We have to evaluate the occurrence prediction and disaster occurrence risk of landslides from inspection data. We analyze the trend of the past of the disaster, to assess whether the “when” “where” landslide disaster occurs, we are working to hazard maps.
These results are considered useful in a safe life.

Our laboratory conducts petrological research on granites widely distributed in southwestern Japan, using fieldwork as the main means of study. In addition to granite, we also reserch to tuffs and basic igneous rocks. Informatics technics, such as GIS are used in study. In addition, granite weathering, landform formation, stone material utilization, etc. are being studied.

I study influences of meteorological and climatological conditions on human life and agriculture activities.

I am inerested in researches of local meteorology such as wind, temperature, and humidity, and biometeorology such as heat or cold stresses of human, animal, and plant.

My researches have been extended by using both a meteorological observation and numerical simulation for various regions in Japan.

How the earth and planets are formed ?
I’m trying to answer this question by observing protoplanetary disks, which is the on-going planet forming site around young stars. Current large telescopes such as Subaru telescope allow us to reaveal the detailed signature of the planet formation process in the protoplanetary disks.
In addition, I’m also involved with the new development of the astronomical instrument and methed.

I am actively involved in paleontological excavations spanning Mongolia, Kenya, and northern Okayama Prefecture, while simultaneously conducting meticulous paleoenvironmental reconstructions based on robust geological investigations. Moreover, my endeavors extend to the comprehensive reconstruction of the entire ecological framework of the relevant time periods, encompassing small vertebrates, insects, and invertebrates, achieved through the discernment of the intricate interconnections between fossils and their corresponding stratigraphic contexts. Furthermore, our team enthusiastically engages in lifelong learning endeavors, exemplified by organizing exhibitions, workshops, and lectures that showcase esteemed fossil specimens.

How can the population ｓustain in wetlands where the environment spatially and temporally fluctuates? We study the ecology of amphibians and reptiles in wetlands as target areas. Also, we study the anthropogenic impacts, such as paddy improvement and abandonment, on those populations from the viewpoint of conservation biology as well as ecology and evolution.

My research is focused on the diversification and evolution of flowering plants, mainly Cyperaceae (sedges family), ranged from Japan to the Himalayas through China. Cyperaceae is one of the most diversified group in flowering plants, and is suitable for studies of plant systematic and evolution. I have conducted taxonomic, phylogenetic and cytological studies of Cyperaceae.

Based on fieldwork in flood zones from the Himalayan highlands above 4,000 meters to the zero-meter flood zones, we are trying to elucidate the actual disaster conditions and land development processes in each region. In contrasting between regions, we emphasize primary data and attempt to relativize the issues.

Bone histology is the study of bone function and growth by sectioning bones into thin slices to visualize internal tissues. This technique has proven instrumental in uncovering the physiology and ecology of extinct animals, providing insights into their growth rate, age, metabolism, and degree of aquatic adaptation — factors that were previously challenging to reconstruct. My research focuses on employing bone histology to explore the life and adaptive processes of large vertebrates, such as dinosaurs and mammals. Specifically, I aim to uncover what factors influenced these creatures to evolve into giants or diminutive forms and how terrestrial vertebrates altered their physiology and bone structure to successfully readapt to aquatic environments.

I have interests in parental care and sexual conflicts over reproduction in teleost fishes. My goal is to understand social relationship among individuals by approaching the field researches and observations in lab conditions, from evorutionary views. In the resent years, I also conduct some field works to examine a composition of food-webs in aquatic ecosystem and evaluate the relationships between biodiversity of aquatic animals (e.g. dragonflies) and their local and landscape habitats.

The radius of Earth is 6371 km, whereas the deepest borehole ever drilled reached only 12 km (0.2% of Earth radius) into Earth. It can be said that Earth’s deep interior is the place further than the universe. We analyze the seismic wave and explore the deep interior of the earth which can’t be seen directly. By analyzing propagation of the seismic wave, we investigate the temperature and the existence of magma and/or fluid, and we consider the dynamics of the Earth.

