“Just heating” is all you need.
Modern multi-function microwave ovens that sit in today’s kitchens are truly versatile cooking appliances, with features like oven functions for baking bread, grill functions for cooking fish, and even capabilities for steaming and oil-free cooking. However, are you really making the most of all these functions? Many people might feel, “I only ever use the ‘reheat’ button” or “The operation is so complex that I need to read the manual to use most features.” If your daily routine mainly consists of defrosting frozen rice, reheating lunch boxes, or warming up a cup of drink, those complex functions might not only be wasted but also taking up unnecessary space and cost.
This article is the ultimate guide to finding the best “single-function microwave” recommendations, especially for those who relate to the above sentiments. Single-function microwaves, with their admirable simplicity, are once again fitting into many people’s lifestyles and being re-evaluated. From their appeal to the golden rules for choosing without regrets, and even the characteristics of popular manufacturers, we’ve condensed all the knowledge you need to find the perfect companion that will make you think, “This is the microwave for me.”
Why choose “single-function” now? The rational and smart reasons
In a modern world overflowing with complex and high-function products, choosing a “single-function” product is not a step backwards, but rather an extremely rational and smart choice that deeply understands one’s own lifestyle. There are clear reasons why single-function microwaves are supported by diverse generations.
- Overwhelming cost-performance:
The biggest attraction is the price. Without complex heating mechanisms like ovens and grills, the structure is simple and requires fewer parts. This allows for models with sufficient performance to be available for around 10,000 yen or less, compared to multi-function microwave ovens that cost tens of thousands to over a hundred thousand yen. For students starting a new life or new working adults, there’s no stronger ally. - Intuitive operation anyone can use:
Because the function is specialized in “heating,” the operation panel is very simple. Many models have dial-type controls where you only need to set the power (wattage) and heating time, allowing even elderly people who are not good with machines to use them intuitively without reading a manual. You’re completely freed from the stress of “What if I press the wrong button?” - Compact and easy to place:
With no extra functions, many models are compact in size, making them easy to install in kitchens with limited space in single-person apartments or office pantries. It’s also possible to use them as a second microwave in living rooms or studies. - Easy maintenance:
Using oven or grill functions can make the interior very dirty with oil splatters or burnt-on food, making cleaning very difficult. Single-function microwaves are basically for heating only, so the interior doesn’t get very dirty. Even if it does, you can easily maintain cleanliness by simply wiping with a cloth.
These benefits can greatly change the daily lives of all those who think “heating” function is enough, making them more comfortable and simpler.
[Most Important Selection Point 1] Turntable or Flat? Which is right for you?
The first and most important decision point in choosing a single-function microwave is selecting the “table type” of the interior. This greatly affects usability and ease of cleaning, so understand the merits and demerits of each correctly and choose the one that suits your usage.
Turntable Type: Traditional and less uneven heating
This type has a round glass plate installed in the interior that rotates during heating to evenly distribute microwaves to the food.
Merits: It’s the most classic and perfected method for microwaves, and the biggest advantage is that rotating the food reduces uneven heating. The simple structure tends to make the unit price relatively inexpensive.
Demerits: The plate takes up space in the interior. Especially when trying to heat large, long lunch boxes, they may get caught on the interior walls when rotating, preventing proper heating. Also, when cleaning, you need to remove and wash the glass plate and the rotation roller underneath, which might feel a bit troublesome.
Recommended for: Those who mainly heat drinks, rice on round plates, or small convenience store lunch boxes. Those who want to keep the price as low as possible.
Flat Table Type: Spacious and easy to clean
As the name suggests, the bottom of the interior is completely flat with no turntable. It heats food by diffusing and agitating microwaves in the interior.
Merits: With no protrusions in the interior, space can be maximized, allowing large lunch boxes and square plates to be smoothly inserted. The flat bottom makes cleaning very easy, requiring just a quick wipe with a cloth.
Demerits: Depending on the position of the food being heated, some models may have uneven microwave distribution, resulting in partially cold food. Also, the structure is slightly more complex, tending to make prices slightly higher than turntable types.
Recommended for: Those who often heat large convenience store lunch boxes or pizzas. Those who want to minimize cleaning effort.
[Most Important Selection Point 2] Hertz-free? Absolutely essential if there’s a possibility of moving!
After the table type, the next thing you must check is the compatibility with “power frequency (Hertz).” This is an extremely important check item, especially for those who may move, as overlooking it could lead to the worst-case scenario of “buying something you can’t use.”
The frequency of household power in Japan is divided into two: “50Hz” in eastern Japan and “60Hz” in western Japan, with the boundary around Fujikawa in Shizuoka Prefecture and Itoigawa in Niigata Prefecture. Some older microwave models can only be used with one of these frequencies, either “50Hz only” or “60Hz only.”
For example, if you buy a “50Hz only” microwave in Tokyo (50Hz area) and then move to Osaka (60Hz area), that microwave won’t function properly and in the worst case, could cause malfunction or fire.
That’s why the mainstream of single-function microwaves sold today are “Hertz-free” models that support both 50Hz and 60Hz frequencies. With these “Hertz-free” microwaves, you can continue to use them with peace of mind anywhere in Japan, regardless of frequency, even if you move.
If there’s even a slight possibility that you might move across eastern and western Japan in the future due to job transfer or further education, make sure to choose a model labeled as “Hertz-free.” This can be said to be an absolute essential condition in choosing a single-function microwave.
Determining usability! Examine the “door opening method” and “operability”
To eliminate small daily stresses, the “door opening method” and “type of operation panel” are surprisingly important, though often overlooked. Choose the most suitable one while imagining your kitchen layout and usage.
Door Opening Method: Determined by installation location
Side-opening: The door opens sideways, pivoting on the left (or right) side, like a refrigerator. You need space on the opening side to open the door, so check if there’s no wall or other appliance on the right side (for left-opening) or left side (for right-opening) of the microwave. Basically, choose a model that opens in the direction easy to open with your dominant hand.
Top-opening: The door opens from top to bottom towards you. It can be installed even without space on the sides, giving more freedom in placement. However, you can’t place items on top when the door is open, so it’s not suitable if you want to place other appliances like toasters on top of the microwave. Also, it can be difficult to take things out if installed in a high position.
Types of Operability: Intuition vs. Accuracy
Dial type: A very simple type where heating time and power are set by turning a dial that clicks. Recommended especially for those who want to use it simply without detailed settings, or for elderly people, as it can be operated intuitively.
Button type: Characterized by the ability to set heating time accurately to the second, like “1 minute 30 seconds,” using a numeric keypad. Suitable for those who want to strictly follow the detailed heating times written on frozen food packages.
There’s no absolute better option. Think about what “ease of use” you seek in a microwave and choose the type that suits you.
