Endo Sushi is a family-owned sushi restaurant that has been around for over a hundred years and is situated perfectly right next to/inside a wholesale market, Chuo Ichiba (Marketplace). Decided to visit this particular spot because it came highly recommended on Google Map (4+ stars and over 1000 reviews!), and it absolutely met my expectations.
When you enter the shop you'll either be given a menu or you'll be directly asked if you want "omakase" (chef's choice); The sushi (primarily nigirizushi style, where the fish is placed on top of a cluster of seasoned rice) comes in a set of five with fish/seafood that is currently in season. When I visited, I had the hamachi (yellowtail) chu toro tuna, tai (seabream), uni (sea urchin), and anago (salt-water eel) (i.e., Plate 1 from the menu pics posted by other reviews on Yelp). The sushi was, in a word, delicious. Everything tasted so fresh, the slices of fish were THICC and so tender--I feel comfortable saying that this might very well be some of the best sashimi I've ever had, anywhere. Standouts included the uni--so buttery and generously portioned--and the tai--very chewy and plump.
One plate will run you about 1300 yen, and it's another 300 yen + tax for the aka-dashi miso soup. Supposedly their menu lists four different plates featuring different assortments of nigirizushi (see other reviews). You can also ask the staff to omit wasabi/inform them of any dietary restrictions you may have. And speaking of staff, they were very friendly, attentive, and welcoming, greeting each customer as they came in and went, and overall the store had a very cozy, quiet, and clean atmosphere. (Careful COVID measures in place as well.)
It's worth noting that the store is a little tricky to find at first. It's not very obviously positioned, so just walk straight through the main gate of the marketplace into the parking lot, and you'll spy a little island with a few restaurants smack in the middle of the parking lot (the restaurant is outside of the covered area with the vendor stalls). Also, Endo Sushi is open for business primarily in the morning (6:15am-ish to around 1pm). If you come around noon, expect crowds; I visited around 9am on a Friday morning and was lucky to find no line and few customers in the shop. So plan accordingly!
TL;DR: Rise and shine and come here early in the morning for incredibly fresh, thick slices of seasonal sushi at very reasonable prices.
