The Prince Gallery Tokyo Kioicho is first in Seibu Prince's 62-hotel Japan portfolio to earn Green Key eco-certification
The Prince Gallery Tokyo Kioicho has become the first of Seibu Prince Hotels Worldwide's 62 domestic properties to earn Green Key, the international eco-certification — arriving as the group's recent headlines have run more to pickleball courts and naming-rights deals than to sustainability.

The Prince Gallery Tokyo Kioicho has earned Green Key certification, becoming the first of Seibu Prince Hotels Worldwide's 62 domestic hotels to hold the award, the company said in a 31 July release. Green Key is an international eco-label for hotels and restaurants run by the Foundation for Environmental Education, covering energy and water use, waste management, staff environmental training and community engagement, according to the release.
