What to wear to a sumo show in Osaka
No dress code
You can wear jeans, casual clothes, whatever is comfortable. Sumo shows and tournaments are not formal events with a dress code. Comfort is the priority.
The colour myth
There is no rule against wearing black or dark colours in Japan. This is a myth. Wear whatever colours you like. Ordinary, everyday clothes are all fine.
Floor box seats (tournament only)
If you're in a masu-seki (tatami box on the tournament floor), you sit on cushions, so easy-to-remove shoes help. Slip-on shoes, loafers or sandals are good. You'll take your shoes off in the box and sit on the floor. Comfortable, easy-to-fold clothing is nice but not required.
Shows at venue locations
Shows are indoors at proper venues. Regular casual clothes work. No special gear needed.
What to avoid
Very revealing outfits or outlandish clothes are fine in Western contexts but show courtesy in Japan. Otherwise, go with comfort and ease.
