On November 18, she debuted with Morning Musume's first sub-group, Tanpopo.
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, Kago Ai and Tsuji Nozomi, 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.
Yaguchi also had a supporting role in another film called Pinch Runner alongside the other Morning Musume members.
On February 7, she released her first photobook titled Yaguchi.
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! Yaguchi Mari, part of an idol DVD she had. The other being Pocket Morning Musume, Volume 2, which also featured Abe Natsumi, Goto Maki, and Iida Kaori.
On October 10, she released her first essay book entitled Oira - MARI YAGUCHI FIRST ESSAY.
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 April, it was reported that Yaguchi and Oguri broke up.
In 2006, she continued to appear on television and at live events on behalf of Hello! Project. She also co-hosted two weekly TV shows of her own (Yaguchi Hitori and Kanrui! Jikuu Times) starred in two dramas, and frequently guest starred on other variety shows.
At the start of 2007, she started to perform during Hello! Project concerts again.
In Summer, Yaguchi was cast to host a new Gyao TV show, Midtown TV, thus appearing in a third TV show on air. Midtown TV aired on weekdays and Yaguchi hosted it on Thursdays. Also, Mari and seven H!P Eggs appeared live and with an audience on Ciao TV, a Kids Station show, on September 2, from 19:00 to 19:30, on what appeared to be yet another new TV show for her, which made four Yaguchi Mari TV shows being aired simultaneously.
Yaguchi appeared in a Japanese drama series called Sento no Musume!?. She was one of the main stars in a Japanese day time drama series called Gyarusa, along with her show Yaguchi Hitori, and being an MC at Hello! Project concerts.

On April 27, Yaguchi participated in an event for Minna no Fitness, a free internet workout.
She graduated, with the rest of the Elder Club, at a graduation concert held at Yokohama Arena on February 1.
Yaguchi Mari's first solo single debuted live on the TV show Quiz Hexagon, which also brought about popular groups Pabo and Shuchishin. The CD single was a collaboration with AIR BAND and included a randomly chosen photo card of either Mari or AIR BAND. It was an emotional performance for Mari who had not performed on live television in over four years.
In April, it was announced that Yaguchi would be writing a blog-like column in Famitsu, one of the most respected video game magazines in Japan and the world. She would be talking about how girls are also passionate gamers. The column also featured photos of Yaguchi. The column was originally released on May 1. The column was titled "I’m a Gamer".
In November, Yaguchi Mari was rendered into a CG character for the video game Ryuu ga Gotoku: Densetsu wo Tsugumono (known as Yakuza 4 outside of Japan).
In December, the cover for Yaguchi Mari to Straw Hat’s single, titled "Kaze wo Sagashite", was released. "Yaguchi Mari to Straw Hat" was the name of the Hexagon family unit for the song which featured Yaguchi as the main singer. The song was used for the opening of the anime One Piece.
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.

Also in March, Yaguchi opened up a Gree blog.

