Sushi Masa by Ki-setsu kept appearing everywhere.
Food blogs. Review sites. Social media. Recommendation threads. Google reviews. Those “best omakase in Singapore” lists that somehow always make you feel poor and hungry at the same time.
At some point, we lost count.
Which was strange because nothing about this restaurant makes business sense.
It is not in a luxury hotel. It is not in a premium shopping mall. It is not Michelin-starred. It is not even somewhere you would casually walk past after buying skincare or losing money at Don Don Donki.
An Omakase Experience on Level 6 of Cuppage Plaza Singapore
Sushi Masa by Ki-setsu is hidden on Level 6 of Cuppage Plaza.
It is old, slightly confusing, and has the energy of a building that has seen many things and will not be discussing them publicly.
So why this place?
How did an almost invisible 8-seat omakase hidden on Level 6 of Cuppage Plaza become one of Singapore’s most talked-about omakase restaurants?
We went to find out.
The food that made us shut up for a while
The tuna series that changed the mood
Let’s start with the food, because the food defines everything.
Not the location. Not the branding. Not some dramatic chef backstory polished until it shines like hotel marble.
The food.
The tuna series came first: akami, chutoro, otoro. The holy trinity of omakase tuna, and also the easiest way to expose whether a sushi counter is serious or just expensive.
The akami nigiri was clean, fresh and deep, with that quiet umami that lingers without shouting. The chutoro was softer, richer, more persuasive. The otoro was, of course, the show-off.
But what surprised me most was how clean everything tasted. Almost no metallic taste. Almost no iron notes. No fishy funk trying to pass itself off as “character.” Just texture, temperature, fat, rice, and restraint.
This is harder than it sounds.
Bad tuna announces itself like a loud uncle at Chinese New Year. Good tuna does not need to explain anything.
Then came the otoro finished over an actual open flame and served with leek.
Not standard aburi. Not the usual quick torching that makes every piece of fish taste vaguely like a burnt office pantry. An actual open flame.
Who even does that?
The result was different. The fatty tuna’s fat softened without turning greasy, the leek added sweetness and smoke, and the whole thing felt less like a trick and more like a decision.
The small details that gave the game away
Then the amaebi nigiri arrived.
One of the largest sweet shrimp I have seen at an omakase counter, served cold on warm rice. The contrast was lovely: cool, creamy shrimp against lightly warm, seasoned rice. Instead of leaning lazily on soy sauce, it was finished with salt flakes and yuzu zest.
A small thing. But small things are where omakase lives or dies.
The shrimp had that creamy sweetness you want, without the fishiness that sometimes sneaks in and ruins the mood like an unsolicited insurance pitch.
The anago was another moment.
Plump. Fatty. Slightly juicy. Almost luxurious in texture, but not in the flashy “look at me, I cost money” way. Chef Masa explained that it comes from one of Toyosu Market’s top suppliers, and that this supplier is not easy to buy from.
Normally, when chefs say things like this, I prepare my inner auntie to be skeptical. Everyone has a “special supplier” these days. Even my cai png stall probably has a “curated cabbage partner.”
But here, the eating matched the talking.
The monaka sealed it.
A crisp shell filled with chopped chutoro, otoro, and house-made sauces. Rich, crunchy, fatty, savory, messy in the best way. Chef Masa mentioned that some of the sauces take four to six months to mature.
Four to six months. What precision. What Tradition. And look at how it was presented.
For something many diners would eat in four to six seconds.
In fact, every dish, from seasonal appetisers to sashimi and sea urchin (uni) were crafted with unwavering focus and a deep philosophy rooted in Japanese cuisine. The art of balancing flavors shines through each course, culminating in a dessert that perfectly closes the experience. While these may seem like familiar dishes, Chef Masa elevates every single one to an extraordinary level.
That was when the restaurant started to reveal itself. Behind the calm counter, behind the quiet service, there was a lot of invisible labor. Not Instagram labor. Real labor. The Team nobody claps for because nobody sees it.
