The ride itself is pretty similar to the US versions. What really stood out to me here was the story and the decor. The outside of Mystic Manor was really stunning especially at night, and the queue inside was also very immersive. What I enjoyed most, though, was the story: essentially, from what I could gather (the pre-shows are in Japanese), this really rich New Yorker goes around the world stealing artifacts, much to the anger of those cultures. Eventually he steals a cursed artifact and it bites him in the butt (I don't want to say more, as it could ruin some of the pre-shows).
Some might say the ride is similar enough to give this a miss while in Tokyo, but I loved it and really got in to the non-Twilight Zone story, and rode it multiple times.
