The Sun Balcony was one of the most notable rooms in Kyuden Seppun, a large chamber exposed to the open air. The Imperial City could be looked on the distant horizon, but after the Fall of Otosan Uchi, this room was enclosed, as were all windows allowing view of the Ruined City. A Seppun artist painted a vast mural on the walls showing the distant city in flames and lines of samurai marching to battle.
