I feel the animal Shouichi Kato's message is Eubranchus echizenicus (Baba, 1975). My friend T. Kenji found a similar animal at Omijima, Yamaguchi Prefecture and it was identified as E. echizenicus. Please take a look, http://www.h.do-up.com/home/takayan/takaPage430.htm.
Both look the same to me.

I agree they look the same. I have had another look at Baba's original description of Eubranchus echizenicus and agree that it is most probably this species. Mr Kenji's photo, showing a side view, shows the white on the cerata and the orange-red restricted to the upper half of the rhinophores very clearly. Thanks very much for drawing my attention to this identification. It is a perfect example of how valuable our collaboration on the Forum is. The only easily available published information on this species is the original description, which included a black & white line drawing of the animal. To see photos of living animals makes it so much easier to compare it with similarly coloured, and spotted. species from Japan ans elsewhere.
