We stayed in Osaka for 3 days because I wanted to primarily shop in Osaka! Ha! We loved Osaka, and sure will you! Osaka has a great night life and food in Dotombori, Minami (Namba District), the Instant Ramen Museum, Shin Sekai (entertainment district), Umeda Sky Building, the Osaka Castle. Osaka is also a busy city like Tokyo and a fashion capital. If you like lively evenings, head to Namba District or Dotombori. You will find scotch and wine bars and night clubs too in these areas.
