The hotel is relatively close to Osaka Station.
Take the JR Osaka Circle Line from Osaka Station to Universal City Station (ユニバーサルシティ), and then go to Universal Studios.
If you miss the flight, there is another route: take the "Yamatoji Express" from Osaka Station to Nishi-Kyujo Station, transfer to the JR Sakurajima Line to Universal City Station (ユニバーサルシティ), and then go to Universal Studios .
As the two most famous theme parks in Japan, there is Tokyo Disney in the east and Osaka Universal Studios in the west. If Disney is the most dreamy paradise for children, then Universal Studios is the favorite utopia for adults. Whether you are a movie fan or a simple tourist, you can always find the place you want here.
The performance time of "One Piece Water Battle" can be seen directly on the official website of Universal Studios Japan in the area near the entrance of the park. Therefore, according to the performance time and my personal experience, it is a little early Arrive at the performance site at one o'clock and get a more advantageous position. If you want to see your favorite characters up close, then please go and sit in front.
But... if, If you don't bring a raincoat, there may be some "little surprises" in this location. Near the second half of the performance, water will start spraying from the direction of the stage.
Although, this is not as good as it is. For the two performances I will talk about later, the "water spray volume" can be regarded as drizzle, but if the bag you are carrying is afraid of water, or you don't want to be watered, you can also go to some locations on the side.
