Osaka, Japan

Osaka's street food culture is captured in the Japanese phrase "kuidaore" — to ruin yourself by eating. The Dotonbori district dishes out takoyaki (octopus balls), okonomiyaki (savoury pancakes), and kushikatsu (deep-fried skewers) from hundreds of stalls, while Kuromon Ichiba Market has supplied Osaka's chefs with premium ingredients for 200 years.
