Tanseisha's Vision

Your story. Our solution. One space.

Our Purpose : Drawing the future from space, adding new colors 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 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.

"Dansei" refers to the "rich color" of the two basic colors red (dan) and blue.
It is a word of Chinese origin that broadly refers to paintings, painters, and the act of painting. It is also the origin of our company name.

Our Values

Facing People 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.
Challenging beyond the present We keep on challenging while growing and transforming ourselves with flexible thinking and creativity.
Combining colorful personalities Sparkling creativity, advanced skill – We respect each other’s personality, and unite our hearts into one.
Enjoying our work We enjoy all our work and challenges.

Our idea of "creating space"

"Creating spaces" does not simply mean planning, designing, and constructing facilities (hardware), but is understood more broadly as "creating opportunities for experiences."
Going forward, we believe that our business scope will not be limited to the current solutions, but will also include a wide range of business development, including upstream, downstream and peripheral areas.

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.

Derivation of Tansei

“丹青”, a term originating from China, consists of 2 basic colors – Red and Blue – and denotes “an abundance of color.” This word also broadly refers to painting, painters and painted artwork.
Dedicated to artistic creation, Tanseisha invests its enthusiasm and creativity in creating rich, comfortable spaces in each and every project.

“丹青” is also a much-beloved word from ancient poetry. The famous Tang Dynasty poet Du Fu draws on the word “Tansei” to describe someone who is wholly absorbed in artistic creation. Tanseisha founder WATANABE Masaji loved the poem tremendously for its dedication to artistic creation.

“丹青”, also meaning diligence, is etched in the minds of everyone at Tanseisha who is wholeheartedly devoted to creating spaces. We also embrace the well-balanced symmetry of “Red and Blue” as colors of “passion and wisdom” in our company logo.
