Two Japanese women are feeding voracious silkworms. The large size of the basket filled with leaves clearly shows the enormous appetite of the worms.
After silkworm eggs were hatched in an incubator, the young worms were moved to a feeding room like the one in this image. At first they were fed mulberry leaves that had been made into an ash. Later they were fed on chopped leaves, and eventually full-sized leaves, as seen here.
Feeding was extremely hard work as for thirty days the worms had to be fed the exact right quantity of food six times a day. For the women—as it was women who did the feeding—it was like having rooms full of babies.
The thirty day feeding period was interrupted by four periods of “sleeping” or min. The min lasted for two days, while the feeding periods, called rei, lasted between three to six days. Roughly on the thirtieth day after emerging from the egg, the worms began spinning their cocoons.
Although Bird’s description makes it all look very idyllic and romantic, the silk industry was a very important export business that helped launch Japan on its road to industrialization. As Japan had closed itself off from the outside world for hundreds of years, Japanese businessmen had a hard time finding markets where they could compete after the country opened its borders in the mid-19th century. One industry that succeeded was silk.
This was partly due to plain luck. Just as Japan entered the silk market, the European silk industry had collapsed due to an epidemic of several silkworm diseases resulting in higher prices for silk. Additionally, the Suez Canal opened in 1869 (Meiji 2), dramatically lowering transportation costs from Japan to Europe.
The profits that the Japanese were able to make as a result of these developments, fueled tremendous growth. Raw silk as well as cotton yarn and fabrics, were for a long time Japan’s main source of foreign exchange.
By 1913 (Taisho 2), Japan accounted for no less than 28% of global silk production.3
