Why it made the five

70 kPa, about 115°C, for braises that would otherwise take an evening
Set to finish three to fifteen hours later, with twenty programmes
Three parts to wash each time: lid, inner lid, pot
Right for: Wanting pressure to shorten braising, and cooking ahead for the week.
Not for: Wanting a long list of programmes — there are twenty.
Worth knowing: Only some of the automatic programmes can be set to finish later, and some do not switch to keep-warm when they finish. It is 34.0 cm wide, 27.4 deep and 26.2 tall, so measure the counter.

Know before you buy

All five can be loaded and set to finish later, from three to fifteen hours ahead. That is the whole point: the cooking happens while you are at work.
Pressure cooking reaches above 100°C, so Japanese braises — pork belly kakuni, beef tendon, nikujaga — take a fraction of the time. The pressures here run from 70 to 100 kPa.
Built-in programmes run from 20 to 120. More is not automatically better; what matters is whether the ones you will actually cook are there.
Two machines stir by themselves, which is the difference between a braise and a stir-fry. One does both stirring and pressure.
Washing-up is the thing people underestimate. Panasonic publishes a figure of three parts; most makers publish nothing.
Capacity is sized in Japanese terms — these are 1.6 to 2.6 litres of working volume, meant for a Japanese kitchen counter rather than a large family.

Questions visitors ask

What is the difference between an electric pressure cooker and a Hot Cook?

A pressure cooker gets above 100°C, so simmering takes less time — Panasonic’s NF-PC400 runs at 70 kPa, about 115°C. Sharp’s Healsio Hot Cook does not pressurise at all; it is a no-water cooker that stirs for you with a paddle unit. Panasonic’s NF-AC1000 is the one machine that does both, stirring from the base and pressurising to 100 kPa.

Which suits a single person?

The smallest is Siroca’s SP-MC2D151, sized for one to three with 2.4 L to the brim and 1.6 L of working volume. Sharp’s Hot Cook KN-HW16K and KN-MN16H are also 1.6 L, which Sharp reckons at two to four portions of no-water curry. If you want to cook ahead as well, the 2.6 L Panasonic NF-PC400 is the larger option.

What does running one cost?

Assuming an hour of continuous heating at the rated wattage and ¥31 per kWh: the 600 W Hot Cook is about ¥18.6, the 800 W NF-PC400 and KPC-MB3 about ¥24.8, and the 1290 W NF-AC1000 about ¥40.0. Real cooking is less, because the element cycles off.

Anything to watch with the timed cooking?

None of them can time every programme. T-fal’s Cook4me allows up to fifteen hours but not on its built-in recipes, only on manual settings. Panasonic says ‘some automatic programmes only’. Iris Ohyama’s KPC-MB3 runs from an hour and a half to twelve hours, or from an hour for curry. Check the specific dish you plan to come home to.

Will it work when I move out of Japan?

No — these run on Japanese 100 V mains at 50/60 Hz. They are for a kitchen here. If you are in Japan for a year or more and cooking Japanese food on weekday evenings, one of these replaces a good deal of standing over a pot.

How much counter space do these need?

More than you think, and Japanese kitchens are small. The NF-PC400 is 34.0 × 27.4 × 26.2 cm, and the NF-AC1000 weighs about 8.2 kg, so it stays where you put it. The Siroca at 24 × 26 cm is the one that fits a one-room flat’s kitchen.
