Just to be clear, I'm not anti international travel at all (at least in a non-COVID scenario!).
Getting to visit the Japanese parks is definitely something I eventually want to do (because Tokyo DisneySea looks like the best park on the planet for the types of attractions I enjoy the most, and USJ still has Jaws!), but with my travel dance card mostly filled for the next couple years (assuming next year gets back to a degree of normalcy through either treatments or vaccines), it's very likely not happening before Epic Universe opens.
