School bands in the United Kingdom are generally similar to those in the US although pure brass bands are more commonplace in schools than in the US. Some countries usually prefer certain special types of bands, usually drums, over conventional ones. The school band movement in Japan is unusually strong, organized around an enormous competition system administered by the All-Japan Band Association. Many international observers of Japanese school bands consider them to be the most impressive in the world, particularly among very young students, and Japan is also home to one of the world's leading professional concert bands, the Tokyo Kosei Wind Orchestra.
