The other half and I eat here fairly regularly and we love it. He's veg and I eat meat and we can both customize our meals the way we like them. Having spent time in Japan, my other half vouches for the food and approximated authenticity here. I don't know authentic Japanese cuisine per se, but I can tell you that a heaping bowl of tonkotsu, the size of my head and then some, definitely fills this big boy's belly every time. I've had the curry bowl as well as the noodles and all are excellent. The shrimp & veggie tempura are great as well and the sweet, dark dipping sauce that accompanies the fried delights also ends up in my soup, to boot. Color me addicted. The staff is young and knowledgeable, and have accommodated some very tricky dietary demands from friends of ours with very specific food allergies. Best of all, it doesn't cost us an arm & a leg for a hugely satisfying meal. Highly recommended gem of an Asian restaurant in Tempe AZ.
