Japan is a country where the Lotus Sūtra should be spread exclusively, in the same manner that the Kingdom of Śrāvastī in India was a country where Mahāyāna teachings were spread solely. In India, some areas were exclusively Hinayāna, others were exclusively Mahāyāna, and still others were Hinayāna and Mahāyāna simultaneously. Japan is a country exclusively for Mahāyāna teachings. Of the Mahāyāna teachings, especially the true Mahāyāna of the Lotus Sūtra should be spread in Japan (as recorded in such writings as the Treatise on the Stages of Yoga Practices; the Postscript to Translating the Lotus Sūtra by Sêng-chao; Biography of Prince Shōtoku; Grand Master Dengȳö’s The Outstanding Principles of the Lotus Sūtra and Treatise on the Protection of the Nation; and Comprehensive Interpretations by Venerable Annen). Thus, properly understanding that Japan is a country where the Lotus Sūtra should be spread is to truly understand the country.
