MADE IN ASIA. — PROVEN BY DATA.

Global-standard uniforms,
made for Japan's workplaces.

W — WEARER

Designed around
the people who wear it.

The people on site put it on every day. We start from freedom of movement and long wear.

I — IDENTITY

What you wear
is how you're seen.

What is it for? How does it look from outside? Color and form follow your company's strategy.

S — SERVICE

Designed beyond
the moment it's worn.

Distributing, restocking, repairing, returning. Records by style, color and size support every reorder and repair.

E — EARTH

Up close,
still one fabric.

The main fabric is mono-material. With no blends, it is designed to be easier to recover without separating fibers.

Our Services

Uniforms — made, presented, managed.

A uniform is never a one-off. Every new hire and every transfer brings another order. KEIF designs both sides: making the uniform, and running supply and reorders afterwards. From rollout to day-to-day operations, it runs through one partner.

  1. Ready-made styles developed by KEIF, or made-to-order uniforms designed from scratch for your company.

Record — Digital Product Passport

Technology that makes information trustworthy

Since 27 September 2026, the EU has prohibited environmental claims that cannot be substantiated. In Japan, sustainability disclosure — including emissions from purchased goods (Scope 3) — is being phased in from the fiscal year ending March 2027, starting with the largest Prime Market companies. Uniforms fall within that scope. In both the EU and Japan, companies are increasingly expected to back up environmental claims with evidence.

Green claims, meanwhile, are easy to write. A plausible explanation no longer counts as evidence. What matters is who recorded the information, when, and whether it can be checked later.

KEIF issues a DPP for every style, color and size, and records where and by whom each product was made on a blockchain (chaintope's Tapyrus), so it can be checked later that nothing has been changed. The records are built to support explanations to business partners and formal disclosures.

The rest is on each product's DPP, via its QR code: the CO₂ estimate, care, and the proof and record.

Network — Japan and Taiwan

Across Japan and Taiwan, responsible for materials and records.

KEIF plans and develops. Material technology comes from Taiwan; recording technology from Japan. We develop our products with Singtex in Taiwan, and the record system with chaintope in Fukuoka.

Comfortable and long-lasting. Traceable, repairable, recoverable. We divide the roles to deliver both at once.

Sustainability

Building something that lasts — in our generation.

Anyone can say a product is good for the environment. What KEIF can show is the evidence.
What standard do we use to call something sustainable, and how much can we actually record?
Everything we decided at founding is on one page.
