Satsuma Kintsuba is a traditional confection from Kagoshima Prefecture, made with locally grown sweet potatoes. Produced by Baba Seika, it combines the natural sweetness of sweet potatoes with the craftsmanship of experienced Japanese confectioners.
The confection is made using four varieties of sweet potato: Kogane-imo, Hayato-imo, purple sweet potato, and Anno sweet potato. Kagoshima-produced hon-kuzu (high-quality kudzu starch) is also used. Skilled confectioners carefully knead the sweet potatoes, shape them into squares, and bake each piece by hand.
The result is a simple, gentle flavor that brings out the natural sweetness of the sweet potatoes. The confection is popular with people of all ages and has received awards at numerous confectionery competitions and other events. It is regarded as one of Kagoshima’s proud traditional sweets.
Baba Seika was founded on Yakushima in 1910 and has continued to develop confectionery rooted in the island’s local culture. The company began producing Satsuma Kintsuba using Kagoshima’s specialty sweet potatoes in 1973.
Its approach combines traditional Japanese confectionery techniques with the distinctive agricultural products of Kagoshima. The company also places importance on the quality and safety of its products, and Satsuma Kintsuba is made without additives.
Kintsuba is a type of traditional Japanese confectionery. In one common style, chunky sweet azuki bean paste is set into a square shape using agar, then each side is baked on a heated copper plate.
The original form of kintsuba was made by kneading wheat flour with water, rolling the dough into a thin sheet, and wrapping it around sweet bean paste. The confection was then shaped into a flat round form and cooked on both sides and around the edges in an oiled pan.
Satsuma Kintsuba gives this traditional confection a distinctly Kagoshima character by using sweet potatoes in place of the usual azuki bean filling. Depending on the preparation, sweet potato paste may be wrapped in dough, or square pieces of sweet potato yokan may be coated on each side with dough and baked.
By combining the traditional kintsuba technique with Kagoshima’s locally grown sweet potatoes, Baba Seika has created a regional confection that highlights the natural flavor of the prefecture’s agricultural produce.
With its hand-baked finish, gentle sweetness, and use of several varieties of Kagoshima sweet potatoes, Satsuma Kintsuba makes a distinctive souvenir. It is also a way to enjoy the flavors of Kagoshima through a traditional Japanese confectionery technique.
When visiting Yakushima or exploring Kagoshima’s local specialties, look for Satsuma Kintsuba and enjoy the different flavors offered by its sweet potato varieties.
