Tanseisha has formulated "Purpose/Our reason for existence" and "Value/Our values" as the new group philosophy for the Tanseisha Group.
In addition, in preparation for 2046, which will mark the 100th anniversary of the founding of the exhibition decoration business by Masaharu Watanabe in 1946, we have established "Our Future Vision 2046," clarifying how we want to remain a company that is needed by society in the long term.

In 2022, we launched a project team composed mainly of young employees, and conducted discussions while listening to a wide range of opinions from employees of various ages and occupations, as well as external stakeholders. After deliberation at the Board Director meeting, we formulated the group philosophy and "Our Future Vision 2046."
"Purpose / Our Reason for Existence" incorporates the character "Tansei," from which the company name Tanseisha is derived (a word that refers to "rich color" from the two basic colors red and blue, and which by extension refers broadly to paintings, painters, and the act of painting), and is defined as "Paint the future from the perspective of space, and bring color to people and society."
The Tanseisha Group will continue to take advantage of its diverse individuality and challenge itself to create spaces that move people's hearts.
Our Purpose : Drawing the future from space, adding new colors to people and society.
Envisioning the future through space and bringing color to people and society.
We, Tanseisha Group, are professionals in creating space for imaginations to grow.
Our philosophy of space creation –
It is to give form to something that does not yet exist in the world.
And to create experiences to grow imaginations, delivered by the space.
Joy, surprise, comfort, and inspiration.
To color the lives of people gathering in the space, with the rich emotion.
And to brighten society with the rich colors of “Red and Blue (=Tansei).”
We have been, and will be continuing to challenge ourselves to create space for imaginations to grow,
by harnessing our colorful personalities.
Our Values

We are sincere in our commitment to the wishes of our associates and stakeholders who are connected through the space.
Putting our hearts and souls into our work
We engage in each project with sincerity, with professional pride and skill.

Tanseisha: Vision 2046
We continuously strive to be not only a group of professionals creating space for imaginations to grow,
but a group of challengers to open up the possibilities of space and ourselves.
What can we do by creating spaces for a changing society?
Sustainability
We will face environmental and social issues, including climate change, and work sincerely to find solutions. By transforming the space creation process into a sustainable one and creating valuable spaces, we will contribute to the realization of a more colorful and sustainable society.
Borderless
We will seamlessly expand our business by crossing all boundaries - overseas and domestic, urban and local, real and virtual - and create unprecedented experiential value by co-creating with clients and partners around the world. Furthermore, through the creation of spaces, we will enhance the appeal of valuable culture, nature, and technology from all over Japan and spread it to the world.
Providing moving solutions for changing markets and customers.
Strengthening the foundation
By proactively adopting cutting-edge technology and new values, and constantly honing our fundamental problem-solving skills, we aim to reach even greater heights as professionals in "creating spaces that move people's hearts."
Expanding the area
We aim to be the best partner in providing spatial solutions that "move the heart" by facing the complex and wide-ranging challenges faced by the market and our clients, and by expanding our business into new fields and new business models without being bound by traditional frameworks.
To that end, we continue to evolve.
People-centered organization and working style
By having diverse talents work together and create together, we will grow into a more flexible and innovative group. By ensuring diversity in work styles and respecting each individual's lifestyle and happiness, we will increase our creativity as a group made up of strong individuals.
Creating spaces that care about people
In a society where people will need spiritual richness and a return to humanity, we will continue to pursue our own possibilities in order to create even greater excitement in spaces that connect people.
Comment President and Chief Executive Ofcer Osamu Kobayashi

The business environment surrounding our company is changing faster and more dramatically than ever before. In this environment, we have clarified our raison d'être and our vision for the future in order to demonstrate and execute a consistent management policy that will not waver even in the face of short-term changes in the situation.
In formulating the plan, we paid particular attention to ensuring that employees could understand and empathize with it. We gathered a wide range of opinions from both inside and outside the company, including through various employee-participation events, and repeatedly discussed and verbalized "what is Tanseisha-like?" and "what kind of company do we want Tanseisha to be in 2046?" I feel that by carefully pursuing this process, we were able to put together something that incorporates the thoughts, expectations, and will that are important not only to management, but to employees as well.
With this new group philosophy and vision for the future in mind, we at the Tanseisha Group will continue to take on new challenges so that we can create a future filled with color.
