Urai, working originally as a graphic designer, decided to find a new career in professional wrestling after becoming a fan of the likes of Keiji Mutoh, Satoru Sayama, Yoshiaki Fujiwara, Antonio Inoki, Akira Maeda, Nobuhiko Takada, Masakatsu Funaki, Volk Han and Minoru Suzuki.

[11][12] Trained by Yuki Ishikawa,[10] Urai adopted the ring name Kana and made her professional wrestling debut for all female promotion AtoZ on June 16, 2004, in a match against Leo-na.

[29][30][31] On April 21, Kana and Mio Shirai defeated Misaki Ohata and Tsukasa Fujimoto to win the Wave Tag Team Championship, bringing Triple Tails.S its first title.

[35] On July 12, the White Tails stable produced their final event before the group's dissolution, during which Kana wrestled the soon-to-retire Ayumi Kurihara to a ten-minute time limit draw.

[40] The team made it all the way to the finals of the tournament, before losing to Las Aventureras (Ayako Hamada and Yuu Yamagata) in a three-way match, which also included Muscle Venus (Hikaru Shida and Tsukasa Fujimoto).

[70][71] Following the win, Kana, portrayed as the villainous outsider, smeared makeup on Nakajima's face, before gloating over capturing JWP's top title during Plum Mariko's memorial event.

[85] On April 16, Kana took part in a rare women's match promoted by Pro Wrestling Noah, defeating JWP representative Rabbit Miu.

[89][90] Kana announced that she would go on an indefinite hiatus from professional wrestling[91][92] following KanaProMania: Pulse on September 15; in her last match she teamed with Hikaru Shida and Syuri in a winning effort against Arisa Nakajima, Rina Yamashita and Ryo Mizunami.

[95] As part of the attempt to get her over as the top villain, Kana wrote a manifesto for the Weekly Pro-Wrestling magazine, which was published on August 4 and where she attacked the entire Joshi Puroresu community, claiming it was full of wrestlers with no personality and bad attitudes and who wrestled in an unrealistic manner.

[102] Kana then continued working against the opposite sex, teaming with the Shirais to defeat Tajiri, Ken Ohka and Yoshiaki Yago on February 25,[103] but losing to Funaki on March 31.

[115] On August 3, 2011, it was reported that Kana would be making her debut in the United States in early October, working for all-female promotion Shimmer Women Athletes on 1 and 2 and for Chikara on 7 and 8.

[116][117] In her Shimmer debut on Volume 41, Kana was shown in early segments ignoring Sara Del Rey and Cheerleader Melissa's welcoming, establishing herself as a villain in the process.

[145][146] For the first time since 2006, when she was affiliated with AtoZ, Kana signed a contract to make WNC her new home promotion, ending her freelancing days, though the deal allowed her to continue working for Pro Wrestling Wave and producing her own independent events.

[163] During a press conference the following day, Kana and Makoto announced that they were coming together to produce an event at Shinjuku Face on November 9, celebrating their common birthday, respectively.

[182][183][184] On January 12, 2015, Kana and Nakajima made their first successful defense of the Reina World Tag Team Championship against Goya Kong and Muñeca de Plata.

Asuka saved Carmella from a post-match attack by Eva Marie and Nia Jax and afterwards had a staredown with Bayley, indicating that she wanted a shot at her title.

[218] After her successful title defense against the returning Mickie James on November 19 at NXT TakeOver: Toronto, Asuka displayed the first signs of villainous behavior when she refused to shake her opponent's hand after the match.

[229] Asuka also attacked Ember Moon, Nikki Cross and Ruby Riott, who were the final competitors in a battle royal to determine her challenger for NXT TakeOver: Chicago, officially cementing herself as a villainess.

[262][263] With wins over Carmella and Big E, Sasha Banks and Finn Bálor,[264][265] Alexa Bliss and Braun Strowman[266] and finally Charlotte Flair and Bobby Roode, they won the tournament.

[269] On April 17, Asuka was drafted to SmackDown as part of the 2018 WWE Superstar Shake-up, making her first appearance by saving Charlotte Flair and Becky Lynch from an attack by The IIconics (a duo made of Billie Kay and Peyton Royce) and then—SmackDown Women's Champion Carmella.

[295] Dave Meltzer said she was supposed to defend the SmackDown Women's Championship at WrestleMania 35 against the winner of a fatal four-way match between Carmella, Mandy Rose, Naomi, and Sonya Deville that was cancelled in the last minute.

[296] On the April 16, 2019, episode of SmackDown, Paige announced that she would be managing a newly formed women's tag team, consisting of Asuka and the debuting Kairi Sane from NXT.

[307] The next night on Raw, The Kabuki Warriors completed their transition into heels, as they cut a promo on both Becky Lynch and Charlotte Flair and went onto defeat them in a non–title match, once again using green mist as leverage.

[315] On the first night of WrestleMania 36, The Kabuki Warriors lost the WWE Women's Tag Team Championship to Alexa Bliss and Nikki Cross, ending their reign at 181 days, the longest of the title so far.

[321] The next night on Raw, Stephanie McMahon ruled that the result was reversed to a no-contest, meaning that Asuka retained the championship, despite Banks having taken possession of the actual belt.

[337] On the June 21 episode of Raw, Asuka and Naomi qualified for the women's Money in the Bank ladder match by defeating the team of Eva Marie and Doudrop (Piper Niven).

[348] On the October 31 episode of Raw, Asuka and Alexa Bliss defeated women's tag team champions Dakota Kai and Iyo Sky in a title match and won the championship.

[citation needed] Asuka and Sane went on to retain their titles against Chance and Carter on the February 5 episode of Raw and against Candice LeRae and Indi Hartwell on the Elimination Chamber: Perth kickoff show.

On Night 1 of WrestleMania XL, Damage CTRL (Asuka, Sane, and Kai) were defeated by Belair, Naomi, and Jade Cargill in a six-woman tag team match.
