"Life in Japan 2023" How to choose a toaster oven and recommended manufacturers!

Toaster ovens are convenient to have, but they are not only single-function ovens, but also come with fans, steam functions, and other features, with prices ranging from 2,000 yen to 30,000 yen. In order to buy the right product for your home, please do your research thoroughly!

Type of Heater

Some toaster ovens are described as "equipped with an electric heating wire heater" or "equipped with a far-infrared heater" or "equipped with graphite" or "quartz tube" as if they have something that other toasters do not, but that is not true. As explained in detail from the viewpoint of thermodynamics in the following article on heaters, almost all heaters sold to the public contain electric heating wires, graphite (graphite) is used as the material for electric heating wires, and all objects on the earth, not just toasters, emit far-infrared radiation.


Fine temperature control

Some have a scale only in increments of 20°C, or the temperature can be adjusted in only a few steps, so we recommend that the temperature be adjustable in fine increments.

Ease of cleaning

A type that can slide off the saucer is convenient because it is easy to clean.

Size of main unit

The most common toaster is large enough to hold two slices of bread, but some toasters are large enough to hold four slices of bread. 25-cm pizzas and other items can also be baked, which broadens the range of dishes. However, it requires more space than the size of the unit because of the high heat emitted.

The photo shows our house. It looks like there is a gap, but you need to leave a gap of about 10 cm from front to back and left to right, so even a toaster large enough to hold two slices of bread does not have that much room. (Microwave oven on the left, toaster oven on the right)


Other Functions

Some products are sold as convection ovens, which have a fan inside to circulate the heat inside the toaster. However, we believe this is unnecessary because a toaster is a small space and far-infrared rays are reflected inside the toaster, so heat can be circulated without a fan.

Steam functions of lesser importance are also excluded from the comparison. In particular, there are rare toasters with a hole in the top that allows water to drip down and evaporate over the heater, which can crack if there is a sudden change in temperature in the heater.

The Zojirushi EQ-SB22 is the best choice, as it has a wide temperature range and a 30-minute timer, but costs only 3,000 yen less than the Yamazen, but if a single function is enough for you, we recommend the Yamazen YTS-C101.


4 slices of bread
model number ET-GU30 YTC-FC123

timer 30 min. 15 min.

Both Zojirushi and Yamazen have the same temperature and timer as a toaster for two slices of bread, so we recommend the Zojirushi ET-GU30 as the best choice here as well. However, for those for whom a single function is sufficient, we recommend Yamazen's YTC-FC123.

I hope the above is helpful.
