Answer
The answer is Sōtō, a school of Zen Buddhism founded in Japan by Dōgen Zenji in the 13th century. Sōtō is one of the two major schools of Zen in Japan, alongside Rinzai. It emphasizes the importance of shikantaza, or "just sitting" meditation, as the primary means of reaching enlightenment. Sōtō is known for its simplicity and its focus on everyday life as a path to spiritual awakening.
