Its a 6 hour flight vs a train ride at a max of 220mph, but max speed and average speed are different things. If you just went 220mph the whole way it would still take 13 hours but no HSR in the world actually averages anywhere near that. The Tokyo to Osaka Shinkansen averages around 150mph and that's among the fastest average speeds in the world. Realistically its going to take more like 19 hours. Its also going to cost more too because you have to pay staff for 19 hours of work, you have to burn more energy plowing through the thicker air at sea level, and you have to build and maintain all that expensive infrastructure in between.
The US needs a HSR line that connects D.C. to Boston though Baltimore, Philadelphia and NYC because its a bunch of highly populated and important cities close together in a straight line. Everything else beyond that gets questionable as far as US HSR goes. The US just really doesn't have its cities well laid out for HSR.
