Onyanko Club (おニャン子クラブ, Onyanko Kurabu, meaning "Kitty Club") was a leading Japanese female pop idol ensemble during the 1980s. Several members branched out to form subgroups such as Nyangilas, Ushiroyubi Sasaregumi, and Ushirogami Hikaretai, whose tracks were featured as theme songs for well-known 1980s anime like High School! Kimengumi and Tsuide ni Tonchinkan. The group also launched the careers of prominent idols including Shizuka Kudo. Produced by Hiroshi Ishida and Kazuji Kasai—both linked to Fuji TV's Yūyake Nyan Nyan—Onyanko Club played a pivotal role in the development of Japan’s idol culture.
1985
On 1 April 1985, Onyanko Club made their debut on Fuji TV’s weekday variety program airing from 5 to 6 p.m. The original lineup consisted of nine high school students plus two alumni, Sayuri Kokusho (No. 8) and Satomi Fukunaga (No. 11), who were chosen through special episodes of Fuji TV's late-night show All Night Fuji. These episodes acted as pilots for Yūyake Nyan Nyan. Auditions held during the show spanned five days, where candidates vied for membership in Onyanko Club; aside from the founding eleven and those selected via the 1986 Miss Seventeen Contest, most members joined through this audition process.
Beginning 15 April 1985, host Tsurutarō Kataoka engaged in on-air provocations directed at wrestler Dump Matsumoto, famed for her villainous image. On 19 April, Matsumoto unexpectedly appeared in the studio carrying a Shinai, prompting Kataoka to flee and issue repeated apologies. This incident notably affected Onyanko Club members Sayuri Kokushō, Mika Nagoya (Nyangilas), Satomi Fukunaga, and Sonoko Kawai, creating a memorable highlight for the program.
Smoking scandal
Within three weeks of the show's premiere, six members were caught by Shūkan Bunshun smoking at a kissaten near Fuji TV’s former Shinjuku headquarters. These members stopped appearing on the program starting 18 April. Five were quietly dismissed by 25 April due to underage smoking; one member was not implicated.
The group’s inaugural single, Sailor Fuku o Nugasanai de, was introduced on Yūyake Nyan Nyan on 3 June. Vocal leads included Eri Nitta (No. 4), Miharu Nakajima (No. 5), Satomi Fukunaga, and Kazuko Utsumi (No. 13). Released by Canyon Records on 5 July, it initially ranked number 34 on Oricon’s singles chart and climbed to number five by its sixth week. A planned release event with handshake sessions in Ikebukuro was canceled after attendance unexpectedly surpassed 4,000 people, raising safety concerns.
In July, Sonoko Kawai (No. 12) appeared in Fuji TV’s live-action drama Sukeban Deka, with her debut solo single slated for September release. Her song Namida no Jasmine LOVE along with its B-side premiered on Yūyake Nyan Nyan in August, featuring backing vocals from four other Onyanko Club members. That same month, an audition was held to select a new member for a Sukeban Deka sequel; Akie Yoshizawa won and was assigned No. 25. On 31 August, Kawai’s solo release event titled "Nyan Touch Love Party" took place at Yomiuri Land EAST.
Kawai’s first solo single, distributed by CBS/Sony Records on 1 September, debuted at number five and maintained the top spot for two consecutive weeks. Onyanko Club launched their debut studio album Kick Off via Canyon Records on 21 September; it was produced by Hiroshi Watanabe with compositions from Jun Sato, Ken Takahashi, among others; all lyrics were penned by Yasushi Akimoto. The album reached second place on Oricon’s album chart and remained within the top 100 for thirty weeks. On 30 September, the subgroup Ushiroyubi Sasaregumi made their television debut with members Mamiko Takai and Yukiko Iwai (No. 19).
The official fan club "Konyanko Club," operated by Fujipacific Music, began on 1 October and grew to approximately 190,000 members at its peak. Onyanko Club held their inaugural concert titled "Kick Off" at Hibiya Open-Air Concert Hall on 5 October; this performance was recorded and released by Pony Inc. Concurrently, Ushiroyubi Sasaregumi released their first single through Canyon Records; both tracks served as themes for Fuji TV’s anime High School! Kimengumi. Producer Kazuji Kasai renamed the subgroup from "Kiwi-Gumi" to Ushiroyubi Sasaregumi to better match lyrics written by Akimoto. Their single reached number five on the charts. Onyanko Club’s second single, Oyoshi ni Natte ne Teacher, released on 21 October, debuted at number two.
