An ambitious work by Tani Yuuki, featuring an impressive sound that weaves in light Irish musical elements and a soaring vocal that resonates with the heart.

Released in May 2025, this gem of a track preceded the album “Kōkaishi” (Navigator).

Its delicate lyrics—probing the meaning of encounters and expressing a strong resolve to overcome hardships and build a future with someone dear—leave a lasting impression.

The song has a fresh feel that evokes setting sail on the vast ocean of the future.

The album “Kōkaishi” is slated for release on June 18, and a free live show at Yokohama Red Brick Warehouse is planned for this summer.

It’s a song I sincerely want those who aim to keep moving forward, and those whose feelings for someone special are growing, to hear.

Set to a heartrending melody, feelings of farewell are sung.

Released in 2018 as a song by Kanzaki Iori and later included on the album “Hakushi,” it poignantly voices regret over a past romance and emotions for days that can never return.

The piano-centered arrangement unfolds dramatically toward the latter half, making it feel as though every note carries emotion.

It’s a work that blends gentleness with sorrow—one I’d like those suffering from the pain of parting to hear.

A ballad that embraces loneliness and solitude was released by Rokudenashi in February 2025.

While containing hardship and pain, it carefully portrays an earnest desire to cherish a loved one and find hope.

With MIMI’s delicate melodies and Ninjin’s expressively rich vocals, this work stays by your side on lonely nights and helps you take a step toward tomorrow.

When you feel isolated or carry pain in your heart, listening to this song will gently cradle your unsteady feelings.

The City of Love, SapporoIshihara Yūjirō

This gem of a love song, which tells a romance beginning at Sapporo’s iconic Clock Tower, is cherished by many as one of Yujiro Ishihara’s signature numbers.

Released as a single in May 1972, it drew attention as a groundbreaking work told from a woman’s perspective and went on to sell a total of 650,000 copies.

Coinciding with the Sapporo Winter Olympics held that year, the song also helped convey Sapporo’s allure to listeners across Japan.

Wrapped in Ishihara’s deep, gentle vocals, the feelings of a woman who discovered love beneath a tender sky are tenderly sung, evoking vivid scenes in which memories of love deepen with the changing seasons.

A duet version with Miyuki Kawanaka was later produced, and this piece remains a beloved classic that beautifully weaves together Sapporo’s scenery and the memories of love—an unforgettable song that lingers in the heart.

Alexandros is a rock band that has been active since the 2000s.

Since entering the 2020s, they’ve further refined their stylistic breadth, releasing hits that differ in taste each time.

Among their songs, the one I particularly recommend is “Coffee Float (feat.

hard life).” It’s a work that feels like a mix of indie rock and artcore, featuring fast-paced percussion, while the vocal line is relatively monotone and emphasizes the lower register.

It’s exceptionally easy to sing and highlights a deeper voice, so consider adding it to your repertoire.

PSYCHIC FEVER – Cold Rain (Official Visualizer)
Cold RainPSYCHIC FEVER

A drama tie-in song by PSYCHIC FEVER that cultivates a dark, beautiful, and mysterious mood over a sophisticated, disco-tinged backing track.

Released in November 2024 as the opening theme for the Yomiuri TV/Nippon TV Thursday drama “OCTO: Emotion Investigator Akari Kokono Season 2,” the track deftly expresses the “colors” of complex human psychology and emotion.

The group’s global musicality is fully on display here, captivating listeners with expressiveness that transcends borders and language barriers.

With a dynamic rhythm that seems to blow away the gloom of the rainy season and vocals that delicately weave the nuances of emotion, it’s a standout song that’s perfect as BGM for a rainy-day drive.
