Top Things to Do in Osaka in August

Recommendation Rate: 

Fireworks show is the must-see across the country in August. In Osaka, annual Naniwa Yodogawa Fireworks Festival by Yodogawa River on the first or second Saturday in August is the most magnificent in that area. Osaka Aquarium Kaiyukan is a cool place to avoid summer heat and to see a variety of marine animals. Minoh Falls in rural Osaka is also a good site to escape summer heat, and Tombori River Cruise is a surprising way to appreciate the cityscapes.


1. You’d better book a seat for the Naniwa Yodogawa Fireworks Festival in advance. Meanwhile, there are many crowds near the venue, so it is recommended to go early on that day.

2. As the sunshine is strong in August, it is crucial to apply sunscreen cream and take on sunglasses as well as sunhat when getting outdoors.
