Not sure if this place is Japanese-owned, but all the employees and cook were Japanese.
I usually try to hit up some Japanese restaurants when I travel for work to see what it's like in other parts of the country. I wasn't expecting an authentic restaurants in Las Vegas (i.e. tourists eveyrwhere). I came across this place on Yelp and I was very impressed.
Not an izakaya, but you sure have your choice of appetizer items. I just sat at the bar and ordered about 3 appetizers for myself and I was stuffed. There is one cook at the counter who grills, cooks, and prepares the sushi platters. Shishamo (don't see this often on menus), Agedashi tofu (not used to this style but it was tasty), and Wakame Salad (too large for one person) were the items I ordered. I would definitely come back here again - if I had a car. If I recall correctly, it wasn't exactly walking distance (it was also 110 degrees).
