In October 2026, Tanseisha will celebrate its 80th anniversary.
Tanseisha's spatial design began in October 1946, when our founder, Masaharu Watanabe, worked on the interior decoration of a department store in Ueno, Tokyo, which was booming after the war. The company made great strides after achieving success in creating a pavilion for the 1970 World Expo (Osaka), and has continued to hone its technology and creativity, expanding the field of Comprehensive display business in the 80 years since its founding. Going forward, we will continue to take on the challenge of creating spaces that move people's hearts, making the most of the diverse personalities of each and every employee of the Tanseisha Group.

About the 80th anniversary logo
The logo represents our 80 years of history, and the diverse "layering of individuality" of each of us, inspired by one of the Tanseisha Group's values of "Combining colorful personalities." The slogan "Layering Colors" also expresses our determination to continue challenging ourselves to create spaces that move people's hearts, with the same unchanging attitude, and to paint a future filled with color together with all our stakeholders.
