A noachi (野太刀:のだち, nodachi?) is a large two-handed Japanese sword. Nodachi approximately translates to "field sword". However, some have suggested that the meaning of "nodachi" is roughly the same as ōdachi meaning "large/great sword". A confusion between the terms has nearly synonymized "nodachi" with the very large "ōdachi". Thus, while the original use of the term may have been to refer to any type of long battlefield sword (daitō), including the tachi, it is frequently misapplied to any type of oversized Japanese sword.
