The ANA Business Class Lounge at Narita International Airport is much like the one in Haneda, except maybe a little larger.
I had a quick layover, and was able to spend about 30 minutes in the lounge.
The food spread in the lounge is very similar to Haneda as well.
There was sushi, onigiri, salad, miso soup, and chicken wings.
There is also a self-serve “sake bar”.
There is also a noodle bar as well.
The lounge does have showers available, but I did not have a chance to take a look during my quick visit.
