Another theme park to explore is Universal Studio Japan which is located in Osaka. We have purchased ticket for USJ in advance thru online. You can check Klook for tickets if you want to buy in advance. Excited to visit USJ, I’m so looking forward to visiting the Harry Potter theme park, the highlight of our Japan trip. Since something came up in our hotel, I have to travel alone going to USJ, and my friends just decided that we’ll just meet there, packed with our ever reliable pocket wifi, I went on my own. Good thing I didn’t get lost hahahaha.. just like DisneySea, you can bring food inside the theme park, don’t worry there are convenience store and other food stall along Universal City.
