Kūsankū (kata)
open hand karate kata

Kūsankū (クーサンクー) is a kata of karate and is practiced mainly in the Shuri-te lineage. It is also called Kūshankū (クーシャンクー), Kōshōkun (公相君) or Kankū (観空).
Variations of Kūsankū include Dai and Shō, which have been known since the early 20th century, but today differ from school-to-school. Additionally variations exist, such as Chatan Yara Kūshankū. There is a theory that Kūsankū originated with Kōshōkun (Okinawan dialect: Kūsankū), who visited Okinawa during the Ryukyu Kingdom in the mid-18th century, but no primary historical evidence has been found to substantiate this theory.
In Shotokan, the kata has been known as Kankū (観空, lit. 'gazing at the sky') ever since it was renamed in 1935 by Funakoshi Gichin. This kata is also practiced in Tang Soo Do as Kong Sang Koon (공상군) in Korean according to the hangul rendering of the hanja 公相君. Most schools of Tang Soo Do only practice the "Dai" version but a handful do practice both the latter and "Shō" versions.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Kūsankū (kata)”, the useful work is to connect “open hand karate kata” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 30, 2026. The linked authority identifier is Q3200651. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1935.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account.
