The Wave Single Championship (WAVE認定シングル王座, Wēbu-nintei Shinguru Ōza) is a women's professional wrestling championship owned by the Pro Wrestling Wave promotion. The title is nicknamed and more commonly referred to as the Regina di Wave Championship (Regina di WAVE王座, Rejīna di Wēbu Ōza; Italian for "Queen of Wave").[5][1] The championship, which is situated at the top of Pro Wrestling Wave's championship hierarchy, was first announced on December 5, 2012.[1] The inaugural champion was crowned on March 17, 2013, when Yumi Ohka defeated Kana in the finals of a five-woman tournament.[2]
There have been a total of 24 reigns shared between 16 different wrestlers. Itsuki Aoki is the current champion in her first reign.
History
[edit]On December 5, 2012, Pro Wrestling Wave's founder and booker Gami announced the creation of the Wave Single Championship.[1] Prior to the announcement, Wave, which was founded in August 2007, had no singles championships; instead the annual Catch the Wave tournament served as the promotion's top singles achievement.
Regina di Wave tournament
[edit]
Gami then announced that the inaugural champion would be determined in a four-woman single-elimination "Regina di Wave" tournament, which would include three former winners of Catch the Wave; Ayumi Kurihara (winner of the 2012 tournament), Kana (2011) and Yumi Ohka (2009), and the winner of a one-night Zan-1 tournament, a three-round tournament, which included a battle royal, a rock-paper-scissors round and a fan vote. Gami herself was also a former Catch the Wave winner from 2010, but decided not to put herself in the title tournament.[1] On December 16, Misaki Ohata won the Zan-1 tournament to earn the fourth and final spot in the title tournament.[6][7] On January 23, 2013, a random draw decided that in the first round of the tournament on February 17, Ayumi Kurihara would face Kana, while Misaki Ohata would face Yumi Ohka.[8][9] The finals of the tournament were set to take place on March 17.[7] On February 16, Wave announced that Kurihara had suffered a nasal and orbital floor fracture and would be forced to pull out of the tournament.[10][11] She would be replaced by Mio Shirai, who had finished second in the Zan-1 tournament.[11] In the following day's semifinal matches, Kana defeated Shirai, while Ohka defeated Ohata. However, it was announced that if Kurihara was able to return to the ring by March 17, she would get to wrestle Kana for a spot in the finals.[12][13][14][15] On March 7, Kurihara announced that she was going to make her return for the match against Kana. In order to prevent Ohka from having the advantage of having to wrestle only one match on March 17, she was put in a non-tournament match against Gami.[16] On March 17, Kana defeated Kurihara to hold on to her spot in the finals of the tournament.[2] Later that same day, Ohka defeated Kana in the finals to win the tournament and become the inaugural Wave Single Champion.[2][17][18]

Championship Overview
Establishment and Inauguration
On December 5, 2012, Pro Wrestling Wave founder and booker Gami announced the creation of the Wave Single Championship (officially known as the Regina di WAVE Championship), positioning it as the promotion's premier women's singles title.[1] This decision came amid the promotion's expansion since its founding in 2007, aiming to crown a definitive top singles competitor in a landscape dominated by tag team and multi-woman formats.[4] To determine the inaugural champion, Wave organized a four-woman single-elimination tournament featuring Yumi Ohka, Kana, Ayumi Kurihara, and Misaki Ohata, with the latter two having qualified through the preceding Zan-1 tournament. The semifinals took place on February 17, 2013, during WAVE Sunday Wave Vol. 13, where Yumi Ohka defeated Ayumi Kurihara and Kana defeated Misaki Ohata.[5] The tournament culminated on March 17, 2013, at WAVE Sunday Wave Vol. 14 in Tokyo, Japan, with Yumi Ohka defeating Kana in the final match lasting 15:04 to become the first champion.[6] The initial belt, presented immediately following the match, featured a classic design with a central gold plate engraved with the title name in elegant script, flanked by side plates depicting wave motifs symbolizing the promotion's identity, and a red leather strap for distinction.[1]Prestige and Current Status
