From Tadashi's website.
A Japanese Sword Dance will be one of many performances in downtown Pittsburgh on New Years' Eve as part of First Night Pittsburgh. The performer, Tadashi Kato, will present "a sword dance based on the mixture of traditional Japanese martial arts and American modern dance." A fuller profile on Tadashi is available at his website. He most recently performed in Pittsburgh at Kennywood's Asian Day last May.
There are two free performances scheduled at Pittsburgh CAPA School: 6:45 to 7:00 pm, and 9:00 to 9:15 pm. The school is located at 111 9th St. (map) in the Cultural District.
