50 Best Japanese Restaurants near Diamond Bar

“Ginkgo Katsu is a hidden gem for anyone craving crispy, flavorful Japanese katsu. The chicken and pork cutlets are perfectly fried — golden, crunchy on the outside, and tender inside. Portions are generous, especially with the bento boxes that come with rice, salad, and sides.“

“Read my post it's the best around“

“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“

“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!“

“We got the A5 Wagyu skewers and the Sushi platter. Sushi is fresh, beef is good. I would say that the atmosphere is more new generation pop themed rather than traditional Japanese. The service was great! Very attentive! The food tasted good but not exceptional. The rice was a bit pasty and the beef not as flavorful for an expensive dish. Karrage was great!“

“love this restaurant, even I am not a fan for raw food. I ordered beef and chicken teriyaki. It is good and delicious, and the service was excellent. Really want to recommend to friends.“

“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.“

“Good food and good service“

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

“Very friendly service. This place gets really busy on a Friday and Saturday evening and the staff handles it wonderfully. Food is also very good, one of a few places that serve kizami wasabi. Our favorites include the beef udon, energy roll and the sashimi platter.

Drink specials always on point. Plenty of parking.“

“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“

“We went on a Friday afternoon for lunch, it was not too busy.

We ordered the tempura udon and the pork cutlet, both were delicious. We ended with the matcha bouchee, the soft cookie cream sandwich and that was unique and really good as well. Will have to come back to try more dishes!“

“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!!“

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

“Came in on a Monday and the vibe was very calm. Server was attentive and quick to bring out food. Food tastes great all the way down to the miso soup. I got the chirashi and my partner got the bento box and we enjoyed the quality of the fish. Will definitely be coming back when around the area again“

“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.“

“Big bowl of deliciousness! Authentic ramen we've been searching for in the I.E. We had the Naruto chashu ramen with medium spice and everything about it was perfect.
If you're a Naruto fan, this is your spot. Anime themed decor.“

“Friendly waters and comfortable setting“

“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“

“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.“

“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!“

“This place rocks! You get so much food for the price and it is all so good. I especially like their gigantic california rolls, inari sushi, and their tempura. They have a plum wine that is dangerously delicious so be mindful!

The atmosphere is very retro seafood joint but in a fun nostalgic way. I love coming here with my husband and having a delicious (and budget friendly) date night.

They also have a loyalty stamp card so make sure you get your stamps!“

“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!“

“You came back hungry and got the perfect welcome — a spread that looks both filling and delicious. 🍣🥗

On the long plate, you’ve got a mix of sushi varieties:
• A beef-topped gunkan (ground or marinated beef wrapped with seaweed).
• A spicy minced topping, likely spicy tuna or spicy salmon.
• Grilled eel (unagi) with that glossy sweet soy glaze.
• Shrimp nigiri with a touch of sauce.
• At the bottom, wrapped in plastic, looks like a musubi — rice with grilled meat or spam, perfect for later.

On the side, a fresh salad with crisp lettuce, cucumbers, cherry tomatoes, and dressing — and best part, it’s unlimited. 🥗✨

By the last picture, you’ve also got a dipping sauce ready and a sushi roll off to the side, so you’re set for a feast.

If you walked into this starving, that first bite must have hit the spot.“

“Found this place randomly searching for a local Japanese style restaurant and found this Gem. Tried their Chicken Curry plate as it seemed to be there go to with their BOGO promotion. The curry had a phenomenal and savory taste. I'd recommend Level 3 Spice level as it is a great blend of flavor and spice. If you're interested in having great Japanese Curry this is the spot. I also tried their potato croquette which was exquisite I ate it immediately and took a photo part way 🤣 into eating. I also have their Strawberry Matcha Latte which was a great blend and tasted perfect. Definitely coming back to try the Curry Omelet variety. This is a great spot to come with friends or if you just want to enjoy some great Japanese food solo.“

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

“I had delicious sushi here today for the first time in a while. All the staff were very friendly. The fish was fresh and tasted great. The tempura was perfectly crispy, and the salad dressing was excellent.

Also, having the Green Tea Honey Yuzu Tea with the meal made everything taste even better. I’ll definitely be coming back!“

“Excellent foods and excellent service every time“

“Wow this place surprised me so much, I went on my birthday it was a Thursday mid day and it was lonely. Not sure if that’s good or not but as we walked in, we were greeted and welcomed to a nice beautiful atmosphere.

Open concept, nice design. We were serviced beautifully everything was clean and squeaky clean floors.

Menu was okay to read, but we were able to order a few yummy rolls.
Ocean roll
Super salmon roll
California roll
Vegas roll

Wow the my favorite was the Vegas roll the combo with the crispy outer layer and the fresh fish on top with avocado with sauce oof it was delicious a must order option!
Everything was delicious and what made the difference was freshness.

I would definitely come here again or order out, but it seems a lot of people order out. Dining in was a great experience and more need to come and experience everything as well at least when they can.

Parking was a bit difficult, one level and easy wheelchair access.

You can get vegetarian options here or ask what they have :)

Overall my experience was pretty great and those who love sushi definitely need to try this place out.“

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

“Great food I would recommend“

“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.“

“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.“

“Worth the wait“

“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 .“

“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!!!“

“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.“

“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“

“Thank you again Sanyo staff for being AMAZING to my special needs daughter!! Thank you for being great to us!!!! And thank you for giving us a safe place for our baby after another place threw us out because she was having a hard moment. You guys accommodating us made my heart happy even though i cried outside!! All i have is thank you for making a family with a special needs child feel welcomed. Your staff is the MVP thank you!!“

“AB Shabu Shabu is one of my favourite shabu places in this area. I've been coming since childhood, for longer than I remember (maybe 15 years?), and it's remained such a lovely restaurant that my family and I keep coming back time after time.

The meat is always so tender and delicious. I usually get either the angus beef short rib or the beef ribeye, and both options are always so fresh and flavourful. The medium size is my preferred portion size -- filling but without feeling too stuffed.

The meat goes so well with the rich and savoury beef bone broth, which is my go-to. I also really like the sukiyaki broth, which is a perfect balance of sweet and salty and goes so well with the beef.

The veggie plate that comes with the hot pot is a lovely finishing touch -- all the vegetables are so fresh and yummy when cooked in the delicious broth. The portions are very generous and complement the meat very nicely for a very well-rounded meal overall.

The price point is also very reasonable, especially in the past few years as dining out has gone out so much :') Portion size is very fair and very filling. The owner is also such a nice guy -- it's been the same person running the show as far as I can remember, and he's always so eager and kind to everyone.

Cannot wait to come back again soon!“

“Marugame Udon in Chino Hills is such a comforting spot; especially on a cold, rainy day. Their udon soups are absolutely delicious, warm, and full of flavor. You can really taste the freshness in every bowl.

As a first-time visitor though, I will say the ordering process was a little confusing. A clearer sign or simple explanation for newcomers would go a long way. The layout of the tables also feels a bit uninviting and could definitely be improved to make the dining experience more comfortable.

With that said, the staff truly made up for it. Everyone was warm, kind, and welcoming, which I genuinely appreciated. Overall, great food and great people; just a little room for improvement in the flow and layout. I’ll still be back for that amazing udon! 🍜“
