The Yagyu Koshirae is an High End Iaito fully order-made in Japan, made with a sandcasted bubble-free zinc/aluminum alloy blade. This model has a "standard" blade for an average weight that results in a classic Iaito balance centered toward the Tsuba, and should be suitable for all practitioners. It is an excellent iaito for beginners and intermediate alike who have enough budget to acquire a weapon of higher quality that allows some customization.

Minosaka's Iaito lineup allows many customisations but each model is fixed and named depending on its Fuchi & Kashira, for this model, the Yagyu Kasumi Fuchi/Kashira set.
In Japanese, Kasumi means "Mist" or "Haze". Consistent with the Inro lacquer of the Saya, this "mist" theme reminds us of the famous Yagyu Shinkage Ryu Kenjutsu school created by the Yagyu family. Shinkage meaning "the new shadow", the symbolic is consistent with this mist themed Yagyu Koshirae Iaito, which is actually a reinterpretation of an antique sword of the Yagyu familly currently privately owned.

In addition to its original Fuchi/Kashira set, the Yagyu Koshira has two other specifities, its gorgeous Inro Saya and Sakasa (reversed) Menuki.
The large wave pattern of the Inro Saya goes all the way down to the Sayajiri and offers a much better grip on the Saya making it very practical on the battlefield. The Inro Saya is available as a Saya option without additional fees and only for this model.
The Menuki are usually placed up on the left (omote) side and down on the right (ura) side. Reverse position (also called Sakasa Menuki) will place the Menuki on your palms rather than under your fingers.
