They have to watch what is going on and prevent anything potentially dangerous. You must therefore follow their directions promptly and take heed of their advice. If you feel ill or are injured tell the instructor, similarly if you need to leave the mat for any reason you should inform the instructor. The majority of the club's income goes towards the upkeep and refurbishment of the premises, payment of instructors and managerial staff and on other typical expenses that any homeowner has electricity, heating, telephone, water, rates. Some money is also used to support players when they represent the Budokwai in competitions or when they represent Great Britain at international events.
Any surplus money is ploughed back into the club.
The Dojo is regarded under Eastern philosophy as embodying the spirit of the sport, rather than simply as a training hail. In keeping with this philosophy we bow when entering and leaving the Dojo. In a similar way, we show respect by a formal bow to the instructor at the commencement and end of a class, and to one's partner at the start and finish of a randori or contest. Respect to the Dojo and to your fellow members is also demonstrated by cleanliness and personal hygiene. This is important in all martial arts but particularly judo as it involves close bodily contact.
