How to put it together
- 1
Put on a lightweight, breathable base layer of clothing like a t-shirt and shorts.
- 2
Insert fresh AA batteries into the inflatable suit's fan pack.
- 3
Step into the inflatable sumo suit, pulling it up to your shoulders and securing the neck, wrist, and ankle bands tightly to prevent air from escaping.
- 4
Turn on the fan switch and clip the battery pack to your waistband or pocket inside the suit.
- 5
Allow the suit to fully inflate, which should take about one to two minutes.
- 6
Place the black topknot wig or headpiece securely on your head.
- 7
Practice your best wide-legged sumo stance and stomping motions.
Makeup & hair
Keep makeup minimal or clean. If you are not using a wig, style long hair by pulling it tightly into a high, sleek bun at the top of your head, folding the tail forward to mimic a traditional chonmage.

Sumo Wrestler costume FAQ
- How does the inflatable sumo costume stay inflated?
- The costume features a small, built-in electric fan that clips to your belt or pocket. It runs on AA batteries and continuously blows air into the suit to keep it fully expanded.
- Can I sit down while wearing an inflatable sumo suit?
- Yes, you can sit down, but the suit will temporarily deflate or compress. It will quickly reinflate once you stand back up.
- What should I wear underneath the sumo suit?
- Wear light, moisture-wicking athletic clothes like a t-shirt and shorts, as the plastic material of the inflatable suit can trap body heat.
Did you know? The traditional hairstyle worn by sumo wrestlers is called a chonmage, which was originally designed to keep samurai helmets secure during battle.
