Why Is a Long-Established Knit Factory Creating Its Own Brand? Mitsumoto Textile's "Amyto" Challenge

Mitsumoto Textile, a knit manufacturer with over 150 years of history based in Mitsuke City, Niigata Prefecture, has launched its first factory brand, "amyto" (pronounced ah-mee-to). For years, the company supported manufacturing primarily through OEM business. Behind their decision to launch their own brand is a desire to convey the value of accumulated skills and experience in their local textile region directly to consumers in their own words. What do they hope to share through "amyto," and how do they envision the future of this craft region? We spoke with product manager Nozomi Matsuura.

Expressing Craftsmanship Value in Their Own Words—Something OEM Couldn't Fully Convey

Mitsumoto Textile has crafted knitwear for numerous brands through OEM production. Because of this, they were confident in their technical expertise and dedication to craftsmanship. However, remaining behind the scenes as a contract manufacturer created an internal conflict: they couldn't directly communicate their true value to customers in their own words.

"Take care labels, for example. Sometimes 'Mitsumoto Textile' is listed as the manufacturer, but other times our name doesn't appear at all."

Even when creating exceptional products, their name often remained hidden. This frustration led to deeper questions: "What values do we prioritize in our craftsmanship?" and "How can we preserve these techniques for the next generation?"

Their answer was launching their own in-house brand, "amyto." By handling everything from planning and manufacturing to sales, they can infuse their accumulated craftsmanship into materials and designs, rather than relying solely on specifications dictated by client brands.

The brand name "amyto" comes from ami-ito, the Japanese word for "knitting yarn." As the name suggests, the brand's craftsmanship starts with the yarn itself.

"We don't view yarn as just a raw material, but as the starting point of craftsmanship that determines a product's look, comfort, and durability. Even with the exact same knit design, changing the combination of yarn material, thickness, or twist dramatically alters its texture, drape, and warmth."

This philosophy is clearly reflected in the "PLAID CARDIGAN" from their debut collection. Initially, they aimed for 100% mohair to achieve a rich, fluffy texture. However, attempting to knit a 100% mohair fabric on a specialized knitting machine caused holes in the fabric and caused the machinery to stop mid-process.

"Rather than giving up on mohair, we asked ourselves how we could retain its characteristic long fibers and unique texture while maintaining stable production. We added wool for warmth, and acrylic and nylon to provide strength and stability. It wasn't just a matter of mixing them together; we knitted sample after sample, adjusting the ratios while observing the condition of the yarn and the machine's performance. That's how we arrived at this final blend."

29% wool, 23% mohair, 23% acrylic, and 25% nylon. These precise numbers were the result of repeated trial and error balancing ideal texture with practical manufacturing limits.

Repeatedly adjusting yarn combinations and blend ratios to achieve both ideal texture and stable production—this dedication embodies amyto's approach of making yarn the starting point of craftsmanship.

Mitsuke was originally a textile weaving center that gradually transitioned to knitwear manufacturing over time. Although extensive technical expertise has accumulated over many years, what Matsuura refers to as the "value of the craft region" cannot be seen from machinery or specification sheets alone.

"When knitting with machines, having a different operator can produce a completely different result. Unless you thoroughly understand the yarn's condition and the machine's characteristics, you won't get a finished product of proper quality."

Yarn expands in higher temperatures and contracts in lower temperatures, becoming harder to work with. Even for the exact same item, machine settings vary depending on whether it is knitted in summer or winter. Making these subtle calls requires seasoned artisans. Matsuura believes that this judgment, rooted in years of hands-on experience, is the true core strength built up in Mitsuke.

Supporting the pattern expression of "amyto" is the "LAPIS Intarsia Warp-Insertion Hybrid Flat Knitting Machine," of which only a few are said to exist in Japan. Flat knitting machines originally knit by moving yarn horizontally. Because this machine can insert warp threads simultaneously, it can achieve a thinness and flat knit texture that standard flat knitting machines cannot produce.

However, achieving that quality requires a substantial amount of time and effort. Setting up the warp threads alone takes anywhere from half a day to two days, even for a skilled technician. What's more, only one person in the company can operate this machine. If that technician takes time off, production comes to a complete halt. Considering only production efficiency, it is by no means an efficient approach.

"We aren't simply chasing pure production speed. Rather than cutting down time, creating products that are worth taking the time to make is core to amyto's philosophy and commitment."

That said, Matsuura stresses that they are not rejecting efficiency altogether.

"We should dedicate time where it's truly needed, and streamline what can be streamlined. That kind of balance is essential for the future of manufacturing."

That is precisely why plans are moving forward for other technicians to learn how to operate this machine—to pass down technical skills and enhance the stability and flexibility of their production setup.

Harnessing Regional Craftsmanship in the Modern Era

Serving as amyto's product manager is Matsuura, who joined the company in April 2024. Although she studied design at university, her knowledge of knitwear production started from scratch. She admits being surprised when she was first entrusted with the brand.

"Things that long-time technicians on the factory floor take for granted are often actually valuable skills and insights. My priority is to see them with my own eyes and truly understand them.

On top of that, I see my role as figuring out how to connect those techniques with contemporary design, modern lifestyles, and the values of today's consumers."

Connecting the everyday techniques and insights of technicians to modern design and lifestyles as the inherent value of the region—this is Matsuura's role at amyto: bringing the craftsmanship accumulated in Mitsuke into contemporary manufacturing.

The concept behind "amyto" is "Modern Heritage"—reinterpreting inherited techniques and craftsmanship through a contemporary lens. How does amyto view a garment built upon such accumulated time and technical skill? It reflects a unique perspective on luxury that cannot be measured by price or material rarity alone.

"It's not simply about using expensive materials or setting a high price tag. We believe that value accumulates within a single garment through time, craftsmanship, materials, and human wisdom."

What's more, this value doesn't peak the moment you buy it; it becomes richer the more you wear it. amyto aims not just to elevate its own brand value, but to prove that factories in regional manufacturing hubs can launch their own brands and deliver their accumulated skills directly to consumers.

"One goal is to show a working example where the manufacturing region itself takes the lead in creating a brand. Japan has many highly skilled factories and artisans, yet in most cases, that value never reaches the consumer."

Looking beyond the brand itself, they have their sights set on the future of the entire region.

"Ultimately, we want to make this a region where young people feel inspired to pursue craftsmanship or make knitwear here in Mitsuke. Our goal isn't just for 'amyto' to succeed on its own, but to create an environment where the brand's growth drives the growth of the community and region."

Taking half a day to two days just to thread the warp. Adjusting machines according to yarn condition and temperature—decisions that only seasoned technicians can make. In the knitwear hub of Mitsuke, skills and experience that cannot be measured by numbers or production efficiency alone have accumulated over many years.

Rather than keeping that value locked inside the factory, Sanbon Textile launched "amyto" to communicate it directly to consumers in their own words. Communicating regional craftsmanship through an in-house brand and passing it on to the next generation—that is why this long-established knit factory chose to build a brand of its own.
