In February, Miyoshi Chinatsu entered the 1st Morning Musume & Heike Michiyo Protegee Audition as one of over 3000 applicants, and became the winner. She was given a solo career within Hello! Project next to Nakazawa Yuko and Heike Michiyo. However, while Nakazawa released enka and Heike pop/rock, Miyoshi released up-beat ballads.

In August, she released her first single, Unchain My Heart. On the same date as its release, Hello! Project had a live concert TV broadcast called LIVE!! Summer Nite Town 99, where Miyoshi made her debut on stage.

In November, she released her second single, Love, Yes I do!. The song was used as the first ending theme for the anime Majutsushi Orphen: Revenge. The song also made it onto two compilation albums for the anime.

That same year, a TV show called THE GARAGE started airing on TV Tokyo. Each month the show featured a different theme song, and it was sung by different members of Hello! Project. A music video was made for each theme song, and Miyoshi was featured in "Tunnel Tengoku" for February, and "Blue Chateau" for March. Four CD singles containing all the theme songs were also released, and Miyoshi was featured on vol 4.


Miyoshi participated in all the concerts Hello! Project held in 1999 and 2000. She also appeared on the TV shows Idol wo Sagase and Hello! Morning, and starred in the movie Pinch Runner alongside Morning Musume.

In May, Miyoshi released her third single, Anata no Shirts to Love song. The lyrics for this song was written by Miyoshi herself.

In September, Miyoshi appeared in what would be her last concert. The official reason for her departure was that she would like to look at herself objectively, and have more variety of experience. It was speculated that the real reason was that she was dismissed due to monetary issues with the office. There were rumors that she was either the former lover of the person who was in the office, or the lover of someone who had the trouble with the office.


In September, Miyoshi began to show her face to the public again and began taking up acting, singing, and dancing lessons.


In 2005, Miyoshi re-entered the music scene when she contributed to a soundtrack to a horror movie called Kokkuri-san. Upon her return, she changed her name to Tani Rumiko, being both a solo artist and in a band called march. The band is made up of Tani and Sun (a Korean artist).


In August, she and Korean pop singer Kim Jung Min (real name Kim Jung Soo), who she had been dating, announced their engagement, they married on October 21. She claimed South Korean citizenship and currently resides in South Korea. They have since had three children together.
