Kanejaku
Kanejaku is a unit of length in the shakkan system, used mainly in dimensional notation for architecture and tailoring, and it is a scale with a different base length for one shaku than kujira-jaku.

Definition and Overview
Kanejaku is read as "kanejaku" and is a length standard used in the shakkan system. One shaku is approximately 30.3 centimeters, and even today, when the metric system is standard, it can be seen in customary dimensional notation for traditional Japanese tailoring and architecture.
The name is written the same as kanejaku, a tool for measuring right angles, but in a dimensional context it refers to a unit of length. It is not a term that describes fabric fibers, weave structure, or processing methods, and it does not indicate texture or function.
How It Is Used in Apparel
In the apparel field, kanejaku may be referenced for kimono fabric dimensions, bolt dimensions, and customary expressions used when making patterns. In clothing specifications and fabric standards, centimeters or meters are generally used.
In older documents, verbal communication on the production floor, and instructions related to traditional Japanese clothing, shaku-based expressions may remain. In purchase orders, patterns, and inspection standards, it is important to specify which scale is being used, and to standardize to the metric system when necessary.
Differences from Kujirajaku and Points to Confirm
Kanejaku and kujirajaku are both called "shaku," but the length of one shaku differs. Kanejaku is often used in architecture and dressmaking, while kujirajaku is a scale often used for traditional Japanese tailoring and kimono dimensions. Comparing only the number of shaku can lead to dimensional mix-ups.
When checking bolt width, kimono fabric length, or material allowance, do not judge by the unit name "shaku" alone; confirm whether it is kanejaku or kujirajaku, or check the centimeter conversion value. Shrinkage, washing, and sewing precautions should be considered according to the material and processing conditions of the fabric in question, not kanejaku itself.
- List units in centimeters or meters in specifications.
- Check whether the width and garment length of traditional Japanese fabric are written in kujirajaku.
- For old patterns and instruction sheets, compare the scale used at the time of creation with the actual dimensions.
Frequently Asked Questions
How many centimeters is one shaku in kanejaku?
One shaku in kanejaku is approximately 30.3 centimeters. However, the shakkan system also includes other standards such as kujirajaku. When handling numbers for the width of a kimono bolt or kimono fabric length, do not convert using the shaku count alone; always confirm the type of scale used.
How are kanejaku and kujirajaku used differently in apparel?
Kanejaku is often used for measurements in dressmaking and architecture, while kujirajaku is a scale often used for traditional Japanese tailoring and kimono dimensions. Metric units are the basis in current specifications, but when reading customary notation, it is necessary not to confuse the two.
