Everywhere! The food is delicious! Osaka is a foodie paradise and has a lovely market where you can sample interesting cuisine. You’ll find Ramen bars dotting the streets in any city you go to with people standing up to slurp their noodles. Katsu curries, sushi, and soba noodles are also abundant.
Trying an Izakaya (an informal pub-type place which offers small tasting dishes) is a great way to experience local culture. The Japanese are passionate about their food and aim to find fresh ingredients. It’s hard to go wrong with the food!
