Shiori Tamai

Shiori Tamai is a Japanese singer and actress best known as the "Yellow" member of the iconic J-pop girl group Momoiro Clover Z. Born in Kanagawa Prefecture, she has maintained a high-profile career for over two decades, transitioning from a child actor to a seasoned idol and voice actress. As of 2026, she remains an active performer with the group while pursuing solo ventures in voice acting and variety shows.

Tamai stands out within the idol landscape for her longevity and versatility. Unlike many peers who retire after a few years, she has navigated the industry through significant shifts in pop culture, maintaining relevance through energetic stage performances and diverse media appearances. Her public persona blends youthful charm with professional resilience, evidenced by her ability to handle demanding schedules ranging from concert tours to complex voice acting roles in major anime franchises.

Shiori Tamai entered the entertainment world at an exceptionally young age, starting her career as a child actor when she was just four years old. During these formative years, she appeared in various television commercials and took on minor roles that provided early exposure to the performance arts. Her talent and work ethic led to her signing with Stardust Promotion in 2008, a pivotal moment that set the stage for her future success.

The path to stardom required balancing education with a rigorous training schedule. Like many Japanese child stars, Tamai likely attended part-time schooling or correspondence courses to accommodate her growing commitments. Her time at Stardust Preparation focused heavily on refining her singing, dancing, and acting skills. This intensive preparation culminated in her selection as one of the five founding members of Momoiro Clover Z, a group formed through a unique audition process designed to blend traditional idol aesthetics with rock and electronic music influences. [edit]

Momoiro Clover Z officially debuted in 2010, marking the beginning of Tamai's rise as a leading figure in the Japanese idol scene. The group quickly gained traction with their energetic "rock idol" concept, selling out major venues including Tokyo Dome by 2012. Tamai played a central role in these performances, establishing herself as a core component of the group's dynamic energy.

Beyond her work with the group, Tamai successfully expanded into voice acting and film. In 2015, she voiced characters in *Dragon Ball Z: Resurrection 'F'* and appeared in the live-action film *The Curtain Rises*. Her vocal talents were further showcased when she contributed to the opening theme for the long-running anime *Chibi Maruko-chan* in 2019. She continued to take on diverse roles, voicing ghosts in *Layton Mystery Tanteisha* and appearing in the Nippon Television series *Akumu-chan* in 2022.

Recent years have seen Tamai solidify her status as a veteran artist. In 2025, she featured on the Studio Ghibli tribute album *Ghibli wo Utau Sono 2*, demonstrating her mature vocal range in orchestral settings. Despite facing health challenges like testing positive for COVID-19 in 2021 and sustaining a finger injury later that year, she continued to perform, highlighting her dedication to her craft. Her career remains active as of 2026, with ongoing participation in festivals and new music releases. [edit]

Shiori Tamai projects an image of energy, playfulness, and professionalism. Known for her bright personality, she often incorporates humor into her performances, a trait that resonates well with her fanbase. Her style typically features colorful, youthful fashion that aligns with the group's vibrant aesthetic, yet she adapts her look to suit more mature roles in voice acting and dramatic projects.

Media portrayals emphasize her transition from a child actor to a versatile adult artist. She is viewed as a resilient figure who has navigated the pressures of fame while maintaining her enthusiasm for performing. Her commitment to physical fitness and dance allows her to sustain the high-energy routines required by Momoiro Clover Z, reinforcing her reputation as a dedicated professional. [edit]

Shiori Tamai has cultivated a devoted following over more than a decade as an original member of Momoiro Clover Z. Her journey from a child actor at age four to a seasoned performer in her thirties has created a narrative of longevity that resonates deeply with fans who have watched her evolve alongside the group. While the collective energy of the Momoiro Clover Z fandom is legendary for its organized chart pushes and vibrant culture, specific documentation of a formal name for Tamai's individual fanbase remains absent from public records; the fanbase has no formal name.

The audience celebrates her distinct yellow image color and solo projects like the photo book Tamayura, yet no unique rituals or exclusive campaigns are widely attributed solely to her outside the broader group activities. Iconic moments tied to her persona include her memorable appearance in Pikotaro's "Vegetable" music video, where she playfully slapped the singer, and her role as a ghost in the anime Layton Mystery Tanteisha. Health challenges during the pandemic and a notable finger injury on stage have been met with concern rather than becoming viral folklore, grounding her story in resilience rather than myth.

Despite her enduring presence in the industry, including upcoming features on the Ghibli wo Utau Sono 2 album, she does not currently hold a placement in the published Global Top 1,000 rankings. Shiori Tamai is currently evaluated by iFANN but holds no placement in the Global Top 1,000 or any Top-100 scope list. She is not on the August 2026 iFAMOUS Rankings flagship list. [edit]

Shiori Tamai is widely recognized by her nickname "Shiorin," a moniker used affectionately by fans and fellow group members. While some sources list Tanegashima as her birthplace, official biographical data consistently cites Kanagawa Prefecture. Her official image color within Momoiro Clover Z is yellow, distinguishing her visually during performances.

A defining moment in her public history occurred in February 2018 when she appeared in Pikotaro's viral music video "Vegetable." The clip featured Tamai playfully slapping the singer's buttocks, an act that garnered international attention and introduced her to audiences beyond the J-pop sphere. This incident remains one of the most cited anecdotes regarding her career.

Tamai also holds the distinction of being one of the few original members of Momoiro Clover Z to remain active for nearly two decades. Her ability to evolve from a child star to a respected adult performer in the industry is often highlighted as a testament to her resilience and adaptability in a fast-changing entertainment landscape.

This figure reflects her earnings as a long-standing member of Momoiro Clover Z, combined with income from her solo voice acting roles, variety show appearances, and endorsement deals.
