Japan Post is no stranger to epic anime collabs, having previously teamed up with giants like Attack on Titan, Yu-Gi-Oh!, and Neon Genesis Evangelion. Their limited-edition merchandise often sells out faster than major brands!
Now, they're back with another adorable partnership, this time featuring the mega-popular "Chiikawa" from illustrator NAGANO! Get ready for a special "New Year's Postcard 3-Piece Set & Sticker Set," perfectly themed for the Year of the Horse. Mark your calendars: this charming collection drops on November 14, 2025, at approximately 200 post office branches across Japan, with online pre-orders also available via the Japan Post online store.

This New Year's postcard set is all about 2026's zodiac animal: the horse! The design features Chiikawa, Hachiware, and Usagi transformed into adorable ponies, happily galloping along. Each set comes with three identical postcards, so you can spread the cuteness far and wide.

But wait, there's more! The set also includes a super-duper cute decorative sticker sheet, starring our favorite little pals in their horse outfits, munching on carrots. Stick 'em on your postcards, envelopes, or even your notebooks to add a personalized, utterly adorable touch to your New Year's greetings!

Each set will retail for 880 JPY. If you're a Chiikawa fan looking to kick off the Year of the Horse with maximum cuteness, you'll definitely want to snag this adorable collection!
