Social innovation

We aim to redefine the current meaning of social value in response to various societal problems by directing our activities to create an environment, which is conducive to the happiness of as many individuals as possible. We have visualized our concept in a small venture, that we call “Leimond Village”. We have set our sights on creating a space in which the elderly, the young and disabled all support one another without barriers in living the way that each person desires to.

Our Foundational Principle

Create a joyful childcare experience
Feel a new wind blowing
Shape a future world where the smiles of children overflow
