Naruto Kintoki: Tokushima's Prized Sweet Potato, in Cakes and Sweets

Naruto Kintoki is a sweet potato variety grown in the sandy coastal fields around Naruto, Tokushima, where fast drainage and sea minerals from nearby tidal flats shape the crop. The result is a drier, denser potato with unusually high sugar content, reddish-purple skin, and pale yellow flesh. Harvest runs roughly from late summer into autumn, and the potatoes are prized enough to be sold as a named regional product rather than generic sweet potato. If you see 'Naruto Kintoki' on a menu, that's the specific variety being flagged, not just a description.

Because it holds its shape and sweetness well when cooked, Naruto Kintoki turns up in daigaku imo (fried and glazed potato chunks), baked tarts, soft-serve ice cream, and roasted whole as yaki-imo from stalls and trucks in the cooler months. Local sweet shops also fold it into steamed buns and yokan. Availability is seasonal and stall locations shift year to year, so if you're chasing a specific roasted-potato vendor, check current information locally rather than assuming a fixed spot or schedule.
