In 2024, the "1/1 Pure Gold Baby-Star Ramen (Chicken Flavor Model) K24" and "1/1 Pure Platinum Baby-Star Ramen (Umashio Flavor Model) Platinum 999" followed, and in 2025 the "Pure Gold Miniature Figure BUTAMEN-kun" was also featured on television and drew a large response.
This year's new release turns Baby-Star Ramen noodles and the BUTAMEN fork into precise miniature models cast in pure gold. Each piece comes in a card-sized format so it can be carried in a bag or wallet. Free from the conventions of typical jewelry, every piece is carefully hand-crafted one at a time, delivering a special golden shine that feels fitting to own now that you're an adult. Enjoy these collector's items, which capture the familiar Baby-Star Ramen noodles and BUTAMEN fork in gleaming pure gold.

About the Baby-Star Day Campaign
Baby-Star was born in 1959 from the avant-garde idea of eating ramen noodles just as they are, and it has continued to bring excitement to fans ever since with unique product ideas that break free of convention.
Following a change of the Baby-Star character in 2017, the brand has focused not only on offering fun, interesting products but also on creating shared experiences enjoyed together.
Snack time — a moment to catch your breath amid busy days — is more than just a quick energy boost; it's a heart-lifting experience. Because Baby-Star is fun to eat all on its own, the brand wants to bring that same excitement to even more people by presenting it in different forms. With that in mind, Oyatsu Company will continue to share news about events and limited-edition products that make those exciting, smile-filled moments even more special.
Opening a bag of Baby-Star and eating it naturally lifts both your mood and your face. Even if you spill a little, everyone around you somehow ends up smiling too — why not enjoy some exciting time with Baby-Star, the fun snack?
