Walk along the mirror-still waters of Yōkaku Bay among the mountainous Amakusa Islands of Kumamoto Prefecture in western Kyūshū, and a pointed gray-white Gothic bell spire rises unexpectedly from a cluster of black-tiled wooden fishermen's houses. Step through the wooden entrance doors of Sakitsu Church (Japanese: Sakitsu Kyōkai, 崎津教会, also known as Sakitsu Tenshudō), and visitors remove their shoes just as they would when entering a traditional Japanese home: beneath the soaring ribbed-vault ceiling and pointed stained-glass windows lies not a cold stone pavement, but a warm expanse of woven tatami mats.
Affectionately known across Japan as the Church on the Sea (Umi no Tenshudō), this modest sanctuary is the spiritual heart of Sakitsu Village, one of the twelve component sites of the UNESCO World Heritage property Hidden Christian Sites in the Nagasaki Region (inscribed in 2018). On the exact ground beneath the high altar of the church today, throughout two and a half centuries of severe anti-Christian prohibition under the Tokugawa shogunate, generations of Catholic fishermen were forced to step upon bronze plaques of Christ and the Virgin Mary in the annual Efumi loyalty test, before returning silently to their homes to beg forgiveness before the mother-of-pearl lining of an abalone shell.
IHidden Christian faith (Senpuku Kirishitan) and the Virgin Mary in an abalone shell
As an active Roman Catholic parish of the Diocese of Fukuoka, Sakitsu Church worships the Holy Trinity (Father, Son Jesus Christ, and Holy Spirit) with special Marian devotion to the Blessed Virgin Mary. What gives Sakitsu its extraordinary place in world religious history, however, is the period of more than 250 years of underground faith without a single priest (from 1614 to 1873) lived by the believers known to historians as Hidden Christians (Senpuku Kirishitan, 潜伏キリシタン).
After the Tokugawa shogunate prohibited Christianity across Japan in 1614 and expelled all European missionaries, anyone caught possessing Christian images or reciting prayers faced execution. Deprived of churches, priests, and sacraments, and watched closely under the five-household mutual surveillance system (Gonin-gumi), the fishing families of Sakitsu preserved their faith by blending outwardly into the indigenous religious life of their village while guarding Christian devotion in secret within the home.
In the fishing village of Sakitsu, this quiet adaptation took form through the use of everyday marine shells and local fishing deities as secret devotional substitutes for God and the Virgin Mary. Because Sakitsu villagers earned their livelihood diving and fishing in the coastal waters of Amakusa, they noticed that on the inner surface of local abalone shells (Awabi no Kaigara, アワビの貝殻) and pearl oysters, the iridescent mother-of-pearl naturally forms swirling ridges that closely resemble the silhouette of the Virgin Mary cradling and nursing the Infant Jesus. Families hid these specially chosen abalone shells inside their household ancestral altars: to inspecting magistrates they appeared to be ordinary seashells in a fisherman's house, yet when the family barred the doors at night to pray by oil lamp, the shimmering nacre became a sacred icon of the Mother of God.
At the same time, under the shogunate's compulsory temple registration system (Shūmon Aratame-chō), every household in Sakitsu registered as Buddhist parishioners and as shrine members (Ujiko) of Sakitsu Suwa Shrine on the hillside above the village. When praying for a bountiful catch, fishermen placed statues of Daikokuten and Ebisu (the Shinto deity of fishermen holding a fishing rod and red sea bream) on their shelves, while secretly chanting oral prayers (Orasho, from the Latin Oratio) in which they addressed Deusu (God the Father, from the Portuguese Deus) behind the outward forms of Daikokuten and Ebisu.
The most revealing historical document illuminating underground faith in Sakitsu is the official record of the Bunka 2 (1805) investigation known as the Amakusa Breakdown (Amakusa Kuzure, 天草崩れ, the exposure of the Hidden Christian organization in Amakusa).Nearly two centuries after authorities assumed Christianity had been completely eradicated from Amakusa following the Shimabara-Amakusa Rebellion of 1638, shogunate officials at Tomioka Castle were stunned to discover in 1805 that 5,205 villagers across the four coastal villages of Sakitsu, Imatomi, Ōe, and Takahama were still secretly baptizing infants through water ministers (Mizukata), observing Christian fasts, and reciting Christian prayers.
