Japan Rain Forest
The Japanese rain forest is in danger
Over half of the world's organisms inhabit the rain forests, which adjust the circulation of the atmosphere, prevent climate changes, preserve water, prevent soil runoff, supply medical ingredients, support the life of indigenous peoples, and give many benefits to humanity. Within this century, more than half of these forests have been lost. Studies by World Resources Institute (WRI) estimate that 20,000,000 hectares are destroyed each year. And, a Study by United Nations Food and Agriculture Organization (FAO) estimates that around 1,300 hectares of tropical forest are destroyed each year.
Ecology, Behaviour and Conservation of Forest Mammals in Yakushima, Japan
Our research in Japan focuses on the behaviour and ecology of mammals in a warm temperate rain forest on the southern island of Yakushima. As well as studying relatively undisturbed areas of forest, we are also investigating the distribution and ecology of mammals in secondary forest and conifer plantations.
Japan extends from Okinawa in subtropical zone to Hokkaido in subpolar zone. Because of sufficient rainfall needed for plants to grow, in correspondence to the plant growth belt of the world, we have, from the south to the north, subtropical rain forest, warmer conifer rorest. In Japan, the forest shares 67% of the land. The forest is composed of 1/3 each of natural forest, copse and artificial forest.
Dynamics and Maintenance Mechanisms of Forest Tree Communities and Ecosystems
I started my research on forest community dynamics in rather simple subalpine fir forests of central Japan, and then extended to more complicated warm-temperate rain forests in southern Japan and tropical rain forests in southeast Asia. It is my purpose, as well as pleasure, to resolve the wonder of complex architecture and diversity in various natural forest systems, now endangered by human exploitation.
Businessman Offers Lessons From Nature
Throughout his 40-year career at Tokyo-based electronics giant Mitsubishi Electric Corp., Takashi Kiuchi has been giving advice to fellow Japanese businessmen to help them become better corporate citizens, overcome their stodgy image and win acceptance in the West.
These days, the 66-year-old former head of Mitsubishi Electric's North American operations is busy sending a new message to Japanese companies:
Save the planet. Kiuchi published a book in January, coauthored with environmental advocate Bill Shireman, "What We Learn in the Rainforest - Business Lessons From Nature." Its message: Companies must abide by the laws of nature - not try to conquer nature - if they hope to thrive.
Top corporate leaders in Japan show their global compassion. Tokai Sangyo, Ltd., offers its authentic and life-saving germanium to the Americans.

Japan Destroys
Japan is destroying the rain forests and the life and culture of the indigenous peoples who reside there!
The Japanese rain forest is in danger
Over half of the world's organisms inhabit the rain forests, which adjust the circulation of the atmosphere, prevent climate changes, preserve water, prevent soil runoff, supply medical ingredients, support the life of indigenous peoples, and give many benefits to humanity. Within this century, more than half of these forests have been lost. Studies by World Resources Institute (WRI) estimate that 20,000,000 hectares are destroyed each year. And, a Study by United Nations Food and Agriculture Organization (FAO) estimates that around 1,300 hectares of tropical forest are destroyed each year.
Destroying the life and culture of indigenous peoples
In Malaysia's Sarawak state, 400,000 hectares of forest are destroyed each year due to commercial logging. Commercial loggers have often cut down the indigenous peoples' ancestral forests without any consent, and even their burial grounds have been destroyed by roadways. The indigenous peoples live off of the forest's plant and animal life, as well as water and fish from the rivers. However, logging has destroyed the forests, polluted the rivers and decreased animal and fish life, making it difficult for the indigenous peoples to sustain their life. Malnutrition, as well as eye and skin disease have troubled indigenous people, pushing them to their emotional limit. The indigenous peoples have sought help from the government, hoping for an end to the destruction, but there has been no improvement. In April of 1987, they protested by blockading logging roads. Over 600 indigenous peoples were arrested in the anti-commercial logging protests, but the roadway blockades continued on.
Japan is eating away the rain forest
Although it has less than 2% of the world's population, Japan imports and uses more rain forest timber than any other country in the world, accounting for more than 40% of the tropical hardwood logs and nearly 30% of the processed tropical timber goods traded internationally.
Throughout the 1960's and 1970's, Japan bought up massive amounts of timber from the Philippines and Indonesia, and later from Sabah in Malaysia. Therefore, Japan is heavily responsible for the massive forest destruction that these countries have suffered. The Philippines became unable to export timber in the 1970's. And although all log exportation was banned in 1985 in Indonesia, it resumed log exportation again in 1998, and again in 1993 in Sabah.
From about 1985 to 1992, Japan was dependent upon the rain forests of Malaysia's Sarawak and Sabah states for 80-90% of its tropical log imports. Roughly half of the wood produced in Sarawak is exported to Japan. The large amount of Japanese timber importation still continues, depending about 60% of logs on Sarawak. Futhermore, Japan presently imports timer from Papua New Guinea and the Solomon Islands. In 1990, ITTO (the International Tropical Timber Organization) warned that unsustainable logging was being carried out in the Sarawak region. However, logging has so far continued to exceed ITTO's recommended limit, and resources are rapidly running out.
In Japan, 50% of the imported timber from tropical rain forests is used in construction, and 30% is used to make furniture. Wood that has taken 100 years to grow is routinely discarded after 2 or 3 uses on the average as forms for molding concrete, and furniture is thrown away every time someone moves. Even most private homes are torn down and rebuilt every 20 years or so.
Japan - Taking care of things too late in the game
80% of Holland's local governments, and several hundred German local governments have set up laws and regulations or made other efforts to stop or control the use of tropical timber. In the United States, San Francisco, Santa Monica, and the state of New York have also established regulations to prohibit the use of tropical timber in public projects. Dordrecht, Holland, has cut off all private trading and sales involving rain forest materials. The European Community and GLOBE (Global Legislators for a Balanced Environment) have passed resolutions to stop importing Sarawak timber.
As of December 1997 in Japan, around 150 local governments had announced policies or made some efforts to reduce tropical timber use. However, their specific means of reducing use have been totally insufficient, and regulations to ban tropical timber use have not been considered.

