The Seventh Samurai

Had a little explore around Guys hospital. There's a historic courtyard that I hadn't seen before. 

A group of Japanese were gathering with long cloth cases containing what? After a few minutes two of the group started doing samurai type moves with the concealed items. So I presume they were some kind of ceremonial sword. But that wouldn't be allowed, so the mystery continues.

One of the group was evidently exhausted so took a break on the steps. Perhaps they were sleeping off the night before.
