Stone Standing Statue of Acala (made by Inryu and In□)

Stone Standing Statue of Fudō Myōō (Acala) by In-ryū and In-□ at Fudō-ji Temple

Hidden among the mountains of Gunma Prefecture stands a remarkable work of devotional art that few international visitors have yet discovered. The stone standing statue of Fudō Myōō, the Immovable Wisdom King, preserved at Fudō-ji Temple bears the inscribed names of its sculptors: In-ryū (院隆) and a second master whose name has been partially worn away by the centuries. These signatures place the statue squarely within the lineage of the In-pa (院派) school, one of the three great schools of Buddhist sculpture that defined sacred imagery in medieval Japan. To stand before this stone figure is to encounter a fierce and compassionate guardian carved by hands trained in a tradition stretching back to the eleventh-century master Jōchō.

Understanding Fudō Myōō: The Immovable Wisdom King

Fudō Myōō, known in Sanskrit as Acala or Acalanātha, occupies a central place in Japanese Esoteric Buddhism. The deity is regarded as a manifestation of Mahāvairocana (Dainichi Nyorai), the cosmic Buddha, and embodies the unwavering resolve to lead all sentient beings toward enlightenment, no matter how stubbornly they may resist. His fierce countenance is not anger but compassion in its most determined form.

The iconography of Fudō Myōō is remarkably consistent and instantly recognizable. He stands with his right hand gripping a sword that severs the bonds of ignorance and delusion, while his left hand holds a rope (kensaku) used to draw wayward souls back to the path of awakening. His back is wreathed in a halo of flames, said to incinerate the defilements of the human mind. His face bears a fierce expression, often with one eye narrowed and fangs protruding from the corners of the mouth, while a single braid of hair falls over his left shoulder, signaling his role as a humble servant of the Dharma.

The In-pa School and Its Place in Japanese Sculpture

From the late Heian period through the Kamakura and Nanbokuchō eras, three sculptural lineages dominated Buddhist image-making in Japan: the In-pa (院派), the En-pa (円派), and the Kei-pa (慶派). The In-pa school traced its origins to In-shō, a successor of the celebrated Jōchō, and produced generations of master sculptors whose names began with the character "In" (院). Figures such as In-son, In-han, In-kei, In-kichi, and others worked extensively for the imperial court and aristocratic temples in Kyoto and Nara.

Most works produced by the In-pa school were carved in cypress wood, the standard material for the great Buddhist statues of medieval Japan. Stone statues bearing In-school signatures are therefore exceptionally rare and historically valuable, providing scholars with insight into how these sculptors adapted their refined techniques to a far more demanding medium.

Why Stone Was a Demanding Medium

Working in stone required entirely different tools, timing, and aesthetic judgments than working in wood. Once a chisel struck the stone, the cut could not be undone. The choice of material — usually a fine-grained sandstone or tuff in the eastern provinces — and the location of the carving site placed real constraints on the artist. To produce a refined Fudō Myōō in stone, complete with the deity's subtle facial expression and flowing drapery, required exceptional skill. The signatures of In-ryū and his collaborator on this very stone bear quiet testimony to that achievement.

Why This Statue Was Designated a Cultural Property

The statue's designation as a cultural property reflects a convergence of historical, artistic, and devotional factors. First, the inscribed signatures of two named In-pa sculptors anchor the work to an identifiable artistic lineage, allowing scholars to trace stylistic continuities and place the piece within a documented tradition. Inscribed Buddhist statues from the medieval period are uncommon, and those bearing the names of two collaborating masters are rarer still.

Second, the choice of stone as the medium sets this work apart from the wooden statues that dominate the surviving corpus of Japanese Buddhist sculpture. The piece thus serves as a precious example of how In-school sensibilities translated into a more permanent material, offering a window into regional patronage in eastern Japan during a period when major sculptural commissions were typically routed through Kyoto and Nara workshops.

Third, the work has remained in the temple where it has long been venerated, preserving the original devotional context — not as a museum piece, but as a living object of faith. This continuity of religious use, combined with its art-historical significance, justifies its protection as a cultural treasure.

Highlights for Visitors

The Sculptural Composition

Visitors who have the opportunity to view the statue are often struck first by its presence. The figure stands upright in the conventional posture of Fudō Myōō, with the sword and rope held in the prescribed positions. Despite the rigid medium, the sculptors achieved a remarkable sense of life in the contours of the body, the carving of the robe folds, and the modeling of the face.

The Inscription and Signatures

The inscription naming the sculptors is itself a focal point of interest. While the second character of one name has been lost to time, the legible portion reading "In-ryū" (院隆) confirms the work's lineage. Devotees and visitors alike can pause to consider the human story behind the carving — two masters working together, their names committed to stone in the hope that the merit of the act would endure.

The Setting

The temple grounds where the statue is enshrined offer the kind of quiet, contemplative atmosphere that has long characterized rural Japanese temples. Old trees shade the precincts, and the sounds of the surrounding mountains carry on the air. The journey to the temple itself is part of the experience.

Visiting Fudō-ji and the Surrounding Area

Fudō-ji is located in Gunma Prefecture, an area of northern Kantō richly endowed with cultural and natural attractions. Travelers who make the journey to view the temple can extend their visit to take in some of the region's other treasures. The historic town of Annaka offers preserved post-station architecture from the old Nakasendō highway, while the mountainous areas of Nanmoku, Shimonita, and the foothills of Mount Myōgi provide spectacular hiking and seasonal scenery — cherry blossoms in spring, fresh greens in summer, vivid foliage in autumn, and snow-covered peaks in winter.

Onsen towns such as Isobe, Iso, Kusatsu, and Ikaho lie within easy reach for those wishing to combine cultural sightseeing with the timeless pleasure of Japan's hot springs. Local cuisine, including konjac specialties and mountain vegetables, rounds out the experience.

Practical Considerations

Because this stone Fudō Myōō statue is a designated cultural property and a sacred object of worship, viewing arrangements may be limited. Travelers are strongly encouraged to contact the temple in advance to confirm whether viewing is possible on the date of their planned visit, and to observe any dress, photography, and conduct guidelines requested by the temple. Approaching the visit with patience and respect will be deeply appreciated by the temple community, who are the guardians of this remarkable work.
