Our Mission

At MBK Senior Living, we believe that a fulfilling and meaningful life knows no age limit. That's why we are dedicated to creating an environment where seniors can embrace yoi shigoto and discover their ikigai.

Yoi Shigoto, which translates to "good work" in English, represents the idea that work can bring satisfaction, purpose, and a sense of accomplishment. Ikigai, on the other hand, refers to "a reason for being" and encompasses the idea of finding meaning in life through a sense of purpose. We recognize that each individual has a unique ikigai, a personal motivation that drives them forward. Here at MBK Senior Living, we are committed to helping our residents discover and cultivate their own ikigai through engaging social activities and wellness programs.

Practiced together, these philosophies ensure we deliver on our commitment to encourage wellness, build trust, and contribute to society. Our mission at MBK is to embrace innovation and empower our residents to continue to grow, learn, and live each day with purpose.
