Okonomiyaki is Japan's most democratic food: a thick savory pancake cooked on an iron griddle, filled with cabbage, protein, and a variety of additions, topped with sauce, mayonnaise, and bonito flakes. It is working-class Osaka pub food that became a national comfort dish. It is also the subject of genuine regional identity debate — Osaka's version is fundamentally different from Hiroshima's, and residents of each city will tell you theirs is superior.
The Osaka/Kansai Style
The original and most common style. The batter — a mix of wheat flour, nagaimo (mountain yam), eggs, and dashi — is mixed thoroughly with the fillings before cooking. This creates a single, unified disc with an even distribution of cabbage, green onions, pork belly, seafood, and whatever else you've chosen. The result is dense, moist, and savory throughout.
The batter-to-cabbage ratio is key: too much batter and it becomes gummy; too much cabbage and it falls apart. The best Osaka okonomiyaki restaurants have been refining this balance for decades. After cooking (4–6 minutes per side on the teppan), the pancake is topped with Worcestershire-based okonomiyaki sauce (thicker and sweeter than the Worcestershire you know), Japanese mayonnaise (Kewpie brand — richer than Western mayo due to the yolk ratio), and katsuobushi (dried bonito flakes that wave dramatically in the heat).
The Hiroshima Style
Fundamentally different construction from Osaka style, which is why Hiroshima residents insist they are different foods. Rather than mixing ingredients into the batter, the Hiroshima style layers them:
- A thin crêpe of batter is poured first
- A mountain of raw cabbage and bean sprouts is piled on top
- Thin pork slices are laid over the vegetables
- The whole thing is flipped to cook
- Yakisoba noodles are cooked separately on the griddle, then placed under the pancake when it's flipped again
- An egg is cracked and fried on the griddle, and the pancake is placed on top of it
The result is larger than Osaka style, more textured (the noodles add a distinct chew), and with a crispier outer layer from the egg. In Hiroshima, these are cooked by the chef; you don't grill your own. The main Hiroshima street for okonomiyaki is Okonomimura — a multi-story building with 25 different okonomiyaki restaurants.
Other Regional Variants
Monjayaki (Tokyo): The Tokyo variation — a runnier batter that spreads across the griddle and is eaten directly from the cooking surface with small metal spatulas. More liquid, more umami-intense, completely different texture from Osaka or Hiroshima style. The Tsukishima district in Tokyo is the headquarters.
Fuyaki/Negiyaki (Osaka): A thinner variation emphasizing green onions (negi), sometimes with beef tendon (sujinegi) for particularly deep flavor. More specialized, found at restaurants that focus on it.
Where to Eat It
Osaka
The Dotonbori area has multiple okonomiyaki restaurants; Mizuno (established 1945, in business longer than most tourists have been alive) is the most frequently recommended. The Shinsaibashi and Amerika-mura areas have newer, more casual options. Self-cooking teppan tables are standard — staff will start it for you if you prefer.
Hiroshima
Okonomimura (6th–8th floors, Shintenchi area) has 25 restaurants. The basement of Parco shopping center has additional well-regarded options. The correct behavior in Hiroshima is to say you prefer Hiroshima style and ask which restaurant does theirs best — locals have strong opinions.
Tokyo
Tsukishima for monjayaki (10 minutes by metro from Ginza). Standard okonomiyaki restaurants throughout the city; the Gindaco chain also offers a serviceable version if you need one quickly.
Cooking Your Own
Many Osaka okonomiyaki restaurants have you grill your own on a teppan griddle built into the table. This is part of the experience — the restaurant provides the bowl of mixed batter and ingredients; you pour, press, and flip at your table. Staff will demonstrate and check in on you. The main mistake tourists make: flipping too early (the underside should be set, about 4–5 minutes) and flipping only once.
