Okonomiyaki Mizuno

Okonomiyaki Mizuno is the Dotonbori okonomiyaki counter that other okonomiyaki shops in the neighborhood get compared to — open since 1945, still run by the founding family's third generation, and a repeat pick for both the Michelin Bib Gourmand and Tabelog's "100 Okonomiyaki" ranking.

The dish to order is the one on the sign: yamaimo-yaki, Mizuno's own take on okonomiyaki bound with grated mountain yam instead of a flour-heavy batter, which keeps the inside noticeably lighter and closer to custard than the cabbage-dense versions found elsewhere in Dotonbori. It's cooked a few feet from where you sit — the room holds 38 seats split between low tables and a 12-seat teppan counter, and the counter is the better draw if you want to watch the batter poured and flipped rather than just eat the result.

None of that comes without a queue. Mizuno takes no reservations and runs strictly first-come-first-served; the wait routinely stretches past 30 minutes through lunch and into the evening, so arrive right at the 11:00 open, or well after the dinner rush, if you want to skip the line. Cash is always fine, and Mizuno also takes cards, though card payments carry a ¥3,000 minimum — worth knowing if you're ordering solo.

Worth flagging plainly: this isn't a kitchen built to flex around dietary restrictions. Every dish revolves around pork, squid, shrimp, scallop, octopus, or oyster, ruling it out for vegan, vegetarian, and halal diners outright. The signature yamaimo-yaki is a genuine outlier on the flour question — its batter is grated mountain yam with no wheat flour at all — but Mizuno runs no dedicated gluten-free menu, and the teppan is shared with flour-based dishes like the classic Mizuno-yaki and the noodle-topped Modern-yaki, so cross-contact isn't controlled for. Vegan, vegetarian, halal, and gluten-free travelers should treat Mizuno as a Dotonbori landmark worth admiring from the sidewalk rather than a menu they can adapt to.
