It was said that the Kurume P.O.W. (prisoners of war) Camp was the worst camp of the P.O.W. Camps in Japan during the First World War, because the Camp was imperfectly equipped and the Camp Authority treatred German war-prisoners harshly. The purpose of this paper was to clarify Turnen and sports activities of German war-prisoners in the Kurume P.O.W. Camp. The historical materials used for this paper were collected mainly from the newspaper "Turnen und Sport" which was written and published by the German war-prisoners in the Kurume P. O. W. Camp. The findings of this study were summarized as follows: The Kurume P. O. W. Camp had two playgrounds (a big ground and a center ground) and a track at the corner of the Camp. In adittion, there was one tennis court and one Faustball-field for officers, and one mini-tennis court for lower ranked officers. German prisoners organized various clubs and they were very keen on Turnen and sports activities such as gymnastics, football, tennis, hockey, Schlagball, Faustball, boxing and wrestling. These activities Were very important for the health of body and mind of German prisoners. The fact that German war-prisoners practiced these sports and Turnen diligently under the severe circumstances of camp life, in the dawn of sport in Japan, should not be neglected in considering the history of sport in Japan.
