I've lived in Japan for six years, and lived among Japanese Americans for far longer. I know authentic.
After some truly terrifying ethnic food experiences around here, this place almost had me weep tears of joy. The menu was the most authentic I've seen in the area (N.B., you will not find either a "volcano roll" or a "California roll" in most sushi places in Japan), and the food did not disappoint. The little gift shop, complete with Japanese American crane mobiles, reminded me of Little Tokyo (L.A.). I usually get the saba shioyaki (broiled mackerel). The ginger pork, nabeyaki udon (thick white noodles with vegetables in an iron pot), and ramen (real ramen, not the instant stuff) are also very good. They even have ramune (Japanese soda served in a distinctive glass bottle sealed with a marble). These folks know and care about Japanese food.
Their new location in Solon is also quite nice. They have big windows that let in lots of light, and the decor is both authentic and tastefully light.
You can find better Japanese food in bigger U.S. cities, but for Cleveland, this is about as good as it gets. Good enough for me to trek back next time I'm hankering for Japanese food.
Pros: Authenticity, relatively tasteful decor
Cons: Somewhat isolated location
