Hi, this is Ai. If you spend much time reading English-language travel writing about Mie Prefecture, you will eventually run into a sentence that says, more or less, “Toba is the home of the ama, the women divers, who have been recognized by UNESCO.” I have seen versions of this sentence in print, on websites, and even on tour-bus narration scripts. The sentence is well-meaning. It is also not quite right, and the way it is wrong is worth understanding, because the actual heritage status of the ama tradition is a more interesting story than the simplified version suggests.
So I want to take this article slowly. Toba sits a short train ride east of Ise. The coast there is one of the longest continuously inhabited diving-culture regions in the world, and the tradition is changing. There is a real heritage designation — but it is a Japanese one, granted in 2017. There is a real conversation about UNESCO recognition — but it is still ongoing, and it involves a sister tradition across the sea in Korea that received UNESCO inscription back in 2016. The distinction matters for anyone trying to write about, photograph, or visit the ama culture honestly.
Grandpa explained this to me one evening when I came home with a brochure I had picked up at a small information desk near Toba Station. The brochure used the phrase “world heritage” loosely, and I had been about to write a draft based on it. He read the brochure carefully and put it down. “The wording is doing a lot of work it shouldn’t be doing,” he said. So this is the article I wrote instead.
What the ama tradition actually is, in strict terms
The Japanese word ama (海女 for women, 海士 for men) refers to divers who go down into the sea without breathing apparatus and harvest abalone, turban shells, sea urchin, seaweed, and other shellfish from the seabed. There are coastal districts in Mie, Ishikawa, Chiba, and elsewhere where the tradition continues, but the densest cluster has long been the Toba-Shima coastline, where small fishing settlements have been organized around ama work for centuries.
How long? Written records in the Engishiki, the tenth-century compilation of administrative rules, describe ama-collected abalone being offered to Ise Jingu as part of the regular shinsen — the sacred food offerings made to the deities. The continuous documentary connection between the Toba-Shima ama and the offerings of Jingu is, in fact, one of the reasons the tradition is treated as part of a single regional cultural complex rather than as an isolated occupational practice. Archaeological evidence of shell-midden communities along the coast goes back much further, but the administrative connection is what historians of religion tend to anchor on.
What makes Toba particularly significant within this picture is that the local fishing cooperatives have, for generations, deliberately not modernized the diving technique. Scuba gear became available in the twentieth century. It is not used. Hard-hat surface-supplied diving is also not used. The choice is intentional: the harvest stays within physical limits the divers can sustain by breath alone, and the resource — particularly abalone, which is slow to regenerate — is protected by the same constraint. This is, in a real sense, the technological self-restraint that makes the tradition something more durable than a costume.
Japan Heritage, granted in 2017
In 2017 the Japanese Agency for Cultural Affairs (Bunka-cho) granted “Japan Heritage” status to a regional story titled, in translation, “The Town Where You Can Meet the Ama: Toba and Shima — Women Who Live by Breath-Hold Fishing.” This is a domestic Japanese designation. It is awarded by a Japanese national government agency. The list it sits on is a Japanese list.
The Japan Heritage program, launched in 2015, is structured differently from most cultural-property designations a foreign visitor might be familiar with. Rather than registering individual buildings or objects, it recognizes stories — clusters of sites, practices, and traditions that together tell a coherent regional history. The Toba-Shima ama designation bundles the diving practice itself, the small huts (amagoya) where divers warm themselves between dives, the local shrines where divers pray before going out to the rocks, the seafood culture (grilled abalone, Ise-ebi lobster, sea urchin) that the harvest sustains, and the protective symbols doman and seman — a five-pointed star and a nine-line grid — that ama have traditionally embroidered onto their diving clothing as protection against the sea.
It is a meaningful and well-designed designation. It is also, importantly, not a UNESCO designation. Japan Heritage and UNESCO Intangible Cultural Heritage operate at different scales, are granted by different bodies, and are conferred for different reasons. Writing about Toba’s ama in English, the precise word matters.
