🩸 About the Track

“hourglass” is a dreamy and emotional piece of alternative j-pop that blends ambient japanese music, quiet heartbreak, and a cinematic j-pop female vocal aesthetic into one fading soundscape. The track floats between nostalgic cityscape imagery and inner universe emotions, framing a world where time collapses into fragments. Through the lens of Suno AI-driven creation and noctia’s poetic tone, the sound becomes a soft ritual — a peaceful japanese pop piano memory dissolving into digital dust. This piece reflects the modern japanese soundscape emerging across Asia, linking AI Sound Design, independent japanese music scene, and a new wave of dreamy japanese pop.


🕯️ Concept & Symbolism

At its core, the song explores fading emotions, fragile hope, and the quiet bravery required to hold broken time in one’s hands. The hourglass symbolizes youth memory slipping through a crack, an emotional vulnerability shaped by the silence between two people. Each verse shifts like a memory fragment, aligning with the themes of midnight confession, tearful horizon, and the quiet recovery after a love that can no longer return. The song’s emotional resonance is enhanced through its imagery of blurred lines, vanishing footprints, and still-fading echoes.


🔮 Hook Words Analysis

This section highlights three symbolic words chosen from the lyrics — each representing a key to the song’s emotional and thematic core.

  • fragment: In “hourglass”, the word “fragment” symbolizes memory shards left behind in the emotional space between two people. It suggests that even incomplete moments can echo with powerful meaning.
  • blur: In “hourglass”, the word “blur” symbolizes the unstable boundary between past and present, reflecting how fading emotions distort one’s inner voice and emotional resonance.
  • voice: In “hourglass”, the word “voice” symbolizes the lingering presence of a person who is already gone, acting as a philosophical reminder that sound often survives longer than feeling. It becomes the spiritual pivot of the entire emotional landscape.

Together, these words form the inner axis of sound, emotion, and spirit — aligning with the Japanese concept of kotodama.


🎙️ Lyrics (Original Japanese)


[Intro (band ambient) slow swell]

[Verse 1]

揺れながら灯り滲むまま眠って
消えかけの声がまだ胸奥で fragment
淡い息が少しだけ揺らいで触れて
折れたラインをなぞる心の blur

[Pre-Chorus 1]

崩れた砂の音が静かで
君の姿だけが残って
触れたら壊れそうな future
消えた足跡は still fading

[Chorus 1]

ねえ、壊れた砂時計を抱いて
すれ違う時ばかり追っていた
君の残像が cry through me
冷たい夜を裂く voice, voice
もう戻れない記憶だけ抱いたまま

[Verse 2]

夜風に溶ける街の灯が揺れて
かすかな音だけが胸奥で fragment
浅い息がどこか遠く響いて消えて
滲むラインの上で震える blur

[Pre-Chorus 2]

流れた砂の音が静かで
君の気配だけが残って
触れれば逸れていく future
ゆれた足跡は still fading

[Chorus 2]

ほら、倒れた hourglass を抱いて
溢れた秒(とき)の意味を探してる
君の残光が cry through me
静かな闇に響く voice, voice
ただ届かない願いだけ抱いたまま

[Bridge]

夜明け前の空気が少し痛くて
触れられない距離だけ増えていく
君の名前をそっと呼んでみても
時間だけがゆっくり零れていくんだ

[Chorus 1 — Reprise]

ねえ、壊れた砂時計を抱いて
すれ違う時ばかり追っていた
君の残像が cry through me
冷たい夜を裂く voice, voice
もう戻れない記憶だけ抱いたまま

[Outro (band ambient fade)]
