Presentation of clubs to shin ichi nen sei - 15.jpg
Originally uploaded by Jason In Japan.
during the first weeks of the new school year, all the clubs in the school have kind of an open-house, where the new 7th graders can stop by and watch them practice and see which after-school club/sports team they want to join. Before that they have an assembly in the gym where all the clubs give a short presentation extolling the virtures of their club, how often they practice, what tournaments they have coming up, etc.
Then they usually give a little demonstration - judo throws, volleyball spikes, tennis lobs, chorus singing, etc.
I uploaded some pics from this assembly and I have some video from that day too which I'll try to post to my YouTube site soon.
