Here is a list of newly listed Martial Arts Schools, Clubs & Dojos on dojos.co.uk. Only the latest 50 Dojos are shown here. A new Dojo listing does not always mean that the Dojo is actually new, it may have been operating for several years.
There is also a list of recently updated schools.
You can subscribe to Dojo Loator's Twitter Feed @dojolocator to stay informed of newly listed Dojo and Dojo Updates. Another option is to subscribe to the RSS Feed of new Dojo listings.
