Top Things to Do in Osaka in May

Recommendation Rate: 

During early May, the golden week in Japan, a variety of outdoor activities are held across Japan. There will also be wonderful activities at Osaka Castle, Expo Commemoration Park, and more spots in Osaka. Although cherry blossoms have fallen in May, other flowers are blooming in parks, which are also worth of viewing. Universal Studios Japan, Osaka Aquarium Kaiyukan and Umeda Sky Building are must-sees in Osaka, and visitors could also enjoy shopping and food exploration around Dontobori, Kuromon Market, and Umeda Underground Street.


1. Universal Studios Japan is quite large-scaled with several theme zones. If you have only one day there, please choose the zones, rides and activities you are most interested in, such as The Wizarding World of Happy Potter.

2. Umeda Sky Building is a prefect site for bird’s eye view of Osaka city and seeing splendid sunset. If you would like to enjoy the setting sun, please check the sunset time beforehand, and get there at least half an hour in advance.