Ecology, Behaviour and Conservation of Forest Mammals in Yakushima, Japan
Forest ecosystems throughout the world are under increasing pressure from human demands for wood, land and other resources. To minimise the risk of extinction of forest animals it is essential to know what their requirements are. Our research in Japan focuses on the behaviour and ecology of mammals in a warm temperate rain forest on the southern island of Yakushima. As well as studying relatively undisturbed areas of forest, we are also investigating the distribution and ecology of mammals in secondary forest and conifer plantations. Findings will have implications for the conservation of other temperate and subtropical forest ecosystems. |
Background - Yakushima
Yakushima is a mountainous island
of about 500 sq km in the south of Japan. It has
the highest peak in Kyushu (Miyanouradake,
1,935 m), and the great range in altitude
has given rise to a variety of
vegetation types. The three main ones (shown below)
are warm temperate forest from 0 -
800 m, cool temperate forest from 800 - 1,600 m,
and sub-alpine grassland above 1600
m. Research has
concentrated on the warm
temperate rain forest on the
lower slopes. The main field site is on
the west coast of
the island, in an area called
Hanyama. A narrow road passes
through the forest, but
there is no human settlement or
cultivation. This area supports
relatively undisturbed
forest and falls within a new UNESCO
Natural World Heritage Site, one
of only two in
Japan. Additional field sites are
located in secondary forest and conifer plantations in
the same vegetation zone.
Most of my recent research has
been done in collaboration with colleagues at two
institutes of Kyoto University: the
Primate Research
Institute and the
Center for
Ecological Research .
Our work focuses on the
ecology and behaviour of mammals in
the warm temperate rain forest. We
are particularly interested in the
effects of logging,
conifer plantations and forest
regeneration, and the
implications they have for
conservation. Much of our work has
been on an endemic
subspecies of monkey, the
Yakushima macaque (Macaca fuscata
yakui), although we have also
studied sika deer
and wood mice, and work has begun on
insectivorous bats. This collaborative research
has beensupported by grants from the
British Council, Tokyo and
WWF - Japan.
Yakushima - three major
vegetation zones
Recent Research
Macaque diet-
Long-term observations of a small troop of Yakushima macaques
have shown considerable seasonal and
supra-annual variation in the composition
of the diet. Leaves, fruit, seeds
and invertebrates form the major
food at different
times of year. Diversity of diet is
also linked with the
major food types. When fruit is
dominant in the diet, foraging tends
to be concentrated on a few species,
but when
leaves and shoots are the major
foods the monkeys eat a much greater diversity of
species.
Food selection-
Collaborative research with Peter Lucas (University of Hong
Kong),
has investigated physical cues
available to monkeys during food selection of leaves.
Monkeys selectively reject leaf
parts with greater
toughness. In this way they are
selecting the more readily
digestible parts of the leaves,
as we have shown that
toughness is correlated with fibre
content across a range of leaf food species and
parts. This work was extended by
Nicola Parillon for her PhD research at HKU. She
also investigated other physical
cues of food quality, including colour.
Habitat disturbance-
Much of the warm temperate rain forest of Yakushima has
been influenced by logging and
conifer plantations. In 1994-1995 the Yakushima
Wildlife Conservation Project
assessed the effects of
disturbance on the ecology and
distribution of macaques and deer.
Four sites were
simultaneously surveyed by
volunteer field assistants over six
months. The results indicated that habitat
use is
adversely affected by disturbance,
but that mature secondary forest is important
habitat for both monkeys and deer.
Findings were presented at the
International
Primatological Society's
Congress in Madagascar in
August 1998. Subsequent work
has examined the effects of
disturbance on species
composition of secondary forest,
and the influence of forest
disturbance on other forest mammals.

