“The Unknown Dancer in the Neighborhood,” part of Japan Society’s 2019-2020 Performing Arts Season and The Public Theater’s Under the Radar Festival, is written & directed by one of Japan’s most acclaimed rising young playwright-directors, Suguru Yamamoto, and performed by dancer/choreographer Wataru Kitao. This contemporary dance theater piece features Yamamoto’s signature directing style, in which characters’ thoughts are conveyed through projected words, alluding to the millennial generation’s preferred mode of communication — texting. Blending movement, photography and colorful lighting, Yamamoto reveals the indifference and tenderness of a metropolis where the lives of complete strangers continuously interact and coalesce.
