Nagare Boshi ~Shooting Star~ (流れ星〜Shooting Star〜)

Sky (object) if-look-up, stars (subject) look, twinkling-are

瞬く (またたく) is the verb for the twinkle of stars (and blinks of an eye). Adding たち onto 星 ('stars-plural') is a soft personification — treating stars as individuals.

This planet's people like, various light (object) emit

星 in Japanese covers both 'star' and 'planet' — context decides. Here この星 ('this planet/star') is Earth, and the line compares earth's people to the celestial stars overhead.

That among in, I also conspicuously be-shining-want (it.is)

ひときわ (一際, 'one notch above') is a literary adverb for 'standing out / conspicuously / above all'. Slightly elevated register — common in lyrics and prose, less in casual speech.

Eyes (object) closing, heart in vow, shooting-star to dream (object) entrusting

託す ('to entrust / leave (something) with someone') has a transactional weight — handing over the dream as a parcel for the star to deliver. 流れ星 ('flowing star' = shooting star) is the Japanese version of the wishing-star idea.

Here (topic) usual park, night-view (subject) is-visible slide's on-top

滑り台 ('slide') is the playground equipment. Climbing to the top of a park slide as your private hangout spot is a classic Japanese hip-hop image — 'street poet on the kid's slide'.

Long-ago from, my best-seat

特等席 (literally 'special-class seat') is the front-row, first-class seat at a theater or stadium. Used metaphorically for 'the best vantage point'. Calling a slide your 特等席 is winking at urban-poet self-deprecation.

Worry if-exists, here to come (it.is)

That-time as-is, dream's middle in, still without-being-able-to-grant am (it.is)

未だ (いまだ) is a literary 'still / not yet' — heavier than just まだ. Often appears in news, formal writing, lyrics. 〜ずにいる ('to be in a state of not having done X') is the literary 'still haven't' construction.

Maybe here (subject) already terminal-station such-as, weak-words (object) let-out-completely-likely day also exists

弱音を吐く ('to let out weak words / complain about being unable to do something') is a fixed idiom — vocalizing despair. Considered un-manly in shounen culture, so admitting to it is a sign of vulnerability. 終点 ('end of the line') extends a train metaphor.

But that-each-time at, remember, shooting-star (object) searched that starry-sky

そのたんび is the casual contraction of そのたびに ('each time'). The 旅 (たび, 'journey') etymology gives it a continuous-loop sense — each time the worry comes, the same memory comes too.

Small time's wish (topic), now, long-ago, doesn't-change as-is

Night's school-building, comrades with sneaking-in

忍び込む = 忍ぶ ('to bear / hide') + 込む ('into'). Same 忍 kanji as in 忍者 (ninja). Used for sneaking into a place stealthily — schools, parties, etc. Setting up a classic 'kids sneaking out' anecdote.

Voice (object) lower, wire-fence climb-up

声を潜める ('to lower one's voice / hush') is the standard idiom for whispering during sneaky activity. 金網 ('wire fence') = the chain-link fence around school grounds — a classic setting for nighttime mischief in Japanese youth memoir.

Aimed-for place (topic) pool that's-called name's ocean

〜という名の〜 ('an X called Y') is a fixed pattern for naming with flair. プールという名の海 ('an ocean called pool') is the song's poetic way of glamorizing the school pool.

Swimsuit such-as thing (topic) doesn't-exist because, everyone stark-naked

すっぱだか (素っ裸, 'stripped-bare') with the emphatic prefix すっ. すっぱだかになる ('to strip naked'). The line lands the song's most vivid memory image — preteen mischief at maximum freedom.

Someone (subject) weird-shout (object) letting-out, jumped-in

奇声 (literally 'strange voice') is a wild, wordless shout — what people make when they're cannonballing into a pool or panicking. 飛び込む ('jump in') = 飛ぶ + 込む ('into').

Night's veil in resound, water-splash

夜の帳 ('night's veil/curtain', literally 'the curtain of night') is a poetic phrase for night-time, evoking how darkness drapes over the day. 帳 was originally a hanging curtain in old Japanese homes.

After at, continued just-because, everyone all-at-once enter

一斉に ('all at once / simultaneously') is a literary adverb. Used for synchronized actions: 一斉に立ち上がる ('rise as one'), 一斉に始める ('all start at the same time').

Sky looking-up, puka-puka float (past)

ぷかぷか is the mimetic adverb for objects bobbing on water — boats, kids in a pool, leaves on a stream. Reduplication doubles the bobbing rhythm. Common in children's books and casual descriptions.

Eye's-front in exists stars (object) gazing, many dreams talking-with-each-other, searched (right?), that shooting-star

語り合う ('to talk with each other / share thoughts') is the gentler, more reciprocal version of 話す. The compound 〜合う makes it mutual: shared confession, not one-sided talk.

Looked-up sky in countless stars, now-and long-ago doesn't-change

Dream (topic) endless maddening-and, those stars like extremely dazzling

狂おしい (literally 'maddening / driving one mad') is from 狂う ('go mad'). Used for love, desire, or longing so intense it's almost crazy. 〜おしい forms a small family of intense-feeling adjectives: 愛おしい (lovable), 懐かしい (nostalgic).

Hey, that-much look-down only if, visible things even become-invisible because

俯く ('look down dejectedly') vs 下を向く (just 'face down'). 俯く specifically implies emotional defeat or shame. The line is a peer's gentle prod: stop sulking.

Sky look-up, keep your head up