The Wave Single Championship, formally designated as the Regina di WAVE Championship, stands as the highest honor in Pro Wrestling Wave's singles division, symbolizing the promotion's reigning "queen" through its Italian nomenclature, which directly translates to "Queen of Wave." This title underscores a wrestler's dominance and leadership within the joshi wrestling landscape of the promotion, often defended in high-stakes matches that highlight technical prowess and narrative depth.[7] Deeply integrated into Pro Wrestling Wave's annual calendar, the championship frequently culminates major events such as the Catch the Wave tournament, where the victor earns a coveted title opportunity, positioning the belt as the ultimate prize for emerging talents and established stars alike. This structure not only elevates the tournament's competitive intensity but also ensures the title remains central to the promotion's storytelling and fan engagement.[8] As of November 19, 2025, Itsuki Aoki holds the Wave Single Championship in her first reign, having defeated Cohaku on November 2, 2025, at the PRIME WAVE '25 event in Tokyo's Korakuen Hall, marking a reign duration of 17 days with no successful defenses to date. Aoki's victory ended Cohaku's reign, showcasing Aoki's resilience in a 19-minute, 17-second bout decided by a Japanese Ocean Backdrop Hold. No formal challenges have been announced under Aoki's reign thus far, though the promotion's ongoing schedule suggests potential contenders from recent tournament outcomes.[3][7] Overall, the title has seen 24 reigns distributed among 16 distinct wrestlers since its inception, accompanied by two vacancies due to injury or storyline circumstances, reflecting its enduring legacy and the promotion's commitment to competitive evolution. The inaugural champion, Yumi Ohka, set the foundation for this prestigious lineage in 2012.[7]Historical Development
Regina di Wave Tournament
The Regina di Wave Tournament was a single-elimination competition featuring four wrestlers, held in early 2013 to crown the inaugural Wave Single Champion within Pro Wrestling Wave. Announced by promotion founder Gami on December 5, 2012, the event aimed to establish a premier singles title and spotlight top talent in Japanese women's professional wrestling. Misaki Ohata secured her participation by winning the preceding Zan-1 qualifying tournament on December 16, 2012. The bracket originally included Ayumi Kurihara, but due to her nasal and orbital floor fracture sustained in an Oz Academy match on February 15, 2013, she was replaced by Mio Shirai. The semifinals occurred on February 17, 2013, at the WAVE Sunday Wave Vol. 13 event in Tokyo, Japan. In the first match, Yumi Ohka defeated Misaki Ohata via pinfall after 20 minutes and 17 seconds, showcasing Ohka's technical prowess and endurance. The second semifinal saw Kana, an emerging striker known for her hard-hitting style, overcome Mio Shirai with a pinfall victory in 11 minutes and 26 seconds. These bouts highlighted the tournament's blend of veteran experience and youthful aggression, drawing an attendance of 432 spectators. The tournament final took place on March 17, 2013, at Shinjuku FACE in Tokyo, where Yumi Ohka faced Kana in a highly anticipated clash. Ohka emerged victorious by submission, applying a decisive hold to force the tap-out and becoming the first Wave Single Champion. This outcome underscored Ohka's versatility in grappling and striking, solidifying her status as a cornerstone of the promotion. The Regina di Wave Tournament laid the competitive groundwork for the Wave Single Championship, introducing a structured pathway for title contention and elevating rising stars like Kana, who would later achieve international acclaim. By emphasizing high-stakes matches among diverse wrestling styles, it established the title as a symbol of excellence in joshi puroresu, influencing subsequent defenses and storylines in Pro Wrestling Wave.Major Title Changes and Vacancies
The inaugural champion Yumi Ohka held the Wave Single Championship—also known as the Regina di WAVE Championship—for a record-setting 525 days before losing it to Hikaru Shida on August 24, 2014, at a Pro Wrestling WAVE event in Tokyo, marking the title's first major transition and elevating Shida's profile within the promotion.[1][9] The championship experienced its first vacancy on December 29, 2018, when Misaki Ohata won the title from Ryo Mizunami in her retirement match but vacated it immediately afterward due to her departure from professional wrestling, resulting in a 198-day period without a champion that disrupted regular title storylines and prompted Pro Wrestling WAVE to reorganize booking around interim attractions; the title was reactivated on July 15, 2019, when Rina Yamashita defeated Shuu Shibutani in a tournament final to become champion.