Amida-do is where the statue of Amida looking back is enshrined, moved here from Osaka in 1607. The Looking-back Amida may be prayed from either sides. On the ceilings, hundreds of flowers are depicted.
The Amida-do was built 400 years ago. In september 2006 a restoration work started, and apparently it finished on October 24, 2007 - few days before I was there... lucky me this time.
