Ministop, a major Japanese “Konbini” (convenience store), will release “Hokkaido Wave Potato Shiawase Butter” across Japan starting Friday, April 10, 2026. This new item is a limited-time collaboration between Ministop’s popular “hot snack” (freshly prepared in-store menu) fried potatoes and Calbee’s legendary snack, “Potato Chips Shiawase Butter.” This menu allows you to enjoy the fluffy texture of Hokkaido potatoes combined with the beloved Japanese “sweet and savory” (amajoppai) flavor profile all at once.
A Powerful Collaboration Between Calbee’s Ultra-Popular Flavor and Ministop
The iconic taste of Calbee’s hit snack “Potato Chips Shiawase Butter” has been recreated for Ministop’s “Hokkaido Wave Potatoes.” “Shiawase Butter” (which translates to “Happy Butter”) is a flavor characterized by the exquisite sweet and salty balance of butter and honey, earning it massive support in the Japanese potato chip market.
This new release features a “wave cut” shape for the potatoes. This specific cut is designed to better catch the seasoning powder, allowing you to fully enjoy both the fluffy potato texture and the rich flavor simultaneously. The result is an addictive taste that fuses the fun of a snack with the deliciousness of freshly prepared fries.
A “4-Happiness” Flavor Created by Four Ingredients
The secret to this product’s deliciousness lies in the “Shaka-shaka” powder supervised by Calbee. The name “Shiawase” is a Japanese wordplay combining “Happiness” (Shiawase) with the “Four Ingredients” (4 = Shi) used in the seasoning:
- Butter: For a rich and savory aroma.
- Honey: For a gentle, natural sweetness.
- Parsley: For a touch of color and a flavor accent.
- Mascarpone Cheese: For a mellow and deep creaminess.
The layering of these four ingredients creates a deep and luxurious harmony. Sprinkled with vibrant green parsley, the final product is as visually appealing as it is appetizing.

Simply sprinkle the powder over the potatoes in the provided bag and shake it (Shaka-shaka) to season them to your liking.
This interactive experience ensures that the fresh aroma of the powder is released just as you are about to eat, making it feel like it was just made. Since the wave-cut shape catches the powder perfectly, you can enjoy the rich “Shiawase” flavor down to the very last bite.
