Submarine Youth Lyrics English Translation by Masahiro Hirabe | Regretgirl
Masahiro Hirabe describes two people navigating a tender, uncertain relationship. They hold their breath and share the moment, creating intimate snapshots of daily life. The lyricist shows how love can be both confusing and clear, as the narrator admits ‘Thinking that our secrets are beautiful’ (Himitsu o kirei ni omou no wa) is something they hope the other person feels too. He paints a picture of imperfect days that are cherished exactly as they are.
Oboenai yume no you na kimi toWith you, who feels like a dream I can’t quite remember,
Iki o hisome wakachiaeruwe hold our breath and share this moment.
Himitsu o kirei ni omou no waThinking that our secrets are beautiful,
Boku dake janai yo neisn’t something only I feel, right?
Bukiyou demo tada massugu niEven if I’m clumsy, I’ll just be straightforward.
Dekiru dake sunao de iru karaI’ll be as honest as I possibly can,
Boku ni mo yoku wakatte inaiso this feeling I don’t even fully understand myself,
Kono omoi o issho ni mitsukete yolet’s discover it together.
Kyou wa hitori de sugoshi te itai tokaSometimes I say I want to spend today alone,
Haru ga nigate demo hontou waor that I don’t like spring, but the truth is,
Dareka to iru no wa kirai janaiI don’t hate being with someone.
Soba ni irareru koto ni banbanzaiI’m completely thrilled just to have you by my side.
Hitori ni natta toki wa hanseikaiWhen I’m alone, I overthink everything I did.
Tsumazuku koto mo aru keredoThere are times when I stumble and make mistakes,
Warattari naitari omoidashite irubut I’m remembering the times we laughed and cried,
Sukoshi zutsu peeji o mekuru you nilike turning the pages of a book, little by little.
Maki modosu you ni omoi megutte iruMy thoughts are spiraling, like rewinding time.
Asa o matsu shizuka na umi o oyogu you niLike swimming through a quiet sea waiting for the morning,
Nando mo nando mo kimi no moto e yureruI drift toward you, over and over again.
Kimi to iru toki no jibun no sugata oThe way I am when I’m with you,
Suki da to omoeru karais someone I can actually like,
Hontou no kimochi o ima koko deso I feel like I’ve finally found,
Mitsuketa you na ki ga shita yomy true feelings right here and now.
Suki dakedo kirai toka itte mitariSaying things like I love you but I hate you,
Kirai dakedo suki tomo itte miteor trying to say I hate you but I love you.
Furikaeru koto mo aru keredoThere are times I look back on the past,
Fukanzen demo ari no mama kurasu hibibut these imperfect days of living just as we are,
Ga suki dakaraare what I truly love.
Kimi no subete o oshiete yoTell me absolutely everything about you.
Sukoshi zutsu yukkuri de ii karaIt’s fine if it’s little by little, taking our time,
Yuuyake ni nobiru futari no kage gaso that our two shadows stretching in the sunset,
Kesshite kasanattari wa shinai you ninever completely overlap and lose their shape.
Muri ni fumikonde konai karaYou don’t forcefully step into my space,
Umaku kotoba ni dekizu nayamu keredoand though I struggle to put things into words,
Kimochi ni uso wa nai yothere are absolutely no lies in my feelings.
Warattari naitari omoidashite iruI’m remembering the times we laughed and cried.
Fukai umi no ue o oyogu you niLike swimming above the deep, dark sea,
Nando mo nando mo tashikame aou yolet’s reassure each other, over and over again.
Nagasarenai you ni te o nigiru karaI’ll hold your hand so we don’t get washed away,
Moratta kotoba o dakishimete iruholding tightly onto the words you gave me.
Ima nara me o mite tashika ni ieru yoNow, I can look into your eyes and say it for sure.
Itsu made mo itsu made moForever and ever,
Futari rashiku tsuzuku you niI hope we continue on, just being ourselves.