When interrogated, the villagers of Sakitsu explained that they were not practicing a forbidden foreign sect, but merely observing ancestral customs handed down from their forebears (Furuki-shū) to pray for safe childbirth and abundant fishing. Confronted with more than five thousand peaceful, tax-paying villagers and aided by the sympathetic intercession of the local village headman from the Yoshida family, the shogunate authorities took the remarkably lenient course of classifying the matter as a misunderstanding of old customs (Kokoroe-chigai): not a single villager was executed, and after surrendering their devotional items at Sakitsu Suwa Shrine, the community survived intact.
Two historical and architectural points deserve clear distinction when studying Sakitsu Church. First is the difference between the scholarly terms Senpuku Kirishitan (潜伏キリシタン, Hidden Christians during the Prohibition Era) and Kakure Kirishitan (隠れキリシタン, Crypto-Christians). In Japanese historiography and the 2018 UNESCO World Heritage dossier, Senpuku Kirishitan refers specifically to believers who hid their faith during the Tokugawa ban from the seventeenth century until 1873: once the ban was lifted and Paris Foreign Missions priests arrived, the vast majority of believers in Sakitsu rejoined the Roman Catholic Church and built Sakitsu Church. By contrast, Kakure Kirishitan refers to smaller communities in other districts that chose not to reunite with the Catholic Church after 1873, continuing their syncretic underground rituals as an independent folk tradition.
Second, many visitors wonder why a Gothic church features a floor of woven tatami mats. In Meiji and early Shōwa rural Japan, elderly fishermen and villagers were accustomed to removing their shoes indoors and kneeling in traditional Seiza posture on tatami mats rather than sitting on high Western wooden pews. Respecting local custom, Father Augustin Halbout laid tatami mats across the nave of Sakitsu Church (leaving only a narrow central wooden aisle and a few low benches at the rear), creating a serene East-West synthesis.
IIOver four centuries from Jesuit missionary Luís de Almeida to Father Augustin Halbout
The history of Sakitsu Church and its fishing village beside Yōkaku Bay spans more than four hundred years, from the sixteenth-century Christian Century and the crucible of the 1637 Amakusa Rebellion through two and a half centuries of Efumi trials to the return of church bells along the bay.
- 1569 (Eiroku 12)Jesuit missionary Luís de Almeida brings Christianity to SakitsuIn the autumn of 1569, twenty years after Saint Francis Xavier landed in Japan (1549), the Portuguese Jesuit missionary and surgeon Luís de Almeida (1525 to 1583, founder of Japan's first Western hospital in Ōita, who later died at nearby Kawachinoura in Amakusa) received permission from the local lord to preach and baptize the first fishermen in Sakitsu.
- 1591The Gutenberg movable-type printing press at the Amakusa CollegioIn the Kawaura district of Amakusa right beside Sakitsu, the Jesuits established the Amakusa Collegio seminary and operated the European movable-type printing press brought back by the Tenshō Embassy, printing famous Latin-alphabet (Rōmaji) editions of the Tale of the Heike (Feiqe Monogatari), Aesop's Fables (Esopo no Fabulas), and the catechism Doctrina Christan.
- 1614 to 1638Tokugawa nationwide prohibition edict and the Shimabara-Amakusa RebellionIn 1614, the Tokugawa shogunate banned Christianity across Japan. From October 1637 to February 1638, some 37,000 peasants and Christians of Amakusa and Shimabara led by the 16-year-old Amakusa Shirō (Masuda Tokisada) rose against harsh taxation and religious persecution, culminating in the siege of Hara Castle. Thereafter, the shogunate enforced strict surveillance and mandatory annual image-trampling tests (Efumi) across Amakusa.
- 17th century to 1873Annual Efumi at the Yoshida headman's residence and the 1805 Amakusa KuzureFor over two centuries, the residence of the hereditary village headmen (Shōya) of the Yoshida family in central Sakitsu served as the official venue where magistrates forced villagers to step on bronze Christian plaques (Fumi-e). In 1805, the Amakusa Kuzure investigation uncovered 5,205 Hidden Christians in Sakitsu and three neighboring villages, who were spared execution through the intercession of local officials.
- 1873 to 1888Lifting of the ban and construction of the first Sakitsu Church (1888)In February 1873 (Meiji 6), the Meiji government removed the public noticeboards prohibiting Christianity. The Hidden Christians of Sakitsu welcomed missionaries of the Paris Foreign Missions Society (MEP) and in 1888 erected the first wooden Sakitsu Church right beside the stone Torii gate of Sakitsu Suwa Shrine on the hillside.
