Shingon in the context of "Iṣṭa-devatā (Buddhism)"

Japanese Buddhist architecture is the architecture of Buddhist temples in Japan, consisting of locally developed variants of architectural styles born in China. After Buddhism arrived from the continent via the Three Kingdoms of Korea in the 6th century, an effort was initially made to reproduce the original buildings as faithfully as possible, but gradually local versions of continental styles were developed both to meet Japanese tastes and to solve problems posed by local weather, which is more rainy and humid than in China.

The first Buddhist sects were Nara's six Nanto Rokushū (南都六宗, Nara six sects), followed during the Heian period by Kyoto's Shingon and Tendai. Later, during the Kamakura period, in Kamakura were born the Jōdo and the native Japanese sect Nichiren-shū. At roughly the same time, Zen Buddhism arrived from China, strongly influencing all other sects in many ways, including in architecture. The social composition of Buddhism's followers also changed radically with time. Beginning as an elite religion, it slowly spread from the nobility to warriors and merchants, and finally to the population at large. On the technical side, new woodworking tools like the framed pit saw and the plane allowed new architectural solutions.

Kongōbu-ji (金剛峯寺) is the ecclesiastic head temple of Kōyasan Shingon Buddhism, located on Mount Kōya (高野山, Kōya-san), Wakayama Prefecture, Japan. Its name means Temple of the Diamond Mountain Peak. It is part of the "Sacred Sites and Pilgrimage Routes in the Kii Mountain Range" UNESCO World Heritage Site.

The temple was first constructed as Seigan-ji Temple in 1593 by Toyotomi Hideyoshi on the death of his mother, rebuilt in 1861, and given its present name in 1869. It contains many sliding screen doors painted by Kanō Tanyū (1602-1674) and members of the Kyoto Kanō school.

Yixing (Chinese: 一行; pinyin: Yīxíng; Wade–Giles: I-Hsing, 683–727) was a Buddhist monk of the Tang dynasty, recognized for his accomplishments as an astronomer, a reformer of the calendar system, a specialist in the Yijing (易經), and a distinguished Buddhist figure with expertise in Esoteric Buddhism.

In the realm of secular affairs, Yixing gained prominence for his reforms to the imperial calendar and his construction of a celestial globe featuring a liquid-driven escapement, the first in a long tradition of Chinese astronomical clockworks. Within Buddhist circles, he is particularly remembered for his contributions to the translation of the Mahāvairocana-sūtra and for authoring the authoritative commentary on that scripture, the Darijing shu 大日經疏 (T 1796). Due to his significant activities in both religious and secular spheres, a legendary portrayal of Yixing as a master astrologer and practitioner of astral magic developed during the late Tang period, leading to the attribution of several astrological works to him.

The Vairocanābhisaṃbodhi Sūtra (Vairocana’s Awakening Sutra, Sanskrit: 𑀯𑁃𑀭𑁄𑀘𑀦𑀸𑀪𑀺𑀲𑀁𑀩𑁄𑀥𑀺𑀲𑀽𑀢𑁆𑀭), also known as the Mahāvairocana Tantra (Sanskrit: 𑀫𑀳𑀸𑀯𑁃𑀭𑁄𑀘𑀦𑀢𑀦𑁆; traditional Chinese: 大毘盧遮那成佛神變加持經; ; pinyin: Dà Pílúzhēnà Chéngfó Shénbiàn Jiāchí Jīng; also known as 大日經 Da Ri Jing) is an important Vajrayana Buddhist text composed before 674 CE. The Indian tantric master Buddhaguhya (fl. c.700 CE) classified the text as a caryātantra, and in Tibetan Buddhism it is still considered to be a member of the carya classification. In Japan where it is known as the Mahāvairocana Sūtra (Daibirushana jōbutsu jinpen kajikyō), it is one of two central texts in the Shingon school, along with the Vajrasekhara Sutra. Both are also part of the Tendai school.

Though the text is often called a tantra by later figures (including later Indian commentators), the scripture does not call itself a tantra.
