[2026 Edition] Karaoke Songs That Will Get the Crowd Going—Perfect for Women in Their 40s

Lion HeartSMAP

Lion Heart – SMAP

SMAP is a five-member idol group so popular they’re often called a national sensation, and they expanded their reach not only as a group but also as individual performers.

Their 32nd single, “Lion Heart,” used as the theme song for the TV drama Food Fight, became a huge hit, helped by the popularity of its B-side, “Orange.” Since it’s a male vocal song, it may be difficult for women to sing in the original key, but even for men the overall key is low, so singing it an octave higher will sound nice.

It’s a heartwarming number that just about anyone in their 40s is sure to know.

Ikimonogakari 'Arigatou' Music Video

Since the late 2000s, Ikimonogakari has boasted top-tier sales and popularity in the J-pop scene, enjoying exceptional name recognition across all ages.

Their songs span a wide variety of genres, yet the melodies—anchored by simple, classic chord progressions—are incredibly pleasant and universally appealing.

It’s impressive how they consistently release “good songs” that don’t alienate any listeners.

Released in 2010, “Arigatou” served as the theme song for the NHK morning drama Gegege no Nyobo and is one of Ikimonogakari’s signature tracks, highly popular at karaoke.

While the chorus reaches slightly higher notes, it stays within a range manageable in chest voice, and there aren’t any large interval jumps, making it very singable and a strong candidate for a high karaoke score.

Hidamari no Uta / Le Couple (OFFICIAL MUSIC VIDEO)

At the time of its release, the song “Hidamari no Uta” was a huge hit.

It became popular as an insert song for the equally successful TV drama “Under One Roof 2,” which quickly brought Le Couple’s name into the spotlight.

Many people in their 40s may remember it strongly in connection with the drama.

Though the song gently sings of a sad, unforgettable love, listening to it leaves your heart feeling softly warm.
