Tip: Osaka announces itself immediately through food and noise. The Dotonbori canal district — with its giant Glico Man sign and wall-to-wall neon — is the city's heartbeat, best experienced on foot with something to eat in hand. Ichiran Ramen's single-booth tonkotsu system, where each customer faces their bowl alone in a private cubicle, is one of Japan's most peculiarly satisfying dining experiences.
