This sea slug, Herviella mietta doesn't seem to be reported on the Forum from Japan, so here is a Japanese individual. It was discovered under a stone in shallow water in a sheltered bay.
There were many sea anemones in the neighborhood. I am very interested about the distribution of Herviella mietta. I am happy if these reports are useful for your research.

Yes I am sure this is Herviella mietta. As far as I know the only records we have of it are from Enewetak Atoll in the Marshall Ids and from the Hawaiian Ids, so your find in Japan is an interesting extension to its known distribution. I am also interested in your description of it being in an area with many sea anemones. As I discuss in the Fact Sheet, there are possible observations of it in Hawaii feeding on a sea anemone, which is of interest because aeolids of the family Glaucidae are not known to feed on sea anemones. So if you get a chance to observe this species again it might be worth 'introducing' it to an anemone and seeing if it takes any interest. There is not much chance it will start feeding, but it is always worth a try.
