Contributing to building a society that fosters biodiversity
We opened Namba Parks in 2003 and has been working to coexist with nature, including by installing a rooftop garden called Parks Garden. We have also been continuously working for many years to conserve biodiversity in areas along its railway lines.
In recent years, we endorsed the "Osaka Biodiversity Support Declaration" in May 2003 and the "Keidanren Biodiversity Declaration Initiative" in July of the same year. Furthermore, in June 2024, we will participate in the "TNFD Forum" and the "30 by 30 Alliance for Biodiversity" to strengthen our efforts to conserve biodiversity.
Through these activities, we aim to contribute to the conservation of the natural environment and the revitalization of local communities, and to pass on a rich natural environment to future generations.
Green Procurement Promotion (Green Procurement Guidelines)
当社は持続可能な社会の実現に向け、サステナブル調達を推進していく責務があると認識しており、NANKAIグループとして、サプライチェーン全体で取り組むべきであると考えています。
当初は備品等の身近なものの購入において、できるだけ環境負荷の小さいものを優先的に購入するグリーン購入の取り組みから開始し、2009年度より、毎年目標を設定して取り組んでいます。また、2019年度にお取引先に対するグリーン調達についての必須事項・努力事項を定めた「グリーン調達ガイドライン」を策定しました。
この取り組みの中で、お取引先様に当ガイドラインの周知と、環境に関するサプライチェーンでの取り組み内容を周知し、協力を働きかけております。

"Parks Garden" contributes to urban biodiversity
Namba Parks is a commercial complex with 10 floors above ground and 4 floors below ground, developed in 2003 on the site of the former Osaka Baseball Stadium. On the terraced rooftop (11,500 m2), the Parks Garden has been installed, with approximately 100,000 plants of approximately 500 species, including Trees such as dogwood and Wild cherry blossoms, and vibrant flowers such as Lavender and Rosemary, creating a forest-like landscape. A wide variety of birds and insects can be seen there, making it a rare place Osaka City that contributes to biodiversity.
In March 2020, part of the garden was renovated to include a wooden deck space, allowing visitors to experience the richness of biodiversity even in the heart of the city.
In 2020, we received the Flower Town Development Encouragement Award at the 30th National Flower Town Development Competition, sponsored by the Flower Town Development Competition Promotion Council.
In fiscal 2021, Parks Garden was featured in the Ministry of the Environment's "Collection of Case Studies of Collaboration between Developers and Local Communities: Achieving SDGs through Development Projects" as an example of "Creating New Vibrancy through Greenery."
In the Nikkei Plus 1 special feature published on June 4, 2022, the rooftop garden was ranked first in the "Enjoy a different world of greenery at a rooftop garden" ranking. It was selected as number one by seven out of 12 experts, receiving praise such as "a masterpiece of a rooftop park that Osaka can be proud of around the world."
A biological survey conducted with Obayashi Corporation from 2022 to 2023 confirmed that a diverse range of organisms live here, including the breeding of Sparrows, whose populations are feared to be declining nationwide.

Conclusion of the Green Partnership Agreement and the Osaka Biodiversity Partnership Agreement and their activities
In 2009, our company and Osaka Prefecture concluded a Green Partnership Agreement covering the entire railway line, aiming to promote the conservation of rich greenery and natural environments. Since then, we have been promoting environmental conservation activities such as creating biotopes in Kyosei-no-Mori (Sakai City) and Tanagawa area (Misaki Town,Sennan District).
Furthermore, in March 2014, we signed the Osaka Biodiversity Partnership Agreement with Osaka Prefecture, Misaki Town, and the Osaka Prefectural Research Institute of Environment, Agriculture, and Fisheries.
Coexistence Forest
Osaka Prefecture has designated 100 hectares of Sakai District 7-3 (approximately 280 hectares), an industrial waste final disposal site in Sakai City waterfront area, as a "Symbiosis Forest" and is currently developing the area. Since fiscal 2008, we have been utilizing our shareholder benefit program to make ongoing donations to Osaka Prefecture's "Green Fund," and employees have been volunteering to plant trees and contribute to forest development. To date, we have planted approximately 20,000 trees, expanding the forest to an area of 64,900 square meters. In recognition of these efforts, we were issued the first "Certificate of Support for Nature-Coexistence Sites (Trial Version)" by the Ministry of the Environment in March 2025, and received the full-scale support certificate in November 2025.

Tanagawa Biotope
Within "Ikiki Park Misaki," operated by Osaka Prefecture and other organizations, there is Tanagawa Biotope*, which aims to restore a rich natural space, and once a month employees from Osaka Prefecture, Misaki town, and our company carry out environmental conservation activities such as tending to the planted trees, managing the pond, and observing the wildlife. As shown in the photo, the area looked quite bleak in 2005, but subsequent maintenance activities have resulted in a lush green biotope in 2013.

In September 2025, the site was certified as a nature-friendly site under the Act on Promotion of Regional Biodiversity. Our company is a joint applicant along with Osaka Prefecture, Misaki Town, and the Research Institute of Environment, Agriculture, and Fisheries, a local independent administrative institution in Osaka Prefecture.
