Japanese techniques · professional vegetable preparation
How paper-thin daikon sheets, fine strips and vegetable nets are created, why the lateral movement of the blade matters and which professional slicer to choose.
A rotary vegetable slicer transforms a firm cylindrical piece of vegetable into a long continuous sheet. The principle is simple: the ingredient rotates against a sharp blade, much like material being turned on a lathe. Professional Japanese machines, however, add precise guidance, stable fixing and, on selected models, lateral blade movement designed to approximate the result achieved by an experienced chef working with a knife.
It is not only about eye-catching decorations. An even cut affects appearance, texture, marinating and the way the ingredient folds, rolls or behaves on the plate. The CHIBA Vegg-Q and CHIBA Tsumataro models are based on the same fundamental principle but address different needs.
Katsura-muki: when vegetables become a continuous sheet
Katsura-muki is a Japanese technique in which a cylindrically shaped vegetable – most often daikon radish – is rotated in the hand while a sharp knife gradually separates a long, very thin strip from it. The chef must simultaneously control the thickness, pressure, blade angle and even rotation of the ingredient.
Performing it by hand is one of the skills associated with professional Japanese cuisine. The result can be used as a wrapper for rolls, the basis of a decoration, a delicate side dish or an intermediate step before further cutting into thin strips. Every change in pressure is immediately visible in the quality of the cut: the strip may ripple, become thinner or tear.
Why is an ordinary peeler not enough?
A conventional peeler creates short, narrow strips and follows the surface of the ingredient. A rotary slicer guides the vegetable along a fixed axis and creates a continuous wide sheet with controlled thickness – a completely different type of preparation.
From craftsmanship to repeatable results
Professional kitchens need not only craftsmanship but also speed and repeatability. Manual katsura-muki is an impressive technique, but mastering it requires extensive training. When preparing larger quantities of garnishes, it is also important for every sheet to have a similar thickness and for the work not to place unnecessary strain on the chef's hands.
Rotary slicers transfer the basic movement into a mechanical system: the vegetable is fixed on an axis, rotated against the blade with a crank and the emerging strip is continuously separated. The advantage is not replacing a chef's skill, but making it possible to prepare a uniform base for further work more quickly and with less waste.
CHIBA KOGYOSHO: from moulds to professional kitchen machines
The history of CHIBA KOGYOSHO CO., LTD. began in May 1964 in Funabashi, Chiba Prefecture. Founder Mitsuo Nagashima originally focused on manufacturing plastic moulds. The business was incorporated in October 1969 and in 1976 began manufacturing and selling professional kitchen equipment.
Development gradually shifted toward specialised slicers for gastronomy. In 1986 the company began manufacturing a cabbage slicer and in November 1989 it started developing and selling the Tsumataro model. Manual and electric devices for fine vegetable cuts, spring onion slicers, graters and other tools followed. The manufacturer thus combines experience in precision component forming, plastic injection moulding and the construction of professional kitchen equipment.

How the lateral blade movement works
On the Vegg-Q and Tsumataro models, the blade simultaneously moves from side to side while the crank is turned. The manufacturer describes this mechanism as a way of approximating a knife-guided cut. The blade therefore does not merely press into the ingredient at one fixed point but performs a gentle slicing movement.
The practical result is a smoother surface with a characteristic sheen. This is particularly important for sheets intended for direct serving, because the structure of the cut affects both the appearance and delicacy of the finished strip.
CHIBA Vegg-Q: specialist for wide sheets
CHIBA Vegg-Q focuses primarily on efficient rotary processing of daikon and other firm vegetables using the katsura-muki technique. It creates a continuous sheet approximately 0.5 mm thick and handles a working width of up to 180 mm.
An ingredient with a maximum diameter of 100 mm is stabilised during use by a tubular element. Thanks to its wide capacity, Vegg-Q is suitable for vegetable rolls, wraps, layered appetisers, sashimi accompaniments and creative plating.
Wide continuous sheet
A working width of up to 180 mm provides plenty of material for rolling and further shaping.
One main focus
Vegg-Q is suitable for customers who primarily need high-quality and efficient katsura-muki.
No electric power
You control the cutting speed manually and the device can be used without connection to the mains.
CHIBA Tsumataro: four techniques in one machine
CHIBA Tsumataro is a more versatile professional station. In addition to katsura-muki, it can prepare fine strips and two types of net cut. The manufacturer equips it with four adapters for katsura-muki, garnish, nageami and odoriami.
The basic katsura-muki thickness is 0.5 mm. The cut can be adjusted using the supplied 0.3 mm adjustment spacers. Standard fine strips are approximately 0.8 mm; according to the manufacturer, a finer 0.6 mm version is available as optional equipment. The maximum ingredient diameter is 100 mm and the working width is 120 mm.
| Technique | Result | Use |
|---|---|---|
| Katsura-muki | Long thin sheet | Rolls, wraps, layers and decorations |
| Garnish | Very fine strips | Sashimi accompaniments, salads and garnishes |

