I think this is one of the most authentic Japanese restaurants in San Jose. The sushi is excellent and the entrees have a true Japanese flavor and technique. Every time I go, there are always a couple tables with Japanese people. They also play Japanese pop music constantly, which adds to the feel. They also have Tepanyaki, although I've never ordered it.
The only weakness is the dessert, they only offer ice cream, vanilla, green tea, and chocolate. This really leaves you craving a true authentic Japanese dessert.
Service is AAA.
