At about an hour in, there is talk about how one of the characters has a club, because who will arrest you for having a club? A sword, yes, but a club?
One of the instruments I had the opportunity to play in college was the shakuhachi
, a bamboo flute about 55 centimeters in length. It was exclusively played by monks who were allowed to travel around feudal Japan. These monks were given the right to travel the countryside as their sect had a strong tradition of pilgrimage. Some of the monks, however, were spies for the shogunate, and others were ronin who pretended to be monks for various reasons.
And of course, carrying a weapon or sword was forbidden to most, but this, oh, this is but a simple bamboo flute! Never mind that it is almost 2 feet in length and I could club you with it…
