Lightning is a natural phenomenon, but its damage can have a significant impact on buildings and human lives.
We believe that through lightning protection equipment, we can support the safety and security of your lives.
However, simply preserving tradition is not enough to meet the changing times and societal needs.
We value the spirit of ""unchanging principles and evolving trends.""
While preserving traditions that should be passed down, we boldly take on challenges to change what needs to be changed to suit the times.
This is the fundamental stance of our manufacturing.
We at Osaka Lightning Rod Industry Co., Ltd. aspire to continue contributing to society, growing, and being a company that our employees can be proud of.
With our mission to protect people and cities from lightning strikes at heart, we will continue to move forward into the future without ceasing to take on new challenges.

Otowa has significant engineering and test capability to enable custom product development to meet users requirements.

Since its founding, Kandenko has been actively carrying out its operations with the aim of ensuring the mutual prosperity of the shareholders, customers, and the local community. Through these efforts, Kandenko has grown the one of Japan’s leading general infrastructure firms, and earned high acclaim and a solid reputation for its contributions to the creation of comfortable living environments, pleasant yet cutting-edge workplaces, and safe and functional local communities. Furthermore, Kandenko plays a key role in the growth and development of companies, local authorities, and local communities by providing the products and systems that are backed by state-of-the-art technologies and know-how, now in such high demand by today’s society.

Since our founding in 1930, we have been advancing lightning protection technology for over 95 years.
Our products have been adopted in critical facilities, including railway infrastructure, worldwide, from Southeast Asia (Thailand, Vietnam, etc.) to the United States, South America, and EU countries.
Beyond simply selling products, we offer end-to-end solutions for reducing lightning risks, including proposals for lightning protection systems (LPS) to protect buildings and human lives, lightning protection measures (SPM) for electrical and electronic systems, and even lightning observation systems and lightning strike information (Franklin Japan). We provide comprehensive one-stop consulting services, from on-site surveys and countermeasure proposals to product provision and maintenance.

SHODEN Corporation is a Japan-based engineering company specializing in the protection of information and communications infrastructure. Since its founding in 1965, SHODEN has provided technologies and services that protect critical facilities from lightning, earthquakes, and other risks that threaten stable operations. The company’s core business areas include lightning and earthquake protection, network and security systems, and facility engineering. SHODEN designs, manufactures, and supplies a wide range of products such as surge protective devices (SPDs) for power and communications, seismic isolation systems, optical fiber network equipment, and electrical and communication boards.
In addition to manufacturing, SHODEN offers integrated services covering system design, construction, installation, maintenance, and consulting. By delivering one-stop solutions, the company supports data centers, telecommunications facilities, public infrastructure, financial institutions, and transportation systems that require high reliability and resilience. Through continuous technological development and a strong commitment to quality, SHODEN contributes to a safe and reliable information-oriented society.

The company offers solutions and services for lightning and surge protection as well as safety equipment – fields in which, with more than 900 patents and utility models, DEHN is a leading innovator. The company’s products protect people and buildings, systems and telecommunications technology, process industry, as well as photovoltaic systems and wind turbines.

Tridelta Meidensha GmbH develops and manufactures metal-oxide surge arresters for high and medium voltage applications. Based in Germany, we combine deep expertise in ZnO varistor technology, materials science, and high-voltage engineering to ensure reliable arrester performance under demanding service conditions.
Our portfolio includes surge arresters for AIS and for GIS applications using dry air insulation, as well as for distribution systems, railway applications, and renewable energy installations. We provide solutions for applications requiring multi-column, high-energy surge arresters for HVAC and HVDC systems, addressing system-specific requirements.
We offer both porcelain- and polymer-housed designs. Porcelain housings provide proven mechanical strength and long-term reliability, while silicone housings offer excellent performance in polluted environments and reduced maintenance.
We support utilities and OEMs with application engineering, insulation coordination, and customized arrester solutions.

Meidensha will showcase solutions that enhance the reliability and long-term performance of wind power facilities.
Our Blade Receptor, designed for environments with frequent lightning and salt corrosion, delivers excellent durability and stable operation. We will also present polymer-housed surge arresters for reliable overvoltage protection, an IoT-based monitoring system for efficient and proactive maintenance, and O&M services backed by over 20 years of experience. Founded in 1897, Meidensha operates 51 MW of wind power in Japan and advances renewable energy toward carbon neutrality.

Through continuous research and innovation in lightning protection, high‑voltage engineering, and renewable energy technologies, we collaborate with researchers and engineers worldwide to improve the safety, reliability, and resilience of future energy infrastructure.

As a subsidiary of a global leader in surge protection with trailblazing innovations in spark gap technology, we proudly serve as a trusted partner delivering comprehensive system protection solutions.

Our current growth stems from the accumulation of diverse knowledge and technical expertise gained through our involvement in the field of lightning surge measurement, which began with our encounter with KAMINARI SAMA.
