We are a leading steel bridge fabricator and erector in Japan, with more than 4,000 accumulated complete projects over the past 70 years. Our participation covers a range of steel bridge projects in Japan and abroad.

By employing our SC Deck, a highly durable steel and concrete composite decking system, site construction labour levels are reduced and construction durations decreased while achieving superior safety levels. This permanent steel formwork is lightweight and excellent for structural launching whilst completely replacing conventional formwork.

KMA and KMS expansion joint systems, made of metal and rubber composites, are bridge and road assembly parts designed to secure safe traffic of vehicles and pedestrians, to absorb the heat-induced expansion and contraction as well as vibrations generated by traffic or earthquakes, and have gained a reputation for high quality and reliability.

With greatest production capabilities in Japan, we participated in steel fabrication and erection for nearly all major multipurpose domed stadium projects and major ultra high-rise steel structure projects in Japan, nowadays being well recognized for the accomplishments unparalleled within the industry.

Characterized by low initial costs, design flexibility, lower interim costs, rapid construction, and accelerated occupancy, Kawada Building System (KBS) offers low-rise, non-residential pre-engineered metal buiding systems, coming with a complete package - initial investigations, planning, contracting, designing, construction, operation, and after-service.

Pre-stressed concrete bridges, designed to overcome concrete's natural weakness in tension with prestressing tendons (generally of high tensile steel cable or rods), are widely common among bridge types for longer span requirements than ordinary reinforced concrete bridges nowadays. Our strong presence in the industry is backed up with the achievements of our past numerous complex pre-stressed concrete brige projects including major cable-stayed bridge projects and extradosed bridge projects.

Prebeam Bridge, composite bridge structure combined with the merits of steel structure and concrete structure, is now gaining popularity in the industry due to numerous merits such as lower girder height, adaptive flexibility in road alignment, and lighter weight, as embraced for more than 900 bridges.

A larger number of bridges built several decades ago in Japan are about to enter a phase that they need major repair or rehabilitaion works to prolong their service life. With these repair and rehabilitation needs to increase further, our corporate resources are being distributed accordingly to develop bridge repair, maintenance, and upgrade technologies, and to embrace a variety of growing bridge repair and maintenance needs.

Being an architecture, engineering and construction firm with a long history in tradition that spans over 35 years, we have accomplished our building achievements, which encompass a great deal of aesthetically pleasing architectural landmarks, fine condominiums, and high-rise office buildings in metropolitan areas as well as unique structures represented by the world's tallest bronze Buddha statue. With the social consciousness change for global warming issues, our endeavours are unrelenting to develop environmentally friendly structures and products for value added buildings.

Our precast concrete products such as beams and pillars, with advantages over site casting of concrete, are manufactured in our strictly controlled plant, affording high quality assurance and speed-up construction on site. With the most comprehensive range of products, our sales efforts are directed toward numerous applications such as roads, railways, water and sewerage facilities, and commercial, industrial and government buildings .

Midori-chan is a revolutionary patented system designed to maximise vegetation growth and recycle waste, while dramatically minimising water usage by self-watering. This enveironmentally friendly planter system has been widely put into place in multifold projects, as demands of greener and cleaner communities has grown.

GEOneo is an air conditioning system that effectively utilizes steady underground-source heat with a heat pump throughout the year. The GEOneo system is characterized by less emission of CO2 and exhaust heat, less electricity consumption, and less operating cost than conventional air conditioning systems.

"Eco-Tank" is a large-scale rainwater underground storage tank system to protect people's lives from torrential flood damages whilst protecting urban environments. The "Eco-Tank" system is composed of pre-cast concrete assemblies, affording rapid construction with pin structures for member connection, high adaptivity to various sizes with a combination of 2 span types of beams, and overall lower cost coupled with fewer columns for storage volume requirements.

Our HRP-Series, developed together with the National Institute of Advanced Industrial Science and Technology (AIST), is a series of state-of-art life-sized humanoid biped robots, geared and developed to walk on two feet, stand up again on their own after falling flat, and perform several application tasks in cooperation with humans under various living and working environments. HRP-4, the currently upgraded platform, is being offered to universities or research institutes as a low-cost platform for research and development of human-cooperative humanoid robots.

NEXTAGE is a next-generation industrial robot system developed to work together with humans at production lines under manufacturing environments. The robot system has distinctive features such as low electricity consumption, compact body, position recognition, and easy installation, which enable high versatility, workability and safety.

Toho Air Service provides a wide variety of helicopter flight services, which range from scheduled commuter passenger flights, sightseeing tours, chartered flights, and medical and rescue flights, to construction-related lifting and transporting, and other customized projects.

New Central Air Service provides a range of airplane flight services, including scheduled commuter passenger flights, sightseeing tours, and flight trainings.
