My friend Yuko Mizuno remembers having easy access to sweet potatoes during her youth in Tokyo.

“We had this roasted sweet potato man, a street vendor who would come around the neighborhood with stone-roasted sweet potatoes,” she recalled. Warm and sweet and nutty — “kind of homey,” Mizuno said — satsumaimo was a delicious treat on a cold day.

She was a bit shocked when, after moving to the States in the ’80s to attend graduate school, she tried American sweet potatoes for the first time. They were just too orange, too mushy, too fibrous and not quite sweet enough.

“It was like, ‘Huh, this is potato,’ ” said the Decatur mom, remembering her surprise.

One might have to wait a long time for a vendor to swing by a metro Atlanta neighborhood, but the sweet potatoes of Mizuno’s childhood can be found in specialty markets. They’re worth the search. Simply called Japanese sweet potatoes, they have a creamy, mellow taste reminiscent of chestnuts.

Whole Foods and DeKalb Farmers Market carry Japanese sweet potatoes, as do some specialty groceries. A few local farmers grow Japanese sweet potatoes, so if you subscribe to a community-supported agriculture group, you might discover some in your weekly box. Japanese sweet potatoes are shaped a lot like American sweet potatoes, but their skin is red, and their flesh is golden.

In Japan, sweet potatoes are a common ingredient in tempura and some pastries, but they also can be enjoyed in just about any recipe that calls for American sweet potatoes. Roast them, deep fry them like french fries, add them to vegetable medleys or soups (Mizuno suggests dicing them small and adding to miso soup). They can also be diced and cooked with rice.

Or you can cook them like Mizuno does: “Usually I just microwave them, just like you would a baked potato,” she said. “That’s the easiest.”

Chestnut Rice With Japanese Sweet Potatoes (Satsumaimo Kuri Gohan)

Hands on: 5 minutes Total time: 25 minutes Serves: 4

Although this take on a traditional autumn dish makes a great lunch or supper all by itself, the nutty-sweet flavor also makes it a nice complement to roast pork or turkey. The recipe easily doubles.

Ingredient notes: Japanese sweet potatoes are mellower and less fibrous than their American cousins, but you can substitute regular sweet potatoes if you can’t find Japanese. Cook and peel fresh chestnuts, or buy vacuum-packed cooked chestnuts. (Look for Melissa’s brand peeled and cooked chestnuts in the refrigerated area of the produce section.) Mirin, a sweet rice wine used for cooking, can be found in Asian markets or in the Asian section of many grocery stores.

1 cup sushi rice or short-grain white rice, rinsed

1 to 2 shiitake mushrooms, stems removed, chopped

8 to 10 chestnuts, cooked, shelled and halved

1 (8-ounce) Japanese sweet potato, peeled and cut into 1/2-inch cubes

1 tablespoon mirin

1 teaspoon soy sauce

1/4 teaspoon salt

In a saucepan, combine 1 cup water with rice, mushroom, chestnuts, sweet potato, mirin, soy sauce and salt. Bring to a boil, then reduce to a simmer, cover and cook 12 to 15 minutes, until the liquid is absorbed and rice is tender. Remove from heat and let rest, covered, 5 to 10 minutes more, until sweet potato is tender. Taste; adjust seasonings. Fluff with a fork before serving.
