Uogashi Nihon’ichi

all day dining section with a sushi spot
pre-​cut pieces. not the top for the area but great for an airport

魚がし日本一 is the only sushi restaurant in the post security area of International flight and is opens ²⁴⁄₇.
I did have a high expectation as this sushi bar supposed to receive their seafood fresh daily from Tsukiji Fish Market.
My Nihonichi Nigiri (1500 Yen) did have a good selection of fish including Chutoro (medium Fat Tuna) and Hokkaido Scallop. But some of the fish were mushy tasting and did not taste fresh at all! The shiri rice balls were a little too big as a one bite sushi.
The green tea was really good that came complimentary with the order.
Just maybe if you are not on a layover like I do or you have a lot of time, it might just worth your while to leave Security area and try out other restaurants for some good sushi. And if you were stuck here just like me, 魚がし日本一 might do the job.
