Your ken, jo, and tanto, should be in good condition, and in their appropriate place when not in use. Your body and, in particular, your feet, must be very clean before you step onto the mat. Keep your nails short to avoid injuring yourself or others. If you think you know already, it will be difficult for you to learn. Please, do not play on the mat.
Most injuries are the consequence of playing.
Please do not come to train when you have ingested any type of drug or alcohol unless it has been prescribed for your health. There is no place for negativity in the training hall. No rings, watches, or jewelry of any kind should be worn during practice. These items can injure yourself and others. If you are ill or over-tired, do not attempt to train in the dojo.
