Song Meaning: 雲になる - ヨルシカ

There are fewer than sixty words in “Kumo ni Naru.” The entire lyric sheet fits on a napkin. And yet the song runs over four minutes, carried by a rhythm that doesn’t quite sit still — a 7/8 time signature that keeps slipping into 6/8, like clouds drifting in and out of formation. n-buna, the composer behind Yorushika, described the song’s construction to Apple Music as an experiment in colliding worlds: jazzy chords with an overcast quality, the African hand drum djembe, post-rock’s love of odd meters, and — layered on top of all that — a J-Pop melody built on the natural rhythm of Japanese syllables. The result sounds like a song that’s hovering slightly above the ground, unable or unwilling to land.

Then there’s the voice. suis, Yorushika’s vocalist, recorded the guide vocal for “Kumo ni Naru” while she had a cold. The roughness in her singing was never supposed to stay — but n-buna heard something in the imperfection, a rawness that matched the song’s hazy, heat-shimmer atmosphere. They kept it. The final release is that demo vocal: unhurried, slightly weathered, drifting through the horn parts that bloom and dissolve in the distance like, well, clouds.

Yorushika is the project of composer n-buna and vocalist suis, a duo who have never shown their faces publicly. Formed in 2017 out of n-buna’s Vocaloid producer career and suis’s striking vocal clarity — described by critics as having a quality of transparency, like light through glass — they built their name on concept albums where every song serves a larger literary narrative. Their biggest international moment came with “Haru” (晴る), the opening theme for the anime Frieren: Beyond Journey’s End in 2024, but domestically they’d already become one of J-Pop’s most critically respected acts, with “Tada Kimi ni Hare” (ただ君に晴れ) surpassing 300 million streams. n-buna writes all lyrics, composes, arranges, and records the lead guitar parts himself. He has described the project’s philosophy in a single line: the creator should never stand in front of the work.

“Kumo ni Naru” sits as the second track on Nininshou (二人称 / Second Person), Yorushika’s fifth full album, released on March 4, 2026. The album is inseparable from a companion work: a “letter-form novel” — also titled Nininshou — published by Kodansha one week earlier. The novel consists of thirty-two physical envelopes containing roughly 170 handwritten letters between a boy who writes poetry and a literary mentor he calls “Sensei.” The album’s songs function as musical settings of the boy’s poems. “Kumo ni Naru,” then, isn’t simply a Yorushika track — it’s a young poet’s early attempt to give shape to longing, set to music by n-buna and breathed into being by a singer who happened to have a cold.

The Ridgeway Between Rice Paddies

The song opens with an act of stillness:

雲を見ていた昼の入道雲
Kumo wo miteita hiru no nyuudougumo
I was watching the clouds — the towering thunderheads of midday

私とあなた畦の夏道
Watashi to anata aze no natsumichi
You and I, on the summer path between the rice paddies

Two people. A summer afternoon. And above them, 入道雲 (nyuudougumo) — those massive, vertically stacked cumulonimbus formations that define the Japanese summer sky. The word itself is wonderfully physical: 入道 originally referred to a person entering Buddhist priesthood (and by folk extension, a towering bald-headed giant), so 入道雲 carries the image of a cloud so enormous it looks like a colossal figure rearing up into the heavens. This is not a wisp. This is a monument.

The ground-level image is just as specific. 畦 (aze) is not a road, not a sidewalk, not a trail. It’s the narrow raised ridge that separates flooded rice paddies — the kind of path where two people walk in single file, close enough to touch, surrounded on both sides by shallow water reflecting the sky. n-buna could have written 道 (michi) for “path” and kept the meaning intact. But 畦 drops you into a particular Japan: rural, humid, the smell of wet earth and growing rice, cicadas somewhere off to the side. A landscape so specific it functions as an emotion.

Notice too that the narrator uses 私 (watashi) — the standard, ungendered first-person pronoun in Japanese. In a catalog where n-buna has frequently written from the 僕 (boku) perspective — the soft, slightly vulnerable masculine “I” that dominates earlier work like “Dakara Boku wa Ongaku wo Yameta” — the shift to 私 carries a different temperature. 私 is more formal, more distanced, more neutral. It could be anyone. Within the Nininshou framework, it’s the voice of a boy writing a poem, trying on the posture of a poet rather than speaking as himself. The pronoun quietly signals that this lyric exists in a literary register, not a confessional one.

