BEWARE!
Ichiza was shut down by the South Nevada Health Department on June 30, 2014, for the fourth time in four years. That is unacceptable. They were tagged with 38 demerits from 10 different violations ranging from handwashing issues to proper temperature for stored foods. Beware, especially since they are serving uncooked food.
As far as the food and service goes, the okra-natto was interesting, albeit slimy (but it's supposed to be), the sushi was good and the service was good. But if I had read about their sanitary issues, I wouldn't have gone. You can Google it, if you want to read for yourself.
