Natural Water Sanctuaries (Water Resource Cultivation/ Preserving Biodiversity)

The Suntory Group has been conducting Natural Water Sanctuary Projects in order to preserve water resources and biodiversity.

Natural Water Sanctuary Projects

The Suntory Group uses a large amount of groundwater in the manufacturing of its products. To maintain the sustainability of that groundwater, from 2003 we have been signing medium- to long-term contracts that last decades with governmental bodies and with forest owners in each region where we operate, and have been conducting activities aimed at preserving and recharging water through our Suntory Natural Water Sanctuaries.
Suntory strives to conserve forests that protect the future of water and life on Earth; to this end, we engage in Natural Water Sanctuary projects that also contribute to the long-term sustainability of our core businesses, including soft drinks and alcoholic beverages. In our forest conservation activities, we carry out thorough scientific investigation and research that provide the basis for the formulation of science-based plans and targets most suitable for each specific location. Furthermore, to make these activities even more sustainable, we support human resources development and environmental education of next generations that will inherit technological know-how and knowledge towards the overall goal to improve water cultivation and to enhace biodiversity preservation.

From "Water for Suntory" to "Water for the Society"

To support Natural Water Sanctuaries, the Suntory Institute for Water Science first of all performs the analysis of water composition, as well as the survey of landscape, subsurface geology, the factory and wells in the surrounding areas and other parameters to determine the groundwater cultivation area used for the plant. We calculate the area of forest considering the characteristics of the land, and then enter into forest development contracts with the cooperation of forest owners. The term of the contract is set to more than 30 years enabling us to engage in activities from a mid- to long-term perspective.
In 2009, we set a mid-term goal of expanding forest area required to nurture groundwater so as to recharge the amount used at Suntory production facilities in Japan, and in 2013, we successfully expanded protected forests area to about 7,600ha, which exceeded our goal. In 2014, we set a new target to nurture double the amount of groundwater pumped up in all of our factories in Japan by 2020 for use not only by Suntory but also by society. As of March 2018, there are 20 Suntory Natural Water Sanctuaries across 14 prefectures in Japan with a total of approximately 9,000ha, managed according to the characteristics of each forest.

Forest Cultivation Forecasting Several Decades to Several Hundred Years -- Natural Water Sanctuary's Ideal Form

Approximately 70% of Japan’s land mass is said to be covered with forests, but not all forests are healthy. Natural Water Sanctuaries designated by Suntory go further than reducing the impact on our business activities to contribute to conservation of biodiversity by advancing initiatives to revitalizes forests that have been devastated. Suntory established the following objectives for the Natural Water Sanctuaries and continues to work with local communities in a variety of ways.

<Natural Water Sanctuary Development Targets>

  1. 1.
    Forests with a great capacity for cultivating water resources
    Forest ground gently receives rain that gradually penetrates the ground and purifies the water physically, chemically and microbiologically. Forests rich in various trees and grass nurture and protect such soil.
  2. 2.
    Forests rich in biodiversity
    Forest with diverse plants nurtures an environment that is home to diverse animals. Animals and plants in the forest are a barometer of its biodiversity and health.
  3. 3.
    Forests able to withstand flooding and landslides
    Trees in the forest have roots that stretch straight into the ground playing the role of a stake and wide thin roots stretching outward that play the role of a net and grasp the ground. Having a variety of trees creates forests that do not allow movement of soil and are therefore resistant to disasters.
  4. 4.
    Forests with great CO2 absorption capabilities
    Plants absorb CO2 and create oxygen but slow growing trees are said not to absorb much CO2. We appropriately manage the forest with the aim of nurturing a forest that has high growth rate trees that easily absorb CO2.
  5. 5.
    Beautiful forests where visitors can encounter nature in all its abundance
    We create a space where people can gather and get in touch with animals and plants and also use it as a place for environmental education for children.

Sustainable Forest Conservation Activities for the Next Generation

Continuous preservation activities are required to preserve the health of Natural Water Sanctuaries. Natural Water Sanctuaries throughout Japan each have different characteristics and issues and thus, we engage in activities that consider 50 and 100 years ahead based on the RPDCA cycle that includes scientifically-based survey and research (Research), creation of a vision (development plan) suited to each forest (Plan), management (Do), verification of results(Check), consideration of measures for improvement (Action).

[R in RPDCA] Scientifically-based Surveys and Research

It is important to understand the characteristics of the region to make the Natural Water Sanctuary an ideal forest. In doing so, research and advice of experts in various fields such as geology, soil, vegetation, erosion control, hydrology, vegetation, birds, insects and microorganisms is indispensable. Thus, we are engaging in cooperative research using the latest technology with universities and research institutes as well as working in forest development while continuing various activities in cooperation with governments, forest owners, local residents, companies and volunteers.

