For enthusiasts it is certainly an interesting and engaging experience. The Japanese instructor and staff are very nice and make the most of the class time. Obviously, in just one hour, at most an hour and a half, one only has the possibility of just skimming the surface of this ancient and fascinating Japanese art. But, as neophytes, what this experience has left us is a pleasant, instructive and intense moment of history and concrete action, lived in samurai clothes, holding, unsheathing and making the katana vibrate following the instructions (for us Europeans, in English ) of the master. We were six adults in the group and we all had fun trying out the two/three movement sequences or "choreographies" we had just learned. Please bring your cell phones/cameras with you, because the instructor will be your photographer! PS: Even if swords are NOT sharp they are still made of steel and must be handled with care.
