Great tasting food, fresh sushi! It was pretty crowded for a Monday night!! From Bay Area so had high expectations and they delivered. She could've given us more water but server was only one working as we came at 8:30 pm. read more

Mixed feelings about Hikira Sushi. I feel it's just a nothing special restaurant. Formerly Mary's Japanese restaurant long ago, this places opened in January 2026. Had good reviews so we decided to try it out. It serves sushi and Japanese food. I typically rate a Japanese restaurant on 2 basic entrees, miso soup and tempura. If they get these basic Japanese dishes right, typically everything else is pretty good. The pros: Clean with big tables that give a family of 4 enough elbow room. Tempura and chicken katsu were fried just right. They got the tempura right. The chicken katsu my wife had was juicy and not dried out. The cons: Miso soup was decent. Like a 7 out of 10. It lack flavor like not enough miso. It wasn't salty which is good, but I also did not taste the dashi (bonito flake) base that provides depth to the soup base. Needed more tofu as well. The sushi was nothing special. The size of the raw fish was nothing special. It wasn't anything that stood out. The California Roll was also basic. Nothing special, not even sesame seeds. The rice seemed skimpy as well. Price wise, to me it seemed over price for the sushi for what you received. Nothing worth mentioning or exciting about this place. I also tried the Matcha Beer. If you like hoppy beers and IPAs, you might like it. I on the other hand prefer Sapporo or Asahi. Conclusion: Unfortunately, I had high hopes for this place and it just didn't deliver in my opinion. read more

This is my favorite sushi place in the whole area. Hard to beat the freshness, flavor combinations, and friendly staff. I love coming here for their lunch specials, which always have a great value, or for any of their rolls. It's always a good balance of flavors, spices, great fish, and perfectly seasoned rice. Whenever I crave sushi, this is my go-to place. read more

03/10 stopped in for lunch special serving until 2 Warmly welcomed in by Cailin! We were immediately seated! Cailin was super attentive and very polite! My husband loves the yellowtail nigiri it's fresh and delicious very good cut and he loves side ponzu sauce! My hubby ordered the spicy chicken, rice and yellowtail roll and sashimi which was extra to add but worth it! Spicy chicken was packed with flavor and the chicken wasn't dry! Highly recommend! I love their veggie and shrimp tempura! Nice light and not too greasy lol! My daughter ordered the sashimi lunch special and the rainbow roll which came with the salad and she killed her plate! read more

Ordered a PREMIUM chirashi for take out, so can't say much about the service. Ambiance is standard for Japanese restaurant - nothing extraordinary. Chirashi bowl itself was solid. They gave a nice mix of fish, the uni was actually of decent quality. Toro etc - definitely what you'd expect from a premium chirashi bowl. My only problem (and the biggest problem) is that they gave a horse radish pack? Like why? New establishment - had every potential to be great but decide to cheap out on wasabi? I can understand if its for those California/Philadelphia roll orders but on a premium chirashi? How unfortunate. read more

Every week for lunch, a coworker or I roll a dice to pick what is gonna be the restaurant we go to, and a few weeks ago, Hikari Sushi was what the dice decided on. We came here on a Thursday for lunch. This place took over the spot that Kamis Sushi used to be at in the plaza with Sprouts, Ace Hardware, Coffee Bean & Tea Leaf and Chipotle. The layout of the restaurant was familiar from the previous restaurant but the decor was definitely cleaned up and brightened from the previous place. Service was quick and attentive. We both ordered lunch specials, his was a katsu bento w/ sashimi and mine was 9-piece nigiri with a roll. Fish tasted fresh and were solid, thick cuts of a large variety, overall, I thought it was a good price for a lunch special. I'd definitely return here to give a try of more of their menu for dinner. read more

Hikari Sushi - Lunch Special Combos - Japanese Near Me - Diamond Bar, California

I was looking for sushi around Diamond Bar and saw this new sushi restaurant nearby! I ordered the Garlic Chip Tuna Roll, Seared Cajun Salmon Roll & 20pc Sashimi for two people - had SOO much leftovers. The rolls are HUGE and taste wonderful. I love the flavor of the Cajun and how fresh the Tuna roll was. The Garlic Chip piece was the perfect crunch to the roll. Between the two of us, we couldn't even finish a roll, so we had plenty of leftovers. I highly recommend getting the Sashimi 20pc if you love sashimi- it's so worth it. The cuts are HUGE and there was 8 different types (if you include the krab salad). Our server was so sweet and accommodating. The ambiance was very chill and warm. They also have a lunch special bento box that I'll try next time. I highly recommend on stopping by if you're in Diamond Bar! read more

Seriously can't believe I ate sushi two days in a row! What has come over me?! Haha their tuna was amazing and fresh and I avoid tuna since it always disappoints. Hope they continue to keep up the quality of fish as the months go on. My Alaska roll was buttery + savory and I enjoyed every bite. Their lunch specials are noteworthy and I got their combo b with choice of specialty roll. I also commend the aesthetic of the plating, menu descriptions, and cleanliness of the inside! read more

This place is really good. I will definitely go back to try other items. It used to be another sushi spot before and I'm glad they decided to open another. It did feel a little chaos when they were trying to seat everyone on busy night but figured it out after waiting 30 mins with no reservation. We ordered and got our order pretty quickly with good timing in between each entree. We ordered the 12 piece omakase, shrimp and veggie tempura, and Baja roll. Everything was amazing. Fresh and delicious! read more

