「Total research and development expenses for the cumulative third quarter of the fiscal year were ¥240 million. There were no material changes in the status of the Group's research and development activities during the cumulative third quarter of the fiscal year.」

「The company developed a pile construction method that reduces environmental impact and also contributes to society by using ASTICON, a recycled material derived from its own factories, together with a solidifying agent for excavated soil generated at construction sites.」

「In the foundation business, the company is developing environmentally friendly piles, including its proprietary Ecotan-Cal and other products, known as G (Green)-ONA piles. It is also optimizing product designs and materials to reduce manufacturing costs through greater production-process efficiency, improving factory production lines and manufacturing capacity, and implementing measures to reduce failure costs at factories and construction sites.」

「Total research and development expenses for the cumulative third quarter of the fiscal year were ¥422 million.」

「Total research and development expenses for the cumulative first quarter of the fiscal year were ¥135 million.」

「For precast products for civil engineering structures, including shield segments, PC wall systems, soldier pile panels, and ultra-high-strength fiber-reinforced concrete (UFC), the company is focusing on improvements incorporating high-value-added functions that address customer needs, differentiating itself from competitors, and developing products and construction methods that improve profitability.」

「Total research and development expenses for the cumulative third quarter of the fiscal year were ¥225 million.」

「Total research and development expenses for the cumulative second quarter of the fiscal year were ¥149 million.」

「Total research and development expenses for the three months ended the first quarter amounted to ¥76 million.」

「Total research and development expenses for the cumulative third quarter of the fiscal year were ¥269 million.」

「Total research and development expenses for the cumulative second quarter of the fiscal year were ¥201 million.」

「Total R&D expenses for the current first quarter of the consolidated fiscal year were ¥92 million.」

「For the construction of PC wall systems, the company adopted a construction method suitable for confined sites and slopes, and focused on improving the construction method to further enhance constructability.」

「Total research and development expenses for the cumulative third quarter of the fiscal year were ¥267 million.」

「Total research and development expenses for the cumulative second quarter of the fiscal year were ¥170 million.」

「Total R&D expenses for the cumulative first quarter of the current consolidated fiscal year were ¥83 million.」

「Going forward, the company will seek to turn demand and expectations for precast concrete products into business opportunities, taking into account i-Construction, advocated by the Ministry of Land, Infrastructure, Transport and Tourism, in response to chronic construction labor shortages and driven by transport infrastructure and large-scale capital investment for the Olympic and Paralympic Games, construction of the Linear Chuo Shinkansen, reconstruction projects following the Great East Japan Earthquake, energy procurement other than nuclear power, and initiatives to reduce environmental impact, among others.」

「Since inventing the NC-type steel-wire concrete pole in 1951, the company has continued its tireless research and development of concrete piles, including foundation piles, PC wall systems for earth retention, and precast products. It has also focused on developing environmentally friendly, low-noise, low-vibration, and low-spoil construction methods for concrete piles and other products, in addition to ensuring economic efficiency and technical reliability.」
