Autumn is sweet potato season in Japan, and it brings a round of limited-edition flavors to familiar snacks. All five Japanese sweet potato snacks in this list are limited-time releases, so each one is something to look for while the season lasts.
Sweet potato meets white chocolate in a moist cookie and butter in a thin cream sandwich. A roll cake pairs moist cake with sweet potato cream, and one light snack adds a pinch of salt for a sweet-and-salty bite.
Sweet Potato Flavors for Fall in Japan
Ever noticed how a familiar snack can feel new when the season changes? In Japan, autumn is when sweet potato flavors arrive in cookies, corn snacks, and cakes.
The five picks below range from sweet baked treats to a lightly salted snack. Every one of them is a limited-edition release for autumn or the cooler months, so these seasonal Japanese snacks are around for only part of the year.
5 Limited-Edition Sweet Potato Picks
Think mitsuimo paired with white chocolate, or roasted sweet potato finished with a pinch of salt. Each of these autumn limited editions puts sweet potato into a different combination.
Country Ma'am Jukusei Mitsuimo – Soft Cookie with Sweet Potato and White Chocolate

This limited-time Country Ma'am cookie pairs the rich sweetness of mitsuimo, a name used in Japan for very sweet, moist sweet potatoes, with white chocolate chips. The dough is made with sweet potato paste from Beni Tenshi sweet potatoes grown in Ibaraki Prefecture, and the cookie has a moist texture. Warming a cookie for a moment brings out a taste that recalls mitsuimo itself.
COUQUE D'ASSES Satsumaimo Butter – Thin Cookies Sandwiching Sweet Potato Cream

Yellow sweet potato cream sits between thin, crisp langue de chat cookies made with purple sweet potato powder, so sweet potato flavor comes through in both the cookie and the cream. This autumn limited edition has a light, crisp bite and a buttery aroma.

With Country Ma'am, try a cookie as it is, then taste one warmed for its mitsuimo-inspired flavor.
Yaki-Imo and Japan's Autumn Treats
Snack time in Japan can be as simple as a whole roasted sweet potato. Known as yaki-imo, it has been enjoyed since the Edo period, several centuries ago. The potato's sweetness and texture are central to this familiar snack.
For yaki-imo, the choice of sweet potato matters. Sweet potatoes such as Anno imo and Beni Haruka have helped make very sweet, moist yaki-imo popular. On a snack package, "Anno Imo" points to a particular kind of sweet potato and the sweetness associated with it.
The eating season also continues after the autumn harvest. Under suitable storage conditions, many varieties become sweeter over time, and sweet potatoes can be enjoyed into winter.
Country Ma'am draws on the rich sweetness of mitsuimo, while Osatsu Snack includes roasted sweet potato in its dough. Both connect the sweet potato tastes familiar from yaki-imo with everyday packaged snacks.
Conclusion
Autumn in Japan brings sweet potato into many kinds of treats, and every pick on this list is a limited-edition release. The same seasonal flavor comes through in cookies, light snacks, and cake, each paired with different ingredients.
