17 Best Japanese Restaurants in Fountain Valley

“Very good environment and food!“

“Everything was excellent! Service was top notch as well.“

“I cannot understand how Momoyama has anything less than a perfect five star rating.

We weren’t aware that it was single seating omakase as we happened upon this restaurant. We arrived an hour before their seating and they mention we had to make a reservation. We ended up getting the last one for the evening. We shopped around the area until it was time.

When we came back, the manager, Ryan, greeted us by name and guided us to our seat, even allowing space for my purse. There were seven total guests for the evening all seated at the bar in front of the chefs.

Ryan kindly introduced the chefs and everyone made us feel so welcome. He recommended the most delicious sake I have ever had, and continued to monitor our drink levels, refilling as needed. We didn’t need to ask for anything even once.

The food itself was one of the top three meals of my life, and I’ve eaten at many sushi restaurants, and Michelin star restaurants. As a fan of sauces and soy sauce, I was worried there wasn’t any offered, but each bite was so perfectly balanced I didn’t need anything else.

The pacing of the meal was appropriate, and I remarked how smoothly each dish came out considering this can be quite difficult with multiple parties and different eating speeds. But we never felt rushed nor like we were waiting on anyone.

The care and attention to detail was present in every morsel, every moment, down to the elegant quiet jazz music. Ryan and our chefs made warm chit chat without disturbing our dinner. We felt comfortable even with the high quality of food and service (which can sometimes make one feel like they need to “perform formality”).

The evening was the most delightful surprise and I can’t wait to go back. I will never stop recommending Momoyama to friends and visitors for the most elegant and delicious sushi in Orange County.“

“Dining at Tsuruichi Wagyu is an unforgettable experience for anyone who appreciates the artistry and flavor of premium Japanese beef. From the moment you step inside, you’re welcomed by an elegant yet cozy atmosphere that sets the stage for a meal that is both refined and deeply satisfying.

The star of the menu is, without a doubt, the Wagyu beef. Each cut is carefully selected for its marbling and tenderness, and the quality truly shines through in every bite. The A5 Wagyu was nothing short of extraordinary—rich, buttery, and melt-in-your-mouth tender. Whether grilled to perfection at your table or prepared in one of the chef’s expertly crafted dishes, the beef here is a masterclass in flavor and texture.

The Wagu experience is highly recommended for those who want to explore the full range of what Tsuruichi Wagyu has to offer. Each course is thoughtfully presented, highlighting the versatility of Wagyu in both traditional and innovative preparations. The pairing of sauces and sides, from the delicate ponzu to the house-made pickles, enhances the meat without overshadowing its natural flavor.

The service at Tsuruichi Wagyu is impeccable. The staff is attentive and well-versed in the nuances of Wagyu, providing helpful recommendations and ensuring that each guest’s preferences are met. The attention to detail, from the presentation of the dishes to the timing of each course, adds to the overall experience, making it feel truly special.

The ambiance is intimate yet sophisticated, making it an ideal spot for a romantic dinner or a special celebration. The combination of luxurious food, exceptional service, and a serene atmosphere makes Tsuruichi Wagyu a standout destination for any Wagyu enthusiast.

Overall, Tsuruichi Wagyu offers a dining experience that is both luxurious and deeply satisfying. It’s a place where every element, from the quality of the ingredients to the elegance of the presentation, is designed to celebrate the art of Wagyu. I highly recommend it for anyone looking to indulge in one of Japan’s finest culinary traditions.“

“Absolutely loved it here. The food was amazing. ❤️“

“Tony knows how to do it right... will recommend“

“Ordered a variety of items and my expectations were blown out of the water. I could not recommend this restaurant enough. As a very frugal individual, I would gladly pay anytime for this echelon of quality. If you are looking for a top notch Japanese grilling experience, this restaurant is THE best if not one of the best choices you could decide on.

The servers are also very nice, and the atmosphere is cozy. 10/10!“

“I went there for the first time I ordered 5 piece sashimi was very good and fresh ordered twice and delicious oysters omg 😳 and sashimi scallops was outstanding I give this restaurant 5 stars ⭐️ ⭐️ ⭐️⭐️⭐️“

“The best ramen you will ever eat anywhere. Great service. Great prices. Worth the wait.“

“So good and server are very friendly“

“Sushi Plus is a gem! The food is always fresh and delicious, and the customer service is truly something special. It has that small-town warmth that makes you feel like family every time you walk through the door.

As someone with celiac disease, finding a place that takes gluten-free dining seriously can be hard—but Karen, Yukon, and the whole team go above and beyond. They remember my dietary needs, take every precaution, and I have never gotten sick. I always feel safe eating here, and that peace of mind means everything. (Did I mention the food is DELICIOUS?!)

Thank you for your continued care, kindness, and amazing food! One of the favorite weekly meals with my husband. 😊“

“Good food, good service, okay atmosphere. Oh and good prices too! This is a local spot for me. I love customizing the spicy tuna roll to include cilantro!

My 2 gripes:
1) The specialty rolls are overloaded with sauces (I don't order anymore)
2) I wish they had a menu for making custom rolls (I always have to ask the server for my custom order)

Having to ask the server is more work and leaves prices/options ambiguous. Leading me to a more simple customization.

Parking: Parking all over.

Kid-friendliness: As kid friendly as sushi gets. It's not a place made for kids, but the atmosphere is conducive to bringing kids along.“

“Sushi Koto is always a treat for me. I love to come here for what I feel is the next best thing to eating in Japan. There is always a wait for Sunday brunch, but they do take reservations. Excellent service and friendly staff. This is definitely not your ordinary neighborhood Japanese restaurant. Highly recommend it!“

“Kobe Sushi is one of my favorite sushi spots for as long as I can remember. The Black Pepper Tuna roll and Sashimi platter are our top choices. 100% recommend!“

“Tasty food and nice place and very good price 😋“
