Risshō ankoku ron

The Risshō ankoku ron (On Establishing the Correct Teaching for the Peace of the Land) is a tract written by the Japanese Buddhist prophet Nichiren in 1260. Nichiren, a militant Buddhist prophet, concluded that the Lotus Sutra contained the only true Buddhist doctrine suitable for his time. He believed that Japan's calamities, such as epidemics and earthquakes, were a result of the people's adherence to false Buddhist sects instead of the true teachings of the Lotus Sutra.1

The tract argued that if Japan were to accept Nichiren's doctrine as its national faith and banish all other Buddhist sects, the country would find peace. Conversely, he warned that failure to do so would lead to further suffering and even foreign invasion. Nichiren's radical teachings led to his exile multiple times, but he continued to advocate for his beliefs, seeing events like the Mongol embassies to Japan as proof of his prophecies.1