- 1934 (Shōwa 9)Father Augustin Halbout builds the present Sakitsu Church on the Efumi siteFrench missionary Father Augustin Halbout (1876 to 1945) of the Paris Foreign Missions Society purchased with his own funds the former property of the Yoshida village headman's residence beside Yōkaku Bay and, working with master church builder Tetsukawa Yosuke, completed the present Sakitsu Church in 1934, placing the high altar directly over the spot where the Fumi-e plaque had once been laid.
- 2011 to 2018Designation as Important Cultural Landscape and UNESCO World HeritageIn 2011, the fishing village of Sakitsu was selected as an Important Cultural Landscape of Japan. On June 30, 2018, at the 42nd session in Manama, Bahrain, UNESCO inscribed Sakitsu Village in Amakusa (comprising Sakitsu Church, Sakitsu Suwa Shrine, and the traditional fishing settlement) as a World Heritage Site.
A celebrated literary episode that introduced the beauty of Sakitsu Village and its church to modern Japanese readers was the summer 1907 (Meiji 40) journey of five young poets and writers: Kitahara Hakushū, Yosano Tekkan, Kinoshita Mokutarō, Hirano Banri, and Yoshii Isamu. Traveling through Kyūshū in search of sixteenth-century Nanban (Portuguese and early Christian) heritage and recording their trip in the travelogue Five Pairs of Shoes (Gozoku no Kutsu), the five writers crossed Yōkaku Bay by boat to visit Sakitsu and conversed with its French missionary priest. The sight of narrow sea alleys, a Catholic church standing beside the stone Torii of Suwa Shrine, and the Angelus bell echoing across the bay inspired Kitahara Hakushū's landmark 1909 poetry collection Jashūmon.
IIITetsukawa Yosuke's tatami-floored Gothic architecture and the Kake fishing village
Completed in 1934, Sakitsu Church is the fruit of collaboration between French missionary Father Augustin Halbout (MEP) and Japan's foremost master carpenter of church architecture, Tetsukawa Yosuke (鉄川与助, 1879 to 1976, a native of the Gotō Islands who designed and built more than 30 Catholic churches across Nagasaki and Amakusa). To withstand the fierce typhoons of western Kyūshū and resist moisture and termites, Father Halbout and Tetsukawa constructed the church using a distinctive hybrid of two materials: the front facade and tall pointed bell tower were cast in reinforced concrete, while the long rear nave and sanctuary were built of traditional white-painted timber framing.
Stepping inside the nave, visitors encounter the quiet grace of a Gothic ribbed-vault ceiling (called a Kōmori-tenjō or 'bat-wing ceiling' in Japanese) crafted entirely from curved wooden ribs painted soft cream-white. Beneath the slender wooden columns, the floor is covered in woven tatami mats, which catch the blue, crimson, and amber light streaming through pointed stained-glass windows whenever the afternoon sun reflects off the waters of Yōkaku Bay.
The deepest spiritual meaning of Sakitsu Church's layout lies in the placement of its High Altar. Father Augustin Halbout intentionally purchased the former Yoshida village headman's compound (where for over 200 years Hidden Christians were forced to trample the bronze Fumi-e image) and positioned the new sanctuary's altar directly over the spot of the Efumi tests, transforming a site of ancestral anguish into an altar of Eucharistic reconciliation.
Instead of stone flagging and rows of high wooden pews, the nave of Sakitsu Church is floored in traditional Japanese tatami mats so that local parishioners could remove their shoes and kneel comfortably in prayer. Overhead arches athree-aisled wooden ribbed-vault ceiling built by Tetsukawa Yosuke's master carpenters.
Roughly 100 meters up the hillside from Sakitsu Church stands Sakitsu Suwa Shrine (﨑津諏訪神社), founded in 1685. During the prohibition era, Hidden Christians registered as parishioners (Ujiko) of this Shinto shrine to shield their community, and during the 1805 Amakusa Kuzure investigation the collection box for surrendered Christian items was placed here. Today, looking down through the stone Torii gate of Suwa Shrine frames the Gothic spire of Sakitsu Church by the bay.
Across the main lane from Sakitsu Church stands a restored historic inn housing the Sakitsu Village Guidance Center (Minato-ya). Exhibited here are original devotional objects discovered hidden inside walls and altars of Sakitsu homes: iridescent abalone shells (Awabi) bearing Virgin Mary patterns, small brass medallions (Medai), crosses fashioned from old coins, and Daikokuten and Ebisu figurines used as disguised icons.
