A micro kitchen is a small food station placed on each office floor. There is no cooking kitchen behind it: it holds drinks and snacks, and employees help themselves. It has become standard in the Tokyo offices of global companies, yet almost nothing has been written for the people who actually have to install and run one. This article covers how a micro kitchen differs from a cafeteria or an office cafe, why permit requirements are not one-size-fits-all, and how to design the utilities and the daily operation behind it.
A micro kitchen is a compact food station in a corner of a working floor. It typically combines a coffee machine, a hot water dispenser, a refrigerator, a microwave and a sink with snacks, drinks and fruit. Despite the name, no cooking happens there. It is a place where restocked food and drink are picked up by employees themselves.
The format spread from US technology companies. Putting one on every floor means people do not have to travel to a single canteen to take a break. The point is less about saving walking time and more about creating a place on the floor where unplanned conversations happen.
These three get confused constantly, but they differ in equipment, in staffing, and in how permits have to be approached.
The difference is not which one is better. It is where you place the people. A micro kitchen has no one out front, which means it needs people behind it. Invisible operations are not the same as no operations.
This is the question we are asked most, and there is no universal answer to it.
Whether a food business permit is required depends on what actually happens at the station. Setting out pre-packaged food and drink for people to take is treated differently from portioning or plating on the spot. Whether the space serves employees only, or visitors as well, also changes how it is viewed.
What makes this harder in practice is that the same setup can be judged differently by different public health offices. Requirements around sinks and hand-washing are not always applied at the same level from one district or officer to the next. Applying generic guidance written for opening a restaurant will often conflict with what you are actually told.
So we strongly recommend this order. First, settle what you will offer and how it will be handed over. Second, take that specific plan to the public health office that will actually issue the permit, and consult them in advance. Third, finalise the equipment specification on the basis of their answer. If you order equipment first and consult afterwards, the rework reaches into construction.
What stalls a micro kitchen is rarely the equipment. It is the building.
Water comes first. Where the supply and drainage come from, whether an existing pantry can be reused, whether new lines are needed. Depending on the floor structure, you may not be able to get drainage fall to the spot you wanted.
Power is next. Coffee machines and refrigerators draw more than people expect. Assuming an existing outlet will do, then discovering a dedicated circuit is required, is a common piece of rework.
Then ceiling height and delivery access. When reusing an existing area, dropped ceilings and beams frequently mean the equipment you specified will not fit. Measuring on site beats reading drawings.
Because nobody is stationed there, the operating design is the quality.
Decide the restocking frequency and time of day, who holds the stock, the scope and owner of cleaning, and the escalation path when something runs out. Running out is the single most visible signal to employees that the operation is not working.
Decide early whether restocking sits with your own facilities team or with an operating partner. Starting in-house and then finding that the daily workload is larger than expected is a common path. Estimating the workload from floor count and headcount up front prevents that mistake.
On hygiene, decide how far you will go on expiry management, refrigeration temperature logs and cleaning records. Separately from whether a permit is required, records are worth designing as something that protects you when something goes wrong.
Once one floor works, the conversation turns to rolling it out. What matters at that point is whether you decided up front how much would be standard.
What is stocked, how often it is restocked, the cleaning standard, how ordering works. If those are improvised floor by floor, the moment you add sites you lose control. Build one standard and hold only the per-site differences as data, and the operating load stops scaling with the number of sites.
When we take on corporate food operations, we spend the most time on the design of the very first floor, because that is what becomes the standard.
It depends on what you offer and how it is handed over, and there is no universal answer. Setting out pre-packaged items is treated differently from portioning on the spot. The same setup can also be judged differently by different public health offices, so settle the plan first and consult the office that will issue the permit before ordering any equipment.
A cafeteria cooks and serves meals and needs kitchen infrastructure and staff. A micro kitchen offers drinks and snacks with nobody stationed there. If you want to serve proper lunches, you need a cafeteria. If you want more places to take a break and talk, or you cannot build a kitchen in the space, a micro kitchen is the realistic option. Many companies run both.
Not stationed on site. But someone still has to restock, clean and manage inventory, and you have to decide whether that sits in-house or with an operating partner. No visible staff is not the same as no operation.
Yes. It is a floor-level installation by design, so there is no meaningful minimum size. The real constraints are water and power, and whether an existing pantry can be reused largely decides feasibility.
Decide what you will offer and how it will be handed over, and physically check the water, power and ceiling height of the space. With those two in hand, both the health office consultation and the equipment quotes become concrete. We are happy to talk before requirements are fixed.
