Born on May 12, 2002, she was revealed as the group's 16th member in July 2023 and has since become a vocalist and dancer known for her bright, energetic stage presence. As part of TripleS, she has participated in multiple album releases, including the group's first studio album Assemble24, and the subsequent world tour. Her representative color within the group is Pastel Pink, and she is one of two Japanese members in TripleS, contributing to the group's international appeal. Standing at approximately 163 cm, she brings a distinctive presence to the group's performances.[edit]

Mayu was born in Japan on May 12, 2002, under the name Mayu Kawai. Details of her early childhood and education remain private, but she developed an interest in K-pop and performance during her school years. She later moved to South Korea to pursue training under Modhaus, the entertainment company behind TripleS. Her official unveiling as the 16th member of TripleS, designated S16, took place on July 19, 2023, through the group's Arrival content series. This reveal marked the beginning of her career as an idol, following a period of undisclosed training. Prior to her K-pop career, she lived in Japan and was a student, nurturing a passion for music and dance that eventually led her to audition for Modhaus.[edit]

Mayu made her official debut with TripleS shortly after her reveal in 2023, participating in the group's early promotions. Her first major comeback was with the album Lovestruck in January 2024, featuring the title track Girls Never Die. Later that year, she contributed to TripleS's first studio album Assemble24 and joined the group's first world tour, which included performances across the US, Europe, and Asia. As of 2026, she continues to promote actively with TripleS, focusing on group activities and subunit projects under Modhaus. She has also appeared in group pictorials and magazine features with TripleS, though she has not yet pursued notable solo projects outside the group.[edit]

Mayu is perceived by fans as a bright, energetic, and hardworking idol, fitting the youthful and girl crush concepts that TripleS explores. Her stage persona is cheerful and playful, often showcased in group variety content. As she does not maintain personal social media accounts, her public image is shaped through TripleS's official channels, where she appears as a lively and approachable member. The group's fandom, WAV, appreciates her for her consistent energy and contributions to the group's performances. She is often portrayed as having a cute, fresh aesthetic, and the media views her as a hardworking and integral member of the large-scale group project.[edit]

Mayu has cultivated a distinct resonance within the global K-pop landscape, though her standing reflects the unique structural dynamics of TripleS rather than individual chart dominance. As of August 2026, iFANN's Global Fame Engine has evaluated this person, but they do not currently hold a placement in the published rankings (Global Top 1,000 or a Top-100 scope list). This unranked status does not diminish her impact; instead, it highlights how her fame is deeply woven into the collective identity of the group and its sub-units. Her most significant viral moments, such as the June 2026 showcase where she laughed while confused by a Japanese language prompt, have humanized her presence for millions of viewers worldwide. These instances of genuine emotion often spark immediate discussion across social platforms, driving engagement that transcends traditional celebrity metrics. The fanbase surrounding Mayu is known as COSMOS, a highly organized community that actively participates in the group's evolution through voting and content creation. Fans have mobilized specifically to support her role as the final member of the EVOLution sub-unit, celebrating her reveal on July 19, 2023, with dedicated streaming campaigns for their mini-album ⟡(Mujuk). While no specific sub-fandom name exists exclusively for her, her contributions to major releases like Beyond Beauty and ASSEMBLE26 'LOVE & POP' are central to the group's narrative. Her recurring appearances at events like the LG Twins Victory Fairies further solidify her connection with sports-loving fans, creating a niche appeal that blends idol culture with local entertainment traditions.[edit]

Mayu stands as the second Japanese member to join TripleS, following Kotone, and brings a distinctive energy to the group's international lineup. Her representative color is Pastel Pink, and she is widely recognized for her cheerful, playful personality in variety content. Before her debut, she worked part-time in a restaurant, a story fans frequently cite as an inspirational tale of her perseverance from humble beginnings to stardom. She considers TWICE her role model and enjoys sushi as her favorite food, often spending her free time watching movies and listening to J-pop. A beloved piece of lore among the COSMOS community involves her performance of "Bubble Gum Girl" in November 2025 as part of the Sun unit, which marked a significant moment in the group's history. Another iconic memory is her appearance at the LG Twins' Victory Fairies ceremony in August 2026, where she joined fellow members Kwak Yeonji and others at Jamsil Baseball Stadium, cementing her image as a sports-loving idol. Though never officially designated as a main vocalist, a persistent belief among fans suggests she possesses hidden vocal talents, often handling important high-pitched parts that add a mysterious quality to her stage presence. Despite not maintaining personal social media accounts, she remains active on TripleS's official channels, engaging directly with her supporters.[edit]

Information about Mayu's family members, including parents and siblings, has not been publicly disclosed. She has not shared details about her household or pets in available sources. Her educational background is also not publicly documented.[edit]

Mayu is associated with the 23 other members of TripleS, including Seoyeon, HyeRin, JiWoo, Chaeyeon, Kotone, and SooMin. She is under the management of Modhaus, led by CEO Jaden Jeong, and works with producers such as BADD and El Capitxn.[edit]

Mayu has no publicly confirmed romantic relationships. As a relatively new K-pop idol, her dating life has not been the subject of credible reports or rumors. As of 2026, she is presumed to be single and focused on her career with TripleS. K-pop idols often keep their private relationships confidential, and there is no evidence of her being in a relationship.[edit]

Per iFANN's editorial analysis, Mayu's individual net worth is estimated at $400 Thousand as of 2026. Her primary income stream derives from her share of TripleS's extensive group activities, encompassing album sales, concert revenue generated during the world tour, and merchandise sales. She also benefits from group endorsement deals, although no specific brand partnerships have been publicly attributed to her individually. As a member of a mid-tier K-pop group, her earnings are supplemented by a fixed salary or settlement from Modhaus after expenses are recouped. This figure aligns with industry estimates for idols at a similar career stage, reflecting the typical financial trajectory for rookie-to-mid-level group members in the current market.[edit]
