About

About LIFE SIDE

LIFE SIDE is a glove and sock brand made by WORLD GLOVE Co., Ltd. in Kurume, Fukuoka. Its founder, Kazuhiko Honda, grew up in a family that made work gloves, and started the company in 2007. LIFE SIDE uses its own yarn, made by bonding collagen onto Japanese-made nylon, on the inside where the fabric touches the skin, and pairs it with washi (Japanese paper) yarn or merino wool on the outside. Every piece is knitted at partner factories in Japan. The name means "things that sit by the side of everyday life", and the brand sets out to make the things you wear every day a little more comfortable.

Concept

A different yarn
inside and out.

The soles of the feet have no sebaceous glands but many sweat glands, so heels can feel dry while feet still get sweaty. To work with that contradiction, LIFE SIDE knits two yarns with different properties together: one on the inside, touching the skin, and one on the outside, facing the air.

Editor’s note

From the editor

October 2026
Worn in hiking boots on Mount Tsukuba

I walked all day on Mount Tsukuba and never once felt my feet get sweaty.

Sitting on the grass in five-toe socks, tying a pair of shoes

I met Mr Honda in October 2026 at the Medical Japan trade fair at Makuhari Messe, where he gave me a pair of Arquitect Merino Wool five-toe socks (light grey and yellow, size L), with collagen-treated yarn on the inside and merino wool on the outside. Later, I wore them for hours inside my hiking boots on a climb up Mount Tsukuba. The first thing I noticed was the comfortable fit around the arch. And although my feet tend to get sweaty, they never felt sweaty at all, even after a hard day of walking. They stayed dry and comfortable from start to finish. Afterwards, I bought a pair of the Washi Yarn Tabi Socks I had been curious about (charcoal black, size L). Those, too, felt so comfortable after a full day in shoes that I could still feel how dry my skin was. From helping at his father's glove factory as a boy to how the yarn works, Mr Honda answered every question carefully in his own words.

For a first pair Choose by season: the washi "Cool" or the "Merino Wool". For split-toe socks, try the washi "Tabi Socks".

What makes it special

01 Close-up of a glove knitted with collagen-treated yarn

A durable nylon yarn with collagen bonded to it

Ask anyone in the world to name a luxury yarn, says Mr Honda, and they will say silk, then wool. Both are animal fibres that keep humidity comfortable, and protein plays a part in that. So LIFE SIDE bonds collagen, a protein, onto strong Japanese-made nylon yarn using a special technique. The result holds humidity in a similar way to silk or wool, but it is far less delicate than silk, lasts a long time and needs no special care in the wash.

The inside is always collagen-treated yarn, while the outer yarn changes with the season. For everyday wear there is "Cool", knitted with highly absorbent washi (Japanese paper) yarn. For colder months there is "Merino Wool", knitted with extra-fine merino of 15 microns or less. The merino has the scales removed from its surface, so it feels less itchy and is less likely to shrink in the wash. The name combines "aruku" (to walk), "tect" (technology) and "architecture".

A collagen finishing technique ten years in the making

Believing that good products need a technique no one else has, Mr Honda spent around ten years developing a collagen finishing process with the Fukuoka Industrial Technology Center's Chemical Fiber Research Institute. It applies collagen to the finished knitted product rather than the yarn, and a patent application has been filed jointly with Fukuoka Prefecture. The first new products made with it are a seamless nightcap and belly band, knitted on WHOLEGARMENT machines.

Four years of Fukuoka Design Awards

The brand is guided by "three Fs": Function, Fun and Fashionable. Beyond function, it aims for things that lift your mood when you wear them, in colours and shapes you want to use every day. From an Encouragement Award for its first product, the Moist Coat glove, in 2010, to a Guest Judge Award for the Arquitect Cool socks in 2013, LIFE SIDE received a Fukuoka Design Award four years running.

Growing up in a glove factory

Kazuhiko Honda's family business made work gloves. Every day after primary school, he spent about two hours helping at his father's factory. Work gloves were essential for all kinds of jobs, but they added little value, and even as a child he felt it was a trade in decline. Still, he believed that adding function would create value and make something people were glad to use. With that belief, he founded WORLD GLOVE in June 2007.

"Gloves we can wear every day"

The company began as the sole Japanese distributor of work gloves made by a British manufacturer, containing ingredients for the skin. Customers who used them asked for gloves they could wear in everyday life. While researching online, Mr Honda found underwear knitted from fabric containing collagen. He contacted the company and explained that knitted gloves need yarn rather than fabric, and they agreed to make a trial collagen yarn.

He knitted gloves from that yarn and asked around twenty women he had never met to try them. The response went far beyond his expectations. After refining the design and function, the gloves became the Moist Coat. Collagen-treated yarn sits on the inside, while coloured yarn is knitted in a raised pattern on the outside, making the gloves both fun to look at and less slippery. He also designed the cuff so it is less likely to leave marks on the wrist, and offered a range of colours that is enjoyable to choose from. When the gloves won a Fukuoka Design Award, he was overjoyed to know his work had been on the right track.

By the side of everyday life

From gloves, the range grew to five-toe socks, always built around the yarn that touches the skin. The brand name LIFE SIDE carries the meaning "things that sit by the side of everyday life". Its tagline, "A little better than bare skin", expresses the hope that people can feel comfortable every day simply by wearing them, without having to think about it.

Made with Japan's knitting factories

LIFE SIDE products are knitted at factories in Japan. Mr Honda says Japan's knitting factories all have high levels of skill and quality. Yet ageing equipment and the retirement of skilled craftspeople are causing knitting, dyeing and yarn-twisting factories to shrink or close.

"Once something is lost, bringing it back is extremely hard. A stable environment for production is essential to Japanese manufacturing."

Kazuhiko Honda, President, WORLD GLOVE

By combining WORLD GLOVE's finishing techniques with the factories' skill, the brand makes products that are truly its own.

From Kurume, to Japan and beyond

Until now, LIFE SIDE has mainly sold through lifestyle and gift shops, but the company is now developing products for the medical and care sectors. In 2026, sales began in the market for older people in China. Kurume University has set up a sleep lab to measure sleep data, and the company will receive support there to collect data on collagen-treated underwear, with prototypes in preparation.

Alongside his work, Mr Honda takes part in clean-up activities on the Chikugo River that runs through his hometown, and he is a member of Chiggotal, a group of makers from the Chikugo region. He says he wants to prove that a small regional company can do business overseas. From a small company in Kurume, he is working to share the comfort of the yarn that touches your skin, both in Japan and around the world.
