Keio Plaza Hotel Tokyo has been awarded the prestigious Grand Prize at the Eco Mark Award 2025, hosted by the Japan Environment Association. This marks a historic achievement for the hotel, as it becomes the second hotel ever to receive the highest honor, and the first in the hospitality industry to earn this distinction since the award was renamed the “Grand Prize” in 2017.

Keio Plaza Hotel Tokyo’s win highlights its commitment to sustainability and its role in setting an example for the hospitality sector.

Sustainability Efforts that Earned the Grand Prize

Keio Plaza Hotel Tokyo’s multi-faceted approach to sustainability includes several key initiatives that focus on reducing its environmental impact and promoting social responsibility. Some of the standout efforts that contributed to the hotel receiving the Eco Mark Grand Prize include:

• Company-wide SDGs Promotion: In June 2024, Keio Plaza Hotel created an SDGs Promotion Committee, which has driven numerous sustainability-focused initiatives across the hotel. These initiatives are designed to meet the hotel’s environmental and social governance goals, ensuring a broad commitment to the Sustainable Development Goals (SDGs).
• Food Waste Reduction: Keio Plaza Hotel Tokyo has introduced innovative strategies to combat food waste, transforming unused food into high-quality, delicious products. By embracing Japan’s “mottainai” philosophy, which emphasizes not wasting valuable resources, the hotel has found ways to repurpose food that would otherwise go to waste, further enhancing its sustainability efforts.
• Clothing Collection Boxes: In an employee-driven initiative, the hotel installed clothing collection boxes throughout its properties to promote resource recycling. This initiative encourages guests and employees to donate unused clothing, which is then recycled or upcycled into new products. The inclusion of this idea within the hotel’s operations has not only supported sustainability but also fostered a culture of responsible consumption.

These initiatives reflect Keio Plaza Hotel’s commitment to sustainable practices, resource efficiency, and environmental stewardship. By addressing critical issues such as food waste and clothing recycling, the hotel is playing a crucial role in the global movement toward sustainability in the hospitality industry.
