However, it was considered to be a problem that no permanent shrine was available in Jingikan, so it was decided that a "temporary" shrine should be constructed to enable religious services to be conducted for a while; the construction of this temporary shrine was completed in December of 1869, and the mitamashiro (an object that was worshiped in place of the spirit of the dead) of the Hasshinden, which had been kept by the Shirakawa and Yoshida families since the Hasshinden was abolished in medieval times, was enshrined there.
しかしながら、神祇官に常設の神殿が無いことは問題とされ、当面の間の祭祀を行う「仮」神殿の造営が決定され、明治2年（1869年）12月に仮神殿は完成し、中世の廃絶以来白川・吉田両家で奉斎されていた八神殿の霊代が奉献された。
