Company information
OTOWA is the only manufacturer in Japan specializing in lightning protection, having explored "lightning" since its establishment. We want to create a safe and secure society that does not fear the natural threat of "lightning." We will realize this wish with our advanced lightning protection systems. ◆ A Wide Range of Products Available We offer a variety of products, including surge protectors for power distribution, as well as those for offices, factories, railway vehicles, and general households. We also accommodate custom orders, so please feel free to consult with us. ◆ Consulting for Lightning Protection Lightning protection varies depending on various conditions such as location. OTOWA will propose the most suitable lightning protection measures for those conditions. ◆ World-Class Lightning Testing Facilities Using top-class testing facilities and a diverse range of testing equipment, we conduct product evaluation tests and development in-house. Our achievements are highly regarded, and we also accept contract testing (Lightning Technology Center). ◆ Unique Quality of Zinc Oxide Devices We produce zinc oxide (ZnO) devices under strict management. These devices are the heart of surge protective devices (SPDs) and are indispensable for lightning protection.
