Kumiko Ōsugi’s Most Popular Songs Ranking [2026] (1–10)
Doraemon SongŌsugi Kumiko1rank/position

This is the opening theme, released in 1979, for Doraemon, a work featuring the cat-shaped robot from the future who springs into action, based on the manga by Fujiko F.
Fujio.
The series itself is often described as a national anime, and this song, Doraemon no Uta, is remembered alongside the series as a representative Japanese anime song that symbolizes the work.
The lyrics portray what kind of being Doraemon is, and another distinctive feature is the choice of simple words that are easy to understand for any age group.
Aim for the Ace!Ōsugi Kumiko2rank/position

Aiming for the Ace! is Suzue Miuchi Yamamoto’s sports manga, serialized in Weekly Margaret from 1973, famous for sparking a tennis boom.
The story follows a protagonist who joins the tennis club out of admiration, suffers bullying after being chosen as the club’s representative, and overcomes those hardships to grow into a top-tier player.
That narrative can also be felt in the opening theme song.
Set to a bright-sounding arrangement, the track seems to express the determination of a player who fights in solitude.
dawn roadŌsugi Kumiko3rank/position

Based on the children’s novel written in the 19th century by the British female author Ouida, “A Dog of Flanders” was produced in Japan as an animated work in 1975.
It has been passed down as a story about the friendship between a poor boy, Nello, and the old dog, Patrasche, culminating in a sad ending centered on painting.
Despite this, the opening theme song carries no sense of grimness; as its title suggests, it evokes the bright atmosphere of dawn and even conjures an image of joyful dancing.
Together with Don ChuckŌsugi Kumiko4rank/position
The charming theme song born from a beloved 1970s anime is full of appeal that captivates children’s hearts.
Its lively melody and cheerful calls joyfully portray the wonderful friendships among the forest animals.
Kumiko Ōsugi’s clear, transparent voice gently sings of the protagonist’s sense of adventure and bonds with friends.
Released by Canyon Records in June 1975, it was also included on the album “Time of Radiance: Songs of Kindness.” The song was cherished as the opening theme for the anime of the same name, which aired from April to September 1975.
It’s a bright, uplifting tune you can enjoy humming along to and moving your body with together with your children.
Song of Jungle KurobeeŌsugi Kumiko5rank/position

Jungle Kurobee is a manga by Fujiko F.
Fujio that was adapted into a TV anime in 1973.
Both the original manga and the anime were long unavailable, but they can now be obtained.
The opening theme is Jungle Kurobee no Uta, sung by Kumiko Osugi, and the video is a cover by Hatsune Miku.
Doraemon LullabyŌsugi Kumiko6rank/position
A lullaby from Doraemon, one of Japan’s most beloved and iconic characters.
It was released on October 1, 1990, and is sung by Kumiko Osugi.
When you have a slightly scary dream or can’t fall asleep, listening to it makes you feel as if Doraemon is there to comfort you.
Toothbrushing SongŌsugi Kumiko7rank/position

There have always been songs about brushing your teeth, no matter the era, haven’t there? This particular track used to play on the Asahi Broadcasting radio show “Ohayō Personality Yozo Michikami desu.” Hearing a toothbrushing song on a morning radio program really puts you in a crisp, refreshed mood, doesn’t it? It’s said to have aired in the early 1980s (the first half of the Showa 50s), and it’s the quintessential Showa-era children’s song—but maybe that very quality will sound fresh to kids today! It’s the perfect tune for when you wake up, before heading out, or whenever you want to reset your mindset.
I am mysteriousŌsugi Kumiko8rank/position

This song, whose bittersweet yet warm melody resonates in the heart as if painting the sunset before your eyes, is the ending theme of the 1986 film Doraemon: Nobita and the Steel Troops.
For many listeners, it surely brings back memories of the film’s moving climax.
The lyrics by Tetsuya Takeda portray the protagonist’s emotional growth and delicate, shifting feelings, beautifully expressed through Kumiko Osugi’s clear, translucent voice.
This classic was released in February 1986, ahead of the film’s premiere, and has since become a staple featured on albums such as The Complete Collection of Songs from the Doraemon Movies.
It’s the perfect track for savoring the lingering resonance of the story while reminiscing about childhood.
Attack No. 1Ōsugi Kumiko9rank/position

This commercial, which aired in 2019, is a parody piece using footage from the anime “Attack No.
1.” It even features a rewritten version of the theme song as the BGM, with lyrics that highlight the plan’s appeal.
It’s a memorable commercial that catches the eye not only of those familiar with the original work but also of younger viewers who aren’t.
To Rock RiverŌsugi Kumiko10rank/position

This refreshing number, sung by Kumiko Osugi, is marked by banjo tones that evoke the start of an adventure.
It was chosen as the opening theme for the TV anime Rascal the Raccoon, which began airing in 1977.
Many of you may recall the scene where Rascal and the boy ride a canoe down the river.
The lively rhythm and her clear vocals heighten the sense of anticipation for what’s to come.
Be sure to check it out as BGM to brighten the big moments of adorable children.
