NMB48 – Mousou Machine 3gouki. Lyrics Meaning: A Boyfriend’s Wild Imagination

Why do our minds sometimes wander, even when we’re totally happy in a relationship? NMB48’s fun track “Mousou Machine 3gouki” dives into this exact idea. It tells the hilarious story of a guy whose imagination runs a little wild.

    The Story Inside NMB48’s “Mousou Machine 3gouki”

    This song is basically a peek inside a guy’s brain. He’s with his girlfriend, but his thoughts start drifting. It’s a funny, relatable story from start to finish.

    A Simple, Dangerous Question

    It all begins when he sees another cute girl. This sparks a ridiculous thought: just how much love can his heart actually hold? He’s completely loyal to his girlfriend, but his brain starts doing some silly math.

    Kono mune no ai no utsuwa ittai dorekurai hairunda?
    Just how much can this vessel of love in my chest hold?
    Kimi igai no onnanoko ga ki ni natte shimatta
    I’ve started to notice girls other than you

    He knows his girlfriend is number one, of course. But he daydreams about having just a little more room in his heart for someone else. It’s a classic case of a wandering eye that’s all in his head.

    Meet the “Mousou Machine”

    His girlfriend totally catches on. Instead of getting mad, she just laughs at him, calling out his silly dreams. This is where he powers up his imaginary gadget: the “Mousou Machine 3gouki,” or “Delusion Machine No. 3.” It’s his brain going into full daydream mode.

    Mousou mashiin sangouki
    Delusion Machine No. 3
    Ima suicchi wo ON ni shite mo
    Even if I turn the switch ON now
    Atama ga katte ni
    My head just on its own
    Imeeji wo fukuramaseteru dake
    Is just expanding the image

    The joke is that this “machine” is just his own mind. He admits he’s way too much of a coward to ever act on these thoughts. It’s a safe way for him to have a little “mental affair” without any real consequences.

    It’s All Just for Fun

    He even apologizes for his little mental adventure. He realizes his heart is already overflowing with love for just one person: her. He feels like he should be a “bigger man,” but the truth is, his world revolves around his girlfriend. The machine always breaks down because she sees right through him. She’s the one in control, his “queen.”

    Genjitsu wa okubyou de
    In reality, I’m a coward
    Boku ni wa sonna yuuki wa nainda
    I don’t have that kind of courage
    Kibun dake uwaki shite mitakatta
    I just wanted to try cheating in my feelings
    Gomen nasai
    I’m sorry

    So, What’s NMB48’s Song Really About?

    The core story of “Mousou Machine 3gouki” is the funny contrast between a guy’s wild imagination and his loyal reality. The “machine” is just a metaphor for his brain’s ability to cook up silly “what if” scenarios. He’s not a cheater; he’s just a daydreamer who is completely devoted to his girlfriend. She knows it, he knows it, and that’s what makes their dynamic so cute and funny.

    The Sweet Message Behind the Silly Daydreams

    Believe it or not, there’s a really positive message here. The song shows us that thoughts are not the same as actions. A strong, trusting relationship can handle a bit of harmless daydreaming. His girlfriend isn’t threatened by his “Mousou Machine” because she’s secure in their love. It’s a lighthearted reminder that a little imagination is fine, as long as your heart knows where it belongs. It’s about loving someone, goofy daydreams and all.

    What’s your take on this song? Do you think it’s just a funny story, or is there a deeper meaning to his “Delusion Machine”? Let me know what you think!

    NMB48 – Mousou Machine 3gouki [English translation]


    I’ve been wondering…
    Your girlfriend is so cute!

    Just how much love can this heart of mine hold, I wonder?
    I ended up getting interested in other girls besides you.
    Of course, you know that you’re my one and only true love, right?
    But still, I feel like I could handle love for one more person!

    She noticed my little scheme,
    And laughed beside me.
    “Don’t dream such silly dreams!” she said.

    My Delusion Machine No. 3,
    Even if I switch it ON now,
    My mind just
    Keeps expanding on its own, building up images.
    Reality is cowardly,
    And I don’t have that kind of courage.
    I just wanted to feel like I was cheating for a bit.
    I’m so sorry!

    Oh, my love container is so small, it fills up so quickly!
    It’s overflowing with just you, there’s no more capacity.
    Perhaps it would be nice to have a little more room, wouldn’t it?
    I think I need to become a bigger man.

    “Even if you make your container bigger, it won’t change a thing.
    It’s full to the brim with love for me.
    There’s no need to do anything pointless.”

    My Delusion Machine No. 3,
    It stopped working halfway through again.
    Even though I improved it,
    You always end up breaking it.
    I don’t need things like that!
    I tried removing the thermostat, but
    In the end, I’m still remotely controlled by you.
    My Queen!

    Delusion Machine No. 4,
    Come on, let’s develop a new one!
    So it can’t be read,
    I need to strengthen its security.
    A stealth-type for the heart!

    My Delusion Machine No. 3,
    Even if I switch it ON now,
    My mind just
    Keeps expanding on its own, building up images.
    Reality is cowardly,
    And I don’t have that kind of courage.
    I just wanted to feel like I was cheating for a bit.
    I’m so sorry!

    Hey, please overlook it.
    Just a little bit.

    It’s just a delusion!
    (For a moment)
    I love you!
    (Forever)
