The sword is in its original koshirae. The fittings consist of a falling rain copper habaki, very nice floral fuchi-kashira done in gold and shakudo, and a peony flower design suba. The fittings were made by someone at the top of their game.

The urushi is largely in good condition, with some minor damage towards the kojiri, but this is easily professionally repaired. The tsuka can also easily be rebound.


This is a beast of a sword and probably Yamato school. Swords of this length are uncommon and highly sought after.
