Nagesen is a traditional way in Japan for supporting street performers. The life of a street performer is not so easy. They need a great performance plus having ability and charm of getting sympathy from audience. If they don't have this ability, they can not get any coins. There is no entrance fee like a theater.
Audience sometimes stop to see a performance on street or park.
If a performer gives great pleasure to the audience, they will loosen their purse. The audiences thinks that the performer should live long and continue to perform, our life will be more fun. Sometimes they become a great patron, and they might treat the performer to a great dinner. We put hats for patron-ship in front of websites. We don't have any way of getting small charge from web audiences.
