The Hattō (Dharma Hall) at Nanzen-ji Temple is a historic building where monks study and preach the teachings of Buddhism. Reconstructed in 1639 during the early Edo period, this Hattō is one of the most important structures symbolizing the dignity of Nanzen-ji. Inside the spacious hall, a statue of Shakyamuni Buddha is enshrined. The Hattō is particularly famous for its large ceiling painting of a dragon, known as the "Dragon Glaring in All Directions." This artwork, painted by Kanō Tan'yū, is so named because the dragon appears to be staring at the viewer from any angle. This ceiling painting is a major attraction at Nanzen-ji, drawing many visitors. Additionally, the Hattō regularly hosts zazen (seated meditation) sessions and Dharma talks, providing visitors with opportunities to experience the spirit of Zen. The Hattō serves not only as an architectural marvel but also plays a crucial role in spreading the teachings of Zen at Nanzen-ji, making it a place of significant cultural and religious value. With its historical background, religious importance, and beautiful ceiling painting, the Hattō at Nanzen-ji is a site of profound impact, leaving a lasting impression on all who visit.
