Overview

Ichinomiya-ji is the eighty-third temple of the Shikoku circuit and the only one historically tied to a province's principal Shinto shrine. It stands immediately beside Tamura Shrine, the Sanuki Ichinomiya, in a Takamatsu suburb. The principal Shō Kannon is said to have been carved by Kūkai in the early ninth century. A small folk shrine in the precinct, the jigoku-no-kama or 'hell pot', preserves a sterner kind of teaching.

Although it sits within an urban Takamatsu suburb, Ichinomiya-ji's compact precinct holds a kind of religious history rarely so legible elsewhere on the route. Until 1679 the temple functioned as the bettō-ji — the administrative Buddhist sister-temple — of Tamura Shrine, the principal Shinto shrine of Sanuki Province. The two were paired institutions, jointly serving the tutelary kami and the Buddhist dharma in a single sacred zone. Under the 1679 reform of Takamatsu domain lord Matsudaira Yoritsune, the auxiliary temple was administratively separated from the shrine — anticipating, by nearly two centuries, the more sweeping Meiji-era separation of Buddhism and Shinto.

The temple's own founding is older than that pairing. Tradition credits the Hossō priest Gien with the original founding in the early 700s, when the temple was named Daihō-in. The monk Gyōki repaired the pagoda between 708 and 715. Kūkai re-established the temple as Shingon between 806 and 810, carving the principal Shō Kannon by his own hand and, by tradition, also a self-portrait statue. Most of the present halls date from a 1701 reconstruction after the Sengoku-period fire of 1574.

For pilgrims today, the visit is short — thirty to forty-five minutes for the temple alone, an hour or so if Tamura Shrine is included — but unusually instructive. Camphor trees, an old precinct, and the immediate adjacency of an old provincial shrine produce an atmosphere where Buddhist and Shinto sacrality intersect. A folk admonition lives here too. The jigoku-no-kama, a small stone shrine in the precinct, is said to rumble with the sound of hell when a person inserts their head; folk tradition warns that the wicked can find their heads stuck. The story is a folk teaching, not canonical doctrine, and is offered with the characteristic Sanuki mix of warmth and edge.

Context And Lineage

An eighth-century Hossō foundation, re-established as Shingon by Kūkai, and historically paired with the senior Shinto shrine of Sanuki Province.

Founded in the early 700s, by tradition, by the Hossō priest Gien as Daihō-in. The monk Gyōki repaired the pagoda between 708 and 715, and from his time the temple administered the adjacent Sanuki Ichinomiya, Tamura Shrine. Kūkai re-established the temple as Shingon between 806 and 810, carving the principal Shō Kannon and, by tradition, a self-portrait statue. The temple was destroyed by fire in 1574 during the Awa Miyoshi–Kōzai conflict and revived by the monk Yūsei Daitoku. The present buildings date primarily from 1701. In 1679, under Matsudaira Yoritsune's reform, the temple was formally separated from Tamura Shrine.

Why This Place Is Sacred

An urban temple compact in scale but exceptional in religious history — a living relic of pre-Meiji shinbutsu shūgō.

Ichinomiya-ji is one of the few Shikoku 88 sites where the layered religious landscape of pre-modern Japan is still clearly readable. The combined visit with Tamura Shrine, only a few minutes away, completes the picture: shrine to the right, temple to the left, both held by the same protective field for centuries. Pilgrims often find that the temple's smaller scale focuses attention. Ancient camphor trees, the modest 1701 halls, and the small folk shrine of the hell pot all sit within easy walking distance of each other.

Originally a Hossō Buddhist temple founded in the early 700s as Daihō-in, then re-established as Shingon by Kūkai in the early ninth century. From an early date the temple administered the adjacent Sanuki Ichinomiya (Tamura Shrine).

After the 1574 fire of the Awa Miyoshi–Kōzai conflict, the temple was revived by the monk Yūsei Daitoku. In 1679, under Matsudaira Yoritsune's domain reform, the auxiliary jingū-ji administrative function ended and Ichinomiya-ji and Tamura Shrine were formally separated. The current halls date from circa 1701.

