History
The name ZYX is a kind of acronym using a somewhat intricate play in notation. "Z" and "Y" are taken from the phrase Zettai Yume o Bai ni "Bai ni," meaning "double in size," is represented not as "B" but as a multiplication sign "×" which was then represented by the letter "X." Also, the letters ZYX are the last letters of the English alphabet in reverse order. In Hello! Project, this inverted order naming is followed by the groups "W" created in 2004, "v-u-den" in 2005, "The Possible" in 2006, and SI☆NA in 2008. This line-up of groups continues the reverse alphabetical naming.On February 28 and March 1, 2015, ZYX reformed for Berryz Kobo Matsuri with Momoko Tsuguana, Saki Shimizu and Maimi Yajima to perform "Shiroi Tokyo", the first time members of the original ZYX line-up have reformed under the name ZYX since 2006.
