Tokyo, Japan
Now, this falls closer to the Mexico section of uncharted territory since the Vegas Golden Knights haven't been here, either. It's also the largest city in the world with 37 million people in its metropolitan area. Imagine having a huge following in Japan, where fans on the other side of the Pacific watch your hockey team.
That would be an epic sight to behold. But there's also the prospect of bringing a hockey game or hockey clinic to the Tokyo Dome. Mainly used for baseball games (specifically in the Nippon Professional League), the stadium would be ideal for watching the Golden Knights play an NHL game. Imagine Adin Hill developing a cult following in Japan by posting a shutout.
Also imagine Jack Eichel becoming a sensation by scoring a hat trick. That would catapult Vegas's popularity to new heights, making them a global sensation. With the team settling roots south of the border, they could also hop across the Pacific and settle in the "Land of the Rising Sun."
