Latest Office Wear Trends in Japan


Let’s explore what’s hot in Japanese office wear right now:


Suits are Office Wear Trends in Japan

Trend 1: Dark suits (navy, charcoal, black)


  • What it means: A single-breasted suit in navy or charcoal looks professional in almost every office. Keep the design clean, simple pockets, minimal stitching, so it feels timeless and easy to match across seasons.

  • Fabrics: Super 100s–120s wool for drape; tropical/high‑twist wool or wool‑poly/elastane blends for hot commutes and long days; use the same fabric for jackets, trousers, and skirts so colors match perfectly.

  • Colors: Navy and charcoal as the main options; deep grey as an alternative; black mainly for very formal contexts or interviews.

  • Brands in Japan: UNIQLO, AOKI, ORIHICA, THE SUIT COMPANY, Konaka, GU.


Trend 2: Buttoned jackets for women


  • What it means: Women often keep blazers buttoned during meetings, so the jacket should close smoothly without pulling and feel stable at the shoulders. Pattern alignment at the front (for checks/stripes) matters.

  • Fabrics: Stretch wool, suiting twill, or ponte with partial or full lining so it drapes cleanly over blouses and dresses.

  • Colors: Navy, charcoal, gray, black for formal; beige if the office allows business‑casual looks.

  • Brands in Japan: UNIQLO, PLST, IÉNA, Tomorrowland.


Knee touching shirts are Office Wear Trends in Japan

Trend 3: Knee-touching skirts


  • What it means: The hem should touch the knee when standing and remain modest when sitting. A back vent and lining help the skirt move without riding up or clinging.

  • Fabrics: Lined suiting twill, stretch crepe, and stretch wool; consider anti‑static lining for smoothness.

  • Colors: Navy, charcoal, black, medium grey; very subtle pinstripes if the office is formal-friendly.

  • Brands in Japan: AOKI, ORIHICA, UNIQLO, United Arrows.


Trend 4: White and pale shirts/blouses


  • What it means: White, light blue, or pale pink shirts and blouses look clean under jackets. Focus on opaque fabric, crisp collars, and easy‑care finishes that hold up after frequent washing.

  • Fabrics: Poplin, twill, pinpoint oxford with slight stretch; non‑see‑through is essential.

  • Colors: White, light blue, pale pink, very light gray; add micro‑stripes for interest without being loud.

  • Brands in Japan: UNIQLO, GU, AOKI, THE SUIT COMPANY.


Cool biz shirts and dresses are Office Wear Trends in Japan

Trend 5: Cool Biz shirts (summer)


  • What it means: In many offices during summer, short‑ or long‑sleeve shirts are worn without a jacket. These shirts should breathe well, manage sweat, and still look sharp without a tie.

  • Fabrics: High‑twist cotton, cotton‑poly blends, moisture‑wicking shirting; seersucker only if the office is more casual.

  • Colors: White, light blue, pale gray; subtle stripes or micro‑checks that remain conservative.

  • Brands in Japan: AOKI (Cool Biz), ORIHICA (Cool Biz), UNIQLO (AIRism shirting/polos for casual offices).


Trend 6: Tailored dresses


  • What it means: Simple sheath or column dresses in neutral tones that layer neatly under a blazer or cardigan. Keep necklines modest and fabric non‑sheer so they read as business‑appropriate.

  • Fabrics: Stretch crepe, ponte suiting, stretch wool blends; half or full lining; add a back vent for mobility.

  • Colors: Navy, black, charcoal, dark beige; deep forest or burgundy if the company allows office casual.

  • Brands in Japan: PLST, IÉNA, Theory (widely stocked in Japan), Tomorrowland.


Fine gauge cardigans are Office Wear Trends in Japan

Trend 7: Fine-gauge cardigans/knit layers


  • What it means: Lightweight cardigans and knits are common over shirts and dresses, especially on office‑casual days or in air‑conditioned spaces. Twin sets (shell + cardigan) make outfitting simple.

  • Fabrics: Fine‑gauge viscose blends, cotton‑silk, merino or washable wool that keep shape after wear.

  • Colors: Navy, black, gray, beige, taupe; soft pastels if the office is more relaxed.

  • Brands in Japan: UNIQLO (Extra Fine Merino), GU, MUJI, United Arrows.


Trend 8: Subtle patterned tops


  • What it means: Micro‑stripes or micro‑dots add subtle interest while still looking formal. Keep contrast low so the pattern reads neat from a distance.

  • Fabrics: Smooth poplin, pinpoint oxford, fine dobby; ensure opacity.

  • Colors: White/blue stripe, gray/white stripe, tiny dots on pale grounds.

  • Brands in Japan: THE SUIT COMPANY, ORIHICA, AOKI, UNIQLO.


Formal outerwear and fit trousers are Office Wear Trends in Japan

Trend 9: Formal outerwear


  • What it means: Overcoats for winter and short trench/raincoats for spring/fall should fit cleanly over a suit. Keep designs minimal so they work with any suit set.

  • Fabrics: Wool or wool‑cashmere for winter warmth; water‑repellent cotton‑nylon or polyester for trenches; removable or button‑in liners for temperature changes.

  • Colors: Black, navy, charcoal for coats; beige or navy for trenches.

  • Brands in Japan: Mackintosh Philosophy (by Sanyo), BEAMS F, United Arrows, UNIQLO (seasonal coats/trenches).


Trend 10: Conservative trouser/slacks fit


  • What it means: Trousers should be straight or gently tapered, not skin‑tight and not pooling at the hem. Aim for a comfortable rise for sitting and a crease that holds its shape.

  • Fabrics: Stretch wool, wool‑poly with elastane, technical suiting with recovery; high‑twist/lightweight blends for humid months.

  • Colors: Navy, charcoal, black, mid‑gray; add light gray in summer assortments.

  • Brands in Japan: AOKI, ORIHICA, UNIQLO (Smart Ankle/Pleated Tapered office styles), THE SUIT COMPANY.


Retailer-friendly tips to go deeper


  • Match sets by fabric and dye lot: For every blazer, offer trousers and a skirt in the same fabric and color so shoppers can build modular wardrobes.

  • Seasonal capsules:

    • Summer: breathable Cool Biz shirts, light grey suits, high‑twist wool trousers.

    • Winter: lined dresses, mid‑ to heavyweight wool suiting, structured overcoats.

  • Fit and length clarity: Put clear guidance on knee‑length skirts and trouser cuts/inseams on tags and online PDPs to reduce returns and meet office expectations.

  • Build bundles: Offer “Workweek Kits” (1 blazer + 2 trousers or 1 trouser + 1 skirt + 3 shirts + 1 cardigan) to simplify buying and encourage multi‑item baskets.


These details help product teams choose the right cloth weight and construction, help buyers plan tight assortments that sell in Japanese workplaces, and help visual merchandisers present clean, confident‑building outfits on floor and online.
