News has arrived from Calbee, a famous Japanese snack manufacturer, about the release of a special potato chip. Its name is “Potato Chips Shiawase Butter – Creamy Style.” This product will be available for a limited time at convenience stores nationwide in Japan starting Monday, November 24, 2025.
What is “Shiawase Butter”? A Classic Japanese Potato Chip Flavor
Some of you might be wondering what “Shiawase Butter” even is. It’s one of the most popular flavors among Calbee’s potato chips. It’s a core product, ranking as the fourth most popular flavor after long-standing classics like “Lightly Salted” and “Consommé Punch.”
Its charm lies in the exquisite “sweet and salty” taste, a combination of four ingredients: butter, honey, mascarpone cheese, and parsley. True to its name, “Shiawase” (which means happiness), it continues to be loved by many fans who say it makes them feel happy when they eat it. Celebrating its 15th anniversary this year since its launch in 2010, it can truly be called a nationally beloved flavor.

Features of the New “Creamy Style”
The new “Potato Chips Shiawase Butter – Creamy Style” is, as the name suggests, an evolution of the classic “Shiawase Butter,” made even creamier.
By enhancing the flavor of mascarpone cheese in particular among the four ingredients, it achieves a gentler, creamier sweet-and-salty taste, almost like a dessert. It offers a taste that will be a pleasant surprise not only for existing “Shiawase Butter” fans but also for those trying it for the first time.
The packaging design is also special. While based on the classic yellow and orange color scheme, it features a stylish, café-sign-like design that creates a sense of specialness, setting it apart from the usual look.
Product Details
This new flavor comes in a 55g bag with an estimated price of around 170 yen (tax included). It is sold exclusively at convenience stores nationwide in Japan and is scheduled to be discontinued in late December 2025, so if you are in Japan and happen to see it, be sure to try it early.
