I went to a festival this past Saturday, held downtown. There were people dancing on a stage, people playing music, and a lot of people selling food.
Here’s a video of some of the vendors and things for sale at the festival. You should be able to hear people shouting “Irasshaimasse~~!!!” which roughly translated means “Welcome to my shop!” but in this case, it’s more like, “Look at me, I’m selling stuff!”
