The Konjikido (金色堂) or 'Golden Hall' is a mausoleum containing the mummified remains of the leaders of the Northern Fujiwara clan who ruled much of northern Japan in the 12th century. It is one of two buildings that survive from the original Chuson-ji temple complex, the other being a sutra repository.

The Konjikido is one of the most beautiful and elaborately decorated buildings in the world. It is made of wood entirely covered with gold leaf decorated with imported mother-of-pearl. It was carefully restored from 1962 to 1968 by a team of specialists. It is a square building measuring five-and-a-half meters on each side and eight meters tall. The interior of the building contains three altars, one for each of the first three Fujiwara lords. Originally there were 33 sculptures inside the temple, eleven on each altar, but now one is missing. Each altar had a seated Amida surrounded by standing Kannon and Seishi, six Jizo and two Niten statues. One Niten figure is missing.

The mummies were last examined in 1950. It is assumed that the mummy of Fujiwara no Kiyohira was placed under the central altar. Fujiwara no Motohira's remains were identified as he is known to have died of a cerebral hemorrhage. His mummy was found under the northwest altar. Fujiwara no Hidehira's remains were found under the southwest altar next to a casket containing the head of his son Fujiwara no Yasuhira who was beheaded in 1189.

The Konjikido formerly sat outdoors in the open air. Later a wooden building was built around it to protect it from the elements. Now it sits in a concrete building behind thick acrylic glass and is only visible from the front.
