About
About ICHORA⁺
ICHORA⁺ is a T-shirt brand made at its own factory in Odate, Akita. The name comes from the Japanese word itchōra, the one best outfit a person owns. ZOOM Co., Ltd., a sewing company founded in 1980, launched its own brand, ICHORA, in 2012, and added ICHORA⁺, with functional materials, in 2024. It is wear for adults who want to age beautifully and in their own way. Clothing touches the skin for much of the day, so the idea is to reduce even the small stresses that come from how a shirt feels. The fabric is 90% cotton and 10% rayon, sewn in three dimensions to follow the body and garment-washed so that its size and feel last. Spinning, knitting, dyeing and sewing are all done in Japan, and each quality label is stamped with the seal of the person responsible for making it. The goal: to make Japanese-made T-shirts a movement.

Concept
Your best outfit,
plus function.
For a brand made in Japan, it felt right to choose a Japanese word that also sounds beautiful: ICHORA, from itchōra, the one best outfit a person owns. The plus sign, added in 2024, stands for functionality as a new kind of value. The aim is a T-shirt that reduces the small stresses of what touches your skin every day.


A sewing factory in Japan planning, making and selling under its own name.
Curefilo, a material that may be expected to help with relaxation and easing stress.
A shirt for feeling good and making daily life more comfortable.

What makes it special
Functional yarn built on rayon, not polyester
The fabric is 90% cotton and 10% rayon, made with curefilo from Maruyasu Keito Co., Ltd., a material using plant-derived ingredients from Japanese knotweed, mugwort and persimmon leaves growing wild on hillsides across Japan, under contract with the people who manage the land. Because the plants are wild, no pesticides are used. Because the functional ingredient is applied to rayon rather than polyester, the fabric stays centered on natural fibers and soft to the touch. Curefilo is not designed to boost circulation. ICHORA⁺ chose it in part because it may be expected to help with relaxation and easing stress.
Three-dimensional sewing and a difficult garment wash
The patterns are drafted in three dimensions so the shirt follows the thickness and curves of the body. Each finished shirt is then washed in a process calculated around the different rates at which the fabric shrinks lengthwise and widthwise. Few sewing factories take this on. The aim is that the feel and size you bought are still there after washing at home, and it draws on skills built up over years of sewing for other brands.
Tags and labels kept off your skin
Side-seam care tags and neck labels are a common complaint: they touch the skin and scratch. ICHORA⁺ quality labels are sewn so they come away easily once the stitches are undone with a fine tool, and the brand name is printed rather than sewn in as a tag. Small discomforts, removed one at a time.
From summer sun to a warm winter blanket
Curefilo T-shirts take a different approach from conventional recovery wear designed to promote blood flow, so they do not feel hotter than they need to, whether in summer or under a warm blanket in winter. They are cut loose rather than compressive, which also suits unwinding or sleeping. Wear one on its own in summer, or layered under a shirt or loungewear in winter.
A shirt for brutal summers, in washi fiber and cotton
From the ICHORA line comes a T-shirt made for extreme heat. It pairs the lightness and dry touch of washi (Japanese paper) fiber with the softness of cotton. Its best quality is how the light fabric stays off the skin, even in hot weather when a sweaty shirt would otherwise cling.
A maker's seal on every label
Every ICHORA⁺ quality label carries a seal reading Kagamura, the name of the person responsible for making it. The company has held to the same idea since it began as a sewing business: taking responsibility for the clothes it makes. The seal puts that commitment on each shirt that reaches a customer.

Because the sewing factory makes the clothes
ICHORA⁺ is made by ZOOM Co., Ltd., a sewing company founded in 1980 by a clothing designer. A factory followed in 1993 in Odate, Akita, a city home to many apparel factories, and from 1996 all production was consolidated there.
For decades, the factory worked mainly as a contract sewer for other brands. But labor and other costs kept rising. Rather than rely on contract work alone, the company decided to plan, make and sell its own brand and keep going as a sewing factory in Japan. The result, in 2012, was ICHORA.
The name comes from the Japanese word itchōra, the one best outfit a person owns. For a brand made in Japan, it felt right to choose a Japanese word that also sounds beautiful.

"In the end, it's the sewing factory that makes the clothes. That's why I want to take responsibility for the clothes I make."
Made for what touches your skin every day
On March 15, 2024, ICHORA added functional materials and became ICHORA⁺. Clothing touches the skin for much of the day, so reducing the small stresses of how a garment feels has real meaning. Not just clothes that look good, but clothes that feel good and make daily life more comfortable: that is the thinking behind ICHORA⁺.
Behind that thinking is what company president Moto Kagamura learned as a pharmacist about how stress affects body and mind. The phrase "from medicine, to clothing, to clothes that care" became the starting point for the brand. In Japanese, it plays on three words all pronounced iryō-jin: a person of medicine, a person of clothing, and a third written with the characters for clothing and care.
These are shirts for the day, and also for unwinding at home or sleeping, the times when it matters most to put less stress on the body. The hope is that people will choose ICHORA⁺ for themselves, today and tomorrow.


A seal on the label, 44 years on
Starting with ICHORA⁺, each quality label has been stamped with the Kagamura seal, the mark of the person responsible for making it. It had been 44 years since the company was founded, and the factory was now making T-shirts under its own brand. The seal is a way of taking responsibility for every single garment as its maker.
What matters most at the Akita factory is honest work without compromise. Underneath that is an attitude: thinking not "for the customer" but "from the customer's position." Instead of deciding by the maker's own convenience or values, the factory keeps asking how the person wearing a shirt will feel and what they are looking for.


"This is the T-shirt I've been looking for"
Having its own brand changed something at the factory. In the contract-sewing years, the staff almost never heard directly from the people who wore what they had made.
Then a customer told ICHORA⁺: "This is the T-shirt I've been looking for." When those words were passed on to the Akita staff, people began to feel that "maybe what we do is actually something remarkable." Skills and work they took for granted had become something special to someone else. Customers' voices helped the craftspeople see the value of their own work again.

Making Japanese-made T-shirts a movement
The white ICHORA⁺ T-shirt is made entirely in Japan, from spinning through knitting, dyeing and sewing. The brand has been certified under Sumida Modern 2025, the regional brand of Sumida City, and in September 2026 it appeared on the ABEMA Prime program to talk about the state of Japan's sewing factories, on the theme "Made in Japan: 1.1%."
The first goal is to be the name people in Japan think of for Japanese-made T-shirts. The larger one is to "make Japanese-made T-shirts a movement," in the belief that the brand's growth can bring more work to Japan's sewing factories and carry its manufacturing into the future. For now, building recognition in Japan comes first, though the company would gladly take on overseas opportunities when they arise.
On December 11 and 12, 2026, ICHORA⁺ plans to take part in the Nihonsei no Kakugo Ten event in Osaka, a chance to feel the shirts in person.