[1][10] The second vacancy occurred on July 17, 2022, following Nagisa Nozaki's 329-day second reign, as she was forced to relinquish the belt due to a legitimate ruptured ACL injury sustained earlier, though the promotion swiftly resolved it the same day by awarding the title to Suzu Suzuki in the Catch the Wave 2022 final against Miyuki Takase, minimizing long-term booking interruptions through integration with the ongoing tournament.[1][11][12] In recent years, the title has seen dynamic shifts, including Saya Kamitani's victory over Yuki Miyazaki on November 4, 2024, at WAVE Prime Wave 2024, ending Miyazaki's 316-day reign and positioning Kamitani as a bridge between Stardom and WAVE; Kamitani then lost the championship to Cohaku on August 10, 2025, at a Korakuen Hall event, only for Cohaku to drop it to Itsuki Aoki on November 2, 2025, during WAVE Prime Wave 2025, highlighting the promotion's emphasis on emerging talent in high-stakes matches.[1][13][14][3][15] Title defenses have evolved to become fixtures in Pro Wrestling WAVE's flagship events, such as the Catch the Wave singles tournament—where finals frequently determine or contest the championship—and the Dual Shock Wave tag team tournament, allowing champions to showcase the belt alongside partner-based narratives and cross-promotional rivalries, thereby enhancing its prestige and integration into the promotion's annual cycle.[1][16] These vacancies and changes have influenced booking by necessitating adaptive tournaments, like the post-retirement contendership arcs and injury-prompted finals, which maintain momentum and spotlight new contenders without extended downtime.[12][1]List of Champions

Combined Reigns
The combined reigns of the Wave Single Championship represent the aggregate tenure and achievements of each wrestler across all their individual title holds, calculated by summing the days from each reign while excluding any vacancy periods. This metric highlights career-long contributions to the title's legacy, with total defenses reflecting successful matches during those periods. Nagisa Nozaki holds the record for the longest combined reign at 693 days over two reigns, with 9 defenses.[19] Yumi Ohka, a foundational figure in Pro Wrestling Wave, has accumulated significant combined time through her two reigns, underscoring her enduring impact.[20] Wrestlers like Misaki Ohata, with three reigns, exemplify the title's history of repeat champions building extended tenures.[20][21]| Wrestler | Total Reigns | Total Days as Champion | Total Defenses |
|---|---|---|---|
| Nagisa Nozaki | 2 | 693 | 9 |
| Hikaru Shida | 2 | 584 | 11 |
| Yumi Ohka | 2 | 547 | 8 |
| Yuu Yamagata | 1 | 368 | 7 |

Records and Statistics
Reign Duration Records
The longest individual reign in the history of the Regina di Wave Championship—more commonly known as the Wave Single Championship—belongs to inaugural champion Yumi Ohka, who held the title for 525 days from March 17, 2013, to August 24, 2014.[1] This extended tenure, established through a tournament final victory over Kana, showcased Ohka's dominance in Pro Wrestling Wave during the promotion's early years as a singles title holder.[22] In contrast, the shortest reign occurred during Misaki Ohata's third stint as champion, lasting less than one day on December 29, 2018, before the title was vacated due to her immediate retirement announcement.[1] Ohata, a three-time champion overall, had won the belt just hours earlier in a match against Ryo Mizunami, but her sudden exit from wrestling truncated what could have been another significant run.[1] Among other notable records, Suzu Suzuki became the youngest champion at 19 years old when she captured the title on July 17, 2022, by defeating Miyuki Takase in the final of the Catch the Wave tournament for the vacant title (Nagisa Nozaki had relinquished it due to injury)—marking a milestone for emerging talent in the joshi wrestling scene.[12][23] At the opposite end, Yuki Miyazaki holds the distinction of the oldest champion, winning the title at 44 years and 10 months old on December 24, 2023, in a victory over VENY, and maintaining the reign through high-profile defenses into 2024.[1][24] Reign durations in the Wave Single Championship have been influenced by various factors, including sudden retirements like Ohata's, prolonged injury-related vacancies—such as the 198-day period following her departure—and the demands of high-profile defenses against international and domestic challengers, which often test champions' endurance and lead to shorter or extended holds depending on the competitive landscape.[1]| Record Type | Wrestler | Duration/Details | Date(s) |
