epeatedly into the paper suspension in a<br />

particular rhythm, so that the fibres are<br />

distributed uniformly.<br />

One of the secrets of Washi production is<br />

adding Neri to the paste. This viscous<br />

root sap from the Japanese hibiscus<br />

plant links the paper fibres together, improves<br />

sheet formation and permits wet<br />

sheets to be stacked. The sheets are<br />

dried by pressing and then individually<br />

brushed on to Gingko wood boards. During<br />

the drying process it is this wood that<br />

gives paper its special gloss, an effect<br />

that becomes stronger as the paper ages.<br />

Washi is never bleached unless by exposure<br />

to natural sunlight. The fibres get<br />

their colour solely from the washing and<br />

cleaning processes.<br />

<strong>Paper</strong>making by this method is a burdensome<br />

task. Those involved have to work<br />

in a constant stooped or standing position<br />

for many hours with their hands in<br />

icy water. To master each step in the<br />

process, budding papermakers need four<br />

to six years of training. Although wholesalers<br />

have to pay as much as 80 Euro<br />

for one single sheet of this paper, the<br />

employees hardly ever earn more than 8<br />

Euro per hour. This is one of the reasons<br />

why traditional Japanese small-scale craft<br />

trades have had difficulty for some years<br />

in recruiting young people – despite a lot<br />

of advertising for this profession through<br />

job centres and the visits to schools by<br />

master papermakers, and despite exhibitions<br />

in museums and even theme parks<br />

on the subject of papermaking.<br />

In many regions the traditional papermakers<br />

have had to become highly specialized<br />

in order to outperform industrial<br />

products and locate market niches. In the<br />

Gifu Prefecture, for example, the emphasis<br />

is on “Amime” paper: This networkstyle<br />

Washi is created by water jets perforating<br />

the fibres on the bamboo screen.<br />

This paper is mainly used for decorative<br />

purposes.<br />

Hosho paper is particularly thick and<br />

soft. In the Echizen region this grade was<br />

used to produce Japan’s first national<br />

paper money, because it does not shrink<br />

and is resistant to tearing. Nowadays it is<br />

67<br />

mainly used for wood etchings. Several<br />

famous painters, for example Taikan<br />

Yokoyama, order large-format Washi<br />

sheets from Echizen. They use them for<br />

Sumi-e (watercolour paintings) and calligraphy.<br />

The museum in Imadate, which<br />

is also located in the Echizen region, contains<br />

the world’s largest hand-skimmed<br />

sheet of paper: 7.1 x 4.3 meters – over<br />

30 square metres of Washi in a single<br />

piece.<br />

Of course, it was not a Goddess but<br />

Korean monks who took the art of papermaking<br />

to Japan. The Japanese Emperors<br />

invited the first monks over from the<br />

Korean peninsula in the 5th century, because<br />

they wished to distribute Buddha’s<br />

transcripts on paper all over the country.<br />

The common people were encouraged to<br />

grow mulberry trees to ensure an adequate<br />

supply of raw material. In the<br />

eighth century the Japanese began to refine<br />

the Korean technology when they<br />

discovered Gampi as a raw material, a<br />

plant indigenous to Japan. Gampi fibres<br />

are noted for their exceptional fineness<br />

and natural viscosity. With the aid of this<br />
