Where to Go in Osaka in September

Recommendation Rate: 

Autumn festivals are never deserted in Japan, and Kishiwada Danjiri Matsuri in mid-September is the most popular in Osaka, held in Kishiwada area. In addition to Osaka Castle, Namba Yasaka Shrine is also nice for an adventure of Japanese culture. Universal Studios Japan is kid-friendly to become the optimal choice for parent-kid tours. Abeno Harukas is a perfect skyscraper to see stunning sunset in the city, and Dotonbori and nearby Hozenji Yokocho are recommended for local food exploration.


1. Kishiwada Danjiri Matsuri is fierce like a racing. Its most exciting part is that men pull the 4-ton danjiri, traditional carts presented to the god, and rush across the street corners at full speed. It is quite dangerous when the cart passes through; please be cautious on your own safety when visiting.

2. On the watch of local weather forecast to keep your tour away from typhoons.
