Attending a sumo wrestling tournament is a quintessential Japanese cultural experience, but choosing appropriate attire requires understanding both the climate conditions and the etiquette expectations of this traditional sport.
👔 General Dress Code Principles for Spectators
There are no rigid regulations on what spectators can wear to sumo matches—both Japanese and Western-style clothing are acceptable. However, out of respect for Japan's national sport and its long historical traditions, you should avoid extremely casual, revealing, or flashy clothing.
✅ DO Wear
- Smart casual attire
- Business casual clothing
- Traditional Japanese clothing (kimono/yukata)
- Neat, comfortable outfits
- Outlandish or flashy outfits
- Short mini-skirts or revealing clothing
- Tight skinny jeans (especially for floor seating)
- Large hats that obstruct others' views
- Beach wear or activewear
Many Japanese spectators dress neatly for the occasion, with women often wearing kimonos or formal attire and men sporting suits, reflecting the cultural significance of the event.
🪑 Comfort Considerations for Extended Viewing
Sumo tournaments are all-day events that can last several hours (see our complete tournament timeline), and comfort is crucial. The type of seating you've chosen (check our seating guide) significantly impacts your clothing decisions.
🎎 For Masu-Seki (Floor Cushion Seating)
If you're sitting in traditional floor cushion seating, you'll need to remove your shoes and sit cross-legged for extended periods. For this arrangement:
- Avoid constrictive clothing
- Choose comfortable pants that allow freedom of movement
- Avoid tight jeans - opt for loose-fitting elastic pants or long skirts
- Wear easy-to-remove shoes (avoid complicated lacing)
💡 Pro Tip
Those who find floor seating challenging should choose arena seats with regular chairs instead. See our Best Seats Guide for comparisons.
🪑 For Arena Chair Seats
Regular Western-style seating offers more flexibility in clothing choices, but you'll still want comfortable attire for several hours of viewing.
🌡️ Seasonal Clothing Guide
❄️ Winter (January Tournament)
The January basho takes place during Tokyo's coldest season, with temperatures ranging between 2-9°C (36-48°F). The Ryogoku Kokugikan is heated, but the venue can still feel chilly before crowds arrive.
🧥 Winter Outfit Recommendations
- Base layer: Thermal undershirt
- Mid layer: Sweater or long-sleeve shirt
- Outer layer: Medium to heavy coat (you can remove once inside)
- Accessories: Scarf, gloves, boots
Key Strategy: Wear breathable, layered clothing rather than a single heavy coat. The stadium's air conditioning kicks in once crowds build, so layers allow you to adjust throughout the day.
🌸 Spring (May Tournament)
Spring weather is unpredictable with temperature fluctuations throughout the day. Temperatures are generally mild around 15-20°C (59-68°F).
🧥 Spring Outfit Recommendations
- Base: Long-sleeved shirts
- Layers: Lightweight jacket, cardigan, or hoodie
- Rain gear: Umbrella or light rain jacket (late May brings showers)
- Strategy: Multiple light layers for flexibility
🍂 Autumn (September Tournament)
September marks Japan's transition from hot to warm weather. Weather is still relatively warm, but evenings cool significantly.
🧥 Autumn Outfit Recommendations
- Daytime: Short sleeves and light fabrics
- Evening: Long sleeves, light hoodie, windbreaker
- Rain gear: Umbrella or light rain jacket (September is rainy season)
- Late September: Add lightweight sweaters as temperatures drop
