The University of Tokyo Forests (UTF) of the University of Tokyo was established in 1894 to contribute to forest science and forestry education and research in Japan.
It owns seven university forests in various parts of Japan. Research in the UTF is carried not only out to elucidate the mechanisms of forest ecosystems and public functions, but also to evaluate the social and cultural relationships between forests and human beings.
Many research projects are underway to solve global issues such as climate change and forest degradation through collaboration with forest scientists all around the world.
The education program is designed for graduate students in master’s and doctoral courses. We will educate the next generation of leaders in forest management locally, nationally and globally.
UTF is inviting students who are eager to perform leading research projects to join us.

Laboratory of Forest Ecosystem
We are conducting research related to the dynamics of forest ecosystems and mechanisms to sustain biodiversity. Research topics include interactions among organisms, genetic structures, adaptation to the environment, impacts of climate change and wildlife management, which have been studied at the individual, population and community levels for a variety of forest dwelling organisms as well as the forest itself.
  ●Spatial and temporal population dynamics of forest defoliating insects and their biological interactions
  ●Influences of global warming on forest insects
  ●Wood boring insects and forest decline
  ●Genetic dissection of local adaptations in forest trees
  ●Response against heat stress of boreal trees in the age of global warming
  ●Ecological consequences of deer herbivory on biodiversity and biological interactions in forest ecosystems
  ●Ecosystem functioning of rhizosphere organisms and microbes in plant-soil feedback systems
  ●Molecular mechanisms of mass flowering in bamboo
  ●Expression analysis of flowering genes in Abies sachalinensis
  ●Development of DNA markers for putative hybrid species detection in Japanese dwarf bamboo
  ●Long term dynamics and diversity of forests
  ●Stand development of forests that have been disturbed by a super typhoon
  ●Stand structure and dynamics of wave-regenerated forests
  ●Ecology and behavior of forest dwelling bats

Laboratory of Forest Functional Biology
We focus on the functional aspects of forest organisms through physiological, chemical, structural and genetic research at the individual, organ, tissue, cell and gene levels, and investigation of the compounds expressed against various biotic and abiotic agents in diverse forest environments. We are attempting to reveal the mechanisms of interaction among these agents. Such information can be applied to protection, improvement and sustainable use strategies for forests. Our research topics include how trees respond to pathogen attacks and how the environment and symbiotic microorganisms affect the defense systems of trees. These topics are studied in terms of the interactions between trees and other forest organisms, particularly microorganisms. With respect to environmental stress, the tolerance of trees to heavy metals and water stress has been evaluated. This information can be used for the reforestation of deserted mines contaminated with heavy metals as well as the improvement of tree health in urban areas.
  ●Defense responses and resistance mechanisms of trees against pathogens and their application to forest health.
  ●Mechanism of the blockage of water conduction in trees with wilt disease and determinants of pathogenesis
  ●Process of deserted mine reforestation and the role of symbiotic microorganisms, and improvements to reforestation
  ●Inhibiting factors of tree regeneration and improvement of regeneration
  ●Relationship between responses of trees against biotic/abiotic stress and gene expression/metabolites
  ●Mechanisms of useful metabolites formation of woody plants and their effective production

Laboratory of Forest and Human Society Relationship
We study preferable relationships between the forest ecosystem and human society using various methods based on natural science, social science and the humanities. From the holistic viewpoint that forest ecosystems and human society operate as one system, we collect and analyze various information from the field so that our society can manage its forests sustainably. We aim to explore the general relationships between forest ecosystems and human society not only by developing techniques for the collection and dissemination of information from the forest, but also by examining the application of this information to social and economic systems.
  ●Survey methods and use of hardwood forests for energy and high-value usage
  ●Development and evaluation of forest environmental education programs
  ●Understanding the culture within forest ecosystems and its processes
  ●Labor productivity of forestry with the effects of the declining and aging population causing labor shortages
  ●Relationship between health promotion and healthcare resources in rural areas
  ●Research on the growth and future transition of old-age planted forests using scarce data
  ●Dendro-ecological considerations for changes in forest use in Japan
  ●Analysis of forest dynamics using a dendro-ecological approach and proposals for forest management
  ●Development of a forest utilization system based on multifaceted analysis of the relationships between forest ecosystems and
   human society
  ●Construction of new relationships between forests and society through education and recreation activities

Laboratory of Forest and Water Resources Management
We work on theories and methods that are practically useful for the comprehensive and sustainable management of forest and water resources at the watershed scale. Fundamental studies consist of hydrological studies identifying water and nutrient cycles in various forested watersheds and long-term and large-scale ecosystem monitoring in order to demonstrate the structure and dynamics of managed forests. We further aim to propose optimum methods that can be applied to the management of forested watersheds based on the evaluation of watershed functions that are beneficial to the public both locally (e.g. ecosystem services to the residents) and globally (e.g. greenhouse gas sequestration). Our reported research results include: 1) Processes of water and nutrient cycles and mass movement during forest restoration; 2) Dominant factors affecting rain runoff characteristics in various mountainous watersheds at different spatial scales; 3) Forest resource management planning using GIS; and 4) Spatial information management at the University of Tokyo Forests. At present, we are pursuing the following research topics:
  ●Effects of climate change and human management on ecosystem services of forested watersheds
  ●Analysis of habitats of trees in suburban forests in relation to hydro-meteorological variables
  ●Evaluation of multiple functions of forested watersheds using monitoring indices
  ●Establishment of a sustainable forest management system based on long-term and large-scale monitoring information
