Early LifeEdit

Mari Yaguch was born on January 20, 1982 in Kanagawa, Japan.


On May 3, she, along with Kei Yasuda and Sayaka Ichii, were chosen to be a part of the second generation of singers to be recruited into Morning Musume.

On November 18, she debuted with Morning Musume's first sub-group, Tanpopo.

She made her movie debut in the film Morning Cop, alongside the other Morning Musume members and Hello! Project soloist Heike Michiyo.

On October 20, she created and formed Morning Musume's sub-group Minimoni. She had an idea for a sub-group whose members were 1.5 m (4 ft 11 in) in height or shorter. Yaguchi, and Morning Musume's songwriter and producer Tsunku, selected two of Morning Musume's newest members Ai Kago and Nozomi Tsuji, for the new sub-group and the trio began performing in concerts as Minimoni. American-born Mika Todd, of Coconuts Musume, was later added into the group to give the group "an international flavor" and Tsunku made them official.

Their debut single, Minimoni Jankenpyon! / Haru Natsu Aki Fuyu Daisukki!, was a #1 hit.


On February 7, she released her first photobook titled Yaguchi.

She starred in another film called Nama Tamago alongside Kaori Iida, Nozomi Tsuji, & Maki Goto. The film was released in VHS format on March 15 and later in DVD format on May 15.

Yaguchi became Morning Musume's sub-leader in May, after the graduation of Kei Yasuda.

On March 29, she graduated from Minimoni, having Mika Todd replace her as the leader. The group lasted another year until Mika Todd's graduation from the group and Hello! Project altogether.

In July, she debuted with ZYX as leader. In ZYX, Yaguchi acted as a mentor to the Hello! Project Kids, showing them the ropes of being a performing member of Hello! Project. ZYX was the first unit that Hello! Project Kids officially joined.

She also made a guest appearance in one episode of the drama Kochira Hon Ikegami Sho.

She released two more photo books, one titled Love Hello! Mari Yaguchi, part of an idol DVD she had. The other being Pocket Morning Musume, Volume 2, which also featured Natsumi Abe, Maki Goto, and Kaori Iida.

On October 10, she released her first essay book entitled Oira - MARI YAGUCHI FIRST ESSAY.

On January 30, after the graduation of Kaori Iida, Yaguchi became leader and Hitomi Yoshizawa then became her support as sub-leader.

On April 14, it was reported by tabloid magazine FRIDAY that Yaguchi was in a relationship with actor Oguri Shun. She said she had "betrayed [her] position as an idol" and that she "want[ed] to move on with [her] career as an adult." As such, Yaguchi resigned from Morning Musume without a graduation ceremony.

Her first post-Morning Musume recording, Nigiyaka na Fuyu, done as a collaboration with Berryz Koubou, appears as the coupling track on Berryz Koubou's November 2005 single Gag 100kaibun Aishite Kudasai.

In February, Yaguchi announced on her blog that she was opening a restaurant called Shabushabu Onyasai Roppongi. The restaurant opened on March 19. She mentioned on her blog that she was fussing about the interior design, sampling food from the new menu, suggesting new menu ideas, working on staff uniforms and even working on a new uniform for her, so it seems that the restaurant was suited to Yaguchi’s personality.

In mid-May, multiple news agencies and magazines reported that Yaguchi had an affair and was cheating on her husband. It was also reported that she and her husband got into an argument on whether or not to have a child, and the two were now living apart. Nakamura Masaya's agency confirmed that the two were fighting, but that they were not getting a divorce. According to reports, Masaya caught Yaguchi sleeping with another man, Kenzo Umeda, back in February. Umeda immediately deleted his blog and Twitter account and Yaguchi apologized to the public. Yaguchi was thereafter seen without her wedding ring.

Umeda was told to kneel down and bow while Nakamura took a photo of him for evidence. Nakamura said that "Our bed sheets were always changed to new ones whenever I came back home from other locations." Yaguchi has since left three TV shows that she was a regular on.
