Grilled corn on the cob brushed with soy sauce, miso, or butter — a classic Japanese summer festival (matsuri) and street food. The husked corn is grilled over charcoal until charred in spots, then brushed repeatedly with a savory glaze that caramelizes on the hot kernels. Eaten at summer festivals, fireworks displays, and beer gardens.
Yaki-tomorokoshi is a Japanese summer festival staple. The dish is simple — grilled corn glazed with soy or miso — but the cultural setting is the point: Japanese summer festivals (matsuri) feature food stalls (yatai) selling yaki-tomorokoshi alongside yakitori, takoyaki, and yakisoba. The dish emerged in the Showa era as a festival food, taking advantage of summer corn season. The Japanese name 'tomorokoshi' (or tōmorokoshi) is derived from Portuguese-influenced terms for the New World crop.
An ear of yaki-tomorokoshi is partially blackened, the kernels glossy with glaze. The first bite is sweet from the corn, then savory from the soy or miso, with a smoky char flavor in spots. The glaze caramelizes unevenly, giving each kernel a different intensity. Eaten hot off the grill, husk pulled back as a handle.
Yaki-tomorokoshi's flavor depends on the caramelization of the glaze. The corn is grilled over charcoal (preferred for the smoky flavor) until the kernels char in spots — the Maillard reaction on the corn's natural sugars creates nutty, caramel notes. The glaze (soy, miso, or butter, or a combination) is brushed on repeatedly during grilling; each layer sets and caramelizes against the hot corn, building up a savory-sweet lacquer. The glaze must be applied in thin layers so it doesn't drip off; the corn's heat is what sets it.
Variations
Shoyu-yaki (soy), miso-yaki (miso), and butter-shoyu (butter-soy) are the three classic styles.

Ingredients
Serves 2How it's made
6 steps · 5 min
- 12 min
Husk corn, leaving the stem as a handle; remove silk.
- 23 min
Make the glaze: soy with mirin, or miso thinned with mirin, or melted butter with soy.
- 36 min
Grill corn over charcoal, turning regularly, until kernels char in spots.
Watch outGrill over charcoal, turning often, until the kernels char in spots — that Maillard browning on the corn's sugars is the nutty-caramel base for the glaze.
- 43 min
Brush glaze on; continue grilling and turning.
- 53 min
Repeat glazing 3-4 times, allowing each layer to set.
Watch outBrush the glaze on in thin layers and let each set before the next — slather it thick and it slides off and drips into the fire instead of lacquering on.

Serve hot, eaten off the cob.
