Tosa school
The sits to the west of the Shishin-den, facing east. It, too, has a hipped and gabled roof, and is primarily cypress wood. Originally a place where the Emperor would conduct his own personal affairs, the Seiryō-den was later used for various gatherings and meetings as well. In the center is an area where the Emperor would rest, and on the east side of the hall, an area of two tatami was set aside for dignitaries and aristocrats to sit. Here was where the Emperor could conduct formal affairs. On the north side of the hall was an enclosed area where the Emperor would sleep at night; later, Emperors began to use the official residence. The west side was set aside for the Emperor's breakfasts, and also contained the lavatories, while the south side was used by the keeper of the Imperial Archives. This area contained paintings by the masters of the Tosa school, and just outside, various rare bamboos were planted.
