Lonely Pearl was an unremarkable geisha house in the Samurai Quarter of Toshi no Naishou. The unremarkable building with white walls and a black tile roof, had an interior richly and intricately decorated. It was supposedly built by the place in the river where a fisherman found a pearl, the only one in his life as pearl-diver. The seven meeting rooms of the Lonely Pearl were themed respectively after the four seasons, the Sun, the Moon, and the stars. Each rom had its own geisha.
