If you intend to do a fair amount of travelling and your stay is <3 weeks, it may be worth getting a JR Pass[1]. It doesn't work for all lines, but does include the Shinkansen and several of the major inner-city lines. Buses too.

Probably not worth it if you're only visiting one city as the pass is quite expensive. There are regional tourist passes though.

Unfortunately the 70% price rise on the JR pass back in 2023 made it much less likely to be economic for most people compared to just buying tickets as you go, even for trips that visit more than one city. Last time I was there I did a loop up from Tokyo to Hokkaido and back by rail, and it was still cheaper to buy individual tickets. (There are obviously still some itineraries where it works out cheaper, but it's much less of an "obviously good idea for most people" than it was back before 2023.)

Having followed some tourists coming to Japan, a large amount of the people appreciate convenience, and the rail pass gives them that. The price is secondary.

Hell, there are even people paying the equivalent of 100 USD just to have someone pick them up from the Haneda airport and accompany them to the hotel. Not even a taxi service, just to be with them to buy them the train tickets, etc.
