Since we moved from Town to Kapolei, wife and I have been wanting an authentic sushi type place and we stumbled upon Yoichi owner of Sushi Koh. Parking is small but plenty other spots you can park by and walk over and place fits a total of about 8-10 people. We didn't make reservations and was able to get a seat for two. Menu had a lot of choices from Specials, Ngiris, Handrolls, Donburi's, and Dessert. Service is a little slow as he is the only person running the show giving you that personal connection with him that the wife and I didn't mind waiting. He was making everything to order and I eat a lot so I was making him work that the day we went in. Food was great! Fish was fresh, and the size portion for the prices was shockingly reasonable especially when you get his donburi. Ambiance was great, the place is very small that conversations flow through each guest and food is so good that everyone will be talking to each other asking what they ordered and that the order looks tasty. Overall experience with Yoichi at Sushi Koh was great that the wife and I will be stopping in more and not having to drive to town for some authentic sushi. read more

A true hidden gem in Waipahu! Sushi Koh is an authentic Japanese restaurant tucked between K's Bento and Heart to Table, with fewer than 10 seats--so it feels incredibly intimate. The fish was high quality, but what really made the experience special was Chef Ito. He's incredibly talented, warm, and friendly. Sitting at the counter felt like we were right in his kitchen with our own personal chef. Chef Ito also makes his own desserts, and they rotate depending on what's available. The hoji-cha cheesecake was AMAZING! I can't wait to go back and see what dessert he has next. Definitely looking forward to another visit! read more

Went on August 31, have some patience as it is a one man show doing everything. Had Negitoro and Salmon bowls that was amazing. Chutoro sashimi was to die for. We also had two Chutoro nigiri, but better value getting the sashimi. Chef Ito is very friendly and easy to talk to making the experience enjoyable. Hidden gem in Waipahu that should not be hidden! read more

Hidden little gem in Waipahu. Unassuming looking Sushi bar on the outside nested between K's Bento and Heart to Table. Owner Yoichi is the sushi maker and runs everything by himself in the clean and cozy sushi bar. I stumbled on this place looking for lunch and found out they do takeout. I ordered a couple of poke bowls to go. Poke made with sashimi quality ahi. Yoichi was friendly, informative and accommodating. He allowed me to make a fish substitution in my poke bowl. Poke bowls tasted fresh and flavorful. Will definitely be back. read more

Sushi Koh is the best omakase Ive had in Central Oahu. The sushi chef is very friendly and knowledgeable. The omakase is 130 per person for sashimi, (12) piece nigiri, uni and ikura chawanmushi, salmon skin salad, and dessert. All of the fish is fresh, and the chef creates a unique experience or flavor for each piece or dish. I am definitely returning here, and trying some of the bowls. read more

So excited for a new sushi spot! ...and in Waipahu at that! Sushi Koh is located right next to K's Bento (another Waipahu treasure!). If you're not familiar with Waipahu, this spot is going to be very hole-in-the wall type for you . It's small- we're talking 6-seater small, and a one man show, but I loved the intimate setting. The restaurant was clean, and the fish was delicious. My first visit was during his lunch hours (1130-2). Got there right at 1130 and there was only one other party there. I had a negitoro & ahi don and uni nigiri! So good. It also came with miso soup and fresh wasabi . The owner was friendly and down to Earth. Enjoyed talking story with him! I also appreciated that he didn't force himself upon us with small talk. He let us eat our lunch in peace first lol. Also, we were a little surprised to hear him speak in Japanese with his other customers, so there's also that if you need it . Parking can be tight- there's about 3 stalls right up front? Otherwise you can park right across the street Can't wait to go back for dinner! read more

Thank you to Chef Yoichi! Lots of fresh, unique fish including local bluefin, fatty sardine, and orange sea bream! Thoughtful preparation and delicious nigiri. Dessert special hojicha cheesecake with mandarin orange was creative, surprising, and well balanced. We can't wait to come back! read more

