Taiyo Group Celebrating 100 Years

Taiyo Kogyo Corporation, along with our group companies TSP Taiyo and ACTIO CORPORATION is celebrating 100 years in business. Taiyo Group consists of membrane architecture specialist Taiyo Kogyo Corporation, event planning and consultant TSP Taiyo, and event and facility operator ACTIO CORPORATION. The group will jointly carry out a series of commemorative events throughout the year.

Taiyo Group was established in 1922 as Nomura Tent Shokai. The company was re-established during the aftermath of WW2 with only a pair of scissors and a sewing machine. Dedicated to “serving society and delivering memorable moments”, the company has given life to unique products taking advantage of the benefits of membrane materials. Through their involvement in the 1970 Osaka Expo, Taiyo Kogyo participated in the fabrication and operation of many large-scale pavilion structures. This led to the establishment of TSP Taiyo and ACTIO both specializing in their fields. Eventually, Taiyo Group has grown to the 74 billion Yen group today.

For the anniversary of the 100th year in business, the group will carry out joint programs aiming to strengthen the bond and generate a synergistic effect between the group companies, furthering the possibilities of membrane architecture and the experiences created within the created space.

■Anniversary logo for the Group

To celebrate the 100th year, Taiyo Group has created a logo to be used among the three group companies. The logo which is inspired by the shining sun represents the group’s businesses that have expanded through the century. This is the first time for the three group companies to have a shared logo. The logo will be used on websites and business cards throughout the year.

■Yuki Nohmura is appointed president of Taiyo Kogyo Corporation

In March 2022, Yuki Nohmura, a descendant of the founder of the company, was appointed as President of Taiyo Kogyo Corporation. Nohmura became the president of TSP Taiyo in 2017, contributing to the growth of the company by increasing its sales by 50%. Taiyo Kogyo on the other hand has been struggling amidst the stagnant construction market. His return to Taiyo Kogyo Corporation aims to strengthen the foundation of the business under his leadership. In addition, Yoshinori Ikezawa was appointed president of TSP Taiyo in June 2022. Ikezawa has been a leading force in the core business of TSP Taiyo for over 30 years, participating in the planning and operation of events such as the World Resort Exposition (1944) and the Aichi World Expo (2005). For the past 5 years, he has supported the growth of TSP Taiyo as Vice President.

■Looking toward the next 100 years

Taiyo Group’s involvement in construction, events, and facility operations is based on our unique focus on membrane technology. Further development of the possibilities of membranes, is crucial to our growth in the next century.

Membrane materials are compact and foldable, making them an optimal material for the space environment. Taiyo Kogyo Corporation has worked on projects with JAXA (Japan Aerospace Exploration Agency), Tokyo University of Science, and Shimizu Corporation to develop the “Space Colony Demonstration Module”. In June, Taiyo Group invested in the company SPACE ONE, a launch service for small rockets, aiming to become further involved in the space-related business, including event planning and facility operation around the launch pad. Taiyo Kogyo Corporation is also involved in the development of wind-power generated ships with a membrane sail, in hopes to provide a solution to the energy problem.

In addition to research and development, it is important for us to maintain our top share as large-scale membrane architecture (tent architecture) specialists. Through the harsh economy and social environment, Taiyo Group will continue to contribute to society through the creation of space utilizing membrane technology, to lead the next 100 years as leaders of the market.
