Shizuka Toshi (CN20) was constructed within a clearing in Osari Mori, the forest north of Kyuden Doji. It held the Doji Academy, the major dojo of the Doji Courtiers. All the promising Crane courtiers received their training here. Visitors were rarely admitted, and the dojo was so remote that young courtiers in training did not have the chance to shame their clan. It was located within the Kazenmuketsu province.
