“I needed to create denims that might at some point return to nature,” says Oikawa. “After dropping a lot to the ocean, I started to suppose deeply about how we dwell with it — how we are able to make issues with out harming it.”
These pure “scraps” from sea and land, as soon as destined for disposal, are actually reworked by expert processors and seamsters in Kesennuma into distinctive denims which have gained followers in Japan and abroad.
“The completed denims really feel similar to 100% cotton,” Oikawa explains. “And since swordfish payments comprise a lot calcium phosphate, denim spun with that powder retains moisture higher than standard cloth.”
Even the fragments left over from yarn-making are carbonized and used as dye, leading to zero waste. The blue-gray hue of the denim echoes the swordfish itself, completely reflecting Oikawa’s philosophy: a fusion of sustainability, craftsmanship, and respect for nature’s cycles.
Life-changing encounters in a shelter
Due to its high-end craftsmanship, Oikawa Denim has earned a loyal following abroad, even producing reissues for world-famous manufacturers.
Oikawa credit a chronic keep in an evacuation shelter for fully altering his outlook on life. “I had cash in my pockets, but couldn’t purchase even a single bottle of water,” he remembers. “It compelled me to rethink what cash actually is.”
Shelter life additionally introduced him into contact with individuals from many trades. Via dialog, he realized how a lot he didn’t know in regards to the work taking place proper in Kesennuma.
“A lot of what I heard about work at sea was new to me,” he says. “Studying that the payments of our native specialty, swordfish, have been merely lower off and discarded into the ocean felt unsuitable.”
He added: “Had I not lived by that earthquake, I most likely would have simply nodded and moved on. Fishers threat their lives at sea to convey again these fish. Relatively than throw components away, couldn’t we honor them by placing them to make use of by our work?”
With that conviction, the problem of creating “swordfish denim” started.
Dedicated to pure supplies that return to the earth
At present, practically all uncooked supplies for denim produced in Japan are imported. Oikawa noticed an opportunity to vary that.
“If what was being discarded can grow to be clothes materials, we are able to make higher use of sources and likewise assist fishers by buying the fabric,” he says.

Miyagi Prefecture boasts Japan’s largest swordfish catch, and Kesennuma Port will proceed to land high-quality fish by round March. The rapier-like invoice can attain a few meter in size. As a result of it’s unwieldy and may harm the fish when landed, it’s often lower off on deck and discarded. At Kesennuma alone, greater than 40 tons are thrown away every year.
At Oikawa Denim, the bought payments are pulverized and utilized in spinning.
“A whole bunch of cotton fibers — every with a hole, macaroni-like construction — are twisted right into a single yarn. By filling these hollows with powdered payments, we are able to scale back the cotton content material by about 30%,” he explains.

Denims constituted of swordfish denim are composed fully of pure supplies that absolutely return to the earth. Together with the bill-infused cloth, they use coconut-shell buttons, avoiding metallic rivets, metallic buttons, and zippers altogether.
In manufacturing, Oikawa follows the ethic etched into him throughout shelter life: administration that doesn’t tilt towards profit-seeking. His aim is a sustainable system the place everybody — from fishers and grinders to carbonizers, spinners, dyers, and weavers — advantages, fairly than ramping up mass manufacturing just because gross sales are sturdy.
For that cause, annual buying is capped at about 1 to 1.5 tons of payments, and manufacturing at 1,000 to 1,500 pairs of denims.
“This isn’t a flash-in-the-pan enterprise — the purpose is to maintain it going. We set our manufacturing quantity from the outset. Swordfish denim is, in a way, a problem aimed toward creating a greater cycle for the long run.”

Pushed to encourage younger minds with the artwork of sustainable creation
After the success of the swordfish invoice denim, Oikawa continued to innovate along with his efforts to recycle supplies. Since 2015, he has expanded his work to incorporate denim constituted of deer hair, a cloth as soon as thought of a nuisance. “The hair from culled deer has no use and is dissolved with chemical compounds and discarded,” says Oikawa. “It’s not nearly recycling waste; I hope that through the use of deer hair denim, it’ll immediate individuals to suppose, ‘Why have the deer that must be culled elevated a lot?’”
“I wish to share the enjoyment of making issues with younger individuals,” he provides, emphasizing his need to show the following technology about sustainable innovation.

The challenge has now moved from “sea” to “land,” and the remaining “mountain” part is underway: crafting denim from supplies they develop themselves.
“We’re nonetheless prototyping,” Oikawa says. “However we’re cultivating grapes, turning the vines into fiber for yarn, and dyeing the denim with the juice.”
For him, “there’s nothing in nature that may’t be used.”
He provides: “I desire a society the place failure isn’t taboo and other people can hold making an attempt. To that finish, we’d like environments the place the younger — who will form the long run — can study the backstory, the method, and the enjoyment of creating issues.”