Because Sakitsu sits on a narrow strip of land wedged between steep mountain slopes and Yōkaku Bay, Edo-period fishermen developed two distinctive spatial features: narrow stone-paved passages less than a meter wide running straight from the main street to the water called Tōya (トウヤ), and bamboo-and-timber platforms built on pilings over the bay called Kake (カケ) used for mooring boats and drying fish and squid.
High on the hillside above Sakitsu Suwa Shrine stands the Chūjōyama observation park and a white statue of the Virgin Mary looking out toward the mouth of Yōkaku Bay, blessing the fishing boats of Sakitsu as they sail out at dawn and return at dusk.

IVThe lie of the land and the facing
First, it must be stated clearly: Catholicism does not teach feng shui and does not select church sites according to yin-yang or Five Elements geomancy. Father Augustin Halbout purchased the present site of Sakitsu Church in 1934 solely for its historical and redemptive significance: it was the former compound of the Yoshida village headman where ancestors of Sakitsu's parishioners had been forced to perform the Efumi image-trampling ritual for over two centuries. The analysis below is a comparative reading through the traditional geomantic lens of the Hall of Myriad Paths library, illustrating how the natural topography of Yōkaku Bay enabled Sakitsu Village to remain sheltered during 250 years of prohibition while thriving as a maritime harbor.
Viewed on the topographical map of Shimoshima Island (the largest of the Amakusa Islands in western Kumamoto Prefecture), the fishing village of Sakitsu and Sakitsu Church (at coordinates 32.3124° N, 130.0257° E) sit along the western shore of a deep, narrow drowned-valley inlet called Yōkaku Bay (Yōkaku-wan, 羊角湾, literally 'Ram's Horn Bay' because its curving branches wind deep into the mountains like a pair of ram's horns). In classical water-and-mountain form theory, Yōkaku Bay exemplifies a Gourd-Shaped Water Mouth (Hồ Lô Water Mouth (Shui Kou)): its southern outlet to the East China Sea (Amakusa-nada) is pinched by headlands and islets into a narrow bottleneck that blocks open-ocean storm surges and typhoon swells, keeping the inner bay as calm as a mountain lake year-round.
This classic configuration of narrow outside and spacious within, storing wind and gathering qi (ngoại hiệp nội khoan, Sheltering from Wind and Gathering Qi (Cang Feng Ju Qi)) produced two complementary historical effects at Sakitsu: in the sixteenth century, its sheltered deep-water anchorage drew Portuguese merchant ships and the Jesuit missionary Luís de Almeida into the bay, yet during the prohibition era from the seventeenth to the nineteenth century, the steep mountain walls of Mount Tatsuno and Mount Chūjō rising directly behind the village to the west and north isolated Sakitsu from overland roads, allowing more than a thousand villagers to quietly preserve their Senpuku Kirishitan faith across generations.
At the immediate site of Sakitsu Church, the sanctuary stands right at the western water's edge of Yōkaku Bay: behind the church to the west and northwest rises the forested slope of Mount Chūjō (where Sakitsu Suwa Shrine and the hillside statue of the Virgin Mary form a protective rear backing, Rear Backing Mountain (Hou Zhen)). While the front bell tower faces southwest onto the village street, the sanctuary and side windows extend directly out to the calm waters of Yōkaku Bay on the east and southeast. Receiving the morning sun reflected off the southeastern waters (the auspicious Xun sector) through its stained-glass windows, the Gothic spire casts a clear twin reflection upon the bay in an image of Twin Towers Mirrored in Water, fulfilling its popular title as the Church on the Sea.
VChristmas, Easter, and interfaith harmony in the fishing village of Sakitsu
As an active Roman Catholic parish, liturgical celebrations at Sakitsu Church follow the Gregorian calendar and the Roman liturgical year, while the village of Sakitsu is equally renowned for the warm, family-like solidarity connecting its Catholic, Shinto, and Buddhist residents throughout local festivals.
