“Utilizing this artificial mineral enables the creation of vibrations
that positively impact blood flow
and other water substances in thebody. By promoting blood circulation, this helps protect the bodyfrom becoming cold and fatigued.”With such innovative products,Mr. Imaizumi sees NAIGAI as
much more than a sock manufacturer, but a “Leg Solutions Company”. His aim now is to bringthese solutions to millions morecustomers worldwide.

look. ‘SUASiC’ was designed to address the concerns of women who
wear pumps and sandals in thesummer, explains the president.
“When they wear pumps or sandals barefoot, their feet would become sticky, slip, or could possibly
even get hurt. It could also damage their shoes. ‘SUASiC’ doesn’t
slide around in the shoe, providing a solution to issues such as
friction and blisters. The gripping
capability of the fabric on the footprevents any sliding and eliminates
the discomfort that many people
complain of. We are currently developing it for men also.”
The development of products
such as SUASiC serves as testament to NAIGAI’s commitment tosolving customer issues. And that
includes more complex issues encountered by particular customer
groups with special needs, such as
the elderly, people with disabilities
and pregnant women.
With Japan’s population aging rapidly, NAIGAI has placed
particular focus on the elderly,
who often encounter problems
such as foot pain, joint pain, hippain, or swelling feet. In response,

As people with disabilities have
similar concerns as the elderly, thecompany has also focused on products for this customer segment
also, such as its “Socks for Everywww.naigai.co.jp/enone”（みんなのくつした）brand.
