Shiromine-ji (白峯寺)

Shiromine-ji sits at 280 metres on a forested ridge of the Goshikidai plateau in Kagawa, the eighty-first temple of the Shikoku circuit. Its halls of dark unpainted wood are paired with the imperial mausoleum of Emperor Sutoku, who died in exile here in 1164 and is remembered as one of Japan's three Great Onryō. Pilgrims chant for compassion at the Senju Kannon hall, then walk in silence to the cedar-shaded grave.

Shiromine-ji adjoins something rare on the Shikoku route: the tomb of an emperor who died believing himself wronged. After the Hōgen Rebellion of 1156, the abdicated Emperor Sutoku was exiled to Sanuki and lived out his last years in defeat. He died in 1164. His body was bathed at the Yasoba Spring on Mt. Shiromine, cremated, and entombed in the cedar grove that now lies a short walk from the Daishi-dō. Tradition records him as one of the Three Great Onryō of Japan — vengeful spirits whose pacification became a sustained religious project. Memorial rites for him have been held at Shiramine for centuries, and the proximity colours the whole precinct.

The temple itself is older than the mausoleum. Local tradition holds that Kūkai climbed Mt. Shiromine in 815, buried a wish-fulfilling jewel at the summit, and consecrated the mountain as a Shingon practice site. Decades later his nephew and disciple Enchin (Chishō Daishi) followed and built the formal halls. The principal image is a Senju Kannon, the Thousand-Armed Bodhisattva of compassion. Most surviving structures date to the seventeenth century, when the Takamatsu domain restored the precinct in the Edo period.

The walk to the mausoleum is the part many pilgrims remember. A cedar avenue, mossed stone steps, and the characteristic hush of a forested imperial precinct. The inner gate is administered by the Imperial Household Agency and not entered. From outside it, pilgrims bow once, in silence, and turn back. The pairing of an imperial grief and a Kannon hall produces a meditation difficult to summarise: a vow of compassion that has held a complicated dead man for nearly nine centuries.

A Shingon foundation with imperial associations, repeatedly rebuilt and reformed across twelve centuries.

The founding tradition recounts Kūkai climbing Mt. Shiromine in 815 and burying a wish-fulfilling jewel — a nyoi-hōju — at the summit, consecrating the mountain as a Shingon site. His disciple Enchin (Chishō Daishi) followed and built the formal halls. After the Hōgen Rebellion of 1156, the abdicated Emperor Sutoku was exiled to Sanuki, where he died in 1164. His body was bathed at the Yasoba Spring, cremated, and entombed beside the temple. To pacify his spirit, memorial rites became inseparable from the temple's identity, and from the late twelfth century onward Shiromine-ji functioned as both a Kannon hall and an imperial memorial site.

Shingon Buddhism (Kōyasan / Tōji esoteric tradition), with a parallel imperial-memorial dimension administered jointly by the temple and, in modern times, the Imperial Household Agency.

A ridge temple of the Goshikidai plateau, joined to an imperial mausoleum and steeped in centuries of pacification rite.

What gives Shiromine-ji its weight is not a single feature but a layering: the Shingon esoteric foundation under Kūkai and Enchin; the eight-century memorial cult of Emperor Sutoku; the Edo-period restoration in dark, unpainted wood; the cedar avenue to the imperial tomb. Pilgrims who have walked the previous eighty temples often describe the precinct as one of the quietest on the route. Mist settles in the cedars in the early morning. The bell at the entry is rung once on arrival and once on leaving.

Originally a Shingon mountain practice site established by Kūkai in 815 and developed by Enchin in the late ninth century. After 1164 the temple's purpose expanded to include memorial rites for the spirit of Emperor Sutoku.

The site moved from Shingon mountain hermitage to imperial memorial centre after Sutoku's burial. Edo-period reconstruction under the Takamatsu domain consolidated the present halls. The Imperial Household Agency took administrative responsibility for the mausoleum precinct in the modern period, separating it formally from the temple while leaving the ritual and atmospheric ties intact.

Shikoku 88 ritual at the Main Hall and Daishi-dō, then a quiet walk to the imperial tomb.