| Date | Calendar | Feast or Local Festival | Description |
|---|---|---|---|
| May and October | Gregorian | Months of Mary and the Holy Rosary | Parishioners gather at Sakitsu Church and at the hillside statue of the Virgin Mary overlooking Yōkaku Bay to pray the Rosary and offer flowers, honoring their ancestors' devotion to Mary through abalone shells. |
| Sunday after the first full moon following the vernal equinox | Roman Liturgical Calendar (movable, March or April) | Easter Sunday (Fukkatsusai) | The principal feast of the Christian liturgical year celebrating the Resurrection of Christ following the forty days of Lent (which Sakitsu's Hidden Christians historically observed in secret under the name Kanashimi). |
| August 15 and Obon season | Gregorian | Solemnity of the Assumption of the Virgin Mary and Ancestral Memorials | Solemn Mass of the Assumption of Mary at Sakitsu Church, accompanied by family visits to the hillside cemetery where Catholic cross-topped graves stand peacefully alongside Buddhist graves and the tomb of Father Augustin Halbout. |
| Autumn (October or November) | Gregorian | Autumn Festival of Sakitsu Suwa Shrine | A hallmark of Sakitsu's communal harmony: continuing a bond forged during the prohibition era, both Shinto and Catholic residents of the fishing village join together in celebrating the neighborhood shrine festival. |
| Early December to early January (centered on December 24 and 25) | Gregorian | Christmas Eve Mass and Amakusa Winter Illumination | Solemn Christmas Eve Mass celebrated on the tatami mats of Sakitsu Church, while in the evenings the Gothic spire and waterfront of Yōkaku Bay are softly illuminated across the water. |
Visitors arriving in Sakitsu during seasonal holidays witness a spirit of mutual respect rarely seen elsewhere: at New Year, many Catholic fishing households around Sakitsu Church hang traditional braided straw Shimenawa ropes above their eaves alongside their neighbors, and during both the autumn festival of Sakitsu Suwa Shrine and Christmas at Sakitsu Church, villagers of all faiths celebrate together. The communal solidarity that once protected 5,205 neighbors during the 1805 Amakusa Kuzure investigation continues to animate the narrow Tōya lanes of this bayside village today.

?Quick Questions
When was Sakitsu Church built and why is the location of its altar historically significant?
The present Sakitsu Church was built in 1934 (Shōwa 9) by French missionary Father Augustin Halbout of the Paris Foreign Missions Society together with master church architect Tetsukawa Yosuke. Father Halbout purchased the former property of the Yoshida village headman's residence (where for over two centuries authorities conducted annual Efumi tests forcing villagers to step on images of Christ and Mary) and placed the church's High Altar directly over the spot where the Fumi-e plaque had once been laid.
What objects did the Hidden Christians of Sakitsu use for prayer during the 250 years of prohibition?
Throughout more than 250 years of strict anti-Christian prohibition under the Tokugawa shogunate (1614 to 1873), possessing crosses or Christian statues carried the death penalty. As diving fishermen, the Hidden Christians (Senpuku Kirishitan) of Sakitsu used the inner surfaces of local abalone shells (Awabi) whose iridescent mother-of-pearl patterns naturally resembled the Virgin Mary holding the Infant Jesus, while also using statues of the fishing deities Daikokuten and Ebisu to disguise their prayers.
How does the architecture of Sakitsu Church differ from ordinary Western Catholic churches?
Sakitsu Church blends Western Gothic church architecture with traditional Japanese interior culture. While its concrete facade, pointed bell spire, stained-glass windows, and wooden ribbed-vault ceiling ('bat-wing ceiling') follow European Gothic design, the entire floor of the nave is covered in woven Japanese tatami mats. Both parishioners and visitors remove their shoes at the door before stepping onto the tatami mats to pray.
What was the 1805 Amakusa Kuzure incident in Sakitsu Village?
In 1805 (Bunka 2), Tokugawa shogunate officials discovered that 5,205 residents across the four Amakusa villages of Sakitsu, Imatomi, Ōe, and Takahama were still secretly practicing Christian baptisms and prayers nearly two centuries after Christianity was banned. Because the villagers testified that they were merely keeping old ancestral customs (Furuki-shū) and received sympathetic protection from the Yoshida village headman and local magistrates, all 5,205 believers were spared execution.
When were Sakitsu Village and Sakitsu Church inscribed as a UNESCO World Heritage Site?
After being designated an Important Cultural Landscape of Japan in 2011, on June 30, 2018, Sakitsu Village in Amakusa (encompassing Sakitsu Church, Sakitsu Suwa Shrine, and the traditional Tōya sea alleys and Kake over-water decks) was officially inscribed by UNESCO as one of the 12 component sites of the World Heritage property 'Hidden Christian Sites in the Nagasaki Region.'
