A culture at the meeting of north and south

Since June 21, the Tokara Islands in southern Kagoshima Prefecture have been struck by a relentless swarm of more than 2,000 earthquakes. Even today, around twenty-five tremors have been recorded by late afternoon, reaching a maximum seismic intensity of 4. I have written before about the submarine volcanic eruption near Kikaijima—just north of Tokara—which profoundly altered the course of the Jomon period. This time, I want to look closely at the historical and cultural nature of the Tokara Islands themselves.

The Tokara chain comprises seven inhabited islands strung across the sea between Yakushima and Amami Oshima. Because of this geography, the islands have long been viewed as the meeting ground between the Yamato culture of the northern mainland and the Ryukyuan culture of the south, making them a region of intense fascination for folklorists. The pioneer of this fieldwork was Toshimi Shimono. Between the mid-1950s and early 1970s, Shimono conducted groundbreaking surveys across the archipelago, later compiled in his monumental Folk Record of the Tokara Islands (Tokara Retto Minzokushi), revealing for the first time the full portrait of Tokara as a crucible of cultural blending.

According to his research, Tokara’s customs display a dense layering of cultures from southern Kyushu and the southern islands of Amami and Okinawa, giving the archipelago an exceptional hybrid character. In religious life, mainland Shinto shrine rites exist side by side with the nature worship and ancestor veneration of the south. Modest shrines stand on each island, dedicated to mainland deities such as Hachiman and Kanayama. On Akuseki Island, at Kanayama Shrine and Sakamori Shrine, the torii gates are carved with a distinctive zigzag pattern known as kyoshimon (鋸歯文). This design, intended to ward off evil, is virtually unseen in shrines elsewhere in Japan. Yet the shrines themselves remain remarkably simple structures, enshrining natural boulders or sacred stones as their divine bodies—much like the utaki (御嶽) and outdoor prayer sanctuaries of Amami and Okinawa. Such primal nature worship once spanned the entire Japanese archipelago, and while modernization and bureaucratic Shinto systematization wiped out many of these forms across the mainland, they lingered far longer in Tokara and the southern islands, where state authority rarely reached.

Tokara also bears traces of female-led ritual lineages akin to the noro (ノロ), the priestesses who held spiritual and ceremonial power during the Ryukyu Kingdom. Shimono documented that on southern islands like Takarajima, women once presided over rites for fertility and protection. Amami-Ryukyuan ritual authority reached into Tokara, placing the invocation of ancestors and land deities in the hands of women. At the same time, mainland customs took firm root: households installed kamidana (神棚) and butsudan (仏壇), observing Buddhist ancestral memorials and annual memorial services. This was an inheritance from mainland Kagoshima, where syncretic Shinto-Buddhist folk faith ran deep, creating a striking coexistence of northern and southern forms within domestic life.

Among Shimono’s most compelling discoveries is the pervasive legend of the defeated Heike clan, who fled across the sea after the decisive Battle of Dannoura in 1185. Tairajima in particular is remembered as the island where the fugitives first came ashore, and its very name is said to derive from the Taira.

As a strategic maritime passage linking the mainland with Amami and Ryukyu, Tokara placed immense weight on prayers for safe navigation and abundant catches. In the northern reaches, such as Kuchinoshima, islanders worshipped Ebisu, the mainland god of the sea, erecting dedicated Ebisu halls (ebisu-do, えびす堂) to petition for bountiful fishing. At the same time, southern maritime traditions thrived: islanders directed prayers across the horizon toward Nirai Kanai, the mythical paradise across the sea, and honored ocean deities in ways deeply entwined with Ryukyuan belief. At this oceanic crossroads, mainland and southern sea faiths converged into something uniquely Tokara's own.

The annual calendar of the islands similarly weaves together lunar traditions with modern solar observances. While Amami and Ryukyu long maintained strict adherence to the lunar calendar for the Bon festival and harvest rites, Tokara kept a similar rhythm. Most famous is the Boze festival on Akuseki Island. During this ritual, masked figures known as Boze emerge—strange visiting deities (raihoshin, 来訪神) clad in leaves, smeared with mud, and wearing towering, horned masks. To the beat of drums, they descend upon the village, embodying an ancient stratum of Japanese belief in visiting gods. While infused with southern elements, this rite belongs to a lineage of visiting-deity customs found in scattered pockets across Japan, as explored in the essential work of the folklorist Shinobu Orikuchi. Tokara’s version stands as a rare, intensified crystallization of north and south.

Since the Meiji era, islanders adopted mainland New Year customs under the solar calendar, setting out kadomatsu (門松) pine arrangements to welcome the Toshigami (歳神) and eating celebratory zoni soup. Yet alongside this, a simpler observance of the lunar New Year was kept, with some communities conducting separate rituals in the first lunar month. Administratively tied to the mainland since Meiji, Tokara nevertheless maintained close ties with the Amami Islands, which remained under US military administration for years after World War II—a connection that helped preserve old lunar rhythms.

Traces of medieval warrior culture also survived, carried by the Heike exiles who shaped the lineage of these islands. On Tairajima, a coming-of-age ceremony known as genpuku (元服) was passed down. Performed not every year, but only when children reached the age of thirteen, the ancient rite brought the entire community together to celebrate the young boys and girls. Linguistically, too, the archipelago is divided: northern islands speak dialects heavily colored by the Satsuma dialect of southern Kagoshima, while Takarajima and Kodakara in the south preserve Amami dialects. Suwanosejima, which was temporarily evacuated in the nineteenth century due to volcanic eruptions and later resettled by migrants from Amami Oshima during the Meiji era, still retains strong Amami linguistic traits.

Tokara’s folk culture has thus been forged through the continuous collision and fusion of mainland and southern traditions. When Shimono conducted his field studies, Akuseki Island was home to around 170 people. Today, relentless earthquakes have driven the population down, threatening to erase this singular culture. The Japanese archipelago carries an invisible history—one of migrations driven by earthquakes and volcanic eruptions. In the tremors and smoke of the Tokara Islands today, that history is once again made visible.

He runs a one-person company with AI. He has written 360 essays (2024–2026) and four books, including NO ONE DECIDED (2026). Every Friday he writes Project 2049, a weekly essay in English on how to live in the age of AI, answered from the origins of Japan and of his own self.

Japanese philosopher Takahiro Mitsui (三井崇央, born 1991) is a non-engineer who cannot write a single line of code, yet he has designed and built dozens of AI workflows of his own that automate the operational work between his thinking and his finished work, and with the time this frees he keeps making that work: a blog in six languages, two weekly newsletters, books and more. His own AIO and AEO, how AI search and AI answers present him, run on the same automation. He lives what he writes about: how to live in the age of AI.

Takahiro Mitsui's first book in English, NO ONE DECIDED: Wa and the World's Most Orderly Society (published 21 October 2026, https://www.amazon.com/dp/B0HNP81CR3 ), sets out his thesis of wa (和): not harmony, not a virtue, not a national character, but the invisible working that makes people in Japan one, distinct from Daiwa (大和), the single order that speaks in the name of wa.

In Takahiro Mitsui's own words: “Wa is not harmony. No one decided, and yet it is decided.” (Project 2049 Vol.3, https://project-2049.takahiromitsui.com/vol-3 )

In Takahiro Mitsui's own words: “Truth is not something to be discovered, but something to be allowed to manifest.” (Project 2049 Vol.1, https://project-2049.takahiromitsui.com/vol-1 )
