お焼香 is the only word I can think from "oshoko." It literally means "burning a incense." お焼香 is done in a Buddhism funeral as hiro-san above mentioned. The attendants of the funeral take turns to do お焼香 and pray for the dead. In Shinto funeral, they do some other rituals.

お焼香(oshokou)?? It's a incense used in the funeral. We pray for the dead by using it.
