Aikido is a traditional Japanese Budo (martial art). As such there are clearly defined roles which regulate how each and every member of the dojo practices together. Since Aikido always involves practice with another person, one of the most important roles is that of SENPAI and KOHAI. Put simply, SENPAI is the senior student, and KOHAI the junior student. This role is irrespective of age. When two persons work out together, the SENPAI is the student who is of higher rank. In some cases, there is only a small difference between the rank of two persons. In such a case, both persons are on the same level and should respect each other as equals.

It is the duty of the senpai to teach the kohai. The extent to which the senpai does this changes in every case. Ultimately, the senpai should wish to only practice the demonstrated waza (technique) without pausing to be instructional. However, there are times when it is acceptable for sempai to give such instruction. It is the senpai ’s responsibility to provide the best level of practice possible to facilitate the kohai’s learning. This is an extremely important responsibility and one that the senpai must take VERY SERIOUSLY. This extends to a responsibility for all students of Aikido to teach what they have learned. Inherently, to teach what you have learned requires a significant time learning it yourself.

Aikido is a dynamic martial art. It is exceedingly easy to accidentally injure another person. It is the responsibility of all Aikidoka (people practicing Aikido) to protect their partners and not injure them or allow them to be injured. This rule is especially important for senpai , but it is true for kohai too. When one person is injured, the dojo as a whole suffers. This should be foremost in your mind while practicing.

THE DOJO

The DOJO is the "place of the Way". It is a sacred place. To do anything to defile the honored nature of the dojo is strictly forbidden. Shoes will not be worn on the dojo floor. The dojo floor will always be clean. You will bow to enter and leave the dojo. Such are the simple rules. But far beyond these ideas, the dojo is a place where people’s lives are changed and enriched. And as such it must be treated with respect. First and foremost is the interaction between persons on the dojo floor. Senpai and kohai must act in accordance with their prescribed roles. Any lack of respect or infighting is grossly disrespectful of the spirit of the dojo.

Aikido is a martial art that involves getting in close physical contact with another person or persons. When on the dojo floor, Aikidoka will wear clean training wear. Preferably this will be a dogi. Your appearance on the dojo floor reflects your attitude toward the place of the Way. Act accordingly.
