[April Dream] Tamiya Home continues to protect Japan's digital society from its 'skeletal' foundation.

We support the 'April Dream' project, which aims to make April 1st a day to share dreams. This press release represents the dream of the 'Tamiya Home Blacksmithing & Steel Construction Division (Saitama Branch)'. [April Dream] ~Building a society where everyone can live with peace of mind, using steel in places no one notices~ Tamiya Home continues to be a group that protects the skeleton of the digital society by supporting Japan's 'invisible infrastructure' with on-site craftsmanship through blacksmithing and steel construction. Tamiya Home Co., Ltd. (Headquarters: Tokorozawa, Saitama; President: Akihiko Tamiya) operates a Blacksmithing & Steel Construction Division at its Saitama Branch, engaging in high-difficulty construction projects including data centers and large-scale redevelopment. Our dream is to continue supporting Japan's digital society and regional safety with the invisible power of 'steel frames.' We aim to create a society where every on-site craftsman works with pride, confident that their work protects the future of our children. 'That one weld protects the lives of millions'—with this belief in our hearts, we will not stop moving forward in places no one sees. ■ Background of the dream: We pay with smartphones, children open tablets at school, and ambulances move quickly with accurate information—this ordinary daily life is possible because facilities called 'data centers' operate 24/7. According to the Ministry of Internal Affairs and Communications' 2025 Information and Communications White Paper, data centers are positioned as the 'fourth lifeline' alongside electricity, gas, and water. The domestic market is expected to double from approximately 2.7 trillion yen in 2023 to 5.1 trillion yen in 2028. Global tech giants like AWS, Microsoft, Google, and Oracle have declared investments in Japan, and a construction rush continues. 'Why build in earthquake-prone Japan?' The answer is paradoxical. Because it is earthquake-prone, Japanese construction technology has been honed to the world's highest level. Japan is trusted as a construction site for 'social infrastructure that must never stop' precisely because of its advanced seismic and vibration-control technology. And it is Tamiya Home's job to realize the safety drawn in blueprints as 'real steel frames.' ■ Current initiatives: [Initiative 1] Challenge in data center construction: 'The future where AI becomes social infrastructure will surely come. We should be a company that can build the necessary buildings.' Under President Tamiya's decision, we entered the field in 2023. We have steadily accumulated achievements and trust in a special environment requiring high security and high-precision management. [Initiative 2] Participation in landmark architecture and large-scale redevelopment: With technical capabilities cultivated in top-tier projects like Azabudai Hills, we are continuously appointed as a 'primary subcontractor' for super general contractors. In 2025, we achieved annual sales of approximately 1 billion yen in the blacksmithing and steel construction business. [Initiative 3] Cycle of 'destroying' and 'creating': Tamiya Home removes regional dangers by safely 'demolishing' old buildings. At the same time, we 'create' disaster-resistant infrastructure with the latest blacksmithing and steel construction technology. This dual approach of 'demolition for protection' and 'creation for protection' is the foundation of our business. ■ Future dream: The peace of mind of being able to contact family via smartphone during a disaster. The reliability of ambulances moving quickly based on accurate information. That the infrastructure protecting regional safety is passed on to the next generation. That we continue to build those invisible frameworks with our own hands. That is the dream of the Tamiya Home Blacksmithing & Steel Construction Division. ■ Thoughts from Daisuke Hata, Saitama Branch Manager and Construction Department Manager: 'Our job is to turn the strength drawn in blueprints into reality. In sites like data centers that require high load and high precision, a craftsman's dedication to every weld and bolt becomes the boundary line for whether the system stops or endures during a disaster.' Hata, who has been in the construction industry as a craftsman since age 17 and holds a First-Class Building Construction Management Engineer qualification, continues: 'Feeling that the building I am working on is protecting Japan's communications and people's connections is my greatest pride.' The core of data center disaster prevention is the 'seismic isolation structure.' This mechanism, which escapes earthquake energy by installing isolation devices between the building and the ground, assumes that the steel frame skeleton is assembled with the strength and precision of the design. If there is distortion in the steel frame or insufficient welding strength, earthquake energy cannot be correctly escaped to the isolation device. In addition, with the spread of generative AI, floor loads in the latest AI data centers are set at nearly double the conventional level. To support this super-weight even during intense earthquake shaking, precise steel frame assembly and welding technology are essential.
