Sustainability Initiatives

Keio Plaza Hotel is committed to contributing to the development of a sustainable society, as a "PLAZA" where guests can come together to relax and connect.

Since its opening, Keio Plaza Hotel has been a cherished “PLAZA” for a diverse range of guests, guided by our enduring “PLAZA Philosophy”. Rooted in this philosophy, we have led the way in pioneering inclusive and accessible services within the industry, while actively advancing environmental conservation initiatives.
Our initiatives include the reuse of wastewater and oil, rooftop greening, plastic reduction, and minimizing greenhouse gas emissions—efforts that have earned significant recognition for their impact. Looking ahead, we remain committed to ensuring the safety and security of our guests while focusing on reducing food waste, fostering diversity, and protecting the natural environment. Through these continued efforts, we aim to play an active role in building a sustainable society.