Hands That Wipe Sweat, Eyes That Watch Wind

汗を拭う手
Ase wo nuguu te
A hand wiping away sweat

風を待つあの
Kaze wo matsu ano
That [cloud], waiting for the wind

These two images sit side by side, and the juxtaposition is quiet but precise. Down here: a human hand, wiping sweat in the summer heat. Up there: a cloud, waiting for wind to carry it somewhere. Both are suspended in the same moment, both are waiting. The narrator’s eye moves from the body to the sky and finds a mirror.

The trailing あの (ano — “that”) is left dangling, its object implied rather than stated. In Japanese, this kind of trailing demonstrative creates an effect that’s difficult to render in English — it points toward the cloud with a wistfulness that a completed sentence would flatten. It’s the grammatical equivalent of letting your gaze drift upward, mid-thought.

And then:

雲になれたらいいのに
Kumo ni naretara ii no ni
If only I could become a cloud

The refrain, twice. The grammar here matters. ～たらいいのに (tara ii no ni) is the structure of an unfulfilled wish — “it would be nice if [impossible thing], but…” The のに (no ni) at the end carries a sigh of resignation built into the language itself. It’s not “I want to become a cloud.” It’s closer to “wouldn’t it be something, if I could become a cloud” — with the unspoken understanding that you can’t.

And here lies the gap that gives the song its ache: the title is 雲になる — “becoming a cloud,” stated as a fact, as a destination. But the lyrics only ever say 雲になれたら — “if I could become.” The title promises arrival. The song lives in the wanting.

I Am a Jellyfish

The second section shifts something fundamental:

風上の花
Kazakami no hana
Flowers on the windward side

雨の夕焼け
Ame no yuuyake
An evening glow through rain

私は海月
Watashi wa kurage
I am a jellyfish

I had to sit with 私は海月 for a long time. In a song this compressed, where every word earns its place through sheer scarcity, choosing to identify the narrator as a jellyfish is a decision that reshapes the entire poem.

海月 (kurage) means jellyfish, but look at the kanji: 海 (umi, sea) + 月 (tsuki, moon). A “sea-moon.” The creature itself is 95% water, translucent, boneless, moving not by will but by current. It drifts. It glows faintly. It belongs to the deep.

Now consider what a cloud is: water vapor, formless, translucent, moving not by will but by wind. It drifts. It glows when lit by the sun. It belongs to the sky.

The narrator isn’t a person wishing to be a cloud. The narrator is a sea creature wishing to be a sky creature — same substance, different element. The jellyfish and the cloud are both water. One floats in the ocean; the other floats in the atmosphere. The dream here isn’t of escape — it’s of transfiguration. Changing states while remaining, at the molecular level, the same thing.

The word 海月 also sounds nothing like its meaning might suggest. Say it aloud: ku-ra-ge. Three light syllables, the final vowel opening outward, almost floating off the tongue. For a creature associated with the ocean’s dark depths, the word itself feels buoyant — a small phonetic prophecy of the upward yearning the narrator can’t stop expressing.

Rain as a Ladder

The song’s final narrative arc traces a path from sea to sky:

傘を濡らして
Kasa wo nurashite
Wetting the umbrellas

土を濡らして
Tsuchi wo nurashite
Wetting the soil

海を降らせた雲になれたらいいのに
Umi wo furaseta kumo ni naretara ii no ni
If only I could become a cloud that rained down the sea

The repetition of 濡らして (nurashite — “wetting”) creates a cascading effect: rain touching umbrellas, soaking into earth, and — in the final, extraordinary image — a cloud that rained down an entire sea. The verb 降らせた (furaseta) is causative past tense: this isn’t a cloud that fell as rain, but one that made the sea fall. The cloud is an actor, not a victim of gravity.

The sound of these lines reinforces the downward motion. 濡らして (nurashite) starts with the nasal “n,” slides through the liquid “r,” and lands on the sibilant “sh” — the word practically drips as you say it. Hearing it twice in succession, 傘を濡らして / 土を濡らして, creates an auditory experience of water hitting two different surfaces: first the taut fabric of an umbrella, then the soft give of earth. Japanese uses this kind of sonic mimicry instinctively, and n-buna — a lyricist who has always thought carefully about how words feel in the mouth — takes full advantage of it here.

Here’s where the water cycle becomes the song’s hidden architecture. A jellyfish lives in the ocean. Rain falls from clouds into the ocean. Water evaporates from the ocean back into clouds. If the narrator is a jellyfish — a creature of seawater — then becoming a cloud isn’t a fantasy. It’s the completion of a natural process. Evaporation. The poem is secretly about a phase transition that actually happens in nature, dressed in the language of impossible wishing.

