Koshirae () is the Japanese term for a complete set of mounts of edged weapons. This includes the complete set of hilt, guard, and scabbard of the Japanese swords tachikatana, wakizashi, and the daggers called tanto. But also the pole, guard, and scabbard of polearms like the yari, naginata, etc.

What sets koshirae apart from sets of mountings of weapons in other cultures is that they are so easily interchangeable; usually, it only requires the removal of a single pin to be able to swap the entire hilt of a sword. Therefore it was common to have more sets of koshirae for a single blade. Wealthy samurai were said to have more sets of koshirae per blade than there were days in a year.

"Sword mountings played an important part in the training of the Japanese of the highest classes. They formed a part of his daily life, they were frequently changed, and wealthy men are said to have had sufficient "stock" in reserve to allow favorite swords to appear in different dress each day in the year." 1

-Bashford Dean, 1921


Because of the temporary nature of the mounts to the sword, the Japanese sword connoisseurship generally only occupies itself with the sword blade. The study and appreciation of mounts are considered a different field entirely. It can be compared to the frames of master paintings; one doesn't judge a Rembrandt by its frame. One can have an opinion on how the frame matches the painting, but one will never see the frame as integral to the painting.

Due to people changing the koshirae of their weapons regularly and keeping up with the latest fashions and regulations, it is very rare to find early sets of koshirae.