The food was fresh and very tasty. The portions were generous. Don't hesitate to try it. read more

Overall pleasant experience at Hikari Sushi. It took us around 5 minutes to be seated, even though there were open tables. This was because the restaurant was very busy with only one server, so I dont hold it against them. The food was amazing! Everything we had was great. My party thought the music was a bit loud, although I thought it was fine. Overall, an amazing new restaurant that has an extremely cozy and interesting interior serving up banger food that at the moment seems a tad understaffed. Once those issues get fixed, easy 5 stars! read more

We love sushi and okay to spend the money if the food is good, and this food was good. Spicy Garlic Edamame is probably the best weve had from any place. This was actually Spicy, garlic, and not sweet. The Edamame was made well. I had to stop myself from eating to save for the rolls. We usually get Sashimi or Nigeri but this place was very pricy for those (2 pieces for $18-$25) so we stuck with rolls. Cajun Salmon and Cajun Tuna were smokey seared fish, not really Spicy. Lemon Yellowtail was refreshing and tart. I limit my rice intake so I ordered the Energy roll and this was very good. The sauce added a little sweetness to the rolls. Fish were fresh. The rolls fell apart but each piece was very good. Service was great! All workers were very friendly. read more

Incredibly fresh and skillfully cut sushi! I was very happy with the quality and fish-to-rice ratio. It's important to me each bite holds together and I think they really know what they're doing. They have the easiest menu to navigate in Diamond Bar, so I had a nice takeout experience. The location is cute, and everyone inside is super friendly. Service was helpful and I recommend this place to anyone in Diamond Bar that needs a sushi fix. read more

My husband and I tried this place during the lunch special bento box. We were very satisfied with our order. The combinations were great and we got so full for literally the rest of the day! The sushi was exquisite with great cuts. I also ordered a green tea which came with a cute tea pot to refill my own cup throughout the meal. The decor was nice with Japanese art and some anime decor. The service was very attentive and kind. We definitely will come back and wish them well! read more

We were staying in Diamond Bar while visiting some family and stumbled on to this place. Very impressed. Service was excellent, fish was very fresh the restaurant was very clean.

We had the Karage chicken, cucumber & Crab Sunomono, Red Roll (no rice & very good), medium fatty tuna sushi - so good, freshwater eel - amazing bbq/wood flavor), mackerel, & Halibut.

Cajun salmon roll and tuna crispy rice were bomb! Service and music were good. Will come back again. :-)

New spot opened last week, took over former Kami sushi location. Renovated the space - open airy vibes, got rid of the tvs and dark decor, definite upgrade. Menu covers everything from sashimi to cooked food so something for everyone. Ordered the chirashi... got a better-than-average cut of tuna, a piece of salmon belly which is a pleasant surprise, overall everything was fresh... but weirdly also got a stick of imitation crab? Like.. strange thing to get in a chirashi bowl and I felt like that cheapened the whole bowl but it's fine maybe some people are into it? lol. Oo almost forgot I also got a shrimp nigiri. Shrimp was normal but the fact that it came in nigiri form inside my chirashi was a little weird but maybe an aesthetic choice bc it looked cute for the photo? lol. But that was overshadowed by the discovery of the crab stick. lol overall though will come back and try more of the menu. Food and service both seem pretty solid and the ambiance is good. Welcome to the neighborhood Hikari! Glad to have you here. Good luck! read more

Back again to try different dish for dinner. Have been very pleased with previous meals. Today I had the seafood yakisoba-- so delicious! We shared dishes, and were able to taste the salmon, tempura and sushi. All very delicious! It was my husband's first time here & he loved it. The matcha IPA beer was a fun treat. The staff is super nice. The place is very clean and elegant appearing with a serene Japanese decor. Love coming here. Never have to wait and the service is perfect. read more

So good. Everything tasted really fresh and clean. The sashimi bowl was my favorite -- thick cuts of fish, super buttery, and the uni and salmon roe were perfect. You can tell the quality is there. We also got a specialty roll that was packed with flavor but didn't feel heavy, and the yakisoba was simple and really satisfying. Even the shishito peppers were great. Really solid spot if you're craving fresh sushi. I'd definitely come back. read more

Came here for lunch on a Sunday and got the lunch combo B, the black snapper nigiri, and the yellowtail belly nigiri. There weren't many people during this time so they weren't very busy and it was pretty quiet in there. The food took longer than expected to come out. Not sure why because there were 2 sushi chefs. However, the waitress was very attentive. The lunch combo was delicious and I appreciated that they put the salad dressing on the side. Initially I wanted to get the red snapper nigiri, but was told they were out of the red snapper. So I ended up getting the black snapper to try and it wasn't my favorite because it had a weird texture to it when I would chew on it. read more

The food is amazing, the sushi is extremely fresh, the hospitality is amazing. The owners are very nice and friendly. Very happy to support them. The problem is we live too close to them and their food is addicting! We have had the Oysters half shell, my favorite is Toro, the Salmon belly, Uni, fresh shrimp. I am not a roll fan but my kids are addicted to their rolls. Especially the Energy roll. Trust me. I am picky about my sushi and this place is my new favorite. They are getting busy and full so I suggest calling for reservations. The place is very cozy. I must also mention that the Ramen is very authentic. read more
