NMB48 – Himitsu nikki. Lyrics Meaning: Turning Your Secret Diary into a Runway

Why do we write down feelings we’d never say out loud? NMB48’s song “Himitsu nikki” is all about that secret book. It’s a peek into a diary filled with sadness and frustration, but with a hopeful twist.

    The Story Inside NMB48’s “Himitsu nikki”

    The whole song feels like someone is flipping through the pages of their old diary. It’s not just a book; it’s a place where they stored their truest, most unfiltered emotions. This isn’t about happy memories. It’s about the tough stuff.

    Hearing Your Own Heart

    The song kicks off by describing the act of writing. It’s a private moment. She’s not writing for an audience. She’s writing to hear the voice of her own heart, clear and simple.

    Dare ni mo iwazu ni kaki tsudzuketa
    I kept writing without telling anyone
    Sono toki kikoeta kokoro no koe
    At that time, I heard the voice of my heart

    A Place for Unfiltered Feelings

    This diary is a safe space for the feelings we usually hide. It’s where she poured out all her frustration and sadness. The moments that hurt the most are the ones that filled the pages.

    Kanashii toki toka kuyashii toki
    When I was sad or frustrated
    NOOTO ni tsudzutta himitsu nikki
    I spelled it out in my secret diary

    She makes it clear this was just for her. If she knew someone else would read it, she would have sugarcoated everything. She would have made herself look better. But this diary contains the real, sometimes “ugly,” truth.

    Dareka ni miseru to kimete itara
    If I had decided to show it to someone
    Subete wo bika shite kaiteta deshou
    I probably would have beautified everything I wrote

    The Core Idea of “Himitsu nikki”

    This song is all about looking back at your painful past, not with regret, but as a necessary part of your journey. All those scribbled-down feelings weren’t a waste of time. They were the building blocks for the person she is today. The diary is a symbol of her growth, turning raw emotion into strength.

    The Beautiful Message from NMB48

    The big takeaway here is super positive. It’s about how your past struggles don’t define you in a negative way; they actually prepare you for what’s next.

    Your Scars Become Your Strengths

    The lyrics have this amazing visual. The tears she cried have now dried up and left behind a beautiful pattern. It’s a powerful way of saying that your pain can create something unique and strong within you. Her long, hard path wasn’t a dead end. It was a running start for her future.

    Ano namida wa mou kawaite
    Those tears have already dried
    Ima kirei na moyou ni naru
    Now they form a beautiful pattern
    Ayunde kita nagai michinori ga
    The long path I’ve walked
    Mirai e no josou da
    Is a running start into the future

    You Were Never Really Alone

    Here’s the other cool part. While she felt alone writing in her diary, looking back, she realizes people were always there. Friends, maybe family, were supporting her from the sidelines. That quiet support gave her the comfort she needed to get through it all.

    Furikaereba donna toki mo
    When I look back, no matter when
    Watashi no soba ni dareka ga ita
    There was always someone by my side

    Lyrics: "Himitsu nikki" by NMB48


    NMB48 – Himitsu nikki [Lyrics KANJI]


    誰にも言わずに書き続けた
    その時聴こえた 心の声

    悲しい時とか 悔しい時
    ノートに綴った秘密日記

    今日まで 溜まってた感情を
    紙飛行機にして 窓から飛ばそうか

    あの涙は もう乾いて
    今 綺麗な模様になる
    歩んで来た長い道のりが
    未来への助走だ
    仲間たちを忘れないよ
    励まし合った青春の日々
    悔いなどない そっとつぶやいても
    心のどこかに
    少し重い痛みがある

    誰かに見せると決めていたら
    全てを美化して 書いてたでしょう

    本当のそう自分でいたいから
    醜い心も素直に曝(さら)け出した

    ヒリヒリしたあの気持ちを
    そうはっきり 覚えてるよ
    目を閉じれば 走馬灯のように
    一瞬の幻
    振り返れば どんな時も
    私のそばに 誰かがいた
    その背中に あなたの気配を
    いつも感じてたから
    ほっとできた やさしい日向

    あの涙は もう乾いて
    今 綺麗な模様になる
    歩んで来た長い道のりが
    未来への助走だ
    仲間たちを忘れないよ
    励まし合った青春の日々
    悔いなどない そっとつぶやいても
    心のどこかに
    少し重い痛みがあ

    NMB48 – Himitsu nikki [English translation]


    I kept writing without telling anyone,
    And in those moments, I heard the voice of my heart.

    When I was sad or frustrated,
    I penned it down in my secret diary.

    All the feelings I’ve accumulated until today,
    Should I make them into a paper airplane and let them fly out the window?

    Those tears have already dried,
    And now they’ve become beautiful patterns.
    The long path I’ve walked
    Is a run-up to the future!
    I won’t forget my friends,
    Those days of youth we spent encouraging each other.
    Even if I softly whisper, “I have no regrets,”
    Somewhere in my heart,
    There’s a slightly heavy ache.

    If I had decided to show it to someone,
    I probably would have beautified everything I wrote, right?

    Because I want to be my true self,
    I honestly exposed even the ugly parts of my heart.

    I remember that stinging feeling
    So clearly.
    If I close my eyes, like a revolving lantern,
    It’s a fleeting illusion.
    Looking back, someone was always by my side,
    No matter what.
    Because I always felt your presence behind me,
    I could relax in that gentle, sunny spot.

    Those tears have already dried,
    And now they’ve become beautiful patterns.
    The long path I’ve walked
    Is a run-up to the future!
    I won’t forget my friends,
    Those days of youth we spent encouraging each other.
    Even if I softly whisper, “I have no regrets,”
    Somewhere in my heart,
    There’s a slightly heavy ache.
