Introduction to the Four Seasons Auditorium (Master Yuan San Hall): Located near Yokokawa Central Hall, this is the residence of Liang Yuan (Master Yuan San), the ancestor who inherited the resurgence of the Tiantai Sect and the Cihui Master. It was called the "Four Seasons Auditorium" because in the fourth year of Yasuo's reign, according to the order of Emperor Murakami, discussions on the Lotus Sutra were held here in spring, summer, autumn and winter.
