Disasters have become more and more diversified with the aging of society as well as the larger and more complex building structures in urban areas. As a result, there have been increasing demands for technologically advanced equipment necessary for ire fighting in order to cope with these disasters. The National Research Institute of Fire and disaster has developed fire fighting equipment which makes the most use of new materials and the latest mechatronics technology to meet these needs.
The operation and bringing of the edge of the ladder of an aerial ladder truck closer to a suitably targeted position is no easy task, even for veteran firefighters The use of an automatic ladder setting-up system enables a ladder to be operated quickly and accurately simply by adjusting the system's telescope on the target.

A 3-Section ladder for fire fighting is an indispensable piece of equipment for fire fightings and rescue activities However, existing ladders are made of steel and are, therefore, heavy and to be a severe physical burden for fire fighters.
High tensile aluminum alloy is used as the material for the 3-section ladder for fire fighting, and the structure of the ladder has been optimized through the use of a computer. As a result, the Institute has been successful in reducing the weight of such ladders by one half there present weights.

The Institute has developed a computer control system whose goal is to let even beginners operate pumps to the same extent as full-time fire fighters. Joint research is currently being promoted with various enterprises for the purpose of putting the system into practical use Completion of fire fighting vehicles loaded with the system will enable anyone to perform high level operations with one or more pumps easily

Freezing fire hydrant main valves which are around 1.2 meters below the ground has been a serious problem in cold regions The Institute has thus examined ways of overcoming this problem. As a result of computer calculations of two-dimensional un-steady-state conduction, for instance, in the case of the city of Asahikawa in Hokkaido, the laying of insulation material ten centimeters thick and three meters in diameter horizontally fifty centimeters below the ground was found to be an extremely effective countermeasure for this problem. This method has been introduced in Asahikawa City and elsewhere with very good results.
