Taiyou to Ciscomoon, 1999


On November 22, 1998, Tsunku announced on the TV show ASAYAN his idea for a new girl group. The audition, titled Tsunku Producer Geinoujin Atarashii Unit Audition, received a total of 500 applications. 8 candidates were selected as the finalists, with Inaba Atsuko, Kominato Miwa, Shinoda Miho, and RuRu passing the audition.


On February 21, 1999, the winners appeared on stage in the ASAYAN studio with the hosts. Here, Tsunku pointed out each member's weakness and said they were going to go back to the US for private lessons. He said Kominato needed to practice her dancing skills, RuRu her rhythm, and Inaba and Shinoda their singing. He also suggested names for the unit; Guts 1.2.3, Cisco3, Adult Queens, Morning Ookami (Morning Wolves), Moonlight Zoku (Moonlight Tribe), Taiyou to Moonlight Musume, Taiyou to Morning Ookami. He eventually chose the name Taiyou to Ciscomoon.

For three weeks, from February to March, ASAYAN covered the members' journeys. They were sent to four different cities: Inaba was sent to Atlanta (famous for gospel and soul), Kominato to Detroit (famous for Motown), Shinoda to Memphis (famous for southern blues music), and Honda to Chicago (famous for blues and rhythm). They spent three weeks improving themselves, with the final task being singing live. Kominato sang "A Deeper Love" and "Sotoyamabushi" (since her coach also wanted her to sing a minyo song) at Bakers Keyboard Lounge, RuRu sang "Hot Stuff" at a Chicago club, Shinoda sang at a service in a curch, and Inaba sang in the apartment for the people she had worked with.

From April 3 to April 17, they held their debut event in six different cities: on April 3 in Osaka, on April 6 in Takamatsu, on April 10 in Hiroshima, on April 14 in Yokohama, on April 16 in Kanazawa, and on April 17 in Nagoya.

On April 10, ASAYAN aired footage of Taiyou to Ciscomoon attending Morning Musume's concert in Fukuoka. It was announced that if Taiyou to Ciscomoon's debut single placed lower than Morning Musume's debut single (which placed #6), there was no point in continuing producing this group. They visited Morning Musume back stage after the concert, told them the news, and Morning Musume encouraged them to do their best.

On April 21, they released their debut single, "Tsuki to Taiyou".

On May 2, ASAYAN showed footage of Taiyou to Ciscomoon placed in a room wathcing the Oricon countdown from 30th place. They were surprised when MISIA's "Believe" placed #23, meaning their single placed higher. When they saw Tube's "Himawari" placed #7, they started crying, and didn't stop until they saw their single placed #4 when they started cheering.

On May 9, ASAYAN aired an episode where Tsunku announced the group was going on a single release spree, releasing four singles on the fly; one in June, one in July, one in August, and one in September. The next singles to be released was "Gatamekira", "Uchuu de La Ta Ta", "Everyday Everywhere" and "Magic of Love", followed by their debut album Taiyo & Ciscomoon 1 in October.

As annual school festival season was approaching, which would provide musicians with opportunities for small gigs, everything seemed to be going smoothly. However, there was one incident that changed the unit. They were told the restructuring plan to improve the quality of the unit. In order to become better performers with consistency and high skills, the agency asked Tsunku to reconsider the unit's dynamics. After examining videos from various school festivals, Tsunku made a decision to let go of Kominato. The decision would become in effect for the release of their next single.

On December 8, Taiyou to Ciscomoon released their sixth single, "Marui Taiyou -winter ver.-" as a trio, forcing Kominato on the sideline for all of Taiyou to Cicsomoon's activities during this period,[1] until she returned on January 3, 2000.

Kominato later said, in 2021, she was hospitalized due to stress of being temporarily withdrawn from the group (abdominal pain). [2]


When Kominato Miwa returned to to the group, the group’s name changed to "T&C Bomber".

On April 19, they releaesed their "DON'T STOP Ren'aichuu", their first single under the unit's new name.

In July 19, they released what would be their last single: "HEY! Mahiru no Shinkirou. The song was described by Tsunku as oriental funk, and had a new sound to it, similar to Heike Michiyo's "Murasaki Shikibu". It was featured in the movie Country Girl Hokkaido Bokujou Monogatari, in which T&C Bomber made a guest appearance.

On August 27, during ASAYAN, they released the news of the unit's upcoming disbandment in October[3]. The reason was so that each artist could focus on solo activities.

Shortly after the disbandment of the group, RuRu, Kominato, and Shinoda left the agency. Kominato had been asked to debut as a solo enka/minyo singer, but she chose to stay away from the major spotlight. Inaba however, stayed with the agency, and a new audition was announced, called Inaba Atsuko Shin Unit Audition. This ran from December 2000 up until May 2001, but the audition was unsuccessful and a new unit featuring Inaba was shelved.[5]
