4. Okonomiyaki
This Japanese savoury pancake is a popular dish throughout the country, but there are many different regional variations. The base ingredients most often used are flour, water, eggs and shredded cabbage, but other ingredients and toppings will vary. From vegetables and pork belly to octopus and squid, you’ll see all sorts of variations. In some restaurants you may find that tables are fitted with hotplates so you can cook your own okonomiyaki. In Hiroshima the ingredients are layers, whereas in other areas they’re mixed into the batter like a frittata or omelette.
