We manufacture communications equipment and devices to be used for emergency telephones on expressways and railways.

We possess a cooperation method communications network under our original brand. We conduct development, design, assembly, installation, and maintenance in an integrated manner, so stable telephone communications can be secured at a low investment. Our products have long been adopted by Japan Railways, private railways in the metropolitan area, and expressway companies. Our products are used in the emergency dispatch telephone system of JR East and the Shinkansen bullet train. We think that our business development should be limited to the domestic market in order to maintain an integrated organization. Considering the scale of our business, we are not actively advancing overseas expansion. 


[Product description] Our products are installed for communications between passengers and administrators. They are utilized around ticket vending machines in stations, restrooms for handicapped persons, interchange tollgate ETC lanes, and so on. These are user-friendly systems in which it is possible to talk with a partner simply by pushing a button, just like a usual intercom. A distance between connections of up to 10 km per circuit becomes possible using our original technology. Our products have a long history of use, specifically by Japan Railways, private railways in the metropolitan area, and expressway companies.
