Active Senior Membership Residence to Open: 'Active Senior Community Island Club Koyaruzawa Main Building' Launching First Phase (300 Rooms, 12 Floors) in Autumn 2026

Unimat Group's Unimat Active Senior Life Co., Ltd. (Headquarters: Minami-Aoyama, Minato-ku, Tokyo / President: Akira Ochiai) will open the membership-based residence for active seniors, 'Active Senior Community Island Club Koyaruzawa Main Building,' in Koyaru, Yachimata City, Chiba Prefecture, in autumn 2026.

For over 20 years, the Unimat Group has explored ideal models for urban development in Japan's aging society. Amid this journey, they discovered the land of Koyaru in Yachimata City, Chiba Prefecture—a region surrounded by lush forests and pristine water. Across approximately 1.5 million tsubo of satoyama (traditional rural landscape), the 'Yachimata Future City' urban development project has been launched under the theme of a 'New Era Hometown.' This initiative features a diverse range of facilities harmonizing nature and culture, including accommodations, restaurants, hot springs, golf, art, and outdoor activities. As the landmark of this vision, the membership-based residence for active seniors, 'Active Senior Community Island Club Koyaruzawa Main Building,' has been born.

Not a Nursing Home—The Second Life of the Golden Age 70s

Japan's baby boomer generation, who supported the nation's economic growth, are now entering their mid-70s, ushering in an era where approximately 10 million people will live as seniors. We believe the 70s are the most radiant stage of life and refer to healthy seniors as the 'Golden Age 70s.'

Mornings begin with walks along sun-dappled paths, breathing in the refreshing air. Days unfold with rounds at the 'Chiba Birdie Club,' featuring open fairways, or relaxing moments at the clubhouse, bringing a refined rhythm to daily life. At times, quiet reflection through art and music offers inner dialogue.

Engaging in hobbies and arts with younger generations, launching new businesses, experimenting with local fresh produce in satoyama cuisine, or even starting farming or running a shop. Sharing sweat and laughter with visiting grandchildren. This community brings to life a lifestyle that inspires imagination for a renewed self.

The Five Values Embodied by 'Yachimata Future City'

A 1.5 Million Tsubo Field—The Joy of Living in Nature

Inspired by Arizona's 'Sun City'—The Shape of Happiness

The foundation of Unimat Group's urban vision stems from 'Sun City,' a CCRC in Arizona, USA. Inspired by this mature community where seniors continue to challenge themselves and culture and smiles circulate, the group has spent over 20 years developing a Japanese adaptation. Thanks to Unimat Group's extensive experience in golf, resorts, and marinas, the integration of coexistence with nature and active lifestyles has become the core of this residence.

*CCRC…Continuing Care Retirement Community

Primarily developed in the U.S., CCRCs are senior living communities designed for active adults and dynamic seniors.
