Hoshi Matsuri (æÂÂã¾ã¤ãÂÂ, "Star Festival") is a Buddhist ritual performed on occasions such as the lunar New Year, the beginning of spring (risshun), setsubun, or the winter solstice. Its purpose is to eliminate various disasters that may occur throughout the world or within the nation, as well as misfortunes affecting individuals. It is also known as Hoshi Kuyà  (æÂÂä¾Âé¤Â, "Star Offering"), Hoshiku (æÂÂä¾Â), or the Hokuto-hà  (Ã¥ÂÂæÂÂæ³Â, "Northern Dipper Rite").
In Esoteric Buddhism, which belongs to the later phase of MahÃÂyÃÂna teachings, Hoshi Matsuri is a ritual centered on deities such as Ekaká¹£ara-uá¹£á¹Âëṣacakra (ä¸ÂÃ¥ÂÂéÂÂ輪ä»Âé Â, ichiji kinrin butchà Â; lit. "One-Syllable Golden Wheel Buddha Uá¹£á¹Âëṣa"), a title given to Dainichi Kinrin (大æÂ¥éÂÂ輪; "MahÃÂvairocana as the Golden Wheel") or Shaka Kinrin (éÂÂ迦éÂÂ輪, "à ÂÃÂkyamuni as the Golden Wheel") who is the main deity in the Star Mandala (æÂÂæÂ¼è¼羠, hoshi Mandara); Seven-Star CintÃÂmaá¹Âicakra (ä¸ÂæÂÂå¦ÂæÂÂ輪観é³) in the Seven-Star Nyoirin Mandala (ä¸ÂæÂÂå¦ÂæÂÂ輪æÂ¼è¼羠); or Sudá¹Âá¹£á¹Âi Bodhisattva (å¦Âè¦Âè©è©) in the Myà Âken Mandala (å¦Âè¦ÂæÂ¼è¼羠).
The ritual is a form of esoteric practice and ceremony intended to worship the year's principal stars, as well as each individual's guardian star of the year (å½Âå¹´æÂÂ, tà Ânenjà Â) and birth star (æÂŒÂ½æÂÂ, honmyà Âjà Â).
Although the term âÂÂhonmyà Âjà Ââ is also used in Nine Star Ki astrology (ä¹ÂæÂÂæ°Âå¦, kyà «sei kigaku), in this context it refers not to the nine stars of that system, but rather to the seven stars of the Big Dipper and the Navagraha.
In Esoteric Buddhist astrology, as represented by the Star Mandala (æÂÂæÂ¼è¼羠, hoshi mandara), the practice is founded on two main pillars: esoteric ritual practice and esoteric astronomy and astrology. One of the nine planets, or one of the seven stars of the Big Dipper, is designated as a personâÂÂs birth star, which governs their destiny.
The star that governs a personâÂÂs fate for a given year is also called the Tà Ânen Zokushà  (å½Âå¹´å±ÂæÂÂ, "Yearly Governing Star"). These stars are venerated through ritual offerings to pray for personal happiness throughout the year and to ward off misfortunes.
