Kashima-Shinryu (鹿島神流) is a traditional Japanese school of martial art (koryu bujutsu), tracing its roots back to the fencing techniques of Kashima-no-Tachi. Following a curriculum dating back to the 16th century, practitioners of Kashima-Shinryu study a variety of combat disciplines, including the sword (kenjutsu), grappling (jujutsu), the halberd (naginatajutsu), the spear (sojutsu), the knife (kaikenjutsu), and short and long staff (jojutsu and bojutsu). Based on traditional teaching techniques, Kashima-Shinryu does not include any modern sportive elements such as group drills, sparring, or tournaments. Instruction instead relies on paired teacher-student exercises and is provided only on a non-commercial basis with the explicit authorisation of the current headmaster (shihanke).
