Kusanku (Scroll Down to Sai Kata Below)
     Often described in Isshinryu as a “night fighting kata,” this form was passed down from Kyan Chotoku to Shimabuku Tatsuo.  Interestingly enough, no references to night fighting are found in the primary references coming out of Japan and Okinawa, leading one to believe that such interpretations were contrived to fit the movements that are not very well understood.  Another explanation is that Shimabuku Sensei saw the adaptive nature of this kata to night fighting and taught his students to practice it “as if in a dark place” (Advincula, 2002).
     In the year 1762, a tribute ship sent to Satsuma from Ryukyu was blown off course during a storm, and ended up landing at Tosa Province in Shikoku Okinawa, where they remained for a month.  The Confucian scholar of Tosa, Tobe Ryoen (1713-1795), was petitioned to collect testimony from the crew.  The record of this testimony is known as the Oshima Hikki (literally “Note of Oshima”, the name of the area of Tosa where the ship had run aground).  In this book, there is some very provocative testimony by a certain Shionja Peichin, describing a man from China call Koshankin, who demon-strated a grappling technique (McCarthy, 1995; Sakagami, 1978).
     It is commonly accepted that this Koshankin was the originator of the Okinawan Kusanku kata, or at least inspired it.  However, there are several unknowns in this equa-tion.  First of all, was Koshankin his name or a title, or even a term of affection towards him?  Second, if it was a title or term of affection, what was his real name?  Thirdly, what martial art(s) did he teach anyway, and how did they differ from the modern karate kata especially the Kusanku kata as Shimabuku Sensei taught it?
     For now, suffice it to say that Kusanku is a highly important kata in the Okinawan martial arts, and has spawned many versions over the years.  Some of them include the Kusanku Dai/Sho Itosu Anko lineage styles, the Chibana no Kusanku of Shodokan, the Takemura no Kusanku of Bugeikan and Genseiryu, the Kanku Dai/Sho of Shotokai, the Shiho Kusanku of Shitoryu, and the Yara no Kusanku of Kyan Chotoku lineage styles, including Isshinryu.  Of course, there are numerous others as well.
     Kyan Chotoku is said to have learned Kusanku in Yomitan Okinawa under a cer-tain Yara Peichin (Nagamine, 1975; 1976).  It is unknown at this time whether there is a familial relationship between this Yara Peichin and the Chantan Yara who is believed to have studied under Koshinkin during his mid-18th century visit to Okinawa.  Chantan Yara is the Sensei who created or for who was named the third Sai kata (Chantan Yara no Sai) for Nidan rank, the others being Kani Sai, and Kusanku Sai.  Koshankin was the predecessor of the Kyokushinkai system of Japan of which Oyama Matsutatsuo Soge was the founder.
