About us



Everyone as a Leader,
True to Themselves
Creating a Connected Society

Everyone is a leader of their own life. Leaders cherish themselves while also respecting others, and value connections as they create a future together. They embrace differences without fear or conflict, loving and respecting these differences. Through "speaking, listening, staying with differences and conflicts, and feeling with all senses," they engage in self-dialogue and dialogue with close relationships. Such leaders courageously shift from dialogue to a future of co-creation.

You, your family, organizations, communities, regions, countries, the Earth...
We believe that when your "small cup of happiness" overflows, a larger cup of happiness appears, leading to more people smiling.

Thoughts on Stepfamilies

Let's Become a Family Team!

We send our heartfelt blessings to those who are in the phase of creating a "stepfamily" in their lives.

As single parents who have supported both our children and our finances, we commend ourselves for our efforts and perseverance up to this point. Finding someone to remarry was not an easy task.

The depth of character and greatness of those who choose to partner with a single parent with children are immeasurable. While marriage brings joy and happiness, it undoubtedly also brings many anxieties and conflicts.

"Remarrying with children" may seem right for me,
but is it truly the best choice for my children?
The anxiety of suddenly becoming a parent is honestly indelible.
What does it mean to be a parent?

We also chose to be a stepfamily. Venturing into the unknown was daunting because there were no clear answers. Therefore, we made choices that were true to ourselves, carefully discussing what we really thought, one topic at a time.

Our journey was accompanied by "systemic coaching," a form of dialogue. Through discussions involving many anxieties and conflicts about various important themes like "last names," "terms of address," "ways of living," "family finances," "relations with parents," "wedding ceremonies," and "relationships with children," we were able to find our own answers.

With the lessons learned, we aspire to support all types of families.
