Futatsu-doh twin halls are located in front of Taiyuin Mausoleum. Twin halls are connected with passage. This construction style is rare in Japan. You will only see this style in Mt. Hiei and Rinnoji Temple.

Jogyo-doh hall is traditional Japanese style, and image of Amida Nyorai is enshrined in the center of the hall. This hall is for Buddhist training. Priest pray for national peace and people's happiness on the New Year's day. The principal image of Amida Nyorai was made in Heian period. It wears crown and is seated. This shape is rare and precious. Also, God of Matara is enshrined in the hall.

Hokke-doh hall is smaller than Jogyo-doh hall, but they are similar to each other. However, this building is lacquered and more like Chinese style building. The principal image is Fugen Bosatsu, and God of Kishimo-jin
and other Child-Giving Deities are put on the both right and left side.

Although, purposes of those two halls are slightly different, people worship them.
