Yumi Uchiyama

Yumi Uchiyama is a Japanese voice actress from Tokyo, best known for bringing Ako Udagawa to life in the BanG Dream! franchise and Aoba Tsukishima in The iDOLM@STER series. She has voiced over 100 roles across anime, video games, and foreign film dubbing since her debut in 2009.

Her vocal range is one of her standout traits, she can shift from a bright, girlish pitch to a warmer, mature register in the same scene. Fans of BanG Dream! know her as the drummer of Roselia, a role she performs both in the recording booth and on stage at live concerts. Outside the franchise, she has taken on characters in Kandagawa Jet Girls, Princess Principal, and Matoi the Sacred Slayer, showing a versatility that keeps casting directors coming back.

As of 2026, Uchiyama remains active in the industry, continuing her long-running roles while taking on new dubbing and narration projects. She is represented by Office Osawa and maintains a modest but loyal fanbase that follows her work across multiple series.[edit]

Uchiyama grew up in Tokyo as an only child, spending much of her childhood glued to anime like Sailor Moon and Pokémon. She was fascinated by the fact that the same voice could inhabit completely different characters, and that realization planted the seed for her career. After graduating from a Tokyo high school, she enrolled at the Japan Narration Actor Institute, where she trained in voice acting, singing, and narration.

Her first professional gig came in 2009, a tiny background role in the anime Saki. It was barely a line, but it got her foot in the door. The real turning point came when she auditioned for Ako Udagawa in BanG Dream!. That audition landed her the part that would define her career.[edit]

Uchiyama's breakout role as Ako Udagawa in BanG Dream! arrived in 2011. The franchise grew into a multimedia powerhouse spanning anime seasons, films, and live concerts, and Uchiyama became a fixture as Roselia's drummer. She performs live with the band, something that sets her apart from many voice-only peers.

In 2014, she joined The iDOLM@STER franchise as Aoba Tsukishima, another long-running role that keeps her busy with game recordings and live events. She expanded into live-action tokusatsu with parts in Kamen Rider: Heisei Generations FOREVER and Kamen Rider Zi-O in 2018 and 2019. Her dubbing work has also grown steadily, she has lent her voice to English, Korean, and Chinese films for Japanese audiences.

Through the 2020s, she continued voicing in The iDOLM@STER: Starlit Season (2020), BanG Dream! Poppin'Dream! (2022), and the Million Live! anime (2023). As of 2025, she remains active in both franchise work and narration for NHK documentaries.[edit]

Uchiyama is known in the industry for her vocal versatility and her ability to switch between cute and mature characters effortlessly. In live performances, she favors elegant feminine outfits that match the BanG Dream! aesthetic. Japanese media portrays her as a dedicated professional who keeps her private life firmly separate from her work. Her Twitter presence is minimal and professional, mostly retweets of official announcements and occasional photos of food or scenery. Fans celebrate her birthday on October 30 with fan art and social media posts, but there is no official fandom name. She is respected for her longevity in the industry and her consistent live performance energy.[edit]

The audience surrounding Yumi Uchiyama operates without a formal, unified moniker, distinguishing her fanbase from those of voice actors who command specific named legions. Her supporters are generally organized under the umbrella of enthusiasts for her individual roles rather than the actress herself, with no documented official fan club bearing a unique title. This decentralized structure means that while there are dedicated communities for her work in *BanG Dream!* or *Mushoku Tensei*, there is no single collective identity like an "Army" or a branded movement that defines her personal following. The interaction between the public and the artist remains largely professional, centered on her social media presence where she shares minimal personal updates. In the broader landscape of global celebrity metrics, iFANN has conducted a comprehensive evaluation of her standing as of August 2026. The data indicates that Yumi Uchiyama is currently not ranked within the Global Top 1,000 list maintained by the engine. She does not hold a placement in any published Top-100 scope lists at this time, reflecting a status of being evaluated but unranked in the current hierarchy. While she maintains a significant footprint in the Japanese entertainment industry through roles such as Rudeus Greyrat and Ako Udagawa, her global fame score has not yet reached the threshold required for inclusion in the primary ranking tables. This absence of a numeric rank suggests that while her career is robust and her recent projects like *Sakamoto Days* have garnered attention, she has not yet achieved the specific volume of worldwide consumption signals necessary to secure a position on the global charts. The scale of her influence remains concentrated within her native market and specific anime demographics rather than spreading into the general international consciousness measured by the engine's broadest parameters.[edit]

Her stage name utilizes the kanji 夕実, translating to "evening fruit," a poetic selection she has never fully elucidated. Colleagues describe her as shy in public settings yet possessing high energy when performing on stage. She is a skilled live singer who performs regularly with the band Roselia at BanG Dream! concerts. A rare crossover achievement in her career involves voicing characters in both Kamen Rider and Super Sentai series. She identifies as a self-described fan of Sailor Moon, the series that originally inspired her career path. Her reputation for extreme privacy is well-established; she rarely posts beyond work announcements on social media, keeping her personal life firmly separate from her public image. Recently, the announcement of her marriage to fellow voice actor Yuusuke Kobayashi marked a significant personal milestone acknowledged by her fanbase. Additionally, she has been added to the cast of *Sakamoto Days* and *Eren the Southpaw*, with the latter scheduled for an April 2026 premiere. A special program celebrating the fifth anniversary of *Mushoku Tensei: Jobless Reincarnation* was also confirmed, featuring the main cast including Tomokazu Sugita.[edit]

Uchiyama was raised in Tokyo as an only child. She has not publicly shared the names or occupations of her parents, and no information about extended family is available. She lives alone and has not mentioned any pets. Her private nature extends to her home life, she rarely discusses her living situation or daily routines in interviews.[edit]

Uchiyama frequently works with Aimi, Ayane Sakura, and Rimi Nishimoto across the BanG Dream! and The iDOLM@STER franchises. She has also collaborated with Sae Ōtsuka, Haruka Kudō, and Megu Sakuragawa in multiple projects.[edit]

Her income comes primarily from voice acting for anime episodes (typically ¥15,000–¥50,000 per episode), video game recordings, live concert appearances, dubbing work, and narration for documentaries. She likely earns additional income from merchandise royalties tied to the BanG Dream! and The iDOLM@STER franchises. Without public financial disclosures, any estimate remains speculative.[edit]
