Nichiren Buddhism in the context of "Gohonzon"

East Asian Buddhism or East Asian Mahayana is a collective term for the schools of Mahāyāna Buddhism which developed across East Asia and which rely on the Chinese Buddhist canon. These include the various forms of Chinese, Japanese, Korean, and Vietnamese Buddhism. East Asian Buddhists constitute the numerically largest body of Buddhist traditions in the world, numbering over half of the world's Buddhists.

East Asian forms of Buddhism all derive from the sinicized Buddhist schools which developed during the Han dynasty and the Song dynasty, and therefore are influenced by Chinese culture and philosophy. The spread of Buddhism to East Asia was aided by the trade networks of the Silk Road and the missionary work of generations of Indian and Asian Buddhists. Some of the most influential East Asian traditions include Chan (Zen), Nichiren Buddhism, Pure Land, Huayan, Tiantai, and Chinese Esoteric Buddhism. These schools developed new, uniquely East Asian interpretations of Buddhist texts and focused on the study of Mahayana sutras. According to Paul Williams, this emphasis on the study of the sutras contrasts with the Tibetan Buddhist attitude which sees the sutras as too difficult unless approached through the study of philosophical treatises (shastras).

Buddhism was first established in Japan in the 6th century CE. Most of the Japanese Buddhists belong to new schools of Buddhism which were established in the Kamakura period (1185－1333). During the Edo period (1603–1868), Buddhism was controlled by the feudal Shogunate. The Meiji period (1868–1912) saw a strong response against Buddhism, with persecution and a forced separation between Buddhism and Shinto (Shinbutsu bunri).

The largest sects of Japanese Buddhism are Pure Land Buddhism with 22 million believers, followed by Nichiren Buddhism with 10 million believers, Shingon Buddhism with 5.4 million, Zen Buddhism with 5.3 million, Tendai Buddhism with 2.8 million, and only about 700,000 for the six old schools established in the Nara period (710－794).

The Lotus Sūtra (Sanskrit: Saddharma Puṇḍarīka Sūtram, lit. 'Sūtra on the White Lotus of the True Dharma'; traditional Chinese: 法華經; simplified Chinese: 法华经; pinyin: Fǎhuá jīng; lit. 'Dharma Flower Sutra') is one of the most influential and venerated Buddhist Mahāyāna sūtras. It is the main scripture on which the Chinese Tiantai and its derivative schools--the Japanese Tendai and Nichiren, Korean Cheontae, and Vietnamese Thiên Thai schools of Buddhism--were established. It is also influential for other East Asian Buddhist schools, such as Chan and Zen. According to the British Buddhologist Paul Williams, "For many Buddhists in East Asia since early times, the Lotus Sūtra contains the final teaching of Shakyamuni Buddha—complete and sufficient for salvation." The American Buddhologist Donald S. Lopez Jr. writes that the Lotus Sūtra "is arguably the most famous of all Buddhist texts," presenting "a radical re-vision of both the Buddhist path and of the person of the Buddha."

Two central teachings of the Lotus Sūtra have been very influential for Mahāyāna Buddhism. The first is the doctrine of the One Vehicle, which says that all Buddhist paths and practices lead to Buddhahood and so they are all actually "skillful means" of reaching Buddhahood. The second is the idea that the lifespan of the Buddha is immeasurable, and that therefore, he did not really pass on into final Nirvana (he only appeared to do so as upāya), but is still active teaching the Dharma.

Honnō-ji (本能寺) is a temple of the Nichiren branch of Buddhism located in Kyoto, Japan.

Nichiren (日蓮; Japanese pronunciation: [ɲi.tɕiꜜ.ɾeɴ, ɲiꜜ.tɕi.ɾeɴ], 6 April 1222 – 13 October 1282) was a Japanese Buddhist monk and philosopher of the Kamakura period. His teachings form the basis of Nichiren Buddhism, a unique branch of Japanese Mahayana Buddhism based on the Lotus Sutra.

Nichiren declared that the Lotus Sutra alone contains the highest truth of Buddhism and that it is the only sutra suited for the Age of Dharma Decline. He insisted that the sovereign of Japan and its people should support only this form of Buddhism and eradicate all others, or they would face social collapse and environmental disasters. Nichiren advocated the faithful recitation of the title of the Lotus Sutra, Namu Myōhō Renge Kyō, as the only effective path to Buddhahood in this very life, a path which he saw as accessible to all people regardless of class, education or ability. Nichiren held that Shakyamuni and all other Buddhist deities were manifestations of the Original Eternal Buddha (本仏 Honbutsu) of the Lotus Sutra, which he equated with the Lotus Sutra itself and its title. He also declared that believers of the Lotus Sutra must propagate it even though this would lead to many difficulties and even persecution, which Nichiren understood as a way of "reading" the Lotus Sutra with one's very body. Nichiren believed that the spread of the Lotus Sutra teachings would lead to the creation of a Pure Land on earth.

Enryaku-ji (延暦寺, Enryaku-ji) is a Tendai monastery located on Mount Hiei in Ōtsu, overlooking Kyoto. It was first founded in 788 during the early Heian period (794–1185) by Saichō (767–822), also known as Dengyō Daishi, who introduced the Tendai sect of Mahayana Buddhism to Japan from China. The temple complex has undergone several reconstruction efforts since then, with the most significant (that of the main hall) taking place in 1642 under Tokugawa Iemitsu. Enryaku-ji is the headquarters of the Tendai sect and one of the most significant monasteries in Japanese history. As such, it is part of the UNESCO World Heritage Site "Historic Monuments of Ancient Kyoto (Kyoto, Uji and Otsu Cities)". The founders of Jōdo-shū, Jōdo Shinshū, Sōtō Zen, and Nichiren Buddhism all spent time at the monastery. Enryaku-ji is also the center for the practice of kaihōgyō (aka the "marathon monks").