Yoshizawa released her debut solo single Naze? no Arashi under For Life Records as "Yoshizawa Akie with Onyanko Club" on 1 November. Backing vocals were credited to four members—Aki Kihara (No. 6), Mika Nagoya, Harumi Tomikawa (No. 14), and Ruriko Nagata (No. 18)—who also participated in promotional activities despite not contributing vocals to the recording. The track served as the ending theme for Fuji TV’s live-action series Sukeban Deka II, starring Yoshizawa herself. The single peaked at number eight.
In November, a joint audition with Nippon Broadcasting System's radio program Miyake Yuuji no Yangu Paradaisu selected campaign girls; winner Mutsumi Yokota became No. 28 while runners-up Minayo Watanabe, Chiaki Mikami, and Yuko Yajima joined as Nos. 29–31 respectively. Broadcast schedules were limited due to volleyball tournaments.
Toward the end of 1985, Kawai furthered her solo career with her second single Ochiba no Crescendo, released on 21 November, followed by her debut solo album Sonoko on 5 December via CBS/Sony Records. She also starred in Fuji TV’s drama The Mirror of Janus, aired from December through April 1986, and held her first solo concert at Shinagawa’s Gold Hall on 28 December; this concert was later issued on video by CBS/Sony Home Video in March 1986.
1986
Eri Nitta, designated as Onyanko Club member number 4, launched her solo debut single "Fuyu no Operagrasu" in January 1986 through Canyon Records after its initial broadcast on Yūyake Nyan Nyan in December 1985. The single immediately claimed the top spot on the charts, maintaining number one for four consecutive weeks and surpassing sales of earlier Onyanko Club singles. On 21 January, Ushiroyubi Sasaregumi's second release "Banana no Namida" also debuted at number one and was selected as the ending theme for Fuji TV's anime High School! Kimengumi. That same month, Sayuri Kokusho, Onyanko Club member number 8, introduced her first solo single "Valentine Kiss," featuring backing vocals from members Mako Shiraishi (number 22) and Minayo Watanabe. Issued by CBS/Sony Records under the name "Kokusho Sayuri with Onyanko Club," it entered the charts at number two.
In February, Yūyake Nyan Nyan announced that Miharu Nakajima and Sonoko Kawai would graduate from the group in April. Nakajima intended to leave the entertainment industry to study dental hygiene, whereas Kawai planned to embark on a solo music career. The group coined the term "sotsugyou (卒業)"—meaning "graduation"—to describe member departures, aligning with their concept of functioning as a student club balancing education and entertainment. Members were obligated to attend high school and maintain satisfactory academic performance; failure to comply resulted in dismissal or restrictions on activities. For instance, Mutsumi Yokota and Harumi Tomikawa experienced limited television appearances due to school commitments.
On 21 February, Onyanko Club released their third single "Jā ne" via Canyon Records as a farewell tribute to Nakajima. Although initially intended as Nakajima’s solo debut, she requested it be credited to the entire group. The single debuted at number one. Subsequently, on 1 March, Akie Yoshizawa’s second single "Kisetsu Hazure no Koi" topped the charts for two weeks; its B-side "Kaiin Bangou no Uta," performed by all remaining 22 members, featured individual verses introducing each member. On 10 March, Onyanko Club’s second album Yume Catalogue reached number one on the Oricon album chart, marking the first time several members had solo vocal parts.
The group's inaugural nationwide concert tour commenced on 16 March at Hokkaido Kosei Nenkin Kaikan in Sapporo, encompassing 14 performances across major cities and attracting a total audience of 96,673. Tickets were exclusively available to fan club members. On 21 March, Kawai’s third single "Aoi Stashion" secured the top chart position for two weeks and became the most successful single among all group releases during their active years. A graduation ceremony for Nakajima and Kawai was broadcast on 31 March, coinciding with two concerts at Nippon Budokan as part of the tour. Their final appearances as group members occurred on 1 April during three Budokan shows; these concerts were recorded and aired on Fuji TV.
