Chainsmoker Cat: OP Theme "Nanmonee" Drops

On July 28, Netflix Japan's own channel posted the opening theme for Chainsmoker Cat (ヤニねこ) — and across 442 comments, the reaction split between playing animation detective and gushing, half-embarrassed love for a song attached to a show about smoking behind a supermarket. The top comment, with 642 likes, is just someone noticing the cat in the opening doesn't land on its feet.

From there it swung between running jokes (Netflix officially co-signing the show's filth drew 673 likes worth of mock alarm) and real appreciation — one widely-liked comment called the lyrics genuinely moving despite the show's reputation, and an 820-like comment about a 60-year-old husband who's gotten hooked became the thread's most-liked story.

The comment section policed itself, too — one reply pointed out that YouTube's own "keep it civil" guidelines don't stand a chance on this particular video.

Netflix Japan's own YouTube channel posted the opening theme for Chainsmoker Cat — "Nanmo Nee" by the band Wasurerannee yo — on July 28, and the 442 comments underneath immediately split into two camps: people playing animation detective on individual frames, and people fessing up to genuinely loving a song attached to a show about two adults smoking behind a supermarket.

That detective energy set the tone for the whole thread, with viewers timestamping individual seconds of the animation to point out sight gags and parody references buried in the sequence. But just as much of the comment section was busy processing something that felt almost surreal — the biggest streaming platform in the world had, apparently, officially co-signed one of the filthiest-mouthed shows on TV.

Once the shock wore off, the thread pivoted into something closer to a defense of the song itself. Vulgar source material or not, plenty of commenters wanted it on record that the theme is genuinely good on its own merits — not a guilty pleasure, just good, and one commenter went as far as calling it the best anime song of the year.

Specific lines from the lyrics kept coming up too, usually with a note that they land harder than a song for a show like this has any right to — bittersweet in a way that caught people off guard.

Part of what people kept circling back to was exactly that mismatch — a stylish, well-produced theme song for a show that revels in being disgusting, and somehow both halves of that equation work.

And then, buried a few replies down, was the comment that ended up as the thread's real centerpiece — not about the animation or the lyrics, but about who's actually watching this show every week.

Nobody in the replies seemed remotely surprised by that one. If anything, it matched the general mood of the comment section, which more or less policed its own behavior by the end, joking that even YouTube's own guidelines didn't stand a chance here.

Which, on a video for a show literally named after chain-smoking, might be the most fitting review Chainsmoker Cat has ever gotten.
