The indigo jinbei that needs no trim to stand out
Indigo runs deep in Japanese clothing — it's the colour of workwear, of old dye vats, of cloth that gets better with age. The seikon jinbei leans entirely on it: a rich, even indigo homewear set with no contrast edging at all, letting that single deep blue carry the whole piece. Sometimes the strongest choice is the simplest one.
The colour does all the talking, and the fabric backs it up. Crinkled cotton gauze gives the indigo a soft, textured surface that catches light unevenly, so the blue looks alive rather than flat — closer to dyed cloth than printed colour. It's light and breathable in the heat, and like all good indigo it only deepens in character the more you wear it.
It's a matching two-piece: a wrap jacket that ties at the side with inner and outer cords, paired with relaxed trousers in the same breathable weave. There's nothing to fasten but the ties, so it sits easy on the body whether you're lounging, reading or sleeping on a warm night at home.
This is homewear at its most honest. No trim, no motif, just deep indigo and soft cotton — the set you change into to unwind and to sleep. It's the kind of plain, beautiful piece that makes downtime feel a little better without asking for any attention.
This is for the person who loves a deep, honest indigo and wants it unadorned, for relaxing and sleeping at home — pure colour and soft cotton, nothing else. These run small, so we recommend sizing up for a comfortable, roomy fit.

Good to know
-
Our pieces are cut to Asian sizing, which runs smaller than US sizing — so as a rule, order one size up from your usual size. The exceptions are t-shirts and hoodies, which run true to size, so take your usual size for those. Every product page has its own size chart with exact measurements taken flat, so you can compare against a piece you already own. Still caught between two sizes? Email support@japan-clothing.com and a real person will help you pick the right one.

Materials vary from piece to piece — some are 100% cotton, others polyester, satin-finish, or a blend, depending on the design. You'll find the exact composition in the product description above, and it's always printed on the inner label of the garment itself. When the two ever differ, trust the label.
A little care goes a long way with these pieces. To keep colors deep and fabric intact:
- Machine wash cold, 30°C / 86°F maximum — heat is what fades and shrinks
- Turn the garment inside out and wash with similar colors
- Use a gentle cycle and mild detergent; skip the fabric softener on printed or embroidered pieces
- Do not bleach
- Hang to dry in the shade — avoid the tumble dryer, which is the fastest way to ruin the fit
- Iron on low heat if needed, and always inside out over prints or embroidery
- For anything delicate or unusual, follow the inner label first
Treated right, these pieces hold their shape, color and detail wash after wash.

Japan Clothing is inspired by Japan, not made in Japan — and we'd rather you hear it from us. Every piece draws from Japanese culture, design and street style: the energy of Tokyo's backstreets, the calm of a Kyoto workshop, the prints of vintage textiles, the cut of modern streetwear. We translate that inspiration into clothes built for daily wear, anywhere in the world.
The pieces themselves are produced by manufacturing partners in Asia. The exact composition of each one is listed on its product page and printed on the inner label — no guesswork, no fine print.
We don't sell you an origin. We share a spirit.
