Okane Seisakusho: The Bamboo-Ruler Workshop in Koka

A bamboo ruler looks quiet on a sewing table. Its scale is easy to take for granted; so is the work needed to put a useful straight measure onto a natural material. Okane Seisakusho’s workshop story gives that familiar object a little more weight.

1. A workshop devoted to measuring in bamboo

Okane Seisakusho is a bamboo-ruler business in Konan, Koka, Shiga, founded in 1948. Its official company page records the manufacture and sale of bamboo rulers and smaller bamboo objects. Okane’s company information. The company’s published range includes centimetre rulers, kanejaku and kujirajaku scales, special-purpose rulers and customised designs. It also supplies name marking and small bamboo objects such as straps and nameplates. Those categories show a wider bamboo specialism than the three ruler sizes represented in our shop. Okane’s own catalogue.

A workshop offering centimetre, kanejaku and kujirajaku rulers is serving different measuring traditions as well as different lengths. Okane’s catalogue makes those categories explicit. You do not have to use every scale to appreciate the point: the same material can carry different kinds of practical knowledge. Okane’s ruler categories.

A marked line on bamboo looks simple because the difficult part has already been done. On the sewing table, you want to find the scale quickly and place it against the work. The shaping, straightening and finishing described in the maker account are the work that makes that ordinary moment possible.

2. The work before a ruler reaches the sewing table

Eight Needles’ published maker account describes more than twenty operations, including shaping, straightening, marking, inking and finishing. Eight Needles’ maker account.

3. A tool that stays in view

There is a particular pleasure in an object whose material remains visible. On a bamboo ruler, the printed scale and the bamboo surface share the same narrow space. Looking closely at the gallery lets you see both. It is a different experience from a tool whose body hides all traces of its material beneath a casing.

The 20cm, 30cm and 40cm choices in our listing let you decide how much ruler you want beside the work. A short length is easy to keep near a small sewing area; a longer length gives a longer reference along a piece of paper or cloth. Check the dimensions on the product page and choose for your own table.
