Marewrew is an all female singing group dedicated to reviving, promoting and preserving the traditional Ainu musical form of “upopo.” Slightly similar to Western canons, an upopo song traditionally consists of various rhythmic patterns sung by 3-4 female singers at different timing, creating an organic, trance-like experience for the listeners. The current four members, Rekpo, Hisae, Mayunkiki and Rim Rim, solidified the artistic direction and vision in 2007, and have been garnering high praises from the audience, critics and musicians in Japan and beyond. With the acclaimed tonkori player and Ainu music producer OKI, Marewrew has toured extensively in Japan and in countries such as Taiwan, Australia, Germany and the United States of America. In 2010, Marewrew released a self-titled debut album produced by OKI’s Chikar Studio and launched a series of events titled “Marewrew Festival – 1,000,000 Voices; One Upopo Challenge,” a combination of live concert and audience participation. Most recently the festival was held at Asahi Art Square in Tokyo on September 1, 2012. Their 3rd album, “Motto ite, Hissori ne”, was released in August 2012.
