Continuously invigorate business and society through small accumulations of individuals’ happiness.


One small happiness at a time, society can change.

We see a society that values individuals and their happiness as a driving force for invigoration and growth in a constantly changing world. A society in which we make the most of the time we have, valuing both private and professional lives. A society in which we learn, create, meet, discover, play, and enjoy at work and home alike.
This is a society prepared for anything, full of happy people and successful business.

In this society, TPO is a partner and culture shifter for companies who represent the future of business and lifestyle, now. Together, we set a new standard for happiness and success in life and at work. We foster mindsets and practices for human-centered growth, inclusion, creativity, and passion, so that organizations and individuals can grow and evolve.

And all of this can happen, one small happiness at a time.


  • Happiness
    Everything we are about is creating a path to happiness. It is not success that brings happiness, but the happiness that brings success. We strive to bring happiness with every interaction.
  • Human
    If it’s not human-centered, it’s not part of our business. We recognize the importance of connecting as humans to drive better outcomes in any situation. Our services are hands-on, personalized, and designed with people in mind.
  • Inclusion
    Invigorating business and society requires everyone to be included, and to be valued. Using all of our strengths is what will keep us successful and growing. This starts within our own diverse team, setting an example for our clients.
  • Creativity
    Creativity is essential to finding our way in a rapidly changing world. Curiosity, experimentation, and radical collaboration all come together to discover what is needed next. What we offer will change, and that’s a good thing.
  • Passion
    This is what gets us out of bed in the morning. Passion means there is no finish line, only continuous growth toward accomplishing what is important. We are passionate about our mission, and that reflects in every service that we provide.


Having grown up and worked abroad, I was surprised to find out how difficult it was to pursue both private and professional lives in Japan. Why should one have to choose between family and work?

When I was working and raising my two children at the same time, even with help from family members and day-care at the workplace, I still had so much on my to-do list. I was always stressed and feeling guilty from not being able to handle all the tasks that needed to be done. Whether it be caregiving, illness, hobbies, etc. I believe many are in similar situations of needing support.

TPO is my answer to this issue. I decided to commit myself to bringing harmony in employee’s lives so that they do not have to choose between one or the other. Through our service, we want to invigorate employees and work toward a society that values individuals’ lives, and their happiness.
