As one of the only Japanese markets in Las Vegas, Nakata Market of Japan stocks many Japanese products that can only be paralleled by the smaller shops in Little Tokyo, Los Angeles.
Certain things that I cannot find in Chinatown or even the various Asian/Filipino Markets around town can be found at this location. Things like (Umaibou) or (Okinawa Soba) that bring back many memories of living in Japan.
I do admit that this place can be extremely pricey, but that's with any grocery store really. You just have to know what you're coming in for. What makes it even better is that Nakata has a rewards/punch card that can save you even more!