On August 7, Mari joined the new promotional unit Afternoon Musume with seven other OG members to promote Georgia coffee drinks.
On January 2, some media outlets reported that Yaguchi Mari would be getting married to her boyfriend, actor Nakamura Masaya. According to a related source, Yaguchi already said that she would be getting married, and now she needed to report her marriage and decide the day to register the marriage.
On May 21, it was announced that she would register her marriage to Nakamura Masaya on May 22. Originally, the couple planned to marry in March but, due to the earthquake, their plans were postponed.
On May 22, a year after registering their marriage, Yaguchi Mari and Nakamura Masaya held a wedding ceremony at St. Grace Cathedral in Aoyama. She has changed her name to Nakamura Mari, but continued to use "Yaguchi Mari" as her stage name.
On March 2 and 3, Yaguchi participated in the Forest For Rest ~SATOYAMA e Ikou~ SATOYAMA movement in YOKOHAMA along with other Hello! Project and UP-FRONT PROMOTION members.
From April 4 to April 9, Yaguchi performed in the stage play Ikinuku Kiseki ~Juu Nenme no Negai~.
In mid-May, multiple news agencies and magazines reported that Yaguchi was having an affair. 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, Nakamura (27) caught Yaguchi (30) sleeping with another man, model Umeda Kenzo (25), back in February. Umeda immediately deleted his social media accounts and retired from modeling, while Yaguchi apologized to the public. Yaguchi was thereafter seen without her wedding ring.
On May 21, she was seen at the Morning Musume Concert Tour 2013 Haru Michishige☆Eleven SOUL ~Tanaka Reina Sotsugyou Kinen Special~, watching Tanaka Reina's graduation.
On May 30, it was announced that Yaguchi and Nakamura Masaya had submitted their divorce papers, and Yaguchi claimed there was domestic violence in their relationship. According to new details, Nakamura came home on February 23, and saw what looked like a bedroom that was just used for sex. Amid further inspection, Nakamura found Umeda hiding in the closet naked, who was then told to kneel down and bow while Nakamura took a photo for evidence. Nakamura was quoted as having said, "Our bed sheets were always changed to new ones whenever I came back home from other locations."
Yaguchi had since left three TV shows that she was a regular on.
On July 8, Tokyo Sports reported that she was currently living with Umeda and that she was planning to make a comeback later that year and make a public apology.
In the Josei Jishin August issue, Yaguchi's acquaintance said she would make her comeback once the issue died down. She apparently stated that she would return within the next 5 years (by 2019). It was rumored that she had 100 million yen in savings.
On October 1, she was transferred to UP-FRONT CREATE.
On October 13, she blogged that she was going on an indefinite hiatus. She hoped to return to show business one day.
On October 23, Yaguchi appeared on Miyaneya, an afternoon tabloid television show.
In November, Yaguchi started blogging for the first time since her hiatus announcement.
In April, it was announced that she had joined a girl group with fellow Morning Musume graduates Takahashi Ai and Tsuji Nozomi called "Datsumo Musume", under the management of Datsumo Labo for the promotion of their hair removal services.
On March 13, it was reported that she would be marrying a 30-year old former male model sometime in the near future, possibly as soon as that month. The next day, Nikkan Sports reported that the couple, who had been dating for the past four years, set their marriage date for March 26. These reports were confirmed, when on March 26, Yaguchi officially announced on her blog that she had remarried.
On March 27, she began a live variety talk show on AbemaTV's The NIGHT channel, titled Yaguchi Mari no Kayou The NIGHT, with comedian Okano Yoichi as her assistant MC and various idols as guests.
During the live broadcast of Yaguchi's AbemaTV show Yaguchi Mari no Kayou The NIGHT on April 2, she announced that she and her husband held a private ceremony in Okinawa last month on their first anniversary, confirming a report made by Josei Jishin earlier in the week, and that she was pregnant with her first child who was due to be born in the summer.
On February 29 Yaguchi and Yasuda Kei were scheduled to hold a live event called "M-line club 10 Shuunen Kikaku 'Yasuda Kei, Yaguchi Mari' FC Event" (M-line club 10周年企画「保田圭・矢口真里FCイベント」), but it was later cancelled due to the coronavirus.

- Yaguchi was the first Morning Musume member to "resign" due to a scandal. She received no graduation concert or final performances because of this, but she made it clear that she would return as a solo artist in 2006.
- She was famous for her "Sexy Beam!" line from "Koi no Dance Site" and she was asked jokingly in the Morning Musume single Joshi Kashimashi Monogatari, "When will your real sexy beam come out?" The "Sexy beam!" line has made its way around fans and fellow musicians alike.
- After being out of Morning Musume for a time, she often came out and discussed how Tsuji Nozomi terrorized her in Minimoni and Morning Musume and also said whenever she sees her cry, even to this day, she was not affected by it and thinks she is faking.
- She is known for her exuberant and irreverent personality.
- She was also famous for being the smallest member of Morning Musume at only 145 cm (4 ft. 9 in.) and 39 kg (86 lbs.).

- When she resigned from Morning Musume, she was the last person to leave that joined before the year 2000 (Iida Kaori had left about 2 months before).
- Her new focus on television prompted Yaguchi, during an interview with actor Hugh Jackman, to jokingly describe herself as a "variety idol." Although she later regretted the joke — because she tried to distance herself from her idol image — the nickname has stuck among her fans.
- She was the sixth former Morning Musume member to get married, the first being Ishiguro Aya, second being Ichii Sayaka, third being Iida Kaori, fourth being Tsuji Nozomi, and fifth being Fujimoto Miki.

- She was the second former Morning Musume member to be divorced. The first former Morning Musume member to divorce was Ichii Sayaka, who was from the same generation as her.
- Tsunku said in an interview in 2012, that the main reasons for Yaguchi being selected was that she was one of the first to send in her application (among thousands) and because of her height.
- She shares the same last name with former Gatas Brilhantes H.P. player Yaguchi Megumi.
