"The use of the terms Tomiki-ryu, Tomiki System, etc. prompted an austere look and resolute manner, “It was never my aim to create competitive aikido for only one specific group”. I can recall his politeness and the things he used to say about his cherished ideas. So why was Tomiki Sensei so strongly against having his name used? I think that this was because he had much more sincere and more noble ideas concerning aikido and budo. At that time he mentioned the name of Kano Shihan to use as an example, “Kano Sensei aimed at creating judo as a modernization of budo. Although he established judo, we never hear term Kano Judo.” Referring to own’s name in this way is shortsighted and won’t allow budo to change at all. Tomiki Sensei did not boast about competitive aikido belonging to him but believed it was connected to the development of aikido as a whole and for the benefit of everyone. He believed strongly that without this process aikido would not modernize. This way of thinking was perhaps why he was particular about the name."
"The meaning of Shodokan is 'place for identifying the way'. The first character, 'sho' comes from the Showa period in which Shodokan was founded and is also found in the name of Uchiyama's company. The second character, 'do' comes from Kano's Kodokan. (clip) On 28th March 1976, Uchiyama provided a 70 tatami dojo with Tomiki as the head."
"Through peripheral and ambient vision, the brain senses the body's movement, orientation in space and relationship to objects in the environment. Vision also detects the stability of a surface or object. For example, seeing a swaying rope bridge causes a different response in the body than seeing a sturdy pillared one. When the eyes focus on a steady object, the vestibular system of the inner ear can orient the head vertically, horizontally and spatially. This helps stabilize the body."
"The vestibular system, which contributes to balance in most mammals and to the sense of spatial orientation, is the sensory system that provides the leading contribution about movement and sense of balance. Together with the cochlea, a part of the auditory system, it constitutes the labyrinth of the inner ear in most mammals, situated in the vestibulum in the inner ear (Figure 1). As our movements consist of rotations and translations, the vestibular system comprises two components: the semicircular canal system, which indicate rotational movements; and the otoliths, which indicate linear accelerations. The vestibular system sends signals primarily to the neural structures that control our eye movements, and to the muscles that keep us upright . The projections to the former provide the anatomical basis of the vestibulo-ocular reflex, which is required for clear vision; and the projections to the muscles that control our posture are necessary to keep us upright."
"To stand, walk, or climb without falling, we must maintain our center of mass over and within a base area. When someone is standing erect, the base can be considered the normal footprint. The shape, size, and position of the base changes depending on the pattern of movement and the activity. When walking, we constantly readjust our body segments over our base to maintain stability. The brain, vision, body condition, and the nature of the contact with the surface all contribute to the sensitive balance required to maintain walking stability. If a foot slips or is mispositioned, the center of gravity shifts outside the base area. When this happens, we shift our body parts in an attempt to regain equilibrium. If the center of mass cannot be shifted back over the base area, we fall."
