Page "Kyūdō" Paragraph 37

The one-finger glove, called an ippongake is generally used for beginners and covers only the thumb.

Some versions have a full wrist covering and others simply cover the thumb with a small strap and snap around the wrist.

Because it has no glove over the fingers, it is typically uncomfortable for the archer to use giriko powder.

Ippongake are generally not used by advanced archers, and cannot be used in Kyudo Federation competitions.