The choice of 降らせた (furaseta — “made it rain”) over 降った (futta — “rained”) is worth pausing on. 降った would describe a cloud that simply rained. 降らせた describes a cloud with agency — one that caused rain to fall, that brought the sea down from the sky. The narrator doesn’t want to become just any cloud. They want to become the cloud that carried the entire ocean inside it and then released it. There’s ambition hiding inside this quiet poem.

A Cloud Motif Nine Years Deep

There’s a thread connecting this song back to the very beginning of Yorushika. The duo’s 2017 debut mini-album, Natsukusa ga Jama wo Suru (夏草が邪魔をする / Summer Grass Gets in the Way), contains a track called “Kumo to Yuurei” (雲と幽霊 / Clouds and Ghosts). That song also features 入道雲 — the same towering summer clouds — and carries the line “if only we could keep going far away forever.” The band’s very name, Yorushika, comes from a lyric in that song: 夜しかもう眠れずに (“unable to sleep except at night”).

Nine years later, on their fifth album, the clouds return. But where “Kumo to Yuurei” was a narrative song — characters, a story arc, a full band arrangement powering it forward — “Kumo ni Naru” is barely a whisper. The wish has been distilled. No story, no characters, no names. Just a jellyfish, a summer sky, and the oldest desire in Yorushika’s catalog: to become formless and drift away. The evolution isn’t in the message but in the method — the same longing expressed not through more words but through fewer. Through almost none.

Within the world of Nininshou, this makes a particular kind of sense. The song is framed as the poem of a young writer still learning his craft. There’s a rawness to its brevity that the novel’s conceit explains: this isn’t a polished lyric. It’s a boy reaching for language and finding — in fifty-some words and a handful of images — something that an older, more experienced writer might have buried under ornamentation. The poem works because it doesn’t know enough to be anything other than direct.

What Clouds Sound Like in 7/8

The song’s odd time signature — that perpetual 7/8 slipping into 6/8 — deserves attention, because it mirrors the lyrics’ central metaphor in a way that pure text analysis can’t capture. Clouds don’t move in regular intervals. They stretch, gather, disperse, reform. A song in steady 4/4 time would pin the cloud to a grid. The shifting meter lets it float.

The horn parts, which reviewers have described as drifting in from a distance, reinforce the sense of open sky. Combined with the djembe — a drum associated with communal music played outdoors — the sonic palette suggests a landscape without walls: a paddy field, an open horizon, the kind of place where sound carries differently because there’s nothing to contain it.

And there’s suis’s cold-roughened voice, which n-buna chose to keep precisely because it sounded imperfect. In a catalog built on suis’s crystalline clarity, the decision to use a take where her voice is slightly frayed is an artistic statement. A cloud isn’t clean-edged. It blurs at the borders. The vocal does the same.

雲になれたらいいのに

The song ends where it begins: four repetitions of the same line, 雲になれたらいいのに. No resolution. No shift in perspective. No final verse that reframes the wish. The jellyfish is still a jellyfish. The cloud is still out of reach.

But the title remains: 雲になる. Becoming a cloud. Not “if only.” Not “I wish.” Becoming. As if the song itself — by existing, by being sung, by riding its odd meter into someone’s ears — has already accomplished the transformation that the lyrics can only dream about. The poem, once written, is the cloud. It has left the ocean of the writer’s interior and drifted into the sky of shared experience. The boy in the novel may not know this yet. But n-buna, who set the poem to music that refuses to keep regular time, clearly does.

Within the full arc of Nininshou‘s twenty-two tracks, “Kumo ni Naru” functions as a kind of invocation — placed second, right after the instrumental “Souchou, Yuubinuke” (早朝、郵便受け / Early Morning, Mailbox) that depicts the physical act of opening a letter. You open the envelope, and this is the first poem you find inside. It’s short. It’s imagistic. It doesn’t explain itself. But it establishes the album’s emotional key: a desire, expressed in the simplest possible language, to become something boundless. Everything that follows — the funk of “Shura,” the bossa nova of “Kasou,” the eventual storm of “Kai” — grows from this single, quiet wish. The whole album, in a sense, is an elaboration of the question this song poses: what does it take to change form?

For a band named after a lyric about sleepless nights, who began their career with a song about clouds and ghosts, this return to clouds feels less like repetition than like homecoming. The vocabulary hasn’t changed. The ambition has. In 2017, the wish was to “keep going far away forever.” In 2026, it’s something more radical: not to go anywhere at all, but to become the going itself. To be the cloud, not the person watching it.
