Corporate Information

In 1955, Tokyo Bosai Setsubi Co., Ltd.(TBS) opened for business with a foundation philosophy of maintenance of fire protection systems installed on US military bases in Japan.

Since then, TBS has delivered fire protection systems and security systems to 19 nuclear power plants in Japan and 7 overseas.
