Yagyu Shinkage Ryu Juji 柳生新陰流手裏剣
Yagyu Shinkage Ryu 柳生新陰流 Juji Shuriken are possibly one of the best varieties of Hira Shuriken, The long rounded needle sharp points and thick overall construction of the Shuriken give them excellent penetration on the target.
Yagyu Shinkage Ryu is one of the oldest schools of Kenjutsu, It’s primary founder was Kamizumi Nobutsuna who called the school Shinkage Ryu (New Shadow School).
In 1565 Kamizumi Nobutsuna handed Sokeship of the school to Yagyu Munetoshi who added his own name to the school.
It has been believed for centuries that the Yagyu Shinkage Ryu School of swordsmanship also studied Ninjutsu skills and tactics, mainly during the time of Yagyu Munenori, Yagyu Munetoshi’s son.
The specifications for the Yagyu Shinkage Ryu Juji are as follows:
Length: 11.5cm point to point
Width: 1.2cm at base

As Hira Shuriken the Yagyu Shinkage Ryu Juji are probably the best, their are some minor pitfalls such as the denser construction makes them less aerodynamic than Koga Ryu Juji but its a trade off between increased penetration and accuracy at a distance.
