New year, new balls. (Hagoromo Co., Ltd./PRTimes)
Japan’s “Nyantama Calendar” is a calendar with pictures prominently presenting cat balls. You heard that right. Checking your schedule for the day? Then you’ll start your morning with a full-frontal feline surprise. Crossing off a productive day before bed? Congratulations, your night ends with a tender glance at a cat’s fuzzy undercarriage. The Nyantama calendar, now a returning favorite, is the work of publisher Hagoromo, who has openly admitted it started as a gag. The testicle calendar was specifically designed for “nyantama” fans, with “nyan” being the Japanese word for “meow”, and “tama” being slang for balls. Put it together and you get “Meow-nuts.” It’s almost poetic.
Each month features a 15.7 x 11.8-inch high-quality photo of a cat’s backside. In addition to its highly-specialized visual appeal, the Nyantama Calendar also packs an unexpected bonus: fortune-telling. The full name, The Good Luck Nyantama ω Calendar, hints at its second purpose. Alongside the year’s supply of kitty crotch photography, the calendar includes detailed daily luck predictions based on a mash-up of Japanese folk fortune traditions. Were not exactly sure if the ω symbol is meant to be read as “omega” or because it looks suspiciously like a testicle. In my opinion, we’re leaning toward the latter.
Because who doesn’t carry a pocket-sized pair for good luck? (Hagoromo Co., Ltd./PRTimes)
It gets even nuttier. Purchasing the calendar through Amazon Japan or Rakuten gets you a wallet-sized good luck nyantama card, allowing you to carry a tiny photo of a cat’s privates with you wherever you go. Most people keep their significant others or kids in their wallet. But these cards allow you to have cat testicle photos close at hand, even when you have to leave the comfort of your cat testicle calendar-decorated home. The cards are meant to be a token of good luck, but could lead to an awkward conversation when someone sees it, which could lead to an intervention.
The 2025 edition retails for 1,760 yen (about $12 USD), and is available now for pre-order on Amazon. While the creators haven’t confirmed any official monthly themes, we can only hope they’ve leaned into the potential. Picture December: a cozy winter scene, snow gently falling, and a cat batting at their own snow-balls with a festive caption like “Deck the balls with paws of jolly.” As strange as it sounds, the Nyantama Calendar has clearly found its audience. Maybe it’s the absurdity. Maybe it’s the nobility of a well-framed feline scrotum. Whatever it is, people aren’t just tolerating it—they’re going nuts for it.
