Okonomiyaki: Osaka vs Hiroshima, the two styles compared

Okonomiyaki is a savoury cabbage pancake. JNTO’s okonomiyaki guide describes two styles and sorts them by place: Kansai, with Osaka as the example, and Hiroshima. The Japan food guide lists the same two styles in its dish and region table, with Osaka style under Kansai and Hiroshima style under Chugoku.

Osaka style, also called Kansai style, mixes cabbage, flour and egg into one mix and griddles it. The toppings go on the griddled mix.

JNTO lists the toppings as pork, sauce, mayonnaise and aonori. Aonori is a green seaweed seasoning. The list tells you three things before you order:

• Pork is a standard topping, so the dish is not vegetarian unless you ask for a change, and pork matters for halal and pork-free diets.
• Egg is in the mix, which matters for an egg allergy.
• Flour is the binder, and JNTO does not say what it is made of, so ask if you avoid wheat.

Hiroshima style layers its ingredients instead of mixing them, and it includes noodles. Those two points set it apart from the Kansai style, per JNTO, and the noodles are part of the style, not an extra.

JNTO does not name the Hiroshima toppings, the noodle type or the cooking method, so this page does not either. If you avoid wheat, egg or meat, ask the shop what each layer contains.

Order the style of the city you are in, and choose between them by structure. If you want one mixed pancake with a pork, sauce, mayonnaise and seaweed topping, order Osaka style. If you want layers and noodles in one dish, order Hiroshima style.

If your route covers both cities, eating both is the simplest comparison, because the difference is in the build and the noodles. If it covers one, eat that city’s style. Osaka belongs to the Kansai region, which also holds Kobe Beef, and Hiroshima belongs to Chugoku. Both regions have a guide: Kansai and Chugoku.

Tell staff about diet and allergy needs when you book or sit down, before you order. JNTO says not all places show allergy information.

• Allergens. Japan’s mandatory allergen list for packaged food has nine items: shrimp or prawn, crab, walnut, wheat, buckwheat, egg, milk, peanut and cashew, added by the Consumer Affairs Agency’s notice of 1 April 2026; the label transition period is not confirmed. Egg is in the Osaka mix, and the flour or noodles may be wheat. The rule covers packaged food, and the agency’s page states no duty for dining out. The Food allergy card lists the nine.
• Fish. JNTO says fish stock (dashi) is a common hidden item in Japanese food. Secondary travel guides list bonito flakes on okonomiyaki and stock in the batter. Ask for no meat, seafood or animal products including dashi, and clarify chicken, pork and fish.
• Pork. Osaka style is topped with pork. JNTO’s Muslim travelers guide says halal-friendly restaurants may not have a separate halal kitchen and that mirin and cooking sake are common, so check ingredients.

Eating vegetarian and vegan in Japan has the longer list of hidden ingredients.

Pay the menu price: tipping is not expected, menus show tax-included prices, and eating in carries 10% consumption tax and takeout 8%, per the National Tax Agency (takeout rate: medium confidence). Cards are usually accepted at urban restaurants, but small shops and rural areas may be cash only, so carry cash. Tipping and paying in Japan has the detail.

Some restaurants keep a list at the entrance where you write your name, party size and seat type, and popular downtown areas often need a reservation; Ordering food in Japan has the steps. When you share a plate, take food onto your own small plate first. Never stand chopsticks upright or pass food from chopsticks to chopsticks.
