Jinpachi Munashi (無梨甚八, Munashi Jinpachi) was a former member of the Seven Ninja Swordsmen of the Mist of Kirigakure.

Utilising the unique "explosion" sword Shibuki, Jinpachi intuitively combined expert swordsmanship with destructive explosions, due to the significant quantity of explosive tags incorporated into the platform-like edge. Once these tags detonate an integrated scroll deposits another set along the same edge, allowing the sword to be used consecutively. However, the capabilities of this weapon do not come without risk, as the user themselves can potentially be caught in the resultant blast but Jinpachi's skill is such that this does not occur.
