Umehara Masaru (梅原大), known by his pseudonym U.M.E.D.Y., was a Japanese rapper and notable figure in the underground hip-hop scene of Japan, who began working with Hello! Project in 1999. He is also a former producer of the hip-hop units EDU[1] and SPICY CHOCOLATE, and the former MC of the R&B unit Sin.

U.M.E.D.Y. passed away on December 21, 2017 from glioblastoma.[2]


Umehara Masaru was born on September 6, 1971 in Japan.[3] As a child, he mostly listened to Japanese pop music but became interested in rap music as a teenager after he listened to an album by the American hip-hop group RUN-DMC.

He graduated from Fukushima Prefectural Asaka High School in 1990 and the University of Tsukuba in 1993, where he majored in sports psychology. He was a member of the Koriyama International Swimming Club[4] and the editor of the magazine Monthly Swimming Life. It was during his college years that he met DJ Etsu and the two began throwing parties where they would perform together, which eventually led to the pair organizing their first live at a shopping center scouting talent such as Baby Setsu, Miss Monday and Yuka (later known as the group "NOW") to perform as supporting acts.

After their first live, Umehara and DJ Etsu formed the hip-hop group EDU, which also featured Umehara's brother Taka-C and the trio performed at small venues for little-to-no-pay. In December 1994, the group struck success when they won a televised hip-hop competition and signed an exclusive recording contract with Avion, a subsidairy of Victor Entertainment, and soon afterwards released their debut album which sold approximately 20,000 copies. However their success came at a price, as Taka-C disagreed with the mainstream direction of the group and left, which ultimately led to their disbandment. In the years following EDU's disbandment, Umehara remained active as both a rapper and music producer, and began working as a manager for Miss Monday.

He provided rap vocals, chorus vocals, and arranged rap lyrics for Hello! Project songs since 1999. He stopped working with Hello! Project in late 2000 after "Ren'ai Revolution 21" to focus on Miss Monday's career, but returned after ten years, beginning with "Odorou yo."[5]

U.M.E.D.Y. produced a total of 17 albums for SPICY CHOCOLATE,[3] and he received a 57th Annual Grammy Awards nomination for THE REGGAE POWER, their 2014 collaboration album with rappers SLY & ROBBIE.[6]

His wife, R&B singer Miss Monday, notified fans via Facebook that he had passed away on December 21, 2017 after battling glioblastoma since 2012.[2] They had been married since September 10, 2010[7] and welcomed a son on November 28, 2015.[8] Beginning with Choux Cream Rockets' 2018 song "Yonaka Douga Bakari Miteru", Miss Monday has been teaming up with Tsunku to arrange rap lyrics. In 2019, she arranged the rap lyrics for Morning Musume's song "Seishun Night", marking her first work with Hello! Project.
