Explore neon-lit Dotonbori and try Osaka street-food classics; many restaurants open late 17:00–23:00 — good first-night atmosphere. Recommended: Kani Doraku for crab or a conveyor-sushi spot for variety.
Wander the historic streets of Gion, spot machiya townhouses and (with luck) geisha on their way to appointments; shops and teahouses usually open until early evening.
Visit one of the world’s largest aquariums, showcasing Pacific marine life; aquarium hours are usually 10:00–20:00 (check seasonal times) and it's stroller-friendly.
Choose from many casual restaurants and food stalls near the aquarium for sushi, ramen or set lunches; food court options open during mall hours (~11:00–20:00).
Return to Dotonbori for lively evening dining — try okonomiyaki (Mizuno) or kaiten (conveyor) sushi for a fun experience; restaurants often open until late.
