Once a year the Japanese Gardens in Rockford, Illinois hosts a Japanese Summer Festival with a heavy focus on traditional culture. With suits of samurai armor to try on, hand on origami work shops for kids, taiko, and even obon odori this event is an amazing sampler! Admission is generally under $10, and free to members of the gardens.