The UNESCO question, and the Korean sister tradition
Here is where the picture becomes more complex, and more interesting.
The Korean coastal tradition most comparable to the Japanese ama is the haenyeo of Jeju Island. The haenyeo are also breath-hold women divers, also harvest abalone and other shellfish from the seabed, and are also organized around small cooperative communities along a coastline. The resemblance is not coincidental — the two traditions appear to share deep historical roots, and there has been documented exchange between Korean and Japanese diving communities over the centuries.
In 2016, UNESCO inscribed the Culture of Jeju Haenyeo (Women Divers) on the Representative List of the Intangible Cultural Heritage of Humanity. This is the actual UNESCO list. The Korean tradition is on it. The Japanese ama tradition, as of this writing, is not.
There has been ongoing discussion in Mie Prefecture, in Japanese folklore studies, and among the coastal communities themselves about whether the Japanese ama tradition should pursue UNESCO inscription as well — possibly on its own, possibly as a joint Japan-Korea cross-border listing of breath-hold women’s diving traditions. The conversation is real, the documentation work is real, and the academic cooperation between researchers on both sides of the Sea of Japan is real. But the inscription itself has not yet happened for the Japanese side.
So when an English-language source describes Toba’s ama as “UNESCO-recognized,” what is almost certainly being remembered is either the 2017 Japan Heritage designation (which is not UNESCO) or the 2016 Korean haenyeo inscription (which is UNESCO, but is the sister tradition, not the Japanese one). Both confusions are easy to make. Neither is malicious. But for a visitor trying to understand the heritage status of what they are looking at, the difference is worth holding clearly.
What the distinction means for a visitor
The honest summary is this. The Toba ama tradition holds Japanese national heritage status. The international recognition that the Korean sister tradition received in 2016 has prompted ongoing work toward similar UNESCO recognition for the Japanese tradition, but as of 2026 that work is not complete.
For a visitor, the practical effect of this distinction is small. The diving still happens. The ama huts still operate in some districts. The Toba Sea-Folk Museum, which I will say more about in the next section, still holds the most thorough public collection of ama equipment, history, and oral testimony anywhere in Japan. None of these are diminished by the absence of a UNESCO plaque.
What the distinction does change is the kind of attention a visitor brings. UNESCO Intangible Cultural Heritage frames a tradition as a shared global responsibility — something humanity has collectively decided to protect. Japan Heritage frames it as a national story, told by Japan to its own visitors and to itself. Both are legitimate frames. They simply ask the visitor to listen at slightly different distances. Knowing which frame you are inside while you are inside it changes what you actually hear.
Where to actually go: the Toba Sea-Folk Museum
If you are coming to Toba with even a passing interest in the ama tradition, the single place I will recommend without hesitation is the Toba Sea-Folk Museum (Toba Shiritsu Umi no Hakubutsukan). According to the museum’s published exhibition descriptions, the collection includes the isogane — the iron tool used to detach abalone from rock — along with diving goggles, weight belts, and reproductions of the amagoya huts where divers warm themselves between dives around an open fire. There is also extensive documentation of the doman and seman protective symbols that ama have traditionally marked onto their diving clothing.
The museum is set away from the main tourist concentration around Toba Station, which is part of why it works. It is a research-led institution, not a souvenir stop, and the exhibition design assumes you are there to learn rather than to be entertained. Allow at least two hours. If you read Japanese, plan more. The English signage is partial but the visual material communicates clearly even where the text does not.
What this museum offers that the in-village ama-hut experiences do not is context. Several ama districts now host small “ama hut” lunch experiences where visitors can sit with active or retired divers, eat grilled shellfish, and ask questions. These experiences are valuable and the seafood is excellent. But they are not a substitute for the historical and material context the museum provides, and the order in which a thoughtful visitor takes them matters. Grandpa phrased it like this once, and the phrasing has stayed with me: the museum is for understanding what the work is; the hut is for meeting the people who do it. If you only have time for one, choose the museum. If you have time for both, do them in that order.