Traditions And Practice

Standard Shikoku 88 ritual at the Main Hall and Daishi-dō, often combined with a visit to the adjacent Tamura Shrine.

Pilgrims follow the standard henro rite. After a bow at the gate and purification at the chōzuya, a candle is lit and three sticks of incense placed at the Main Hall. An osamefuda nameslip is deposited, a coin offered, the Heart Sutra recited, and the Shō Kannon mantra (On arorikya sowaka) sounded. The same rite is repeated at the Daishi-dō, ending with the Kōbō Daishi mantra. The nōkyō calligraphy stamp is collected afterwards.

Daily Shingon services continue. Pilgrim hospitality at the nōkyō office is unhurried. The small jigoku-no-kama folk shrine is informally attended; visitors approach it on their own.

Plan to visit Tamura Shrine alongside the temple — the two were paired institutions for nearly a thousand years and still illuminate each other. At Tamura, the standard Shinto rite (two bows, two claps, one bow) is observed. Pause at the camphor trees on the way out; their age is part of the precinct's quiet authority.

Shingon Buddhism

Active

Re-established as Shingon by Kūkai in the early ninth century after earlier Hossō and Ritsu phases. Remains Shingon today as a stop on the Shikoku 88.

Historical

Original tradition of the temple under Gien in the early 700s, when it was named Daihō-in.

No longer active at the site.

Shinto (Tamura Shrine — Sanuki Ichinomiya)

Active

The temple historically functioned as the administrative Buddhist sister-temple of Tamura Shrine, the principal shrine of Sanuki Province. The 1679 reform separated the two; pilgrims today often visit both as a paired site.

Experience And Perspectives

A compact precinct, 18th-century halls, ancient camphor, the hell-pot folk shrine, and the senior Sanuki shrine next door.

Pilgrims arrive most often from the Kotoden Kotohira Line, alighting at Busshōzan or Ichinomiya stations and walking five to ten minutes through suburban streets. The Niō Gate opens onto a precinct dense with old trees. The Main Hall and Daishi-dō stand near the centre.

The henro practice is followed at both halls: bow at the gate, hands and mouth purified at the chōzuya, candle and three sticks of incense lit, an osamefuda nameslip dropped, the Heart Sutra recited, and the Shō Kannon mantra (On arorikya sowaka) sounded at the Main Hall. At the Daishi-dō, the Kōbō Daishi mantra closes the rite. The nōkyō stamp is collected at the temple office.

Many pilgrims also visit the small jigoku-no-kama hokora before leaving. It is unimposing and easy to miss. Local tradition says the wicked who put their heads in the stone shrine hear the rumble of hell and may find their heads stuck — a folk admonition rather than a doctrinal teaching, but treated with care. A short walk leads to Tamura Shrine, where the standard Shinto rite (two bows, two claps, one bow) acknowledges the long-paired Sanuki kami.

The Niō Gate fronts the small precinct. Main Hall and Daishi-dō are central. Old camphor trees frame the courtyard. The jigoku-no-kama hokora is small and sits to one side. Tamura Shrine stands a few minutes' walk away.

Ichinomiya-ji is read as a paradigmatic site of pre-modern Buddhist–Shinto pairing — and as a quiet anticipation of the Meiji-era separation.

Ichinomiya-ji is read by historians as a textbook example of jingū-ji (shrine-temple) institutions in pre-modern Japan: a Buddhist temple administering a province's senior Shinto shrine. Its 1679 separation under domain reform anticipates the more sweeping Meiji-era shinbutsu bunri (separation of kami and Buddha) by two centuries.

Local Sanuki tradition continues to read Tamura Shrine and Ichinomiya-ji as a single sacred zone whose tutelary deity protects the Takamatsu plain.

In esoteric Shingon framing, the principal Shō Kannon mediates between the cosmic Buddha and the local kami, making Ichinomiya-ji a node where the dharmadhātu manifests through the language of native Sanuki spirituality.

The precise historical sequence linking Gien, Gyōki, and Kūkai is traditional rather than documentary; the temple's earliest years are reconstructed from later engi (origin texts). The folk origin of the jigoku-no-kama is also undocumented.
