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.

British travel writer Isabella Lucy Bird (1831–1904), who visited Japan in 1878 (Meiji 11), wrote her sister about the first silk district she visited in Japan1:

Signs of silk culture began to appear in shrubberies of mulberry trees, and white and sulphur yellow cocoons were lying in the sun along the road in flat trays. Numbers of women sat in the fronts of the houses weaving cotton cloth fifteen inches wide, and cotton yarn, mostly imported from England, was being dyed in all the villages—the dye used being a native indigo, the Polygonum tinctorium. Old women were spinning, and young and old usually pursued their avocations with wise-looking babies tucked into the backs of their dresses, and peering cunningly over their shoulders.

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

Hi there -

I’d like to request permission to use this photo in an 6-month exhibition this summer: 70314-0020.

Will you let me know the fee?

Thank you!


i never heard of feeding silkworms on the ash of mulberry leaves. Is there a citation for this? Seems a little contrary to nature as the caterpillars get all their water/hydration from the leaves and ash would not provide this. Maybe a translation thing. I’ve seen lots of weird translation issues in regards to sericulture. There are two great museums for silk- the Silk Center in Yokohama and the newly reconstructed one in Okayama.


and Unbeaten Tracks is a favorite of mine! an interesting viewpoint…



@glennis: That information about the ash actually comes from the back of the stereoview. I did a quick search, but couldn’t find any information right away about what silkworms were fed in their first of five stages. Will research this when I write about sericulture again!

I also love Unbeaten Tracks. Lots of beautiful descriptions, Bird was very observant.