■There are 3 types of forests |
| ●Natural forest: Primeval forest and others without impact from mankind. It is decreasing particularly recently also in Japan. It is the habitat of many kinds and numbers of creatures and plants. People should not add artificiality. ●Copse: The place where some human impacts are given but sapling is not planted Copse has existed since 1,000 years ago and could be seen everywhere in Japan until 30 years ago. People untilized oak grown there for mankind. Nowadays, people do not untilize them and periodical woodcutting is not done any more. habitat environment has changed and those familiar species are disappearing. ●Artificial forest: Japan, in most cases, Scotch pine, Japanese cedar and cypress which are Japan's native trees are planted and the forest floor is habitat of Japan's native species like fern. Lately, because imported lumber is cheap and labor cost is high, there are many forests where matured trees are not cut or maintenance by trimming is not done. No successor is also problematic. |

Research Interest Dynamics and Maintenance Mechanisms of Forest Tree Communities and Ecosystems I started my research on forest community dynamics in rather simple subalpine fir forests of central Japan, and then extended to more complicated warm-temperate rain forests in southern Japan and tropical rain forests in southeast Asia. It is my purpose, as well as pleasure, to resolve the wonder of complex architecture and diversity in various natural forest systems, now endangered by human exploitation. It is necessary for the study of the life of forest tree species to describe not only physiological parameters but also architectural parameters of the organization of trees. The architecture of forest as a cumulative product of individual tree architecture regulates the life of individual trees. I have been analysing the species traits and interspecific interactions between co-occurring tree species in various forests in relation to the vertical structure of forest stand, and the shift of this structure due to the regeneration processes of the overall forest. Recently (1992-; see Nos. 19, 22 & 23 of Publication List), I proposed a new theory that the forest-architecture-dependent competition, particularly for light resource, can promote the stationary architecture of forest and multi-species stable coexistence, which provides a view to combine traditional production ecology, population ecology and community ecology of plants. Undergoing change in forest ecosystems with global environmental change gives a unique lesson to all forest ecologists. I am co-organizing simultaneous projects of forest ecosystem monitoring, as a chairman of the Steering Committee of TEMA ( = 'Global Change Impacts on Terrestrial Ecosystems in Monsoon Asia' as a core research of IGBP-GCTE; link to TEMA home page). My main research sites are the Tomakomai Experimental Forest of Hokkaido University (cool-temperate deciduous forest; link to Tomakomai project page), Yakushima Island (warm-temperate rain forest), the Serimbu Station in West Kalimantan, Indonesia (tropical lowland rain forest), and the Palangka Raya Station in Central Kalimantan, Indonesia (tropical peat swamp forest). Besides these TEMA-relevant field research projects, I have started organizing, since 2000, a TEMA modelling project that focuses upon the functional linkage between leaf/shoot process and individual-tree process, and upon scaling up from individual- tree process to geographic vegetation dynamics. This project is titled (linked to) Ecosystem Architecture Change and is supported by the Frontier Reseach System for Global Change.

BUSINESSMAN OFFERS LESSONS FROM
NATURE |

By Yuri Kageyama
Look people in the eye. Speak up. Do community work. Promote Americans to important positions.
Save the planet. Kiuchi published a book in January,
coauthored with environmental advocate Bill Shireman, "What We Learn in
the Rainforest - Business Lessons From Nature." Its message: Companies
must abide by the laws of nature - not try to conquer nature - if they
hope to thrive. Kiuchi, who also goes by the nickname Tachi, believes the most successful companies of the future will be the ones boasting the best ecological records. "No planet, no business," he says, warning especially of the threat of pollution. Kiuchi didn't always sound more like an activist than an executive. His awakening came about 10 years ago when his company in the United States received thousands of letters protesting the destruction of rain forests by a Mitsubishi group trading company. In the beginning, he was more intent on placating the activists to save his company's reputation. But their enthusiasm and conviction made him realize the easiest option was to join their fight. Kiuchi, now an adviser at Mitsubishi Electric, heads the Tokyo office of a group he helped found called Future 500, which brings together ecologically minded companies and executives. Ford Motor Co. and Nike are among the members. For Kiuchi, who boasts doing 1,600 push-ups a day and often rides his bicycle to work, shattering the stereo-type of the Japanese businessman has been lifetime mission. As Japan's companies grew to global status in the 1980s, they were often criticized as selfish money-grubbers trying to buy up America. In 1997, Kiuchi wrote the book, "Working in America," a manual of dos and don'ts for Japanese businessmen. His advice ranged from the mundane, such as "don't burp in public," to the bit more profound, "Think and act as an individual." He urged Japanese to sing up for volunteer work rather than stay late at the office, and ride on roller coasters rather than play golf. Masayuki Kohama, a former executive at electronics maker Hitachi, who has known Kiuchi for years, recalls how critical it was for Japanese to change their image to avoid being seen as a threat. "We saw our mission as fighting Japan-bashing," Kohama said. "Japanese were perceived as only caring about making money and taking it back home, rather than giving back to the community." As chairman of Mitsubishi Electric America from 1988
to 1997, Kiuchi worked to build the Mitsubishi brand overseas. The
company's U.S. sales climbed 50 percent over those years.