Also on 1 April, the subgroup Nyangilas—composed of Aki Kihara, Mika Nagoya, Rika Tatsumi, and Mako Shiraishi—issued their debut single "Watashi wa Rika-chan" through Warner-Pioneer. Initially debated on Yūyake Nyan Nyan, this subgroup leveraged their comedic appeal despite limited popularity. Released on April Fools’ Day, the single debuted at number one, outperforming boy band Shonentai’s anticipated release from the same label.
Eri Nitta's second single "Koi no Rope wo Hodokanaide," released by Canyon Records on 10 April following revisions she requested, held the number one spot for two weeks. Onyanko Club’s fourth single "Otto Chikan!" followed on 21 April featuring lead vocals by Satomi Fukunaga, Kazuko Utsumi, Sanae Jounouchi, Ruriko Nagata, and Mutsumi Yokota; it also reached number one.
Fuji TV introduced a weekly variety program titled Yūshoku Nyan Nyan starring Onyanko Club starting 2 May to promote boy band Musukko Club; however, it concluded by September. That month witnessed chart-topping releases from Ushiroyubi Sasaregumi’s third single "Zousan no Sukyantee" and Kokusho’s sophomore solo effort "Natsu wo Matenai."
On 21 May, Satomi Fukunaga released her first solo single "Kaze no Invitation" via Canyon Records after premiering it during the March tour. The launch event drew approximately 6,500 fans with extensive overnight queues. The single debuted at number one.
Sanae Jounouchi's debut enka-style single "Ajisai Bashi," released by CBS/Sony Records on 11 June, debuted atop the charts—marking an unprecedented achievement for an enka debut in Oricon history that remains unmatched as of 2023.
Nyangilas followed with their second single "Jibun de Yuunomo Nandesukeredo," released on 21 June and also debuting at number one. Mamiko Takai’s solo debut "Cinderella-tachi e no Dengon," issued on 25 June while still part of Ushiroyubi Sasaregumi, similarly topped the charts.
In July, Minayo Watanabe premiered her first solo single "Hitomi ni Yakusoku" on Yūyake Nyan Nyan; a release event held at Nippon Budokan attracted roughly 12,000 attendees. Onyanko Club’s third album Panic the World, a double album combining new tracks with a greatest hits compilation from various labels, was released on 10 July and reached number three on Oricon charts. Watanabe’s single debuted at number one upon its official release on 16 July.
The group’s second nationwide concert tour titled "Onyanko Panic" began on 19 July at Yokohama Stadium where five members—Eri Nitta, Mika Nagoya, Satomi Fukunaga, Akie Yoshizawa, and Kumiko Susan Yamamoto (number 32)—were announced to graduate in September; four planned solo careers while Yamamoto intended to retire to focus on college studies. Additional stadium concerts took place in Nishinomiya on 21–22 July before continuing through multiple cities until September. On 21 July, Onyanko Club’s fifth single "Osaki ni Shitsurei," featuring lead vocals by Harumi Tomikawa, Yukiko Iwai, Tomoko Fukawa (number 33), and Marina Watanabe (number 36), debuted at number one.
The film Onyanko the Movie: Kiki Ippatsu!, directed by Masato Harada and starring all group members, premiered nationwide via Toho Pictures on 23 August as a double feature alongside a comedy duo Tunnels' film. It included concert footage from Yokohama Stadium along with rehearsal and behind-the-scenes content.
In August, teen magazine Seventeen hosted its annual idol/model audition titled "1986 Miss Seventeen with Onyanko." Winner Noriko Kaise joined as member number 41; runners-up Makiko Saito, Toshie Moriya, and Naoko Takada became members numbers 42 through 44 respectively; all appeared on television for their debuts in late September.
Satomi Fukunaga’s second solo single "Heart no Ignition," used as an ending theme for Fuji TV’s live-action series Sukeban Deka III, premiered in September and was released by Canyon Records in October where it peaked at number two.
A graduation ceremony aired on 26 September for Nitta, Nagoya, Fukunaga, Yoshizawa, and Yamamoto coinciding with Nippon Budokan concerts marking their final performances within Onyanko Club; Nyangilas disbanded following Nagoya’s exit. The concert was later broadcast on Fuji TV and issued as a DVD in October 2003.
