Love ForeverKatō Miriya × Shimizu Shōta

If there’s a heart-stirring classic where the wish for eternity intersects with the sorrow of parting, it has to be this song! Released in May 2009, it’s a collaboration single by Miliyah Kato and Shota Shimizu, also included on the album “Ring.” Set to an R&B-based melody, the call-and-response sung from both a man’s and a woman’s perspective is especially striking.
The lyrics, which express gratitude for having met and the preciousness of the shining time they spent together, warm your heart every time you listen.
Spurred by this hit, the golden duo known as “MiliSho” was established, leading to the creation of many classics.
It’s a perfect recommendation not only for those who wish to stay with their lover forever, but also for those who want to beautifully etch a past romance in their hearts—and it’s an ideal track to fire up a karaoke duet.
The Day After EternityAdo

Known for her powerful rock numbers, Ado delivers a ballad that weaves love with a delicate voice.
Written and composed by Vocaloid producer Teniwoha, this track was released for White Day in March 2022 and is also included on the album “Zanmu.” The structure, repeating the phrase “I love you” twenty-five times in the lyrics, feels like a profound prayer that words alone can’t convey, deeply moving listeners.
Created by the same team behind the previous year’s “Gira Gira,” it can also be enjoyed as a continuation of that story.
Recommended for those who want to touch a bittersweet yet beautiful love, as if thinking of someone precious they can never meet again.
Listen on a quiet night while thinking of someone with all your heart.
Merry XmasBoA

This is a classic winter ballad sung by BoA, who serves as a bridge between Japan and South Korea and continues to captivate fans with her overwhelming vocal power.
It portrays eternal love—the wish to always be together with the one you love—as white snow piles up, and just listening gently warms the heart.
Released in December 2004 as her 15th single, the song was featured in a commercial for Toshiba’s mobile phone “W21T,” and it remains a beloved winter staple to this day.
It’s said to be a song especially dear to BoA herself, with an episode where she was moved to tears during a live performance.