Located at Level 6 Cuppage Plaza, where restaurants go to disappear
The strangest part of the night was getting there
Arriving at Sushi Masa by Ki-setsu is almost surreal.
You take the lift up to Level 6 of Cuppage Plaza, and suddenly the building gets very quiet. Not peaceful. Quiet. There is a difference.
There are no surrounding shops trying to sell you bubble tea, eyebrow embroidery, or suspiciously discounted massage packages. There is no restaurant cluster. No buzz. No helpful smell of grilled meat guiding your hungry body forward.
Just stillness.
Sushi Masa by Ki-setsu is the only restaurant on the level. This intimate dining experience actual feels more like a private booking.
This is the part that truly makes no sense. In Singapore, we are trained to trust crowds. Queue means good. Empty means danger. If a place has no foot traffic, we assume something has gone wrong.
But nobody accidentally discovers Sushi Masa.
You do not wander in because you were nearby. You do not “just happen” to find it after shopping. You have to know. You have to make a reservation. You have to intentionally search for it.
Why it felt oddly more Japanese
And oddly, that made it feel more Japanese.
Not tourist Japan. Not the Japan of neon signs, giant crabs, and TikTok itineraries. I mean real Japan, where some of the best restaurants are hidden inside old buildings, aging shopping centres, and anonymous upper floors because the food does all the marketing.
This honestly felt more Japanese than many Japanese restaurants in Singapore.
No grand entrance. No expensive lighting trying to seduce you. No dramatic “concept.”
Just a counter, eight seats, and a chef who seems more interested in fish than theatre.
The business model that made us question capitalism briefly
One seating, eight counter guests, and somehow a full restaurant weekly
Then we found out how Sushi Masa by Ki-setsu operates.
One seating per night. Eight guests. Five operating days per week. No lunch service.
Excuse me?
How is this even a viable business?
Singapore restaurants usually survive by turning tables, optimizing manpower, doing lunch sets, pushing drinks, hosting corporate dinners, and praying rental does not behave like a loan shark.
Sushi Masa seems to have looked at all that and said, no thanks.
Not financially sensible, but operationally clear
Ingredients arrive from Japan in the late morning. Afternoons are spent preparing. Chef Masa does not finalize the menu until he sees what comes in. He evaluates quality, seasonality, and availability before deciding what diners will eat that night.
There is also a personal buyer in Japan helping to source seafood before shipment.
So the restaurant is not built around operational efficiency. It is built around ingredient quality.
At this point, the restaurant started making a little more sense. Not financially. Operationally.
The model is irrational if you think like a spreadsheet. But it makes sense if the entire point is control: control over ingredients, timing, preparation, and the number of people being served.
Eight guests means no hiding. No shortcuts. No “kitchen is busy tonight” excuse.
Every piece has nowhere to run.
So why is Sushi Masa so popular?
The part that still doesn’t fully add up
We left Sushi Masa by Ki-setsu still slightly confused.
Not because the food was disappointing. The food was exceptional. The value also felt unusually strong. At $230 and $320, the omakase menus prices are not cheap, obviously. This is still omakase, not economy rice with fish upgrade.
But compared with many omakase meals in Singapore that cost significantly more and somehow leave you emotionally unmoved, Sushi Masa feels competitive. Maybe even dangerous to the market, if enough people find out.
Which they already have.
So why is Sushi Masa by Ki-setsu so popular?
Maybe because the food speaks louder than the location. Maybe because diners can sense when effort is real. Maybe because in a city full of polished concepts and expensive interiors, there is still something thrilling about finding a restaurant that should not work, but does.
Nothing about this restaurant makes business sense.
One seating. Eight guests. No lunch. No foot traffic. Hidden on Cuppage Plaza Level 6.
We still do not know if this model is sustainable in the long run or will it break. But after spending an evening here, we finally understood why people keep talking about Sushi Masa by Ki-setsu.
