Lit. dovetail tenon. Also *arikake 蟻掛. A tenon shaped like a dove's tail with each side cut obliquely so that it is wider at the outer end than at the inner. When the tenon is inserted into the mortise from the top, it is sometimes called otoshiari 落蟻 or *ariotoshi 蟻落. Arihozo is used for either a splicing or a right angle joint.