In September also marked formation of Onyanko Club B-Gumi—a junior high school subgroup consisting of runners-up from August auditions plus Mayumi Yamazaki (B-Gumi number 5), winner of a weekly audition segment; they made their television debut later that month.
Marina Watanabe’s debut solo release "Shinkokyu-shite," featuring backing vocals from Shizuka Kudo (number 38) and Akiko Ikuina (number 40), was issued by Epic/Sony Records on 8 October under the name "Watanabe Marina with Onyanko Club." The single debuted atop Oricon charts; Watanabe established a record as the youngest female artist (15 years and eleven months) with a debut single reaching number one—a record held for over fourteen years.
Onyanko Club’s sixth single "Koi wa Kuesuchon," released by Canyon Records on 1 November with lead vocals from Yukiko Iwai, Ruriko Nagata, Mako Shiraishi, and Akiko Ikuina served as both opening and closing themes for Fuji TV’s anime Anmitsu Hime, which aired from October ’86 through September ’87; it reached number one.
Kazuko Utsumi’s first solo effort "Aoi Memories," associated with Fuji TV's anime Touch, was released by Canyon Records on 7 November debuting at number three. Utsumi had prior acting experience since childhood along with vocal training under Masaaki Hirao.
CBS/Sony issued compilation album Merry X'mas for You on 5 December featuring a newly recorded title track performed by Sonoko Kawai, Sayuri Kokusho, Sanae Jounouchi, Minayo Watanabe (CBS/Sony), Marina Watanabe (Epic/Sony), plus five previously released individual songs; it attained number three position on Oricon albums chart. Concurrently Akiko Ikuina appeared in Lawson convenience store advertisements promoting chicken nuggets using her song "Heart ni Bokin wo," which later became an Onyanko Club group song rather than her solo debut track.
Eri Nitta conducted her first solo concert tour titled "E-AREA," including a Nippon Budokan performance in December; an earlier show at Nakano Sun Plaza was recorded and released as video in January ’87. Sayuri Kokusho concluded her initial solo tour with a December concert at Ryogoku Kokugikan which was recorded for video release in April ’87.
A graduation ceremony aired on Christmas Eve honored Mami Yumioka (number 34), Takako Okamoto (number 35), and Maki Takabatake (number 39), who retired from entertainment after being excluded from recent promotional activities due to lack of confidence in pursuing solo careers.
By the end of the year, singles related to Onyanko Club dominated Oricon's Japanese singles chart for thirty-six out of fifty-two weeks in 1986—with thirty chart-topping releases connected to the group. Both group albums and solo albums by Eri Nitta and Sonoko Kawai secured multiple number-one positions across Oricon album rankings throughout the year.
1987
During the Yūyake Nyan Nyan broadcast on 5 January, it was revealed that five members—Aki Kihara, Sayuri Kokusho, Kazuko Utsumi, Rika Tatsumi, and Mamiko Takai—would officially "graduate" in April. Of these, Kokusho, Utsumi, and Takai embarked on solo careers, whereas Kihara and Tatsumi withdrew from the entertainment industry. Onyanko Club’s seventh single, "No More Ren'ai Gokko," featuring lead vocals by Harumi Tomikawa, Ruriko Nagata, Yukiko Iwai, and Mako Shiraishi, premiered on 9 January and secured the number one spot upon its release on 21 January under Canyon Records. Concurrently, Takai’s debut solo album Itoguchi, which compiled her previous singles, also topped the Oricon album chart.
On 21 February, Ushiroyubi Sasaregumi released their sixth and final single "Kashiko" through Canyon Records, marking their fifth consecutive chart-topping single. Both this track and its B-side served as theme songs for Fuji TV’s anime series High School! Kimengumi. The same day saw the release of Onyanko Club’s fourth studio album Side Line, which included solo performances from newer members such as Shizuka Kudo and Noriko Kaise. Shortly thereafter, on 26 February, Marina Watanabe’s first solo album MARINA was issued by Epic/Sony Records; both albums achieved number one rankings. A pre-release event held at Nippon Budokan attracted an audience of approximately 10,000.
