50 Best Japanese Restaurants near Diamond Bar

“Chicken Katsu lunch special is really great value. Spicy katsu sauce is the right amount of spice and flavor, and the salad dressing makes the salad pretty good. Taiyaki was made fresh and tasted great. Wish there was an option to buy less Taiyaki though; 5 is a little too much for even two people.“

“Not many places in LA offer hard to get fish from Japan. I was impressed with their unique fresh fish and the quality of sushi. I will definitely return for another great experience. I sat at the sushi bar and had great service from the chef.“

“Me encanto el lugar muy agradable el personal no se diga muy amables“

“Read my post it's the best around“

“This is some of the best sushi that I’ve ever had, and that’s saying a lot, because I spent many years living in Japan. The focus is on quality. It’s not cheap, nor should it be. You are paying for high-grade, quality, and freshness that is hard to find, especially in this area. I tested them out with the few items that you see pictured here and I’m definitely going to use them for an upcoming dinner party. I really like having an option like this available in Diamond Bar. There is really nothing else like it, honestly. Will be back again soon.“

“The food is very good and prepared fast. Good portions as well. I think it's the biggest cali roll I've had in a bento box. The popcorn chicken is too spicey for my baby pallet though. And the teriyaki sauce is salty. And the music was awful when i was there. Thats why the 1 point deduction fornatmosphere. But overall, I wish I loved closer to this place, I would eat here all the time.“

“Came in on a Friday night, found them through some positive google reviews and did not disappoint. The bowls and portion sizes are very generous for what you pay and most importantly food is fresh/delicious. The owners and staff are very friendly, very much looking forward to coming back weekly.

“Friendly and amazing owners. Food is wonderful“

“It was so good worth it y’all!“

“Food is delicious 😋 and service is great 😊 we are going back again soon 😃“

“Excellent service and food! Our family are regulars there and we joined them for lunch and had a delicious meal. Shout out to Abel and the entire lunch crew. You all were wonderful especially with our large group (including babies). The ramen, various sushi rolls, tempera, asparagus appetizer, miso soups and rice were all excellent and full of flavor! Highly recommend! Excited to go back. Oh and would love to see a vegetarian broth option for the ramen if ever possible! That would be an awesome addition. Thanks again!“

“The service at little Tokyo exceeded all expectations. The staff was not only knowledgeable about the menu but also displayed a genuine passion for the culinary creations. They were attentive without being intrusive, and their recommendations were spot-on. Special dietary requests were accommodated with a smile, adding a personal touch to the dining experience. The pacing of the courses was perfect, allowing us to savor each moment without feeling rushed.“

“It couldve been because I was early, dining in and the broth didn't develop a bitter after taste from over cooking, but it's been awhile since I've had good ramen. The champion ramen had a good mixture of wet and dry flavors. Chashu + seaweed had a subtle fish dry taste vibe which is new. Noodles were chewy and not clumpy mouth feel. Broth and ground pork were rich but not overly. Overall taste + texture was superb and especially warming during the winter. Also the waiter Rick is such a homeboy and service is amazing.

Last time I liked having ramen was when I was running around in an orange jumper. Hope the guys and gals stay in business.“

“Food was amazing! Tried the chefs combo(turns out the chef I had was also the owner) to which every piece of sushi had a good portion of their choice on top. Miso soup was good and tried their double salmon roll special. Very flavorful and good portion on the inside and out. Place inside is small but doesnt feel cramped, servers and chef are hospitable and ambiance is calm. Great for a date or even just to relax. Definitely returning!

Edit: Have returned numerous times and never disappointed. Pictures included“

“Good food and good service“

“It’s a really cute and homey atmosphere. Imma take my friends here someday. They got a few good ramens and they got vegan options as well. They got good dessert options too. Some steamed custard buns that look like little piggies. Come give it a try and give them some business.“

“I had a great experience at this ramen place! The broth was rich, flavorful, and perfectly seasoned, and the noodles had just the right texture. The toppings were fresh, and each bite felt comforting and satisfying. The staff was friendly and attentive, making sure we had everything we needed. The restaurant itself was clean and cozy, creating the perfect atmosphere to enjoy a warm bowl of ramen. I’ll definitely be coming back and recommending it to friends.“

“If not one of the best sushi 🍣 bars in Southern California or is the best in Southern California if you are ever in the West Covina San Gabriel Valley area it's a must stop and check it out the owner is so sweet and if the same sushi chefs one of the most premier chefs in the business I consider myself a condasuer now in sushi try the Javier roll and for the begginers in trying sushi go for the lobster roll u won't regret it well it will pinch your wallet u Will definitely enjoy the meat“

