There's three more objectives that you need to fulfill in order to complete the Yamatai sidequest:

1. Go to the Cat Shrine (猫神社) towards the west and talk to the miko there. Then "speak" to all of the Nekomatas before talking to the miko again. If you did this right then Dullahan will talk.

2. Defeat the Shirohebi Elder. Just head on over to the Snake Shrine (蛇神社) to the north and you'll soon get a short cutscene showing the younger Shirohebi outside. Head inside and give her the smackdown.

3. The last one is really easy. Go to the  Kitsune Shrine (狐神社) and s imply go inside the small house to the right when you enter the shrine. Luka will comment that no one's there and Dullahan will say that this quest was already done way before Luka arrived.

Now head back to the elder. You should be able to trigger the Four Perverts sidequest after talking to him again after the main Yamatai quest is finished.
