Among Vocaloid songs, this one stands out for its exceptional sensuality and velvety vocals that send shivers down your spine.

With lip noises and lyrics that emphasize the tongue, it naturally draws in listeners of any gender.

It’s an exquisitely sexy track, perfect for setting a nighttime mood or indulging in a sultry atmosphere.

Go! Anpanmandoriimingu

Anpanman March has become so popular nationwide that it could practically be called a children’s song classic.

It’s a track we’d love dads with young kids to sing and dance to as well.

Since Anpanman is hugely popular with children, be sure to practice and give it a try.

Nintama RantarōHikaru GENJI

A nationally beloved anime that has been broadcast on NHK for many years.

While the theme song itself hasn’t changed, the artists who sing it have evolved with each generation.

It’s a long-running series passed down to the next generation.

In karaoke, too, it’s an ageless song handed down from parents to children, sung together across generations.

The grown-up Mr.

Osomatsu has also been adapted into an anime and is creating a buzz, and its original form is Osomatsu-kun.

The characters from Osomatsu-kun have many fans, and it’s such a popular anime that fan meetings are being held.

When you sing, I highly recommend doing it in cosplay.

Ashita no JoeBito Isao

A very serious boxing anime.

Each of the surrounding characters had a well-defined personality, so even now I can vividly recall them.

With its striking realism in the boxing scenes, it was an anime overwhelmingly popular among boys.

God Mars (Six Gods Combination) Ending Theme – Pyramid of Love / Kazuho Hiura

It’s God Mars, which anyone from the generation right in the heart of the combining-robot boom will recognize.

The characters are quite handsome, so I think it wouldn’t feel dated even if it aired today.

Combining mecha are always fascinating to watch, no matter when you see them.

Treasure of FlamesBOBBY

This is the song that was used as the theme for the still wildly popular animated film Lupin the Third: The Castle of Cagliostro.

It’s a cool, sophisticated track that’s sure to go over well not only in all-male settings but also with women listeners.

The film also drew attention for being directed by Hayao Miyazaki.