Simple recommendation
Choose Vegg-Q if your main goal is a wide, smooth sheet of daikon. Choose Tsumataro if you want to make fine strips and two types of decorative nets in addition to sheets.
Which vegetables work best
Firm, fresh and regularly shaped ingredients are the easiest to process. Daikon is the traditional choice, but depending on the desired result, cucumber, carrot or another firm vegetable that can be safely shaped into a cylindrical piece matching the capacity of the device can also be used.
- Daikon: wide sheets, fine strips and sashimi decorations.
- Cucumber: thin wraps, rolls and fresh decorations.
- Carrot: colourful strips and smaller decorative elements.
- Potatoes: depending on the cut design, creative net cuts can be used for fried decorations; always work safely and adapt the result to the recipe.
How to achieve a clean, continuous cut
- Choose a fresh ingredient. Wilted or hollow vegetables may tear.
- Shape it into a straight cylinder. The ends must be cut perpendicular so that the vegetable is secured on the axis.
- Check the blade and adapter. A damaged or incorrectly seated edge reduces cutting quality.
- Turn smoothly. Irregular speed and excessive pressure can break the sheet.
- Move the finished strip aside continuously. This prevents tangling and damage.
Safety and maintenance
Rotary slicers work with extremely sharp blades and attachments. The device must stand on a firm, level surface and the ingredient must be secured correctly. Do not place your fingers in the blade area during operation or while removing the finished sheet.
After use, remove vegetable residue, rinse the washable parts by hand and dry them thoroughly. Do not touch the cutting edges when removing the adapters. Aggressive cleaning products and wire scourers may damage the surface. Deteriorating cutting quality, tearing of the sheet or visible damage are signs that the blade should be inspected and, if necessary, replaced.

Frequently asked questions about rotary slicers
What is a rotary vegetable slicer?
A mechanical device that rotates a secured vegetable against a blade and creates a long continuous sheet or other subsequent shapes.
What does katsura-muki mean?
A Japanese technique for cutting cylindrical vegetables into a long, very thin strip. Traditionally it is performed with a sharp knife; a rotary slicer mechanises its principle.
Why does the blade move from side to side?
The lateral movement creates a slicing action similar to guiding a knife and helps achieve a smooth, glossy surface on the sheet.
What is the main difference between Vegg-Q and Tsumataro?
Vegg-Q focuses on wide katsura-muki sheets. Tsumataro additionally prepares fine strips and two types of decorative nets.
How wide a sheet does Vegg-Q create?
The maximum working width is 180 mm and the katsura-muki thickness is approximately 0.5 mm.
Which adapters does Tsumataro include?
Four adapters for katsura-muki, fine strips, nageami and odoriami.
What are nageami and odoriami?
Two types of decorative net cut. Nageami creates a finer, more regular net, while odoriami creates a looser and more three-dimensional structure.
Which vegetables are most suitable?
Primarily fresh daikon and other firm, regularly shaped vegetables that can be safely trimmed and secured on the axis.
Do the slicers require electricity?
No. Both Vegg-Q and Tsumataro are manual mechanical devices powered by turning a crank.
Are they also suitable for home cooks?
Yes, if they regularly prepare Japanese dishes or creative vegetable decorations. The dimensions and capabilities of the devices, however, are also suitable for professional operations.
How is a rotary slicer cleaned?
After use, remove food residue, carefully rinse the washable parts and dry everything thoroughly. Do not touch the cutting edges.
When is it time to replace the blade?
When the sheet starts tearing, the surface loses its smoothness, cutting requires more force or the edge is visibly damaged.