“The meat Quality is good, coming from someone that really doesn't know Wagu.we got the platinum tire, It was tasty, but we came looking for KOREANbbq, and they are not. Portions compared to a KBbq are minimal. You can order more and more, but it's bite size compared to what a KBBQ would give you. The side dishes are ok, little different then we're used to. I know it my fault for not reading more and noticing they are Japanese not Korean.
You can order 5 meats at a time, same with sides, and get 90 minutes to eat.
Meat Quality, good
Service, attentive
Price , ok for the quality but not the quantity.“

“Excellent sushi! We found this place using Google reviews and were not expecting it to be so good. The fish itself was high quality and handled well, and it seems like they make their own wasabi and pickled ginger - both were super fresh and did not taste like they came pre-packaged. The service was helpful and welcoming. I cannot recommend this place highly enough, it may be some of the best sushi I have ever had.“

“Saw this place while looking for thrift stores to explore. My boyfriend and I decided to go in and it was a great choice! Nice, quiet, with very friendly staff. Waited such a short time for the food and it was soooo good. Would definitely come back if I’m ever in the area again :)“

“nice little place... friendly staff... good food.“

“Midoh is one of those spots that instantly feels like comfort food done right. If you’re craving Japanese homestyle cooking—the kind that’s warm, hearty, and hits you with that “ahhh, this is exactly what I needed” feeling—this place delivers every time.“

“The service and food was super good. One of the best Ayce sushi spots I’ve had. I would call myself a sushi connoisseur lol and I give it a 10/10. Fish quality was there and they even gave complimentary ice cream at the end. I recommend getting the premium menu if you truly enjoy sushi, it is worth the extra 10 dollars. The oyster is a must try!!“

“Had the opportunity to enjoy a delicious meal at a Naruto ramen–themed restaurant, Ramen Ichiraku, and it was such a fun experience 🍜✨

The moment you walk in, you can feel the Naruto anime vibe—from the wall art to the neon characters, it truly feels like stepping into the show. The atmosphere was cozy, lively, and perfect for anime lovers.

The food did not disappoint at all. The steam pork ramen was rich, flavorful, and had lots of seasoning and toppings bamboo shoot, red ginger, corn , mushroom etc. , and you can tell why this place is well known for its Naruto-style ramen. We also tried the squid tempura and vegetable tempura, which were surprisingly very affordable and absolutely delicious—crispy, light, and perfectly seasoned. Next time I want to tried shabu beef ramen and onigiri tuna mayonnaise ( 6 rice ball wrap with crispy seaweed)
With seaweed)

Everything we ordered tasted amazing, and the portions were satisfying. Great food, great vibe, and such a fun experience overall. Definitely a spot worth visiting if you love ramen, anime, or just good comfort food 🍜💛“

“Best 🍱 sushi, best service, #Lynnandherfathertraditionenoughsaid. Cubi“

“Every dish was delectable, and great service! We all had a fantastic time there! Definitely will be back, and for celebrations.“

“Tasty ramen and fried rice. Takoyaki was so good we almost thought it was freshly made. Stir fry vegetables good too. Run by Japanese operators. Service and food was prompt on a busy weekday lunch hours. Oh, and I love their beautiful Japanese ceramic plates.“

“I order takeout from here all the time because the food is very very very good. The service is always very excellent My only concern is where it's located. I usually get delivery because I don't like the location of where this is. If it wasn't located where it is I would definitely be going there quite often. But if you know anything about this location you know what I'm talking about. But I do keep them busy with delivery I'll tell you what.“

“Great place!! The food is amazing and is such a fun place to have a birthday dinner! I have been coming here for so long and it never disappoints. The service is amazing with the cooks giving a little show! The place is a bit small, but they make it work! I love the vibe inside and now how they seat outdoors since the place is so popular! 1000/10 recommend“

“I went here about 10+ years ago. We didn't like it at all. Recently I went with a buddy. It was fantastic. Rolls are great. Large cuts of sushi. Great quality. I've already returned for another visit. New favorite sushi place“

“The owner is very sweet, attentive and so polite she is fast and always ready for you when you order with a smile and the food is awesome and she makes my experience better. Since my first experience she has been amazing I come back even by myself and she is the best I definitely recommend this place to for dinner with the fam. Or friends!“

“We went on a Friday night on a date and sat at the bar and had an amazing time. Not only was every food item fantastic Ethan was also a great server and chef offering great recommendations such as the chutoro moo which made my partner’s favorite and the Nikkei bluefin tuna which was mine. It was an awesome time with amazing food and thank you Ethan!“

“I really enjoyed eating there The food is fantastic The owner is just really a great guy and the staff is very accommodating although our server was a little off that night from what she normally is generally speaking we never have a problem there“

“Saw a picture of the Yakisoba Katsu sandwich and I had to have one! It was awesome! The Katsu was crispy and the meat tender. In short it was perfect! (not dry at all!) the yakisoba noodles was a nice addition as it absorbed the tonkatsu sauce and the cole slaw dressing! I also loved the brioche bread! A perfect touch. The sandwich was delicious and not like anything I have tasted before! This with a side of the curry fries! (YUM!) I'll definitely be back for more!“

