Double Wakizashi Against Katana – Kenjutsu Sparring Experiment

Historically, dual‑wielding two Wakizashi was not a common or standard practice in Kenjutsu, as the Wakizashi was intended to be used in the off-hand alongside a full-sized Katana. However, dual-wielding two Wakizashi has appeared in recent fiction. For example, Shinomori Aoshi, a character from the manga and anime series Rurouni Kenshin, is shown using two Wakizashi simultaneously.

In this video, the two practitioners experiment with dual-wielding two Wakizashi against a Katana in a Kenjutsu context (not Kendō).
Due to its longer reach, the Katana provides an advantage for striking the opponent, but the Wakizashi dual-wielder is still able to land cuts by parrying with one weapon while attacking with the other.
From this demonstration, it appears that dual-wielding Wakizashi can be effective, though in practice, pairing a Katana and a Wakizashi would likely be a more practical and efficient combination.
