East Coast US to Japan supersonic? This is the stuff of fantasy. With the insanely high fuel burn and very small aeroplane body size, where are you going to put all the fuel for a trans-Pacific flight? NYC<->LON was already nearly the limit for the Concorde. As I understand, they had high priority when landing due to low fuel.

Interesting, I hadn’t realized the range was so short. I guess if they did trans-Pacific it would mostly be limited to Seattle to Tokyo, or routes with a stopover in Hawaii.
