[Press Release Distribution] Received a letter of appreciation from the President of NEXCO Central Japan Tokyo Branch - Safety and project management of the expansion joint replacement work and noise control were evaluated.
On October 28, 2026, we issued a press release regarding the receipt of a letter of appreciation from the Director of NEXCO Central Japan, Tokyo Branch. On October 9, 2026, our company received this letter of appreciation in recognition of our achievements in the "Replacement Work of Expansion Devices in the Yokohama Section of the Tomei Expressway." This letter of appreciation corresponds to the "Branch Manager's Award" in the Tokyo Branch's commendation category and marks our company's first honor since its establishment. As the main contractor, our company was responsible for the replacement work of expansion devices on multiple routes, including the Tomei Expressway, Ken-O Expressway, and Shin-Shonan Bypass. We completed the approximately one-and-a-half-year project without any accidents. The following efforts were primarily recognized: - Safety management and accident-free completion of construction at multiple sites across various routes - Strict adherence to the completion times for nighttime work through meticulous construction and regulation planning - Consideration for local residents through noise reduction measures and prior notifications The press release introduces specific initiatives that led to this recognition, as well as our product "Hybrid Joint" used in the construction. We encourage you to take a look.

Ten years since the Kumamoto earthquake - The "Hybrid Joint LL Type" expansion device adopted for the new Aso Ohashi Bridge, designed to accommodate fault displacement.
The main shock of the Kumamoto earthquake that occurred in the early hours of April 16, 2016, caused the Aso Ohashi Bridge to collapse, significantly impacting local transportation. Following recovery efforts, the New Aso Ohashi Bridge was opened in 2021. In the New Aso Ohashi Bridge, structures that can accommodate future fault displacements have been incorporated, such as the use of a steel simple box girder bridge over the fault. Additionally, the expansion joints installed at the bridge's seams are designed to follow fault displacements. Our bridge expansion joint, the "Hybrid Joint LL Type," has been adopted for this New Aso Ohashi Bridge, contributing to the safety and functionality of the bridge while accommodating large displacements. Japan is a country prone to earthquakes, and bridge design requires ensuring safety against Level 1 seismic motion (earthquakes occurring during the service period) and Level 2 seismic motion (maximum class earthquakes). Moving forward, our company will continue to provide technologies that support the safety and security of social infrastructure.

Crittec Industries receives the "Shinkin Central Bank Chairman's Award" at the Shinkin Excellent Company Awards - Selected for high evaluation of its 100-year durability bridge expansion devices and social contribution activities.
Crittec Industries, a manufacturer of expansion devices for bridges, received the "Chairman's Award of the Shinkin Central Bank" at the "2026 Shinkin Excellent Company Awards" held on March 16, 2026. This award is a system that selects outstanding companies from among the business partners of 23 Shinkin banks in Tokyo. Our company was nominated as a representative of approximately 20,000 business partners of Shiba Shinkin Bank and received the award after a rigorous screening process. The development of the bridge expansion device "Hybrid Joint Type 3LII," which achieves a durability of 100 years, was highly evaluated for its contribution to reducing maintenance costs through lower replacement frequency, as well as its role in mitigating social costs such as traffic regulations. Additionally, our social contribution activities, including the utilization of senior talent, promotion of health management, and the implementation of the experiential learning program "Crittec Academy" for elementary school students, were also comprehensively recognized. With this award as a catalyst, our company will strive for technological innovation and quality improvement aimed at realizing sustainable social infrastructure and creating further value.

The "100-Year Bridge Project" has started! Together with companies and individuals nationwide, we will promote the appeal of social infrastructure - A press release has been distributed.
Crittec Co., Ltd. has officially launched the co-creation project "100-Year Bridge Project," which aims to promote the appeal of the bridge, civil engineering, construction, and infrastructure industries, starting from July 27, 2026. A press release regarding this project has also been distributed. The "100-Year Bridge Project" is an initiative aimed at connecting people, companies, and ideas through the symbol of a bridge, and conveying the value and importance of social infrastructure to the future. In response to our call for ambassadors, various companies and individuals from different industries and positions, including the bridge, civil engineering, and construction sectors, as well as power infrastructure and tourism guides, have participated. Moving forward, we will leverage each perspective to collaboratively share the appeal and importance of social infrastructure. We will continue to work with our ambassadors to widely disseminate information about bridges and social infrastructure through social media and various media outlets. Additionally, this project is continuously seeking ambassadors from companies, organizations, schools, and individuals. Please pay attention to the activities of the "100-Year Bridge Project."
We will deliver various information such as construction examples, product introductions, exhibition announcements, and news from MESCO!
