Landing a job in Japan is exciting — and yet many newcomers worry that a single wardrobe slip‐up could undo weeks of relationship-building. The good news? Japanese office attire follows a clear, almost formulaic logic. Master the rules below and you will project competence and cultural respect from day one.
Why Appearance Matters in Japanese Offices
First impressions in Japan rest heavily on visual harmony. Colleagues see a neat, subdued outfit as proof that you value the team over individual flair. Even in companies that celebrate innovation, dressing too casually in client-facing settings may be read as poor self-discipline, rather than creativity.
Respecting the Collective
Uniform-like suits symbolize alignment with group goals. This stems from the broader cultural norm of wa — maintaining social equilibrium by avoiding elements that “stand out too loudly.”
Building Your Core Wardrobe
Begin with the safest baseline, then adapt once you understand your firm’s rules… which may be unwritten!
Men’s Essentials
- Suit: Single-breasted, in navy or charcoal, with subtle pinstripes at most.
- Shirt: Crisp white or pale blue.
- Tie: Never wear a black tie (as it has funetarial connotations), instead choose muted stripes or dots, with the tie itself being under 8cm wide.
- Shoes and Socks: Mirror-shined black Oxfords, with dark socks long enough to hide a bare calf when seated.
- Bag: One should carry slim leather briefcase, as large backpacks read as student-like.
Women’s Essentials
- Suit: Tailored skirt, or trouser-suit in the same navy–charcoal spectrum, with the hem touching the knee when standing.
- Top: Opaque, light-colored blouse — no sheerness, frills or plunging necklines.
- Footwear: Closed-toe pumps with a heel under5cm, andbeige stockings remain standard even in midsummer.
- Bag: One understated leather tote in black or tan.
Tip: Japanese elevators often have mirrors near the doors, which make themideal for a final collar or hair check before stepping out.
Seasonal Adjustments: Cool Biz & Warm Biz
Since the Ministry of the Environment launched the Cool Biz movement in 2005 to cut air-conditioning costs, many offices relax their code from May to September. Ties come off, jackets become optional and short-sleeved shirts appear — however, prints stay muted. In winter, Warm Biz encourages thermal layers under the same dark suit to reduce heating. Always confirm with HR before ditching your tie, and remember that client meetings override seasonal leniency.
Grooming and Accessories
Even a ¥100,000 suit loses credibility beside uneven stubble or chipped polish.
Hair, Face & Hands
- Hair color: Keep to natural shades until you gauge local tolerance.
- Facial hair: Either clean-shaven or sharply trimmed daily.
- Nails: Short, clear or nude; neon art can spark unwanted comments.
- Fragrance: One discreet spritz max. Many professionals skip perfume altogether.
Functional Minimalism
- Jewelery: A wedding band and an analogue watch are sufficient for men. Women may add small ear studs or a necklace that stays silent when typing.
- Tech Accessories: Neutral laptop sleeve; cartoon phone cases belong off-duty.
- Shoes Etiquette: Replace worn heels promptly; scuffs suggest carelessness.
When the Rules Relax
Outside of banks and trading houses, dress codes vary… yet tidiness still defines professionalism.
Tech Start-ups and Creative Studios
Dark jeans or chinos with a collared shirt and blazer are often passable. Sneakers must be spotless and ideally be free of logos. Reserve graphic tees until you see the CEO sporting one.
Business Casual Days
If HR specifies “business casual,” then you should stick to the standard style: tailored trousers, leather shoes, and a pressed shirt. Fine-gauge knitwear can replace a blazer in winter, but hoodies? No, no, no!. Stash a jacket at your desk for sudden video calls with headquarters.
Remote Meetings
Japanese colleagues frequently screenshot online sessions for minutes. A crisp collar, neutral backdrop and good lighting maintain authority, even from home.
Quick Pre-Meeting Checklist
- Suit pressed and lint-free?
- Colors conservative and coordinated?
- Hair neat, nails clean, scent subtle?
- Shoes polished, heels intact?
- Correct stance on Cool Biz for today?
- Backup blazer or tie in your bag?
Default to overdressing until office norms become clear. A measured, unobtrusive style lets your ideas — not your outfit — take centre stage.
