Judo Station is held in the School's own dojo, on the second floor of the Sports Centre. About 15 pupils receive instruction from an expert (former Olympian) external coach, and members of teaching staff also supervise. There are occasional fixtures with other schools, culminating in the Independent Schools’ Championships, where Westminster has enjoyed notable success in recent years.

The Judo Club aims to develop pupils’ throwing, locking and grappling skills and their physical fitness and general health. Equally, it is the aim of the Station to develop pupils’ mental abilities; since concentration, focus and intellectual understanding form an integral part of the sport. Within this, pupils are encouraged to develop confidence and maturity, a calm and reasoned attitude and the fostering of compassion and peacefulness. They are encouraged to be honest, kind and courteous and to have respect for the traditional etiquette and discipline of judo.
