Does Shinto prohibits transplants explanted organs from deceased?
In Japan there is only transplantation from living?
I know that In Shinto, the dead body is considered to be impure and dangerous, and thus quite powerful. "In folk belief context, injuring a dead body is a serious crime...," according to E. Namihira in his article, Shinto Concept Concerning the Dead Human Body. "To this day it is difficult to obtain consent from bereaved families for organ donation or dissection for medical education or pathological anatomy. The Japanese regard them all in the sense of injuring a dead body." Families are often concerned that they not injure the itai, the relationship between the dead person and the bereaved people.

You are asking several separate questions:
1 It's true that Shinto consider death is impure. But strictly speaking, Shinto consider "death" is spritually impure which suposed to be purified, physical corpse is not a matter once it purified.
Shinto never prohibits transplants organs from deceased. It's out of Shinto's expected circumstances.
2: There are some transplantation from deceased. Actually, tansplantation from living are minor than that of from dead body.
3:It might be hard to obtain consent, from bereaved, to donate organs. But it's not because Shinto. More likely, it because the concept of Buddhism "reincarnation". Buddhism concept tells, dead men being are still existing in another world. If bereaved pray a lot and treat a dead body and grave respectfully, that dead person would have better living in the another world, and next life. The ancestors sprit would support living people. Physical death is not the complete termination of the the "being". People still feel compassion to the dead, and injuring the body is just like injuring that "being"
