Some of the Japans biggest shipping companies (I’ve personally only used Kuroneko Yamato; but I’m pretty sure others do this too) will pick up your luggage from the airport, and deliver it to your room for ~15 USD per bag.
This also works in reverse, and even between cities — don’t take your heavy bags on Shinkansen, have a concierge or front desk ship them to your next hotel.
The Google keyword for this are ta-q-bin/takkyubin.
Trains are great in general. They also tend to be a poor fit for anything much more than carry-on. I've done it and managed but it's better not to if you can.
But Japan is the kind of place that people want to bring a whole lot of stuff back - I know a lot of people who basically fly out with empty suitcases and just fill them to the brim with random tchotchkes over here — and hey, whatever makes them happy.

And it's a bit stupid because the stations before and after the airport are the normal cheap price.
It’s Japan. Obviously I knew about the train lol. Their trains are awesome!
Took the bus back from the hotel.
Given how far NRT is from Tokyo, $200 doesn't seem too bad...
You'd be an idiot to use a taxi.
Or it's some exceptional situation (flight super delayed?)
Many travelers will just grab a ticket that sounds vaguely correct and then fare adjust at the end. Grabbing an IC card or one of the apps is the easiest course for virtually everyone though.
