of genetics and molecular biology.
Science of cultivation to promote high yield and quality
High-quality vegetables can’t be harvested with inappropriate cultivation, even if we culture the vegetables with a property good hereditarily. On the contrary, we can cover a fault of vegetable inferior a little hereditarily by culture invention. “The cultivation” is a very important technique in horticultural crop production. There are various kinds of hardly marketable tomato disorders. Now I investigate the cause of tomato disorders and study the cultivation method to avoid that. In addition, I study the feeding method which promote maximum yield with minimum nutrition and the production of root crops such as carrot hydroponically.
Science of fruit season & promotion of local industries
Our tables are colorfully decorated by various fruit crops, which are born in the specified season. My research themes are the regulation of annual lifecycle, environmental effects, and artificial control on the “seasonal fruits”. Furthermore, the creation of noble fruit resources which can be local specialties by taking advantage of new genetic/molecular breeding techniques is also aimed.
The damage caused by pathogens results in the loss of food for 800 million people a year. In our laboratory, we are trying to elucidate how fungal pathogens infect plants and how useful microorganisms prevent fungal pathogens, and to contribute to the development of new technologies of crop protection.
Plant Pathology Saves the World
Plants, like people, get sick by microbial infection. Viruses, bacteria, and fungi are the main pathogens. Among these, filamentous fungi (molds) account for about 80% of plant diseases and cause significant damage to agricultural production. Elucidating the infection mechanism of filamentous fungi will lead to the development of pest control chemicals and disease-resistant plants with less impact on the plant environment. Molecular dissection of the infection mechanism of pathogens can be applied to the development of new plant protection technologies.
We have shown that rice blast, the most important disease of rice, can be controlled by inhibiting the synthesis of melanin pigments. We have also revealed the mechanism by which anthracnose fungi recognize plant surfaces and establish infection by evading plant immune response. In addition, the genome structure of anthracnose fungus, Colletotrichum orbiculare has been clarified, providing the basis for the molecular analysis of pathogenicity.
The interaction between plants and pathogens is explained in an easy-to-understand manner in "Plants at War" (Chapter 2) in Kodansha Bluebacks, edited by the Phytopathological Society of Japan.
Microorganisms that fight pathogens and protect plants from disease
Just as humans get sick, plants also get diseased from attacks by various phytopathogens. Our research activity is focused on the analysis of molecular mechanisms for both "friends" and "foes" microorganisms: how pathogens infect plants and how effective microbes control pathogen. The ultimate aim is to develop new pathogen control techniques and microbial fungicides to protect crops.
Control of insect pests is indispensable for stable production of agricultural products. However, pest control has been overly dependent on insecticides, which often caused concerns about the toxicity of residual chemicals on food as well as the appearance of insecticide-resistant populations. In our laboratory, we study physiological, biochemical, and molecular biological bases of insects’ outstanding ability to adapt to diverse environments. We believe our studies will lead to development of novel insect control measures, because disruption of mechanisms that underlie their adaptability will be fatal to their lives.
Eco-friendly pest control measures
Some insects, so-called agricultural pest insects, are harmful to human beings because they seriously damage production of agricultural products. I study physiology and ecology of pest insects because I believe deep knowledge on their lives will lead to the discovery of their weak points, which can be a novel target for eco-friendly pest control measures.
Insect science of chemical communication
One of the reasons “Insects” has succeeded in adapting to multi-environments on Earth is that insects were able to increase the fitness by the inter- and intra-communication via chemical information from the outside. One of my interests is understanding at the molecular level how the chemicals, such as "odorant" or “tastes”, determine the insect behavior, and exploring the possibility of protecting crops by controlling the behavior of insects by human beings using these chemicals.
Soil is the basis of agricultural production. Depending on the unsuitable field management such as application of chemical fertilizers and compost for the cultivation of crops and water irrigation, and terrible environment due to the extreme weather, soil productivity will be poor. Indeed, the change is hard to see visually. Therefore, in order to properly manage the soil, it is important to establish a simple method for evaluating the physical and chemical properties of the soil and the flora of rhizosphere microorganisms. In our laboratory, after knowing various properties of soil, we will conduct cultivation tests of crops under various managements and proceed with research on the characteristics and management methods of fertile soils.
To realize sustainable agriculture with less environmental load -Promotion of sustainable agriculture using symbiosis of plants and organisms and unused organic matter-
Plants have the ability to synthesize organic substance from inorganic substance, support many life activities on the earth, and have the ability to acquire many inorganic substances from soil and air. In addition, by coexisting with microorganisms, substances that cannot be directly used by plants can be effectively used. One of them is symbiotic nitrogen fixation, which is mainly performed by legumes and rhizobia. Researches to increase crop production by utilizing the affinity between legumes and rhizobia are conducting.
On the other hand, many biomass resources are still wasted in the environment, and their energy and Useful substance s are wasted. For example, the deforestation of neighboring forests is progressing without the maintenance of bamboo forests such as Moso bamboo, and technological development (cutting, transportation, crushing, etc. of bamboo) for effective use of bamboo materials is required. Research for this purpose is proceeding.
Furthermore, it is necessary to promote utilization technology by composting and methane fermentation without incinerating industrial waste and household waste. We are also conducting research to reduce the waste as much as possible and confront the crisis of environmental destruction. To achieve this, it will be necessary to build partnerships with the local community.
Improvement of soil evaluation methods to bring out the best in soil for promotion of agricultural productively and environmental conservation
Soil is the basis of agricultural production; supplies the sufficient water and nutrient for crops as well as keeps the crop bodies and buffers the undesirable condition such as high temperature. Soil is also related to some global environmental problems such as greenhouse gasses emission. Therefore, field management based on suitable evaluation of soil condition can contribute to promotion of agricultural productively and environmental conservation. My research mainly focuses on the labile organic matters since they affect the various soil properties. The research field is not only agricultural land but also other ecosystems.
Research on plant sensing for infection-related morphogenesis of phytopathogenic fungi
Plants get sick by fungi, viruses and bacteria. Fungi recognize various environmental cues and start invasion in response to plant surface signals. My research focuses on the molecular mechanisms how fungal pathogen senses and responses to plant signals.
Tropical crops that support our lives
What comes to mind when you think of foods cultivated in tropic region? Tropical fruits as durian and mango, long grain rice and coffee attracts us by its flavor and bitter taste… But also a large portion of indispensable items such as palm oil, sugar, cassava starch are imported. Improvement and stabilization of agriculture in import source regions has two meanings, international cooperation and stable food supply for Japan heavily depending on foreign countries. In addition, research on tropical regions and their agriculture will help prepare for environmental changes caused by global warming. Thus, I have a great interest in utilization and cultivation of crops including tropic origins.
The program aims to educate specialists with the ability to scientifically elucidate the relationship between food and the biological and non-biological environment surrounding them, and to disseminate and provide guidance on agricultural production technology in the “field” of agricultural production, including crop improvement, development of optimal cultivation methods and new production technology.
