Hibiya Park
On our first day in Tokyo, I wandered around the area while Tammi napped and came across Hibiya Park, just a couple blocks away. Shortly after getting into the park, I started to hear yelling and chanting coming from one corner. I followed it to discover these guys flailing about singing and gesturing to each other. I have no idea what it was.
On the way out, I found another set of guys doing the same thing, this time making stabbing motions towards themselves. It was very strange.