“Located right next to Cal Poly college, Jinza Teriyaki is a great spot to eat after classes, my all time favorite is the Loco Moco bowl. The people are incredibly nice and especially early the place is a nice quite area to eat in. My only wish is that they would open earlier as someone who's out n about by 7am, but I understand not wanting to open at the crack of dawn.“

“This was extra special day Mama time sweet day! because it was our mama time while the kids were in school—a chance to slow down, catch up with a friend, and enjoy a peaceful meal together. We loved this cute little corner we discovered in Walnut. The space is cozy, clean, and thoughtfully arranged—perfect for relaxing and chatting without feeling rushed.

The owner was incredibly kind, welcoming, and polite. The hospitality really stood out and made us feel at home.
Delicious small bite & beautifully prepared dish! We tried the mini yubu sushi, which were fun, flavorful, and perfectly portioned for sharing.
The donburi bowl with seared salmon was so good—fresh, satisfying, and beautifully balanced. We also enjoyed the sweet shrimp & tobiko combination, which tasted very fresh and light.

Everything felt small enough to sample more, yet still filling and satisfying. Wanted to tried 9 yubu sushi. Owner said stop tried 4!! Too much food for beautiful ladies to handle LoL 😆 it is true. Honestly, we wanted to try even more items, but our stomachs were already full!

Looking Forward to Trying More Next Time😋

There are so many items on the menu we’re excited to come back for—especially the specialized sushi selections and the Chef’s Combo Rice Bowl. This is definitely a place worth returning to when you want thoughtful food, a calm atmosphere, and friendly service.

Such a lovely spot for a casual meet-up, a quiet lunch, or foodie exploring. Just a recommendation bigger tables for people who want to order more food and for bigger group size. The only suggestion I would appreciate so I can bring more friends over. Next time I’ll try different drinks. I thought mine was a little bit sweet. With mango and matcha tea.
Highly recommend — we will absolutely be back!“

“this place is bomb.!! and the service is incredible..“

“Excellent foods and excellent service every time“

“Authentic Japanese restaurant! This is a hidden gem in Anaheim area.I tried Live halibut, amaebi, uni, tempura.Food was excellent and owner was super freindly! Their kindness made me comfortable and enjoy my dinner!If you are looking for good sushi/sashimi place in Anaheim, this place is a must.This is a place run by Koreans, and it’s my first time eating proper Japanese food in a long time!The fish is fresh and well aged, so it's really delicious to eat.I think I will come back again when I go to Anaheim.“

“Friendly waters and comfortable setting“

“ok I was craving Cali rolls but my usual spot wasn't taking orders at the time on Uber eats. so I looked for another spot. I settled on this one because they had some good deals going plus the Cali rolls looked really tasty in the pic lol. I got 2 orders Cali rolls and a yellowtail roll. I also asked for teriyaki or eel sauce on side . everything was fresh and when I say the avocado and meat melted in my mouth .. it was so amazing . I will definitely be ordering again and trying some other rolls my fave. yellow tal isn't my favorite for sushi but I'm glad I tried it and it was very fresh .

ps.. I poured sauce on the rolls they didn't come like that lol one pic is the yellowtail roll and other is all the rolls together .“

“Worth the wait“

“Been craving teriyaki bowls lately. Decided to stop in and try this place out. The portion was good. Tastes was good. Price was competitive. Place is decent. Would recommend if you crave teriyaki chicken and are in the area. They have plenty of options to choose from.“

“Ok, let’s start with the beer. Sapporo on tap, in a frosty mug !!!! Super cold!!! Best beer I’ve had at a restaurant!!!!
Next the food, I got the chicken soy ramen on recommendation of the server. Great kinda sweet soy flavor. Ramen was perfect, soft but firm.
Wife got the tonkatsu ramen. Broth had rich flavor, again noodles perfect.
Tried this as a new spot.
Definitely will return.
And recommend!!!“

“The take-out box was convenient, if not finished in restaurant. The beef and chicken were great with the provided salad dressing, rather than the teriyaki sauce. It was placed as side as suggested by the host, especially that I was a diabetic. The water was refilled as needed, which was appreciated. I also asked for a second bowl of miso, which I enjoyed. Overall, it was great to have a meal at the Bento Box in Chino.“

“Everything their soup is delicious“

“my 1st time. food was off the hook good. I will be back again“

“The Kobe stakes is so testy . Assassins was as“

“Think that the last time I came here was in 2013. What can I say, time flies fast.
Ordered a medium lamb combo, and a medium ribeye combo. For the side, we also ordered chicken karaage.
Quality of both lamb and ribeye is good. The portion of the combo doesn't get me full, but is enough.
Service is prompt and friendly. Will definitely come back soon.“