Waipahu' New Hidden Gem Sushi Koh just opened in September 2025, and it's already easily one of Waipahu's best-kept secrets. Tucked right next to K's Bento and Heart to Table, this tiny sushi bar seats only eight people total, giving it an intimate, personal feel you don't find often anymore. We went as a family of seven, and even though the place is small, the seating felt cozy rather than cramped. They take reservations, and we were able to call just a few hours ahead to book a 7pm spot--which was super convenient. Another bonus: it's BYOB, which made the night even better. The prices were shockingly reasonable for the quality. My other half ordered an omakase bowl for just $12, and it was fresh, beautifully prepared, and honestly a steal compared to most sushi bar spots in town. If you love trying new local spots before they get popular, Sushi Koh is absolutely worth checking out. Amazing value, fresh ingredients, and such a welcoming vibe. Can't wait to go back! read more

I seriously never write reviews on Yelp, but this place is AMAZING. It was the most authentic Japanese sushi i've ever had. We were the only ones in there, and the owner is the one who runs the sushi bar & makes the sushi. He was so cool and made the experience even better. He had us try seasonal special dishes and you could tell was EXTREMELY talented, passionate about what he does, & knowledgeable. This one of the best places i've ever been to in my life. The quality is incredible and it straight melts in your mouth. The sauces were incredible. Everything was truly amazing. It was one of the coolest places i've ever tried or been to- please go here. Also because I work in senior care- anyone who has older Japanese parents too or want something super authentic this would be perfect. The abalone was still alive right before he prepared it. He let me keep the shell. Go here and ask him about the dishes- definitely 100000/10 and a hole in the wall. read more

Just found out about this place from a fellow Yelper. Decided to go around lunch time after doing errands. It's located next to Heart 2 Table restaurant and K's Bento-ya. Walked in and it was a small restaurant, seats about 8 customers! Kinda reminded me of the Golden Gai bars in Japan, which I enjoyed because you get the attention of the sushi chef! And lucky me I was the only customer! I ordered the omakase because I couldn't make up my mind on what to eat! Yoichi, the sushi chef prepared what he had that day and I gotta tell you....it was the best sushi on the leeward side I ever had! I happily told Yoichi that I don't have to drive all the way to town for ono sushi! Everything I had was so delicious! See pics of what I had. I had more but I was so hungry I forgot to take pics. I enjoyed my meal and talking story with Yoichi and learning about the restaurant. Kinda reminds me of Sushi Masa days...sit and eat and talk story with the chef. I highly recommend this place! If you have a big party reservations are recommended! I'll be back again! read more

I recently tried Sushi Koh and it is such a chilled, laid back sushi spot. It is the kind of place you go when you want really high quality fish without the high end price tag or stiff atmosphere. The uncle chef runs the whole place by himself, which honestly makes the experience even better. He is super funny, loves to talk story, and makes you feel like you are just hanging out at his kitchen counter. The sushi was premium and surprisingly reasonable for the quality. They also have donburi sushi bowls available for take out, which is perfect if you want something quick but still fresh and elevated. They carry some unique seafood options that I had never tried before, which made it feel a little adventurous in the best way. Next time I am definitely coming back to try their omakase. read more

Discovered Sushi Koh early on. I didn't write a review earlier tho I agree with others that it is very enjoyable. The dialog, quality, and ambience makes for a great experience. Have returned a few times and also love that it is BYOB. The addition of dessert dishes are a plus! He is always entertaining and attentive which only adds to the enjoyment of the food! read more

Its a hidden in the wall kinda place. I love it, the vibe, the friendliness of the chef. Felt very personal one on one. Seating is limited due to it being small.

Had a late dinner after reading all the positive reviews. We were not disappointed. First of all, the owner runs a one man show. Super friendly- personable guy.

We just tried this small locally run sushi place in Waipahu and were very pleasantly surprised at how fresh the fish and other sushi items were. We had their ten piece $12.00 nigiri lunch special and all the items were delicious. It came with miso soup and was well worth the price. We will be going back to try their regular menu sushi items soon. read more

Great new sushi place in Waipahu! Food was so good that I forgot to take photos of it, but this is the only photo I got and my son ate all of his nigiri set. The owner was so friendly and nice. We really wanted to try the omakase but we didn't know that needed to put an order a day in advance, which was fine because whatever we ordered was still yummy! We also tried the bara chirashi, uni, toro, and salmon skin temaki. Alcohol is BYOB. Will be returning to try the omakase! read more
