Biodiversity Preservation



In recognition of the importance of the preservation of biodiversity, the Nissui Group revised its Environmental Code in 2014 and upholds preservation of biodiversity in its Policies.
The preservation of the sea is crucial for the Nissui Group, whose business relies on its bounties. In order to sustainably utilize marine resources, efforts to maintain the health of the sea itself and to aid its recovery, as well as resource management, are essential. To this end, we are engaged in preservation activities that take a holistic approach to the “forest, river and sea.”
It all started with a lecture titled “What oysters taught me” given at Nissui’s head office in February 2011. The lecturer, Mr. Shigeatsu Hatakeyama who was operating an oyster farm in Kesennuma, Miyagi Prefecture, taught us about “Uotsukirin (fish-breeding forest),” a traditional idea of Japanese fishers, and how abundant forests are the very source of abundant seas.
Since then, Nissui has been engaged in activities based on the concept of a coordinated preservation of the “forest, river and sea” at various locations.

The Forest that Protects Spring Water Nurturing Fish and the Sea

Tottori Prefecture is the home of the Nissui Group companies Yumigahama Suisan Co., Ltd., which is engaged in the aquaculture and processing businesses and Kyowasuisan Kabushiki Kaisha, a fishery company. The farming-related facility of Yumigahama Suisan is located at the foot of Mt. Senjozan which is in Daisen-Oki National Park of Kotoura Town, Tottori Prefecture and trees in certain parts of the surrounding broad-leaved forest have died and required maintenance.
On October 30, 2018, Tottori Prefecture, Kotoura Town and Nissui entered into a forest preservation and management agreement in order to preserve the surrounding 5.933 hectares of forest as the “The forest that protects spring water nurturing fish and the sea.”
On April 7, 2020, the Nissui Group was certified as a collaborative business by the Japan Committee of the United Nations Decade on Biodiversity (UNDB-J) for this forest preservation activities.

Preservation Activities

Continual preservation work is essential to protecting forests.
At the Nissui Group, ever since we entered into the Agreement, we have been conducting employee participation-based preservation activities on a yearly basis. For the participants, these activities become a valuable formative experience in which they get a real sense of the interrelatedness of the “forest, river, and sea,” and their relationships to them. Moreover, through interactions with the people of Tottori Prefecture involved, it is an opportunity for participants to gain familiarity with the local culture and are able to cultivate relations among members of Group companies.

Since FY2021, we have been collaborating with Tottori University to conduct a forest survey with the aim of making our conservation activities more scientific. The results of the study showed that about 80% of the seedlings planted in our activities in FY2018-2019 were active and growing well as of 2021. We will undertake another survey of the vegetation inside and around the “Forest that Protects Spring Water Nurturing the Fish and the Sea,” and plan to make further use of local species of trees in our tree-planting activities in FY2020 and beyond. We hope to further improve our activities so that we can establish a forest that is closer to one that would naturally occur and that we can preserve the forest in a practical manner.

Due to the impact of the COVID-19 spread in FY2021, the Nissui-sponsored preservation event was cancelled; however, the "Green Scouts (Note) Exchange Meeting" organized by the Tottori Prefecture Planting Trees Promotion Committee was held on September 11, and representatives from Nissui/Kyowa Fishery participated in a meeting held online. During the lecture portion of the meeting, in addition to introducing the Nissui Group's business, we explained the connection between forests, rivers, and the sea, and conveyed the motivation behind a fisheries company's involvement in forest conservation. Sixteen 5th and 6th graders from Tottori Prefecture participated in the exchange meeting, and after taking part in woodworking and other activities, they then worked up a sweat for about an hour clearing underbrush in the Nissui Forest.

(Note) Green Scouts: The Green Scouts are an organization sponsored by the Tottori Prefecture Planting Trees Promotion Committee. Its purpose is to get the children who will eventually lead the next generation of society to familiarize themselves with greenery, develop an affection for it, and protect and nurture it, and in doing so cultivate an attachment to their home communities and grow into people with well-rounded minds and the capacity to love their fellow human beings.

Preservation Activities of Utsunuki Green Zone

“The Utsunuki Green Zone” is a “satoyama (village forests)” adjacent to the Nissui Tokyo Innovation Center, which was built in 2011. 
Every year since 2013, activities have been conducted, under the instruction of the “Utsunuki-Midori-no-Kai,” to preserve the natural environment in areas surrounding the business location and to promote co-existence with the regional community. The activities begin with a classroom lecture at the log house within the zone, in which participants learn about the connection between the “forest, river and sea,” as well as the flora and fauna of the "satoyama," which is followed by various tasks such as mowing the underbrush in the "satoyama.”

On November 14, 2020, activities were conducted for the eighth time. Having downsized the activities as a measure against COVID-19 infections, twelve Nissui employees participated. On the day, participants repaired the stairs and cleared the underbrush in the Green Zone. The program could not be implemented in FY2021 due to the spread of COVID-19 infection, but we are planning to resume the program in FY2022 and beyond.