On 11 March, Canyon Records released Ushiroyubi Sasaregumi’s compilation album ∞ (Unlimited), which topped the album charts and featured all six singles alongside previously unreleased tracks. Prior to Ushiroyubi Sasaregumi’s disbandment due to Takai’s exit, Takai’s fourth solo single "Kagerou" and Yukiko Iwai’s inaugural solo single "Tenshi no Bodyguard" were introduced on Yūyake Nyan Nyan on 9 March. That same day marked Rika Tatsumi’s solo debut with "Sonna Tsumorija Nakattanoni." Upon its release on 18 March, Takai's single reached number one on the charts; Tatsumi’s single peaked at number 34. A surprise "graduation ceremony" took place on 20 March for four Onyanko Club members along with two B-Gumi members; their departure reasons were not disclosed. Most of these individuals eventually left the entertainment field except for Mayumi Yamazaki, who released four solo singles between 1988 and 1992.
Iwai’s first solo single under the name "Yuuyu with Onyanko Club," supported by three fellow group members, was released on 25 March and debuted at number two. The group launched their third nationwide tour titled "Onyanko Sailing Yumekoujyou" starting on 28 March at Osaka-jo Hall, drawing an audience totaling roughly 200,000 across prominent venues.
A graduation ceremony featuring Kihara, Kokusho, Utsumi, Tatsumi, and Takai was broadcasted on 30 March. Their final performances as Onyanko Club members occurred on 4–5 April at Tokyo's Yoyogi National Gymnasium; recordings from these concerts were subsequently issued as video and live albums in May and June by Pony Inc., Canyon Records, Epic/Sony Records, and CBS/Sony Records.
On 6 April, Onyanko Club B-Gumi participants Mitsuko Yoshimi, Miyuki Sugiura, and Kumiko Miyano were promoted to full Onyanko Club membership as numbers 49 through 51 following their involvement in the third nationwide tour.
The third subgroup Ushirogami Hikaretai, comprising Shizuka Kudo, Akiko Ikuina, and Makiko Saito, debuted their first single "Toki no Kawa wo Koete" on 13 April as successors to Ushiroyubi Sasaregumi. Both this single and its B-side served as themes for Fuji TV's anime High School! Kimengumi. In April, Wakako Suzuki joined as member number 52 after winning a weekly audition—becoming the group's final addition. Onyanko Club released their eighth single "Katatsumuri Samba," led by Tomikawa, Kudo, Yoshimi, and Sugiura, premiering on 28 April; both this release and Ushirogami Hikaretai's debut (issued in May) reached number one.
On 15 June it was declared that Onyanko Club would disband following their last concert scheduled for September; concurrently Yūyake Nyan Nyan was set to conclude on 31 August. Marina Watanabe’s fourth single "Natsuyasumi Dakeno Side Seat" (released 15 July) alongside Minayo Watanabe’s fifth single "Amaryllis" (released 29 July) both attained top chart positions; Minayo distinguished herself as the only female artist to achieve five consecutive number-one singles since debut.
Yukiko Iwai’s debut solo album Yuuyu Kousen, launched on 29 July via Canyon Records, entered Oricon’s LP chart at number one. Onyanko Club's fifth and final studio album Circle, a double-disc project released on 5 August through Kirigirisu Records—a label jointly operated by Canyon Records, For Life Records, CBS/Sony Records, and EPIC/Sony Records—included new compositions from current members, soloists, former members who had graduated, as well as Ushirogami Hikaretai; it peaked at number two.
The fourth nationwide concert tour titled "Onyanko Club Kaisan Kinen Zenkoku Jyudan Final Concert" commenced on 1 August in Sapporo and continued through major cities until September. Graduated members made guest appearances at most events.
Ushirogami Hikaretai issued their second single "Anata wo Shiritai" on 12 August through Canyon Records; this track also served as a theme for High School! Kimengumi, debuting at number two. Onyanko Club's ninth single "Wedding Dress," led by Tomikawa and others, premiered on 10 August and was released by Kirigirisu Records on 21 August; it too debuted at number two.
After more than two years of broadcasting, Yūyake Nyan Nyan concluded with a special two-hour live episode on 31 August featuring most former members along with a graduation ceremony for the remaining nineteen members. On that same day Shizuka Kudo’s debut solo single "Kindan no Telepathy" was released by Canyon Records and achieved the number one position.
