Hoshigamori: The Sacred Worship Point for Mt. Ishizuchi

Perched at an elevation of approximately 820 meters on a mountain ridge in Saijo City, Ehime Prefecture, Hoshigamori (星ヶ森) is one of Japan's most spiritually compelling scenic viewpoints. Designated as a National Scenic Beauty (名勝) in 2017, this sacred site serves as the western worship point (遥拝所, yōhaijo) for Mt. Ishizuchi — the highest peak in western Japan at 1,982 meters — and the inner sanctuary (奥の院) of Yokomineji Temple, the 60th temple on the Shikoku 88 Temple Pilgrimage.

At Hoshigamori, visitors stand before a small but remarkable iron torii gate dating to 1742 and gaze directly southward across a deep valley toward the sacred peaks of Mt. Ishizuchi. The combination of ancient religious architecture, breathtaking mountain panoramas, and centuries of spiritual tradition makes this a truly unforgettable destination for those seeking authentic Japanese cultural experiences beyond the mainstream.

History and Spiritual Significance

The history of Hoshigamori reaches back to the 7th century. According to temple tradition, in the year 651 (Hakuchi 2), the legendary ascetic En no Gyōja was practicing austerities at this very spot when the deity Zaō Gongen appeared near the summit of Mt. Ishizuchi. He carved the deity's image into a rhododendron tree and built a small hall to enshrine it — an act that is considered the founding of Yokomineji Temple itself.

The name "Hoshigamori" (Star Forest) derives from the esoteric Buddhist ritual performed here by Kūkai (Kōbō Daishi), the founder of Shingon Buddhism and one of the most revered figures in Japanese religious history. During the Daidō era (806–810), Kūkai ascended to this ridge and conducted the secret rite of Hoshi Kuyō (Star Offering) — a Shingon Buddhist ceremony in which practitioners pray to the celestial bodies for protection against calamity and for good fortune. It is said that during this practice, Zaō Gongen appeared to Kūkai as well, prompting him to establish the temple grounds and designate the site as a sacred place.

Throughout the centuries, Hoshigamori has remained deeply intertwined with the Ishizuchi mountain faith (石鎚信仰), a distinctive Japanese religious tradition that blends elements of Shugendō mountain asceticism, Shinto, and esoteric Buddhism. The presence of a torii gate — typically associated with Shinto shrines — within the grounds of a Buddhist temple vividly illustrates the syncretic nature of pre-modern Japanese spirituality, known as shinbutsu shūgō (神仏習合).

Why Hoshigamori Is Designated as a National Scenic Beauty

In October 2017, Japan's Agency for Cultural Affairs officially designated Hoshigamori as a National Scenic Beauty under the category of "Scenic Viewpoint" (展望地点). The detailed designation statement describes Hoshigamori as a unique vantage point that has served since the Edo period as a place to worship Mt. Ishizuchi from its northern side, looking south toward the sacred peaks.

The designation specifically recognizes the carefully constructed stone-walled platform (measuring approximately 14.8 meters north-south and 11.6 meters east-west), the historic iron torii gate, and the stone shrine (石龕, sekigan) housing a seated stone statue of Kōbō Daishi. Together, these elements create an outstanding landscape of faith-related scenic beauty that has been maintained and revered for centuries.

Historical documentation supports the site's long significance. The pilgrimage guide "Shikoku Henro Michishirube" (1687) already mentions the iron torii at this location, and the illustrated "Shikoku Henro Meisho Zue" (1800) depicts the torii standing on the ridge saddle with Mt. Ishizuchi in the background. The famous Edo-period explorer Matsuura Takeshirō also illustrated the view in his 1844 travelogue, confirming that this scenic composition has been treasured for centuries.