[R in RPDCA] Use of Aerial Laser Measurements

In surveys and development of the Natural Water Sanctuaries, we are using aerial laser measurement, which is the latest geomorphic analysis technology, to increase accuracy and efficiency.
We are able to measure three-dimensional geomorphic data in minute detail by using helicopters and UAV (often called drones) in addition to Cessna planes that are able to fly along complex land formations. We are able to understand topographical information that cannot be seen on conventional topographic maps and aerial photographs to fully grasp the topology even in steep areas that are difficult to reach.
Through the use of this type of data, we heighten the accuracy of various surveys and analyses in addition to making research and development activities more efficient.

[P in RPDCA] Proposals for Long-term Activity Development Plans (Vision)

We propose and establish mid- to long-term vision and development plan considering characteristic and issues of each forest based on the results of surveys from various perspectives.

  • Creating development plant most suitable for each area

  • Zoning

Video: Zoning

[D in RPDCA] Development activities by professionals

Each forest is managed according to their own development activities (initiatives) based on the development plans. Forest management covers a wide range of tasks such as tree thinning, clearing underbrush and making strip roads. We also share the activity policy with local forestry cooperatives, foresters and commissions to utilize the required high-level technology as well as properly conduct forest management in the set period of time.

- Tree thinning and pruning

Appropriate tree thinning and pruning is done in artificial forests of cedar and cypress so light can get through the forest. Through this, various plants and broad-leaf trees can grow to recover rich vegetation. The debris from tree thinning work is valued and used as a by-product through means such as in soil retainers in forests or as timber transported from cultivated forests*.

Guidance toward healthy forests

- Making Strip Roads

Strip roads and foot ways are necessary in surveying and developing the forest. We are able to execute activities with even greater accuracy by not only transporting timber out on these roads but also changing the frequency devices are used for surveying and forest management as well as actual exploration. Natural Water Sanctuaries promote roads that are kind to nature and that are long lasting so that these routes become one with the surrounding environment. Roads that blend in with nature are not only used by people but also by various animals such as for a hunting ground for birds of prey like eagles and hawks, functioning as part of the habitat for animals living in the forest.

Building environmentally-friendly strip roads

- Measures against harmful animals

The damage caused by an overpopulation of deer around Japan trampling the grass and eating all of the bark is vast. We trim trees to let light into the forest, but the vegetation and low hanging leaves that are all eaten by the deer makes biodiversity scarce and also causes soil erosion and landslides. As some of the measures to address this issue in the Natural Water Sanctuaries, we have installed protective fences around vegetation to keep the deer out as well as protected the surface soil by growing vegetation and small trees the deer do not like to conserve the biodiversity and prevent soil erosion. We will also search for ways to protect the quality of plants more efficiently by conducting behavioral studies of the deer.

Measures against harmful animals

- Making seedlings and planting trees

In cases tree planting is necessary as a measure against grazing deer, plants from different land may break the ecosystem so we take care to use seedlings from seeds collected from the local area with respect for the region.

  • Seeds harvest locally

[CA in RPDCA] Monitoring and Subsequent Surveys

We are monitoring and evaluating whether the development we have introduced is properly contributing to the conservation of the forest. We confirm whether changes have occurred and review plans as necessary especially in terms of groundwater, soil, birds, and vegetation. We need to be able to flexibly respond to these types of natural changes to engage in sustainable activities.

Supporting the Education of Human Resources Who Work in Forest Development

The same activities cannot stay limited to the Natural Water Sanctuaries, but need to spread throughout Japan to revitalize forests around the nation. Therefore, Suntory widely publishes the results of its research activities related to the Natural Water Sanctuaries. In addition, we are conducting courses, practical training and Natural Water Sanctuary forums to develop human resources in the field of Natural Water Sanctuaries so that we may communicate the techniques and know-how necessary to develop forests such as more efficient quality development and road building techniques.

  • Road building workshop

  • Passing along efficient and
    effective tree trimming techniques

Preservation of Biodiversity

The ecosystem of the forest forms a pyramid supported by soil and plants at its foundation. A healthy ecological pyramid needs a wealth of diversity in the soil and vegetation to survive.
The business activities of the Suntory Group that use water and agricultural goods as their primary ingredients is supported by this healthy ecosystem. The Suntory Group recognizes the protection of this ecosystem as its inherent duty and it is expanding a wide range of activities to preserve the natural environment that supports biodiversity.
In addition to the Natural Water Sanctuaries that act as water resource cultivation areas for our plants in Japan, Suntory is also engaged in risk evaluation and strategic management through continuous monitoring of the ecosystem in our existing businesses. We designated water resource cultivation areas at our plants even when moving forward with new businesses and comprehensively evaluate risks with the cooperation of experts in a wide range of fields as done with other Natural Water Sanctuaries. We manage each of these areas based on a medium- to long-term visions.

