I had lunch here and I loved it! The sushi and fish was incredible and I enjoyed watching Chef Masashi-san and his other chefs/staff cut the fish, grate the wasabi, and making the sushi.
Each sushi and dish was remarkable and the attention to detail was immaculate. The place was quiet and serene and Chef Masashi-san didn't speak that much at my lunch but I noticed he had this quiet cool confident demeanor and he was friendly to all the guests. Either he or the other chef/staff would explain the dish to us and the staff were attentive and friendly too.
It is close to the metro station and it could be hard to find. I accidentally went to the wrong building at first as I was met with a dental office and remember it's on the 7th floor. Once you reach the restaurant you'll know right away you're at the right place with it's beautiful decor and attentive staff.
Overall this might be the best sushi I've had and definitely would love come back another time!
An exceptional omakase experience from start to finish. Every piece of sushi was beautifully crafted, showcasing outstanding quality, precision, and balance. Chef Masashi’s creativity shines through while staying true to traditional Edomae techniques. The service was warm and attentive, and the intimate atmosphere made the meal even more memorable. Easily one of the best dining experiences I’ve had. Highly recommended.
Sushi Masashi is a masterclass in modern Edomae sushi. Located in a sleek, intimate space in Kita-Aoyama, Chef Masashi Yamaguchi delivers a Michelin-starred experience that feels personal and unpretentious. While the nigiri is technically flawless—featuring perfectly seasoned, high-acidity shari—the creative appetizers like the signature Tuna Sukiyaki truly set this omakase apart.
At approximately ¥40,000, it is a significant investment, but the quality of the fish and the chef’s engaging hospitality justify the price. The atmosphere is warm and welcoming to international diners, making it one of the most accessible high-end seats in Tokyo. Secure your reservation weeks in advance via OMAKASE; it is a mandatory stop for anyone seeking elite sushi outside the stiff formality of Ginza.
One of the best omakase experiences I’ve ever had—if not the best. Absolutely everything about this place exceeded my expectations. From the food to the service and attention to detail, every aspect was exceptional. I only hope I’ll have the chance to come back someday!
I went to this place with very high expectations.
The restaurant was almost impossible to find from street level – I would strongly recommend looking at the Google listing for exactly where you go – you get into an unmarked elevator and go to the top floor. It was hot inside – I wore a sweater and was uncomfortably hot the whole time. Totally my fault.
The experience of dining here completely blew my very high expectations out of the water. The staff were extremely friendly and respectful and communicative – the presentation of the food, and the quality of the food is impossible to describe without experiencing it.
We were served a first course of puffer fish – this was given to us nonchalantly, although it is a world famous item that can kill you if not prepared correctly – I had no concerns eating it.
I could spew about this place for days – overall I will go back to Tokyo just down here again. It was that good.
The chef even asked if we were still hungry towards the end of the meal Dash unfortunately I was full, but he made everybody that was still hungry. I hand roll with any remaining fish.
Seriously, just out of control, quality and presentation.
