Toshiba Mini IH Rice Cooker | RC-DZ4K (0.45L)
The Toshiba RC-DZ4K is a 0.45L mini IH rice cooker made in Japan. It cooks up to 2.5 cups of rice, and Toshiba suggests it for about 1–3 people. Its 5mm 'diamond binchotan' inner pot has a wing-shaped (hagama-style) profile and a wave-patterned base, with binchotan far-infrared heating from all around. There are 3 rice types — white, pre-washed and mixed grains — and 7 cooking modes: Regular, Delicious, Hard, Sticky, Quick, Mixed and Congee. The body is finished in champagne gold, and the control panel is labelled in English and Simplified Chinese.
Product Features:
- 0.45L Mini Capacity: Cooks up to 2.5 cups of rice (measured with the 180ml cup supplied); Toshiba suggests 1–3 people. A 90ml half cup is also included for very small portions.
- 5mm 'Diamond Binchotan' Inner Pot: Diamond titanium coating inside and binchotan far-infrared coating outside — hard-wearing, quick to conduct heat and non-stick.
- Wing-Shaped Pot: The tall, curved wall keeps the upper part of the pot boiling, while a flat copper rim locks in heat and strengthens convection.
- 360° Binchotan Far-Infrared Heating: Heat is maintained above the inner lid and below the pot base, together with induction heating.
- Wave-Patterned Pot Base: The rippled base produces stronger bubbling and convection, so the rice heats more evenly.
- 3 Rice Types, 7 Cooking Modes: White, pre-washed and mixed-grain/germ rice; Regular, Delicious, Hard, Sticky, Quick, Mixed and Congee.
- Keep Warm and Timer: White rice can be kept warm for up to 24 hours; two memory timers (TIMER 1/2) up to 14 hours ahead.
- Made in Japan: The control panel is marked 'MADE IN JAPAN'.

Cleaning and Maintenance:
- Unplug the cooker and let it cool before cleaning to avoid burns. Never rinse the main body under the tap, and keep the power plug and cord away from water.
- After each use, wash the inner pot, inner lid, steam vent and rice scoop with a sponge and mild kitchen washing-up liquid, rinse, wipe dry with a clean cloth and leave to dry thoroughly. Wash the measuring cup and scoop holder when they get dirty.
- Do not use a dishwasher or dish dryer, and avoid any cleaner other than mild washing-up liquid — no thinners, alcohol, scouring powder, bleach, scrubbing brushes or melamine sponges.
- To protect the non-stick coating, do not use the inner pot as a washing-up bowl, do not put vinegar in it, do not use metal ladles or whisks, and do not scrape it hard with the rice scoop.
- Never heat the inner pot on a gas hob or induction hob, or in a microwave.
- Do not keep rice warm after cooking it with seasonings (for example mixed rice); wash the inner pot and inner lid promptly to prevent rust and odours.
- The inner lid gasket and body gasket cannot be removed, so please do not pull on them; wipe away any dirt or rice grains carefully.
- Wipe the outside, the inside of the outer lid and the heating plate with a well-wrung damp cloth. If a temperature sensor gets dirty, rub it lightly with fine sandpaper (about No. 600) and wipe with a well-wrung cloth. Clear dust from the air inlet and outlet on the base about once a month.
- If odours build up, run the 'cleaning by boiling' cycle described in the manual (about once a week): fill the inner pot with water only, up to level 1 on the 'White rice' scale, start a white rice cycle, press OFF once it switches to Keep Warm, then clean and dry the parts when cool. Never add detergent or anything else, and do not repeat the cycle back to back.
Storage Method:
- Make sure the inner pot, inner lid and steam vent are completely dry and correctly refitted before putting the cooker away.
- Store in a dry, well-ventilated place away from direct sunlight and cooking-oil splashes, which can discolour or warp the body.
- Unplug the cooker when not in use, and keep the measuring cup, rice scoop and other accessories together with it.

The RC-DZ4K cooks up to 2.5 cups of uncooked rice (measured with the 180ml cup supplied), and Toshiba suggests it for about 1–3 people. A 90ml half cup is included, which makes it easy to cook as little as half a cup.
No. The RC-DZ4K is designed purely for rice: it has 3 rice types (white, pre-washed and mixed grains) and 7 cooking modes (Regular, Delicious, Hard, Sticky, Quick, Mixed and Congee), but no Steam, Cake or Soup programme.
According to Toshiba, the inner pot has a tall, curved wall that keeps the upper part of the pot boiling, with a flat copper rim that locks in heat and strengthens convection — modelled on a traditional hagama pot cooked over a stove.
The keys and display are labelled in English and Simplified Chinese — for example RICE, MENU, CONGEE, KEEP WARM/REHEAT, TIMER, START and OFF/CANCEL. Toshiba's owner's manual is available in Chinese and English.
It is rated at 220V, 50/60Hz, which suits household mains in Hong Kong, Macau, the UK, the EU, Australia and New Zealand. It has an HK/UK Type G 3-pin plug, and a free adapter for your delivery country is included — Type I for Australia and New Zealand, Type E/F for the EU. No step-down transformer is required. It is not suitable for Taiwan's standard 110V household supply.
