Along my walk from Harajuku to Shibuya I passed through a complex that included the NHK broadcasting facilities and a large open area that would probably be called a county fairground in the US. There was an event going on that day with lion dancers on a small stage area, and drummers like the one in the photo all around the area. Of course, there were also the numerous food and beverage stalls that one would expect from any outdoor event like this, anywhere in the world, and plenty of people walking around watching.
thanks for information
