Tameshiwari (Breaking) Rules
- All competitors are required to have submitted a description of their intended break (using text and/or diagrams) prior to the Tournament. At the discretion of Tournament Officials, a late-entrant may be permitted to compete, but must submit such a description prior to the start of competition.
- Tournament Officials have the unlimited right to disqualify a proposed break for any reason. In the event that a break is disqualified, the Competitor may submit a revised break plan; however, Tournament Officials may decide that a competitor may not resubmit a plan, and disqualify him or her from competition.
- No design shall use or propose an action that may put fellow competitors or spectators at risk.
- No design shall employ the use of combustible or explosive materials.
- If the design proposes the use of boards, only the standard board size of 1x11x12 (dimensional inches) for Adult competitors and 3/4x11x12 for Kids competitors is permitted. Boards shall be made of pine wood, and substantially free of defect, and may not have been treated with foreign substances or the application of extreme heat or cold to weaken their structural integrity.
- A competitor may propose a break that has up to three individual separate breaks, although only one break is required.
- If spacers are used, they must not be greater in actual size than 0.75 inches in either height or width, and no longer than 0.5 inches than the maximum length of the material they are separating.
- No material may be taped together, or otherwise held together, except by being held by an assistant during a break.
- No material that is involved in a break may be padded or taped, nor may a cover be placed over material to lessen impact or contact damage to the competitor.
- Tournament Officials will set the minimum rank levels for competitors. In Goju Karate Tournaments, Adults must be at least 4th Kyu in rank; Teens must be at least 2nd Kyu in Rank; and all other competitors must be 1st Kyu in rank and be at least 10 years of age.
- No competitor may wear any covering, including tape of any kind, on any striking surface used in any proposed break. In addition, no tape, bandage, or other method of external support is allowed on any joint (ankle, wrist, knee, hip) adjacent to a breaking surface.
- All competitors must conform to the standard uniform required at Tournament. For Goju Karate Tournaments, this includes a full Gi, with appropriate Goju Karate insignia.
- At all times, Competitors will conduct themselves in the full spirit of karatedo; failure to do so is grounds for immediate disqualification by the Chief Judge and any other senior Tournament Official.
- Scoring is divided into three components: success of break (maximum 18 points), creativity of break (maximum of 6 points), and difficulty of break (maximum of 6 points).
- Success of break is computed as follows: (a) if there is only one break, and if its successful, 18 points are awarded; if unsuccessful, no points are awarded; (b) if there are two breaks, and only one break is successful, 9 points are awarded; if both breaks are successful, 18 points are awarded; if no break is successful, no points are awarded; (c) if there are three breaks, 6 points for each successful break is awarded, to a maximum of 18; if no breaks are successful, no points are awarded.
- Creativity scores are computed as follows: up to 3 points are awarded based on how creative the break design and setup is; up to 3 points are awarded based on how “appropriate to demonstrate technique” the break design is. Keep in mind that the point of tameshawari is to demonstrate good technique and strong spirit, and the break must be designed to do that.
- Difficulty scores are computed as follows: up to 3 points are awarded based on difficulty of materials used; up to 3 points are awarded based on the action and weapon of the break.
- If there are more than three judges, then the highest and lowest score shall be dropped, and the remaining scores averaged, and the average shall be computed to the tenth’s decimal place, with rounding. If there are three or fewer judges, all scores are averaged and computed and rounded as described here.
- Breaking shall occur in the event space as designated by Tournament Officials. Prior to breaking, competitors shall have a minimum of fifteen minutes to setup their breaks. At the end of the time allotted, competitors shall stand in their area and await instructions from the Chief Judge.
- Only competitors are allowed in the competition area. All competitors are permitted one assistant to setup, even if the assistant is not holding material during a break. However, any assistants not part of the break (for holding) must leave the competition area once the fifteen minute setup period is over.
- At the start of competition, the Chief Judge shall instruct competitors as to whether they will break simultaneously, or in smaller groups, or individually.
- The judges shall examine the break setup, and compute initial scoring for creativity and difficulty.
- The Chief Judge shall instruct the timekeeper to prepare the start signal.
- The start signal shall sound. Competitors have 120 seconds from the start signal to begin their break and complete it. In the event the competitor does not make contact with a breaking target surface within that 30 seconds, he or she shall be disqualified.
- Once the 120 second time period has elapsed, the finish signal shall sound. Once the signal has sounded, competitor(s) must sit seiza and await final scoring based on break success. Failure to do so shall result in a success score of zero.
- These rules may be revised at any time at the sole discretion of Tournament Officials, and shall be immediately in-force.
- No appeal regarding a score is permitted under any circumstance or for any reason. No appeal regarding rules or rule enformcentn under these rules is permitted other than appeal to the Tournament Director. Any decision by the Tournament Director, including the decision to reject an appeal outright is final.
