This song, whose lyrics capture a bursting smile, features a bright melody that resonates in the heart.
It’s performed on NHK’s popular program “Okaasan to Issho,” so it’s well known among children.
The harmony between Yuuichirou Hanada and Atsuko Ono is wonderful, and just listening to it gives you energy.
It carries the message that even when you feel sad, you’ll be okay if you think of your friends, so I believe it’s a song that can stay close to children’s hearts.
It’s perfect for recitals and events, and it’s also a song you can sing and dance to in everyday childcare settings!
Head over heels for the cosmosHanada Yuuichirou, Ono Atsuko9rank/position

This song, themed around space, features a memorable wordplay that lines up the names of planets children explore and the colors of the rainbow in order.
It was broadcast with vocals by Yuichiro Hanada and Atsuko Ono as the “Song of the Month” for April 2020 on NHK E-TV’s Okaasan to Issho.
Created by Yujin Kitagawa of Yuzu, the piece is designed to naturally nurture children’s interest in nature and the universe.
It encourages kids to explore the world with a spirit of adventure and enjoy it with rich imagination.
The track is included on the album “Saishin Best: Uchuu ni Muchuu,” and is characterized by an upbeat, bright tempo that’s perfect for parachute (para-balloon) performances.
With lyrics that spark children’s curiosity and simple, easy-to-remember choreography, it’s ideal for group performances at sports days and school recitals.
Help! Oyoyo ManHanada Yuuichirou, Ono Atsuko10rank/position

This is the song of Oyoyoman, who comes to the rescue when you’re in trouble! When your room is a mess after playing, or when you’re too tired to walk anymore, Oyoyoman shows up and—like magic!—helps you tidy up or gives you a burst of energy.
It’s a fun song with an Arabian-style melody that sticks in your ears.
Whether it’s tidying toys your child doesn’t want to clean up or going out for a long time, this song might help switch their mood.
It’s a tune we hope parents and kids will sing together at the top of their lungs.
One idea is for the parent to get into character as Oyoyoman!

One, two, three!Hanada Yuuichirou, Ono Atsuko11rank/position

This is the July 2019 song “One-Two-Three!” The composer is Osamu Sakata, who served as the 7th “Uta no Onii-san” on Okaasan to Issho, and the lyricist is his daughter, Megumi Sakata, who is also a children’s song singer—making it a parent–child collaboration.
It’s also a message song that serves as a cheer for children: capturing animals as they hop and leap, and encouraging everyone to do their best and jump together.
One step, two steps, three stepsOno Atsuko, Hanada Yuuichirou12rank/position

This is a bright and adorable song that makes you picture children setting off with lively steps.
The changing scenery with every step and the excitement of a walk are expressed in cheerful words, and singing it naturally brings smiles.
Performed by Atsuko Ono and Yuichiro Hanada, who released their first album as a duo in October 2017, this piece—passed down on NHK’s program “Okaasan to Issho”—is still loved by many children today.
Its comfortable rhythm of “one step, two steps” makes it perfect for group singing.
Try enjoying it at a performance for younger children—stomping together with teachers and friends, adding cute choreography, and singing with joy!
Let’s hang out!Yokoyama Daisuke / Ono Atsuko13rank/position

This was Atsuko Ono’s debut “Monthly Song” after she became the 21st Uta no Oneesan in April 2016.
It’s a song about greeting a friend and saying, “Let’s meet again anytime.” During that year’s Family Concert at NHK Hall in Tokyo, Takumi Mitani, the 20th Uta no Oneesan, appeared as a guest and performed this song together with her.
Stylish fruitYokoyama Daisuke / Ono Atsuko14rank/position

It’s a song that turns the question, “Why do fruits have their colors?” into music.
There are many reasons, but it seems fruits have their own motives—like wanting to be eaten deliciously or having their seeds carried.
It might be fun to imagine this while you eat.
