A type of right angle, mitered, housed, and dovetail joint used mainly on flat timber as, for example, in the upper architrave of an alcove in a mansion, tsukeshoin 付書院. The front corner and top edge of this joint are mitered because a triangular space is created on the inner end of the dovetail groove, arimichi 蟻道. This joint is suitable for producing a clean line.
