Japanese kitchen tools: the six worth owning, and the ones that are decoration

Japanese kitchen tools have a strong following in the West for one specific reason: most of them do a single job unusually well rather than several jobs adequately. That focus is the whole design philosophy, and it is also the test for whether a given tool is worth importing. Here are the ones that pass.

1. A Japanese knife — the one that changes things

The highest-return purchase in the entire category. Japanese knives use harder steel than Western ones, typically 60–63 HRC against 56–58, which holds a much finer edge. They are ground more acutely, often 15 degrees per side against the German 20, and are noticeably lighter.

The trade-off is real: harder steel is more brittle. A Japanese blade will chip on a bone or a frozen item where a German knife would flex. Treat it as a slicing instrument rather than a cleaver and it will outlast you.

  • Santoku — the general-purpose choice. Shorter and flatter than a chef’s knife, better at chopping than at rocking.
  • Gyuto — the Japanese take on a Western chef’s knife. Buy this if you rock-chop.
  • Nakiri — straight-edged vegetable knife. Startlingly good if you prepare a lot of veg.
  • Petty — a paring and utility knife. The one most people underestimate.

Budget £60–£150 for something genuinely good. Choose stainless-clad unless you are willing to dry carbon steel after every use. Hand wash, dry immediately, never the dishwasher.

2. Whetstone (砥石, toishi)

Buying a Japanese knife without a whetstone is buying a car without fuel. A pull-through sharpener will destroy the edge geometry you paid for. A combination 1000/3000 grit stone covers everything most home cooks need, costs £25–£50, and takes an afternoon to learn. Ten minutes a month afterwards.

3. Suribachi and surikogi — the grooved mortar

A ceramic mortar with a combed interior and a wooden pestle. The ridges grip, so it grinds sesame, spices and nuts faster and more finely than a smooth marble mortar, and it handles small quantities that a food processor simply smears around the bowl. Genuinely better at its job than the Western equivalent, and cheap.

4. Benriner mandoline

The Japanese mandoline is the one professional kitchens actually use: simple, sharp, adjustable, inexpensive. It is also the tool most likely to injure you in any kitchen. Use the guard every time, without exception, including the last slice — especially the last slice.

5. Donabe — the clay pot

A glazed earthenware pot for one-pot cooking at the table. Heats slowly, retains heat exceptionally, and keeps food hot long after the flame is off. Worth owning if you cook communally; largely decorative if you do not. Requires seasoning before first use, and must never be heated empty or moved from hot to cold quickly.

6. Rice cooker — the one appliance

If you eat rice more than twice a week, a Japanese rice cooker is not a luxury. Fuzzy-logic models adjust temperature and timing throughout the cycle rather than simply boiling and switching off, and the difference in the finished grain is not subtle. Buy the correct voltage for your country rather than an imported unit with a transformer.

What to skip

  • Novelty single-purpose gadgets. The egg moulds and rice-shape presses. Photogenic, drawer-bound.
  • Expensive carbon steel as a first knife. Wonderful, and it will rust while you learn.
  • A full knife set. Two good knives beat six mediocre ones. Buy a santoku or gyuto, add a petty, stop.
  • Decorative chopsticks as everyday cutlery. Lacquered gift chopsticks are for looking at. Plain wooden or bamboo ones are what people actually use.
Panel study

We test Japanese housewares with Western cooks. Japanese manufacturers consistently underestimate how much of their advantage is lost to unclear care instructions — a knife that chips because nobody explained the steel produces a bad review, not a returned product.

Questions people ask

Short, direct answers to the questions this topic reliably raises.

Are Japanese knives better than German knives?

They are different rather than universally better. Japanese knives use harder steel and a more acute edge angle, so they cut more cleanly and hold an edge longer, but they are more brittle and can chip on bone or frozen food. German knives are tougher and more forgiving. For slicing and vegetable work, Japanese knives are clearly superior.

What is the best Japanese knife for a beginner?

A stainless-clad santoku in the sixty to one hundred and fifty pound range. Santoku is the general-purpose shape, and stainless cladding avoids the rust maintenance that carbon steel demands. Buy a combination whetstone at the same time, because a pull-through sharpener will ruin the edge geometry.

How do you care for a Japanese knife?

Hand wash and dry immediately after use, never put it in a dishwasher, store it in a block or on a magnetic strip rather than loose in a drawer, and sharpen on a whetstone rather than a pull-through device. Avoid bone, frozen food and hard squash, since the harder steel chips more readily than Western steel.

What is a suribachi used for?

A suribachi is a ceramic mortar with a combed interior used with a wooden pestle to grind sesame seeds, spices and nuts. The ridges grip the ingredients, making it faster and finer than a smooth mortar, and it handles small quantities that a food processor cannot grind effectively.

Is a Japanese rice cooker worth buying?

If you eat rice more than about twice a week, yes. Fuzzy-logic models adjust temperature and timing throughout the cooking cycle rather than simply boiling and switching off, which produces noticeably better texture. Buy a model made for your country voltage rather than importing one with a transformer.
