What is the difference between an odachi and a nodachi?
Updated Feb 2026
The terms odachi and nodachi are often used interchangeably, and both refer to oversized Japanese swords. Technically, odachi (大太刀) translates to "great sword" and is the more general term, while nodachi (野太刀) translates to "field sword" and specifically references battlefield use. In modern collecting, both terms describe the same category of extra-long Japanese swords with blades exceeding standard katana dimensions.
