To conduct national religious services, its original primary role, construction of Hasshinden (eight shrines) was proposed within Jingikan (until then, himorogi - a temporarily erected sacred space or "altar" used as a locus of worship, was built each time a religious ritual was conducted).
また、神祇官の本来的な職掌である国営の祭祀を行う為の八神殿の造営が神祇官内で提案された（それまでは神籬を立てて臨時の祭場としていた）。
