Yakumaru Jigen-ryū

The great-sword of Satsuma

Yakumaru Jigen-ryū (薬丸自顕流) is a school of Japanese swordsmanship from the Satsuma domain, in what is now Kagoshima Prefecture in Japan. Its formal name is Nodachi Jigen-ryū, the "great-sword" Jigen-ryū, and it was developed by Yakumaru Kenchin, a Satsuma retainer who, after mastering the Jigen-ryū of the Tōgō house, reworked his own family's long-sword techniques into a distinct tradition. Because the two schools share a reading and the same Satsuma homeland, they are often confused, but they are separate lines.

A sword of the single strike

Like the parent Jigen-ryū, the Yakumaru school stakes everything on a ferocious first blow. Its training is dominated by tategi-uchi, the repeated striking of an upright wooden post from a high stance, accompanied by a sustained battle-shout. The method spread widely among the lower samurai of Satsuma and became closely associated with the swordsmen of the domain in the turbulent final years of the shogunate.

Everything staked on the first blow, trained until it is the only blow needed.

A living Kagoshima tradition

Yakumaru Jigen-ryū is preserved today in Kagoshima, where it continues to be practised as a classical koryū with its characteristic posture, descending cut and shout. It remains one of the martial traditions most closely identified with the old Satsuma domain.
