Sex Toys for Women’s Pleasure in the Bedroom (閨中女悦笑道具)
Summer: Sea-cucumber Ring, Jewel Balls, Small Dildo (夏: 海鼠の輪, 琳の玉, せうがた )
c. 1822

One of the consistent features of Japanese shunga is the concern to give pleasure during love-making and there were in fact special sellers of sex toys and sex medications in the later Edo period (1600-1868).

Summer shows a ring of sea-cucumber (namako) worn on the penis to make the glans swell bigger, ‘revolving jewels’ (rin no tama) to be placed inside the vagina and a small-sized dildo to be used by virgins.
