Seriously... BUY YOUR TICKETS IN ADVANCE!

Just got back from Japan and we had a day with not much to do so we decided to go to Universal Studios. We booked our tickets with Klook.com (US$59 per person for the E-Ticket), which ended up being the best decision we could've made because when we got there, the lines were extremely long. Some people had been waiting for over an hour. However, we didn't have to wait at all. Got our e-tickets from Klook and entered the park with no problem. After visiting Universal Studios in Florida, this park seemed a bit small, but it was still pretty fun. Especially the Harry Potter themed area. It is a great park, but if you don't have one day to spare and you've already visited a Universal Studios in the US, then you can skip it.

Inside the park the lines are still pretty long for most of the rides. So prepare your patience in advance, especially if you are visiting with kids.