In the forest for the water resource cultivation area in our Aso Natural Water Sanctuary for example, we maintain, test, and survey the forest with the aim to enhance the recovery and conservation of the biodiversity as well as the water resource cultivation function, such as experimenting with tree thinning to create hunting grounds for birds of prey. We aim to nurture a richer ecosystem throughout the entire river basin by entering into agreements with the local people such as winter rice fields filled with water to fallow the land, the setup of fishways and a survey of life conducted with the cooperation of universities and neighborhood elementary schools.

Suntory is pioneering action to build a society rich with biodiversity through its involvement in the Declaration of Biodiversity by Keidanren in January 2011 as well as participation in The Double 20 Campaign platform that helps the company engage and cooperate with people who are working to achieve the Aichi targets advocated by the Japan Committee for the International Union for Conservation of Nature (IUCN-J) in November 2017.

Biodiversity in a Natural Water Sanctuary from a Bird's Perspective

One of the main purposes of the Natural Water Sanctuaries is the revitalization of a wealth of biodiversity, and experts from the Japanese Society for Preservation of Birds carry out wild bird research every year (insect and animal research is also periodically conducted). We have formulated a Biodiversity Action Plan (BAP) and continually work to improve that plan at our Natural Water Sanctuaries throughout all of the primary bases of the Suntory Group.
The plant and animal life living in the forest will change if the typical functions of the forest can be revitalized. We believe that we can fully understand the ever-changing situation throughout the entire ecosystem supporting this life by focusing on birds of prey such as the eagles and hawks which stand atop the ecological pyramid.
Nest building and rearing of chicks by eagles and hawks at all the Natural Water Sanctuaries in Japan has been raised as a 2020 target with the purpose of advancing the development of a forest rich with biodiversity by taking the perspective of natural wild birds in the Natural Water Sanctuaries through research into these wild animals. Goshawks, buzzards, Japanese sparrowhawks, Eurasian sparrowhawks, owls, and other birds of prey have been confirmed in various Natural Water Sanctuaries.

Hosting the Natural Water Sanctuary Forum 2017 -- Forests that Protect Water and the Future of Life on Earth

This forum started in 2011 for the purpose of sharing knowledge about the broad range of research and maintenance in each Natural Water Sanctuary. The forum held in September 2017 was the seventh conference held since its inception. We regularly invite experts in various fields to provide guidance and cooperation to offer comprehensive reports that include trial and error in the research and maintenance of the Natural Water Sanctuaries and future activity policies. We deepened the debate through interactions that included a specific exchange of opinions at a poster session.

First Hand Experience with Forestry by Employees

Many Group employees and their families participated in the first-hand experience with forestry as a volunteer activity in the Natural Water Sanctuaries up until 2013.
In 2014, we started to have all Group employees take part in the first-hand experience with forestry training to cultivate understanding by allowing each and every one of our employees to experience the Suntory Coexisting with Nature values themselves. A total of roughly 7,100 people have participated up until now.

Ikurinzai - Timber Project: Utilizing Wood Nurturing Water and Forests

The Suntory Group calls wood material made from activities to nurture sustainable water and forests "Ikurinzai - Timber" (registered trademark) We are advancing activities that use not only artificial forests such as cedar and cypress but also broad-leaved trees such as oak and Mongolian oak as byproducts from our forest development based on the fundamental belief that mountains and forests have nothing wasteful and a hope not to waste anything.

Internal Use of Tables and Chairs Made from "Ikurinzai - Timber"

Tables fabricated using Ikurinzai - timber from cultivated forests was realized based on an idea of our employees to effectively utilize Ikurinzai - timber from cultivated forests while maintaining forests of Natural Water Sanctuaries. Today, we have installed various tables and counters that use Ikurinzai - timber from cultivated forests found in Gifu Higashi Shirakawa Natural Water Sanctuary in the employee cafeteria at the Odaiba Office and spaces of Suntory University*1.
We used Ikurinzai timber from Okudaisen Bunanomori Natural Water Sanctuary and the Kyoto Minami-Yamashiro Natural Water Sanctuary for the floors and furnishings in the Suntory World Research Center (Keihanna Science City), which was built in 2015 as a research and development site for both Japan and the rest of the world at the Suntory Group. In the Suntory Products Ltd. Kisogawa Plant, we adopted chairs that use Ikurinzai timber from the Gifu Higashi Shirakawa Natural Water Sanctuary.
Our employees are reaffirming the Natural Water Sanctuary Projects with more sensitivity in the natural environment they are able to experience each time they come in contact with the tables and chairs that use Ikurinzai timber from cultivated forests.

External Use of "Ikurinzai - Timber"

Ikurinzai timber extracted from Natural Water Sanctuaries are widely distributed through various markets with cedar and cypress materials at the core. Some of this timer is used in the construction of public institutes that neighbor the Natural Water Sanctuaries as well as for furniture. This wood offers the local people an opportunity to come into contact with the blessings of nature.
