We recently visited Universal Studios Japan on a Monday, as expected the park was crowded, but it didn't detract from the overall experience. We were able to take 5 rides including the two new rides at Super Nintendo World. The experience was fantastic, I highly recommend getting a time entry ticket for Super Nintendo World through the USJ mobile app. The merchandise in Super Nintendo World is definitely worth buying, you can find some great souvenirs at affordable prices. Overall, we had a great time and we will definitely be returning to USJ the next time we visit Osaka.
