Truly. Even if you want to land in Tokyo (since lots of flight deals take you there or Osaka). Grab the Rail Pass before you fly in, then take the bullet train to any number of cities. You'll enjoy relatively low-cost travel thanks to the rail pass, and you'll get to see a bunch of cities that aren't as popular.
Its perfectly doable to land, activate Rail Pass and then move to your starting city by Shikansen on the same day. In 2019 we moved all the way to Hiroshima on the first day and stayed in Tokyo at the end for a couple days.
This order also very useful if you want to buy stome stuff, as usually Tokay has the best selection but you don't want to lug it all over Japan with you - best do the shopping at the end of the trip.