The Upper Paleolithic age of the Japanese archipelago is represented as blade based industries, and there are close relationships between blade production techniques and the beginning of the Upper Paleolithic age. Furthermore, the “knife-shaped tool” is one of the typical formal tool types of the blade industry in the Japanese archipelago. For the Initial Upper Paleolithic period when the blade technology was not yet fully established, a set of technique was also confirmed which utilized flakes and vertical elongated flakes. Although various chronological hypotheses of the EUP were so far presented, they have not been unified yet.
I rethink the Early Upper Paleolithic industries in the Japanese Archipelago and East Asia throught the method of Usewear analysis and Traceology.

Animal bones typically contain growth marks, similar to those of tree rings. Previous studies have utilized these marks to reconstruct the growth of extinct animals, especially dinosaurs, and further investigate their physiology and ecology. Using specimens and data that I have collected through fieldwork and museum visits all over the world, I hope to contribute to our understanding of the link between life histories of fossil animals and macroevolutionary patterns.

My research is a practical study based on the reality of children’s thinking and expression as seen from the school site. Arts and crafts is a subject that deepens awareness of diversity.　I will develop teaching materials that aim to foster diverse ways of seeing and thinking and the acquisition of expressive skills. I will propose teaching methods that aim to improve children’s ability to think and create figuratively through learning from each other.

I study the deviation and the comformity in the human’s socialization process through inventory survey and interviews about delinquency and family relations in combination. Now I am interested in a correlation between spur-of-the-moment-act and emotion dysregulation. Furthermore, I am deeply interested in practical problems such as the way of student guidance, the vocational counseling (class instruction, tutorial) , a social hierarchy and the inequity of the learning opportunity.

I am mainly researching the development of science teaching materials that can be used in educational sites. In elementary and junior high school science, especially in elementary school science experiments, most of them are qualitative experiments. For example, when investigating the properties of things that are “invisible” to the human eye, such as light and magnetic force, we use relative terms such as “bright” and “strong.” Even in qualitative experiments that rely on bodily sensations, we can “see” the nature of things. However, if we can compare this experience with numerical values such as “how bright” and “how strong”, we will be able to “see more” what we “see” until now. Experiments that compare numerically like this are called quantitative experiments. When we can “visualize” the properties of things with these educational materials, we are sure that the observer’s eyes will have a higher resolution and be moved by the wonder and charm of the natural world. We are conducting research on the development of teaching materials that can be “more visualized” in various fields of science education.

It is said that physical education classes are relatively popular with children and students, and that they are highly independent in these classes.It is true that this has been supported by the diligent research of teaching materials by in-service teachers and the development of teaching methods.
However, in the in-service teachers differentiation according to individuals and groups is required because.However, the development of teaching materials and the choice of teaching methods are becoming half-implicit knowledge.I am trying to systematize the enormous teaching methods of in-service teachers that have been cultivated so far.As such, I hope to make teacher behavior explicit knowledge.

This study aims to cultivate management curriculum abilities though the Social Teacher Lesson．The study consisted of the following three steps.　First I encouraged the student to reflect on their own perceptions on the meanings of learning．Second, their own views of social studies and theories of teaching were relativized by learning about multiple theories of teaching with different goals. Finally I made them understand the importance of engaging in teaching materials study and content construction in accordance with subject objectives, using as material subjects．

Music instruction is conducted not only through words, but also through various non-verbal means of expression, such as eye contact, gestures, and facial expressions. We are collecting and studying objective data on what music teachers look at and how they use their bodies in response to what situations, using eye-gaze measurement devices, motion capture, etc. We are also collecting data on the actual status of music teachers’ nonverbal communication by comparing these data with the results of interviews with teachers. By comparing these data with the results of interviews with teachers, we aim to elucidate the actual state of nonverbal communication among music teachers.
We are also conducting research on the relationship between music and physical expression.

“Home economics” in school education aims to improve the skill of homemaking through the velationships between oneself and their family, their consumption habit, their eating habit, their dwelling life, their clothing life and so on.
“Home economics” is concerned with not only our claily life but some subjects life social studies and science. Moreover it’s very important to reflect on your home life so far.
I investigate how “Home economics” should be and I design exciting, satisfactory and practical classes.
