Tento Uchi 天頭打ち is an uncommon term used in koryu styles to mean a strike to the top of the head. A downward strike targeting the very top of the opponent’s head (the crown), which is a structurally vulnerable point and is often attacked from Jōdan no Kamae (high stance). In Kendo, this strike is similar to a Men Uchi (面打ち) to the head. In koryū styles, it’s often taught early as Makkō Giri (真向斬り) or Shōmen Uchi (正面打ち).
Translation
