Wikipedia explains "Judy and Mary was a Japanese multi-genre band known for their innovative punk, rock, and pop meldings of noisy but melodic music in the 1990s. They formed in 1991 when bassist Yoshihito Onda (恩田 快人, Onda Yoshihito?) met vocalist Yuki Isoya (磯谷 有希, Isoya Yūki?) in Hakodate, Hokkaidō. Much later, drummer Kohta Igarashi (五十嵐 公太, Igarashi Kōta?) and guitarist Takuya Asanuma (浅沼 拓也, Asanuma Takuya?) were added to round out the group.

In 1992, they released their independent album Be Ambitious with an accompanying video on Chainsaw Records. They were picked up by Epic/Sony Records and released their first major label single, Power of Love in 1993. Their first debut major label album, J.A.M, was released in 1994. With each release they grew in popularity until they became one of the most popular and well-known bands in Japan. One of their songs, Sobakasu, was used as the first opening theme for the popular and famous anime TV series Rurouni Kenshin and sold over 2 million copies.

In all, they released seven albums, three compilation albums and twenty-two singles. Judy and Mary broke up in March 2001 following the WARP Tour Final held at the Tokyo Dome, where fans bid them a tearful farewell. The concert is available on DVD.

Yuki is now enjoying a successful solo career, under the name YUKI. Takuya is also currently a solo artist. Onda has joined a new band called the Hot Rod Crue."
