Also called inrōtsugi 印籠継. A simple blind or half-blind stub tenon joint. A blind tenon, mechigaihozo 目違ほぞ, is formed by cutting away the sides of a timber to produce a projecting vertical rectangle which fits into a blind or stub mortise. The mortise is called mechigaiire 目違入 or inrōire 印籠入. On occasion more than one blind tenon is used and an equal number of blind mortises are carved into the opposite timber. If the blind tenon and mortise need further strengthening, holes can be bored in the tenon and mortise and a pin *sen 栓 inserted to secure them. The shape of the blind tenon and mortise may vary. The most common variations are the blind, squared-shape, hako mechigaitsugi 箱目違継 and the L- or reversed L-shape, kaneori mechigaitsugi 矩折目違継. These basic types of joinery are used widely in combination with other joints; koshikake mechigaitsugi 腰掛目違継, mechigai koshikake aritsugi 目違腰掛蟻継, *nogetsugi 芒継.
