Tancho Japanese Restaurant

⭐️⭐️⭐️⭐️⭐️ 5 Stars – A Hidden Gem Worth Every Bite! We had an incredible Omakase experience at this unassuming gem in Castro Valley, and it truly exceeded all expectations. The service was a perfect 10/10 — the host was extremely attentive, warm, and made us feel genuinely taken care of throughout the evening. The food was exceptional — fresh, beautifully composed, and full of thoughtful flavors that worked harmoniously together. Each course felt intentional and elevated, showcasing top-notch quality without the pretentiousness. And the dessert? Unforgettable. The Hojicha panna cotta was an absolute standout — silky, flavorful, and the perfect ending to a phenomenal meal. Overall, this place easily gets 100 out of 100 from us. If you’re looking for amazing food, impeccable service, and

I had high hopes for this omakase place but it was maa maa (まあまあ) or just ok for $125 per person to sit down. It was way over priced for the cheap fish served.

The service was jama-jama (じゃま- じゃま) or over attentive; interrupting whenever, maybe to keep us on schedule. Atmosphere is fine if your on the counter but the tables have the next customers sitting there and staring. I would not go again and f

The sashimi at this restaurant is exceptionally fresh, and the service is outstanding. Chef Jeff crafts each dish with meticulous care—simple yet delicious.

Good omakase in Castro valley overall. Small restaurant with very attentive service. Focus on seasonal ingredients and more unique bites. Menu is interestingly half small plates and half nigiri which was different from what we saw on the reservation page which sample menu comprised more nigiri. I did read from recent reviews they might be changing things up. Personally really enjoyed the small plates which were unique with seasonal ingredients. Favorites there were: ankimo goma shiraee (creamy ankimo texture complemented the crunchy seasonal veggies), and donburi (overall just a huge fan of donburis and hotaru ika was in season). Nigiris were quite large, which I didn’t expect. I was initially worried that 6 pc would not be enough, but because of their size, it was. Each bite was quite f
