Like its big sister Tokyo, Osaka is the product of ancestral traditions and amazing technological innovations. And despite its size, its location on the Pacific Ocean give it a sense of serenity. The main historic landmark is the 16th-century Osaka Castle, which stands proud in the midst of majestic skyscrapers. The lively streets of Dotomburi and the bizarre Shinsekai district attract thousands of locals and visitors. A multitude of restaurants offer menus full of regional specialities: takoyaki, made with octopus, and other succulent dishes such as kushikatsu kebabs.
