The Yukiwa are reinforcements of the Kotegashira on places under important constraint, especially friction.

It is an effective alternative to full Clarino or Deerskin Kotegashira, when looking for an easy to dry or light Kote while keeping it sturdy.

Yukiwa types :

• Tsubazure : Yukiwa around the inside of the index and the thumb. On the right hand, it reinforces the Kotegashira against the friction caused by the Tsuba. On the left hand, it reinforces the Kotegashira against the friction caused by the Tsukagawa.
• Yako : Yukiwa wich cover the thumb, index and middle finger, as well as part of the hand, for an extended reinforce zone.z
• Tsumekawa : Additional Yukiwa at different place around the Kotegashira to reinforce specific zone.
