(Kawachinagano-shi, Osaka; President: Naoyuki Oida) have launched a voluntary organization, the Assistive Suit Association, to raise awareness of assistive suits and accelerate market formation.

■Manufacturers cooperate to expand the assist suit market
Assist suits (power-assist suits) are products developed to reduce the load placed on the body when lifting and lowering heavy objects by means of motor assist and the load-dispersing effect of artificial muscles and other devices. It can reduce the physical load in various industries such as logistics, construction, manufacturing, agriculture, medical care, and nursing care, where manual labor is required. With labor shortages and the aging of society becoming serious social issues in recent years, the market for assistive suits is expected to expand as a means of helping to shorten work hours, improve work efficiency, and support the employment of elderly people and women. On the other hand, customers are interested in utilizing assistive suits to secure employees and improve the environment in which they can continue working, but some say, “There are various types of assistive suits available, and we cannot find one that meets our needs,” or “There is no place where we can experience the suit even if we wanted to. From the sales perspective of a development company, we are faced with the issue of “it takes time and effort to negotiate with each company to have a place for demonstration. In order to break through this current situation, companies related to the Assistive Suit have decided to cooperate in raising awareness of Assistive Suit products, forming a market, and conducting educational activities. We have already held joint trial sessions for industry associations and companies on business trips, which have been well received. In the future, we will consider various initiatives in addition to holding events.
