Started working as a music writer as a side job while employed at a record shop, and for over 18 years I’ve contributed to music magazines, disc guide books, mooks, and web media. As a writer my main field is Western music, but as a listener for over 35 years, I always try to keep my curiosity alive with the motto “I like what I like.” I have experience playing in bands, where I was a bassist who handled songwriting and composition. Instruments I’ve played include bass, guitar, and piano. I began studying English in my mid-40s and continue to do so today.

If you’re someone who blows off steam with karaoke, you’re probably also attending Christmas events and year-end parties.

This article rounds up songs perfect for 30-somethings to sing at karaoke during Christmas.

It’s included on a single set for release in February 2025 and has also been chosen as a TV program theme.

When it was first performed at the Nippon Budokan in November 2024, the Christmas party–themed production reportedly brought the house down.

It’s the perfect track for when you want to enjoy time with friends or when you need a boost of energy.

The feelings for a loved one, expressed through a warm voice and melody, truly touch the heart.

Released by Dai Hirai in December 2024, this song is perfect for a special Christmas night.

It vividly portrays the sound of bells echoing through the city, couples walking the streets, and the loneliness of spending the night alone.

But it’s not merely a sad song—by the end, it gives you the strength to look forward with a positive spirit.

This piece might just save your heart.

Singer-songwriter AI captivates fans with songs that blend Black music into J-pop and a soulful voice that brings out that musicality to the fullest.

“Happy Christmas,” included as a bonus track on her two-disc 11th album Wa to Yo, was chosen as the theme song for AEON’s Hello! New CHRISTMAS campaign.

The arrangement, which kicks off with powerful vocals, is guaranteed to instantly elevate the energy at karaoke, too.

Just as the title suggests, it’s an upbeat tune that sets the stage for a happy Christmas.

AI – Happiness

HappinessAI

Released in 2011, this is the song that became a hot topic as a Coca-Cola commercial track! I’m sure many people listened to it a lot back then.

From the intro, the distinctly Christmas-like sound is striking! It’s mid-tempo with a strong beat, so while it’s laid-back, it definitely gets you grooving.

With rap-style sections and soulful, sustained high notes, the difficulty is a bit on the higher side, but it’s a song I hope you’ll sing without overthinking it and just have fun.
