Judo Itsutsu no Kata

Itsutsu-no-kata (五の形, "forms of five")

This summary is mostly from online sources.

is a kata (a set of prearranged techniques) in Judo. It consists of five techniques, known only by their number. Although popular media generally claim that it was developed by Jigoro Kano, recent scientific research has conclusively shown that the kata predates the foundation of Kodokan judo and that Jigoro Kano took it from Tenjin Shinyō-ryū jujutsu and merely imported it into judo after he made minor amendments to it. The kata is considered unfinished. However, a completed performance version of the kata, expanded to ten techniques, was recently presented under the name Tō-no-kata (十の形, "forms of ten"). The techniques of Itsutsu-no-kata are composed of gentle movements evocative of natural forces.

Techniques

• Ichi - direct concentrated energy - direct push

• Ni - deflection - avoid and use Uki otoshi

• San - circular energy or whirlpool - using form of Yoko wakare

• Shi - action and reaction - as the sea sweeps clean the shore

• Go - the void - using form of Yoko waker

Spear (Yari) in Owari Kan Ryu 尾張貫流 (Kudayari & others)

Owari Kan ryū is known for its use of the kuda-yari (tube spear). The e (shaft) is run through a kuda (metal pipe) that’s in the front hand of the practitioner. Interestingly the school’s students start training by doing shiai (competition) and only after considerable training they learn the school's kata (forms). Most classical schools that practice shiai do so after learning kata. Thrusting using the kuda. Cross-stepping. Thrusting attack with kuda. Wide stance. Shiai. Shiai using a spear with a cross piece.

The Structure of the Tenshinshoden Katori Shinto Ryu Syllabus

It should be noted that the current head, Otake Risuke, has commented that not all of the parts of Tenshinsho-den Katori Shinto Ryu survive. I recall his comments in various documentaries that Archery was once a component, and only some of the spear survives. Through various sources, mostly Otake's book, I have put together this brief outline of their syllabus, however I have little idea of the exact stage each is taught except that I believe the students start with Omote no Tachi. I will use this as the basis for further posts and may add to it over time. I believe their are important implications when Otake says that one of the main reasons for training all the weapons is to train the swordsman against them. Note in this section in brackets are my own comments and should therefore not be relied upon, those from the written work of Otake are clearly marked.

Australia’s Turning Point – Signals Intelligence leading to the Battle of the Coral Sea

Australian/American Signals cooperation was not only important in stopping the Japanese advance to Australian shores but marked the beginning of Australia embedding its forces with the United States rather than simply furnishing troops for the British. Whilst the British, in my opinion , had a long history of using Commonwealth troops to either protect their colonial interests or to take on deployments with high expected rates of attrition, when Australia faced the real possibility of invasion with the vast majority of its troops and equipment deployed overseas, it was the Americans, whose interests in the Pacific aligned with our own, that were on hand to push the Japanese back from our shores. The Battle of the Coral Sea saw the beginnings of the deployment of Australian sea power under direct American command, a joint approach that would continue to the present time – it was, however, Signals Intelligence that led the way to the embedding of US/Australian forces and played a major
