Thanks for the update Jeremy. We are aware about Thunder Dolphin, and it's not even on the trip itinerary. That's great to hear about Fuji-Q, and I hope we get as lucky. The funny part about your story is it makes that park even MORE like the Magic Mountain of Japan, in that the park can't handle crowds at all, but on a light day you might actually be able to have some fun!
Thanks for the shout out at Mitsui.