Onyanko Club wrapped up their activities with final concerts held at Yoyogi National Gymnasium on 19–20 September—two performances on the first day followed by three on the second—with eleven graduated members reuniting for joint performances. The afternoon show of the concluding day was broadcast live by Fuji TV; the evening performance was recorded and later issued as a video by Pony Canyon in October. By the time of disbandment, a total of forty-three out of seventy-one singles associated with them—including those from subunits—had reached number one on Oricon's Japanese singles chart.
Post-disbandment
After the group's dissolution, members who had previously released solo material, along with those from the subgroup Ushirogami Hikaretai, broadened their pursuits through new musical projects and media engagements. Several individuals introduced solo singles following the breakup: Onyanko Club’s member number 48, Kayo Agatsuma, launched "Private wa Dangerous" via CBS/Sony Records on 21 November 1987, which climbed to number nine on the charts. Member number 5, Mayumi Yamazaki, released "Hitomi wo Mitsumete" under Polydor Records on 1 April 1988. Akiko Ikuina of Ushirogami Hikaretai debuted with "Mugiwara de Dance" through Pony Canyon on 21 May 1988; this track served as both the opening and closing themes for Fuji TV’s anime Tsuide ni Tonchinkan and reached number eight in rankings. Subsequently, Makiko Saito issued "Yaritai Houdai" via Pony Canyon on 21 July 1988, attaining position 28.
Prominent figures such as Sayuri Kokusho, Minayo Watanabe, Marina Watanabe, and Akiko Ikuina maintained flourishing careers in acting, singing, and television throughout the late 1980s into the 1990s, continuing their involvement in entertainment as of 2023. Sanae Jounouchi pursued a consistent path as an enka vocalist. Notably, Akiko Ikuina transitioned into a political role when she was elected to the House of Councillors representing the Tokyo at-large district in July 2022.
Shizuka Kudo enjoyed significant chart success during the 1980s and 1990s. Rika Tatsumi graduated from Tokai University and took on a position as a sales representative at Pony Canyon, where she promoted artists including Kudo across Tokyo and Nagoya.
Following her retirement in 1990, Eri Nitta shifted focus toward writing and television personality work. Miharu Nakajima worked as a dental hygienist before marrying in 1997. Aki Kihara and Mika Nagoya moved abroad for educational and professional opportunities, settling respectively in the Netherlands and Hong Kong. Harumi Tomikawa transitioned into a water sports instructor role at JAL Private Resort Okuma in Okinawa after careers in modeling and television. Kumiko Susan Yamamoto graduated from Bunkyo Gakuin College and joined companies affiliated with JR Central. Makiko Saito married the CEO of Sujahta Meiraku Group in 1998.
Onyanko Club’s tenth single, titled "Shoumi Kigen," marked their first release in fifteen years and was issued by Pony Canyon on 20 November 2002. Fourteen members participated in this recording: Nitta, Kihara, Kokusho, Nagoya, Utsumi, Tomikawa, Tatsumi, Jounouchi, Iwai, Shiraishi, Yokota, Minayo Watanabe, Yamamoto, and Fukawa. This release followed robust sales of the five-disc DVD box set Onyanko Club Saishuu-ban: The Final Episode (April 2002). Additional former members took part in reunion appearances on television coinciding with the single’s launch. Since then, the group has occasionally reunited for brief performances, including a notable appearance on Hey! Hey! Hey! Music Champ in 2012.
To commemorate three decades since their formation, Pony Canyon unveiled an extensive 126-CD box set entitled Kessei Sanjyusshuunen Kinen CD-BOX Single Record Fukkoku Nyan Nyan on 18 March 2015. This collection encompasses all singles released by Onyanko Club, its three subunits, and sixteen individual members between July 1985 and September 1989 across various labels such as Canyon Records, CBS/Sony Records, Epic/Sony Records, For Life Records, and Warner-Pioneer. Each original seven-inch single was recreated as a twelve-centimeter CD featuring scaled-down cover artwork along with A-side/B-side tracks plus instrumental versions; some discs also include audio commentary from members. The limited pre-order edition contains a total of 251 songs alongside their instrumentals spread over 126 CDs. A limited quantity was made available for general purchase following the initial release.
