Yakimo: The Sound of Autumn in Japan

There is a sound that every Japanese person of a certain age knows by heart. A slow, warbling melody drifting through the neighborhood, followed by a deep voice: "Ishi-yaki-imo... Imo..."

It is the Yakimo vendor's truck. And when you hear it, you know autumn has arrived.

Yakimo—roasted sweet potato—is one of Japan's most beloved seasonal foods. Unlike the pale, starchy sweet potatoes found elsewhere, Japanese Yakimo (particularly the Beni Haruka variety) are slow-roasted until their natural sugars transform into something almost honey-like. The skin turns dark and crisp. The inside becomes golden, soft, and intensely sweet.

At our home in Kaizuka, we roast Yakimo the traditional way—using stones and low heat, the same method that street vendors have used for generations. There is no recipe. There is no rush. You simply wait, and the potato does the rest.

Autumn in Japan is a season of gratitude—for the harvest, for the cooling air, for the beauty of change. Yakimo is a small but perfect expression of that spirit. Warm in your hands, sweet on your tongue, and deeply, unmistakably Japanese.

If you visit us in autumn, we will make Yakimo together. And you will understand why this humble sweet potato has been warming Japanese hearts for centuries.
