A was a traditional Japanese hunting tool. It was used as an aid when rabbit hunting in the snow.
The name "warada" is a corruption of . Although warada are mainly associated with the matagi hunters of northern Japan, their use is documented as far south as the old Hida Province, where they were known as .
A warada is a flat ring of plaited straw with a diameter of roughly . A wooden handle passes through the ring lengthwise and protrudes several centimetres from the edge. In some versions, the outer edge of the ring was lined with angled hawk feathers. Using the handle for leverage, a warada is thrown like a frisbee. In flight the spinning disc acts as an aerophone, producing a rhythmic humming sound very similar to the wingbeats of the predatory Eurasian goshawk. This sound, combined with the swiftly-moving shadow of the flying warada, frightens rabbits and will invariably cause them to burrow into the snow to hide. The warada hunter, having been watching from a distance, can then walk to the hole and pull the rabbit out with his bare hands before it has time to dig into the ground beneath.
The matagi, who lived in the forest alongside animals for centuries, had a deep understanding of ethology and were able to use this knowledge to develop advanced hunting techniques.
