If we become loversFukushima Sayaka

In the season when winter illuminations color the city, a song brimming with warm feelings of love has arrived from Sayaka Fukushima.

Released in December 2025, this work is clearly positioned as a Christmas song.

The lyrics portray the emotions of constantly thinking about someone as the seasons change, and the wish to deliver dreams and hope like Santa.

The blossoming imaginings of what she’d like to do if they became lovers and the places she’d love to take them make it perfectly romantic for a holy night.

Hailing from Mito City in Ibaraki Prefecture and bringing a background in track and field and education, her straightforward, down-to-earth storytelling resonates deeply.

It’s a recommended track for those experiencing unrequited love or for moments when you want to reaffirm your feelings for someone special.

Love Dial 6700Fingā 5

With an intro that mimics the ring of a rotary telephone and a spirited call that grabs your attention, this is a signature song by Finger Five.

Written and composed by Yu Aku and Tadao Inoue, it’s a breezy dance number that blends R&B and rock ’n’ roll elements into Japanese pop.

The catchy phone-number motif, set on the eve of a graduation ceremony, leaves an unforgettable impact once you hear it.

Released in December 1973, the song topped the Oricon weekly chart for four consecutive weeks and became a massive hit with over 1.6 million copies sold.

The following year, it was also used as the theme song for the film “The Great Adventure of Finger Five.” The soulful groove created by the five Okinawan siblings, paired with the charming vocals of the youngest sister, Taeko, weaves a harmony that lifts the spirits across generations.

It’s a perfect pick for those who want a bright boost during the season of farewells.

It was the theme song for the TBS drama “Beautiful Life: The Days We Spent Together,” and the CD jacket photo was apparently shot from a wheelchair’s perspective to match the show’s content.

It’s a dramatic slow rock number where Inaba’s poignancy and power coexist.

The song’s overall vocal range is G3–B4, and since the highest notes appear frequently in the chorus, stamina is essential—so it’s recommended for those who are good with high notes.

As the song progresses, you may find it harder to lock onto the pitch bar, but if you keep your eyebrows raised and project your voice far with energetic delivery, it should start to click!

Symphony No. 2, Movement IIISergei Rachmaninov

Among the large-scale symphonies by the Russian Romantic composer Sergei Rachmaninoff, the third movement of his Symphony No.

2 is exceptionally beautiful.

Premiered in February 1908, this work became a landmark piece that helped him overcome past harsh criticism and regain his confidence as a composer.

The clarinet’s long-breathed melody seeps into the heart like an endless song, gently embraced by the warm sonorities of the strings.

Played during diploma presentations or recessional scenes, it can create a moving atmosphere befitting the children’s departure on their next journey.

Kohei Fukuda, who continues to captivate enka fans with the overwhelming vocal power and delicate ornamentation he honed through folk music, is back.

Set for release in January 2026, “Kokorozashi (Resolve)” is a grand piece that questions the way we live and the convictions we hold.

Tetsuya Gen’s wistful melody blends beautifully with Fukuda’s solid, resonant voice, leaving a deep impression on the listener.

It’s a powerful yet warm work, perfect for the start of a new year.

It’s a full-throttle, uptempo track packed with that signature Chotokkyu entertainment flair, and it gets the crowd hyped at live shows with lots of call-and-response parts everyone can shout together! The overall vocal range is two octaves, from C#3 to C#5, but thanks to the headbanging sections and the unique lyrics sprinkled with otaku terms and internet slang, you can hit those high notes pretty easily if you sing brightly and keep the energy up.

Don’t worry about pitch—just have fun singing, that’s the most important thing! By the way, I love Ryoga’s funny faces during the song and always burst out laughing, haha.

Definitely check out the video!