A short note on Ousatsu and the Ishigami shrine
The fishing community of Ousatsu, on the south side of the Toba peninsula, is widely cited as having one of the highest concentrations of active ama in Japan. Within the precincts of Shinmei Shrine in Ousatsu sits a smaller shrine known locally as Ishigami-san, where ama have historically prayed before going to the sea. According to the shrine’s own information, Ishigami-san is locally associated with the granting of one wish per visitor.
I am keeping this section short on purpose. Ousatsu has become better known internationally over the past decade, and the Ishigami-san shrine in particular sees a lot of visitors now. The community is still a working fishing village, and the people praying at the shrine on a given morning are not all tourists. If you visit, follow the standard shrine etiquette — bow at the torii, wash at the temizuya, two bows, two claps, one bow — and keep camera and voice quiet. The presence of visitors is welcomed by the shrine; the presence of crowds in a place that is still part of someone’s daily life requires care.
What Grandpa said about reading the sea
We were sitting on the engawa one evening earlier this spring, after I had come home from a research day in Toba. I had a stack of museum pamphlets and a notebook full of half-written paragraphs and a small worry that I was making the article too complicated.
Grandpa listened to my draft summary and then said something I have been turning over since. The ama tradition, he said, is not interesting because it is old. It is interesting because the people who do it have, generation after generation, made a deliberate decision about how to relate to a finite resource. They chose breath. They chose the slow harvest. They chose to leave the abalone in the sea long enough to grow back. The international heritage conversation — UNESCO, Japan Heritage, all of it — is a way for the rest of us to acknowledge that decision and try to learn from it.
That framing helped me understand why the heritage question is more than a labeling exercise. The recognition matters because the practice matters. And the practice matters because of what it teaches about restraint. Writing about Toba in any honest way, I think, has to keep that center in view.
There is a small connection here to the larger project this blog is built around. The Shikinen Sengu rebuilds the Ise Jingu shrines every twenty years not because they fall down, but because the cyclical rebuilding renews the craft traditions and the relationship between the shrines, the forests that supply the timber, and the communities that supply the offerings. The ama-supplied abalone is part of those offerings — and one of the most significant moments at which it appears is the annual Kanname-sai, which I have written about separately for visitors planning an October trip (Kanname-sai on October 17: ritual structure and visitor protocol). Both the rebuilding and the breath-hold harvest are forms of cultural self-pacing — disciplined refusals to push a system past what it can sustain. Seeing the two together helps the visit to either one make more sense.
Closing: what to do with the heritage question
If you came into this article expecting to find a simple “yes, UNESCO” or “no, not yet” answer, the honest answer is the second one with an asterisk. Toba’s ama tradition holds Japanese national heritage status from 2017. It does not currently hold UNESCO Intangible Cultural Heritage status. The Korean haenyeo, the closest sister tradition, was inscribed by UNESCO in 2016, and the conversation about a comparable inscription for the Japanese tradition is ongoing. That is the precise picture.
For a visit, three concrete suggestions.
First, give the Toba Sea-Folk Museum at least half a day. The museum is where the heritage question becomes a set of objects you can stand in front of.
Second, if you have a second day in Toba, consider an ama-hut lunch in one of the smaller villages. Local tourism information offices can recommend currently operating huts, since the list changes year to year. Eat slowly. Ask questions. Listen more than you speak.
Third, if you are coming through Ise on the way, take the same Sangu Line train I have mentioned in earlier pieces and let the coast appear gradually outside the window. Toba is not a destination you arrive at suddenly. It is a place you ease into, and the easing is part of the experience.
I will keep this blog with the ama tradition for the long arc, the same way I am keeping it with the Shikinen Sengu through 2033. If the UNESCO status changes in the years ahead, I will write a follow-up. Until then, the precise word remains Japan Heritage, and the conversation about anything beyond that remains exactly that — a conversation, worth listening to without summarizing too quickly.