Pilgrims follow the standard henro rite at each of the eighty-eight temples. At the Niō Gate, a bow before entering. At the chōzuya, water is poured over the left hand, then the right, then taken to rinse the mouth. At the Main Hall and the Daishi-dō, a candle is lit at the front of the candle-stand, three sticks of incense placed in the censer, a coin dropped, an osamefuda nameslip deposited, and the Heart Sutra (Hannya Shingyō) recited. The Senju Kannon mantra (On bazara taramaki riku) is chanted at the Main Hall and the Kōbō Daishi mantra (Namu Daishi Henjō Kongō) at the Daishi-dō. After the rites, pilgrims receive the nōkyō calligraphy stamp at the temple office.

Daily Shingon liturgy continues at the temple. Memorial services for Emperor Sutoku are held annually. The Imperial Household Agency maintains the mausoleum precinct itself; the temple does not enter it.

If you arrive in the early morning, walk the full circuit of the precinct before chanting at the halls. The cedar avenue to Sutoku's tomb is best approached in silence, with whatever recollection feels honest about exile, defeat, or grief that has not been resolved. Pilgrims often pause at the outer gate of the mausoleum simply to listen.

Cedar approach, dark seventeenth-century halls, a Kannon hall, and the imperial mausoleum a short walk beyond.

Pilgrims arrive most often by car along the Goshikidai Skyline or, less often, on foot from Kokubun-ji on the henro path. The first impression is of unpainted wood gone almost black with age, set among tall cedars that filter the light to a green dim. Standard henro practice is followed at the Main Hall and Daishi-dō: a bow at the gate, hands and mouth purified at the chōzuya, candle and three sticks of incense lit, an osamefuda nameslip dropped, coins offered, the Heart Sutra recited, the Kōbō Daishi mantra sounded. Coastline glints between the trees from certain points along the ridge.

From the Daishi-dō, a path of stone steps and old cedars leads to the Shiramine no Misasagi, the imperial tomb of Emperor Sutoku. The path is short but feels longer. Visitors stop at the outer gate, bow, and do not pass the inner barrier. Most pilgrims describe the visit to the mausoleum as quieter than they expected and harder to leave than they planned.

The temple complex sits on a small saddle of the Goshikidai plateau. The Niō Gate opens onto a stepped approach; Main Hall and Daishi-dō are the central pair. The cedar path to the imperial mausoleum branches to the east, a few minutes' walk. Views of the Seto Inland Sea open from the ridge to the north.

Shiromine-ji is read in several registers — as a Shingon mountain temple, as a memorial centre for an exiled emperor, and as a layered Edo-period institution.

Historians treat Shiromine-ji as a layered site: a ninth-century Shingon mountain temple in the Kūkai-Enchin lineage, recast in the late twelfth century as a memorial centre for the goryō (angry spirit) of Emperor Sutoku, and consolidated in its current Edo-period form under Takamatsu domain patronage.

Local Sanuki tradition treats the entire Goshikidai plateau as an old sacred mountain landscape — one of Kūkai's tutelary ranges — with Shiromine, Negoro and Aomine as a triad of practice peaks.

Within Shingon esoteric reading, the buried wish-fulfilling jewel at Mt. Shiromine functions as a dharmadhātu axis: the mountain itself becomes a relic of the cosmic Buddha Mahāvairocana. In this frame, Sutoku's onryō is gradually transformed, through ritual recitation, from vengeful spirit to protective deity.

The exact location of the original buried wish-fulfilling jewel is undocumented. The political and religious motivations behind the rapid imperial enshrinement of Sutoku — whether genuine fear of curse, dynastic atonement, or both — remain debated.

A ridge temple reached most easily by car from Sakaide, twenty-five to thirty minutes via the Goshikidai Skyline.

By car: roughly 25–30 minutes from JR Sakaide Station via the Goshikidai Skyline. There is no regular public-transport access; pilgrims drive, taxi from Sakaide, or walk the henro path from Temple 80 (Kokubun-ji), a hilly 6.5 km. Combined visits with Negoro-ji along the Goshikidai ridge are common.

Most pilgrims stay in Sakaide or central Takamatsu. There is no shukubō (temple lodging) at Shiromine-ji.
