14 Best Japanese Restaurants in Buena Park

“This place is truly a home style gem. They make everything themselves, from the kimchi to all the side dishes, and everything is so fresh. It is the spot I always crave after work. The service and the food are both excellent. Highly recommend!“

“Roll & Teriyaki is a good local spot for delicious, fast-casual Japanese food at affordable prices. The quiet and clean dining area will accommodate small groups or solo diners.

The menu boasts Japanese favorites that most people will be familiar with. The value-packed combos are a real treat. I've also enjoyed the chicken and beef teriyaki bowls, as well as the sushi and roll offerings. While they may not offer as many fish varieties as other places, the ones they do have are all fresh and satisfying.

For a small, mom-and-pop restaurant, I'm glad there's a place like this close to home and affordable. The service is good. I've visited many times and the owner is a man of few words. The other staff have been nice as well.

If you're on a budget and craving Japanese food, R&T is worth checking out. There is plenty of parking in the public lot.“

“Located in a small retail Center at Rosecrans and Beach Boulevard, the people are friendly and the food is delish. Plenty a parking for all including handicapped and bikes! Food is moderately priced. Go there, you won't be disappointed!“

“We ordered the Chicken Nanban and the Saba (Mackerel) both were delicious and full of flavor. Everyone was polite and we were served quickly. We will definitely be coming back to try their other dishes. Highly recommend!!!

You should also order Calpico Citrus drink to go with your meal super refreshing.“

“I had an amazing experience at the Kobe Gyukatsu restaurant. From the moment I walked in, the service was truly outstanding—friendly, attentive, and welcoming without ever feeling rushed. The staff went above and beyond to make sure everything was perfect, and it really made the whole dining experience special.

The food itself was exceptional. The gyukatsu was cooked to perfection—crispy on the outside, tender and juicy inside—and full of rich flavor. Every bite was satisfying and showed the care and quality that went into preparing it. Alongside the main dish, all the sides were fresh and balanced, complementing the meat beautifully.

One of the highlights of the evening was the matcha beer. It was unique, refreshing, and surprisingly smooth, pairing wonderfully with the meal. It’s definitely something I would recommend trying if you visit.

Overall, this restaurant combines excellent service with top-quality food and drinks. I left with a smile, completely satisfied, and already looking forward to my next visit. Highly recommended for anyone who loves great food and a warm, welcoming atmosphere.“

“Service was top notch tonight“

“This place is one of my favorite spots for pork cutlet. The food is always delicious, and the portions are very generous. You don’t even need a long explanation—it’s simply tasty. If you order the combo menu, you’ll definitely leave with a full stomach. The ingredients are fresh, and the presentation of the dishes is neat and appealing. Highly recommend!

It's been a long time since I ate at the restaurant. It's the best tonkatsu restaurant in the OC area. The price is reasonable, the combo meal composition is very good, and the quality of the food is also very satisfactory.

The thickness of the pork cutlet and the taste/dish of frying were all done very well.

I also praise the staff's quick and accurate service. All my colleagues who went with me praised the food.

I'm ready to open my wallet at any time“

“Food was really good! They have lots of interesting and adventurous choices. The presentation of the food was beautiful.

Everything is super clean!“

“6 / 1 / 2025 = 5 Star = Ist time to be here and order beef bowl togo , I do notice no saying Hi or any greetings, my food is great that's the main reason for this review , for the crew I think 3 star only , i will try again in the near future.“

“i like the food, big serving & it’s worth the price, i hope they willnot increase the price or lessen the service.“

“I've been here multiple times now, and it has consistently exceeded my expectations. One of the things I appreciate most is their late closing time. As someone who works the graveyard shift and starts their day much later than most, it’s often hard to find quality spots open past 9 PM. Ozen fills that gap perfectly — it’s become my go-to sushi place for late-night cravings.

No matter the time or day, I’ve always been greeted warmly upon arrival. The wait has never been long during my visits, whether on a weekday or weekend. The staff here is incredibly friendly, attentive, and efficient — they make you feel genuinely welcomed and taken care of.

The sushi itself is fantastic. Every roll is crafted with care and doesn’t fall apart easily, which shows the skill behind the preparation. The fish is always fresh, and the flavors are balanced and satisfying. Ozen offers two tiers of All-You-Can-Eat (AYCE) options: Regular and Premium. So far, I’ve only tried the Regular AYCE and have been thoroughly impressed — generous portions, great variety, and no skimping on quality.

Pricing is also fair, especially considering the quality of food and service. Compared to other sushi spots in the area, Ozen delivers great value without compromising on taste or presentation.

It’s a great place to come solo for a peaceful late-night meal or with friends to catch up over delicious sushi. Whether you're a night owl, a shift worker, or just someone who appreciates good food and good service, Ozen Sushi is definitely worth the visit.“

“Wonderful place! Staff is super friendly. I got a regular bowl with salmon and purple rice. The sauce was really good and the selection of toppings and fish. Highly recommend of you like poké

Vegetarian options: Its mostly fish so great for pescatarians but not for vegans.

Parking: Plenty of parking spots

Wheelchair accessibility: There is a ramp up to the door of the restaurant and the inside is pretty open too.“

“Lol! We are here every week and the owner always treat us like they never saw us!“

“I thought I knew what fresh fish tastes like. I did not 😂. I can say this was the best authentic, fresh fish restaurant I have ever been to. My partner and I ate so much food that we only stopped because we were too full. Everything was satisfying, from the service to the food. Our compliments to the Chef! I highly recommend going on an empty stomach for the full experience of the tastiest, freshest fish you will ever have. I want to thank the staff for offering to move us to a bigger table! The staff was so informative and also recommended what to pair each dish with. Thank you for this amazing experience! 🍣🐟❤️“
