From Japanese people, I have the impression that they've largely given up on microwaves and toaster ovens, as inconvenient and space-wasting. Having an oven in a Japanese home is extremely rare, being regarded as professional bakery equipment.

Instead, they have a "deshi rehhhn-ji", which literally translates to "electric range". This will confuse people for whom "the range" is the thing you can place multiple pots and pans on to cook simultaneousely.

But a denshi rehhhn-ji actually is more like a combination toaster oven plus microwave with a single shared compartment, designed to use infrared and microwave power simultaneously. Attempts to market these in USA over 14 years ago failed, seemingly due to high prices and consumers' preconception that ovens, toasters, and microwaves are fundamentally separate devices. However, I've recently seen at a Target store in USA three different combination devices that may be similar, from different companies. Their marketing at that store was like "combination air fryer and microwave!" and "combination microwave and broiler!".

deshi reenji …but that the double 'e' is not an English "long e" but rather more like an English "short e" of double length.
