The 'Tsurui-Seibu Forest' in Tsurui Village, Akan District, Hokkaido, owned and managed by Seibu Real Estate Co., Ltd. (Head Office: Toshima-ku, Tokyo; President: Asahide Saito), was certified as a 'Nature Co-Benefit Site' by the Ministry of the Environment on June 30, 2026, under the Regional Biodiversity Enhancement Act. This recognition is due to the presence of numerous rare species and the ideal collaborative efforts between the public and private sectors for biodiversity conservation. This marks the first 'Nature Co-Benefit Site' certification within Kushiro Shitsugen National Park, and the third for our company, following 'Hanno-Seibu Forest' and 'Tokyo Garden Terrace Kioicho'. 'Tsurui-Seibu Forest' is a vast forest of approximately 3.91 million square meters, entirely located within Kushiro Shitsugen National Park. It consists of birch and mizunara groves, and natural alder forests connected to Kushiro Shitsugen, also serving as the entrance to Miyajima Cape (Ministry of the Environment-owned land), a scenic spot within the park. Our company is undertaking the following initiatives to maintain an environment where local flora and fauna can thrive, with a particular focus on conserving rare species such as the black woodpecker, which nests in large trees, and the Japanese crayfish, unique to the spring water areas that nourish Kushiro Shitsugen: - Installing trail cameras (cameras that automatically record by detecting heat) to monitor the habitat of Ezo deer, and piloting measures to protect vegetation. - Confirming water conditions and sediment runoff in areas where rare species grow. - Cooperating with Tsurui Village and the Kushiro Nature Conservation Office of the Ministry of the Environment to implement adventure travel* and manage trails appropriately. These efforts led to the certification as a 'Nature Co-Benefit Site' under the Regional Biodiversity Enhancement Act. *Adventure Travel: A travel style that allows travelers to experience the local natur
