Antheraea yamamai, the Japanese silk moth or Japanese oak silkmoth (Japanese: yamamayu(ga) (山繭(蛾)・ヤママユ(ガ)) or tensan (天蚕)) is a moth of the family Saturniidae. It is endemic to east Asia, but has been imported to Europe for tussar silk production and is now found in southeastern Europe, mainly in Austria, northeastern Italy, and the Balkans. It seems to be spreading north and a population has been reported near Deggendorf and Passau in Germany.[1] The species was first described by Félix Édouard Guérin-Méneville in 1861. It has been hybridized artificially with Antheraea polyphemus of North America.[2]

This moth has been cultivated in Japan for more than 1000 years. It produces a naturally white silk but does not dye well, although it is very strong and elastic. It is now very rare and expensive.[3]

The wingspan is 110–150 millimetres (4.3–5.9 in). Adults are on wing from August to September in one generation depending on the location.

The larva mainly feed on Quercus species, but have also been reported on Fagus sylvatica, Castanea sativa, Carpinus, Rosa, and Crataegus.
