Fluvial geomorphology, Quaternary Geology, Tephrochronology2) Overview of Research Activities
To prospect the futuristic view of environmental changes, our laboratory investigates thehistory and process of surface landform/geological development during the Quaternary period.
The followings are some topics of our studies.
1. Reconstruction of geomorphological/geological phenomena during the Quaternary (thelast 2–3 million years) with accuracies of 105–101 years
2. Study on volcanic products (tephra) and explosive eruption history in and around theJapanese Islands
3. Investigation on production–transport–depositional processes of sedimentary particles
4. Study on coastal–deep marine sediment for reconstruction of natural hazard history andinfluence of human activity to natural environment
5. Reconstructionofearthquake

2) Overview of Research Activities
Our laboratory investigates climate system on the earth in various temporal-spatial scales. In
particular, we focus on climate changes due both to natural and anthropogenic causes, forexample, processes of heat island and heavy rainfall events over and around urban regions, andinfluences of land-use changes and deforestation on regional climates. We also investigate
10

diurnal, intra-seasonal, and inter-annual variabilities and long-term changes of climate, inparticular, rainfall activities in the Asian monsoon region, and influences of global warming on
regional climates (future projection).
We apply three major methods, observation (monitoring), data-analysis of various global andregional datasets, and numerical modeling for investigating above-mentioned topics.
1)

Climate changes and climate variability over Japan and around the world

2)

Variability and seasonal changes of regional climate over Asian monsoon region

3)

Observational study on formation processes of urban heat island, detailed structure ofurban boundary layer, and elucidation of urban effects on short duration intense rainfall

4)

Impacts of land-surface conditions and changes on cloud and precipitation activities, inparticular, in the tropics

5)

Reconstruction of past climate during the historical period in Japan and in East Asia

Associate Professor : Masayuki KAWAHIGASHI
Soil Ecology, Environmental Chemistry, Material Cycling in Ecosystems2) Overview of Research Activities
This research unit focuses on the relations between human and natural environment. For
understanding processes enacted upon environment in local and regional scales, we try tointegrate subdivisions of both physical and human geography together with interdisciplinary
aspects of environmental sciences, such as botanical science, forest ecology, zoology, soil
science, landscape design, political ecology, folklore, anthropology and so on. Researchmethods are in primary based on fieldworks, including weather observation, land survey, soil
and vegetation surveys, and interview survey and in participative on laboratory analyses on
soil-water analyses, and interpretations of aerial photo and satellite imagery as well.
1. Development of survey methods for evaluation of soils in urban area
2. Characterization of sclerotium grains and their function in forest soil ecosystem
3. Geoarcheological study of ancient water environment in Kharga, Western Desert, Egypt
4. Environmental dynamics study of watershed area of Small Water Impounding Project dam
in central Luzon, Philippines
5. Influence of anthropic pressure in a river basin on downstream water environment
6. Evaluation of forest fire impact on soil, vegetation and landform in terrestrial ecosystems
7. Study for elemental dynamics in urban ecosystems
8. Soil carbon sequestration from the point of view of soil parent material203) List of Research Activities in FY2020

This laboratory is mainly going to study the natural environment as a whole which iscomposed of geomorphology, climate, hydrology, vegetation, and so on. Concretely, deductive
approach and inductive approach are combined for conducting studies. The former approach isgoing to explain results from causes by physical lows such as mass balance, energy balance,
equation of motion, and so on. The latter approach is going to explain facts demonstratively
based on field surveys and in situ observations. Therefore, collection of quantitative data, digital
mapping, statistical analyses, numerical modeling, and GIS (Geographical Information
Systems) are main methods used in this laboratory.
The main study themes in this laboratory are listed as follows.
1. Energy and water cycle in the atmosphere and hydrosphere
2. Capturing snow distribution and snow water resources, along with snowmelt-runoff basedon remote sensing techniques and field surveys
3. Quantitative evaluation of spectral reflectance characteristics of coniferous forests and theirleaf area indices4. Water environment around Mt. Aso and Tokyo Metropolis
5. Numerical simulation of urban climate and local wind
6. Capturing surface conditions of cities using GIS
7. Monitoring and modeling natural environment and natural hazards
25

8. Quantitative evaluation of geographical phenomena in Tokyo in the modern era

2) Overview of Research Activities
This research unit specializes in human geography, with special emphasis on the city and its
environs. Our research interests center on the structural explanation of the relationshipbetween human activities and geographic environment by employing approaches of social
sciences and humanities. Methodologically, the emphasis lies largely on positivistic (viz.,quantitative or mathematical); fieldwork is also encouraged. The research interests coverquantitative, socioeconomic, urban and behavioral geography. The main themes of our current
research are as follows:
1. Mathematical modeling of human geographic phenomena
1) Location of economic activities
2) Human migration, commodity flow, and spatial diffusion of information
3) Mental map and spatial behavior
4) Time geography
2. Regional analysis of human geographic phenomena
1) Relationship between human activities and geographic environment2) Land use change in the city and its suburbs3) Spatial organization of the society4) Transformation of human activities brought about by environmental change
