Words Bubble Up Like Soda Pop

The Summer That Spoke in Haiku

I’ve always been suspicious of films that promise “a brief, magical summer.” The phrase feels like a marketing tagline, a shorthand for nostalgia that hasn’t yet earned its wistfulness. But Words Bubble Up Like Soda Pop sneaks up on you. It doesn’t announce its magic; it lets it fizz quietly, like the last sip of a soda left in the sun.

By the time the credits roll, you realize you’ve been holding your breath—not because the story is particularly dramatic, but because it’s so specific. This isn’t a generic coming-of-age romance. It’s a film about the way words fail us, and the strange, stubborn ways we find to say them anyway.

The premise is simple: two teenagers, Cherry and Smile, meet by chance in a small town during a heatwave. Cherry (voiced by Somegoro Ichikawa) is a painfully shy boy who communicates almost entirely in haiku, scribbling verses in a notebook he never lets anyone read. Smile (Hana Sugisaki) is a social media-obsessed girl who hides her face behind a surgical mask, convinced she’s too ugly to be seen.

Their connection is tentative, awkward, and entirely believable—less a grand romance than a series of small, stumbling steps toward something like understanding. The film’s title isn’t just whimsy; it’s a thesis. Words do bubble up, unpredictably, messily, like soda pop shaken too hard.

The question is whether anyone’s there to catch them.

What’s striking about Words Bubble Up Like Soda Pop is how little it relies on traditional anime tropes. There are no over-the-top action sequences, no supernatural elements, no villains to defeat. Instead, the film finds its tension in the mundane: a missed train, a forgotten record, a mask that won’t stay on.

The animation style is soft and understated, with a color palette that leans into the hazy golds and blues of a summer evening. The backgrounds are lush but never distracting, as if the film itself is trying not to draw too much attention to its own beauty. (I kept thinking of Makoto Shinkai’s Your Name, but without the apocalyptic stakes—this is a film that believes small moments can be just as transformative as world-ending disasters.)
