Pirikanoka: Hokkaido's Sacred Landscapes Painted in the Ainu Language
Scattered across the breadth of Hokkaido, from the northern reaches of Soya to the rugged southern cape of Erimo, lies a remarkable group of natural landscapes that share a single, evocative name: Pirikanoka. The word comes from the Ainu language, where "pirka" means "beautiful" and "noka" means "shape" or "form." Together, they denote landscapes whose extraordinary beauty has been recognized, celebrated, and revered by the Ainu people for countless generations. In 2009, Japan's national government formally designated this group of scenic places as a single Cultural Property under the country's Cultural Properties Protection Act, creating one of the most distinctive heritage listings in all of Japan—a property that spans hundreds of kilometers and embraces mountains, capes, rocky outcrops, and coastlines, all bound together by the stories, prayers, and language of the indigenous Ainu people.
The Pirikanoka designation currently encompasses ten component sites located across eleven municipalities of Hokkaido, including Nayoro, Ishikari, Hamatonbetsu, Esashi, Erimo, Engaru, Toyoura, Muroran, Obihiro, Nakasatsunai, Biratori, and Niikappu. Each site has been added in stages over the years, beginning with two mountains in 2009 and growing to include seacoasts, sacred capes, fortress-like rock formations, and revered alpine peaks. What unites them is not their geological similarity—indeed, they are remarkably varied—but the cultural significance they hold within Ainu oral tradition. Each is a place where landscape and language meet, where a mountain or a stretch of shoreline carries within its very name a story handed down through generations.
The Ainu People and Their Sacred Geography
The Ainu are the indigenous people of Hokkaido, the southern Kuril Islands, and Sakhalin. Their worldview, known as the Ainu Puri, is grounded in the belief that all things in the natural world—mountains, rivers, animals, plants, fire, and even human-made tools—possess a spirit or soul, called kamuy. Especially powerful or beautiful natural features were recognized as the dwellings of particularly important kamuy, and these places were treated with reverence, respect, and ritual.
Among such sacred places, certain mountains were called chinomi shir, meaning "mountain we worship." These were not climbed casually; they were prayed to, and they served as landmarks for hunting, navigation, and seasonal life. Other geographical features became the settings of yukar, the long oral epics that told of heroic deeds, divine beings, and the founding of the world. The Pirikanoka group brings together the most outstanding of these landscapes—places where the Ainu language, oral literature, and spiritual life are inseparable from the land itself.
Why Pirikanoka Was Designated a National Cultural Property
Hokkaido has long been recognized for the splendor of its natural scenery, but for much of the twentieth century, protection of named scenic places (meishō) under Japan's cultural heritage system tended to focus on classical Japanese gardens, famous historical viewpoints, and sites associated with literary tradition rooted in mainland Japan. Hokkaido's distinctive scenic heritage—deeply connected to Ainu culture rather than to wakan classical aesthetics—was for many decades comparatively under-protected.
The Pirikanoka designation was conceived to address this gap. By recognizing these places collectively, under their Ainu names, the government affirmed that the cultural value of these landscapes derives precisely from their entwinement with Ainu language, story, and spirituality. The designation honors not only the visual beauty of each site, but also its role within Ainu cosmology, history, and daily life. For the first time in Japan's national meishō listings, a category was created specifically to celebrate landscapes through indigenous cultural understanding.
Each component site was added to Pirikanoka individually after careful research into its physical characteristics, its place in Ainu oral tradition, and its scenic excellence. The result is a layered, evolving designation that grows as additional places are studied and recognized.
Highlights of the Ten Component Sites
Kudosan (Kutunnupuri) — Nayoro City
Visible from the streets of Nayoro in northern Hokkaido, Kudosan is a 673.6-meter mountain whose Ainu name, Kutunnupuri, means "mountain with a rocky cliff." The peak's asymmetrical ridge and the rocky pinnacle at its summit give it an instantly recognizable silhouette. For the Ainu of the Nayoro region, it was both an object of daily prayer and an essential landmark during hunting expeditions. Today the same mountain is home to the Piyashiri Ski Area and offers hiking trails that draw outdoor enthusiasts year-round.
Koganeyama (Pinnetaiorushpe) — Ishikari City
Rising in pyramidal beauty to 739.1 meters above the coastal plain of Hamamasu in Ishikari, Koganeyama bears the Ainu name Pinnetaiorushpe, often translated as "the male mountain rising in a forested plain." The mountain figures prominently in the yukar of Poiyaunpe, a young hero whose adventures form one of the great narrative cycles of Ainu oral literature. The summit affords sweeping views over the Sea of Japan.
Kamui Misaki (Kamuietu) — Hamatonbetsu and Esashi
Often called Kitami Kamui Misaki to distinguish it from other capes of the same name in Hokkaido, this dramatic headland on the Sea of Okhotsk coast was known to the Ainu as Kamuietu, "the cape of the kamuy." The cliffs, the offshore rock pillars, and the spirit-thick atmosphere of the sea here have long been considered the realm of powerful deities.
Erimo Misaki (Onneenrum) — Erimo Town
At the southern tip of the Hidaka mountain range, where the central spine of Hokkaido plunges into the Pacific Ocean, lies Cape Erimo. Its Ainu name, Onneenrum, means "the great cape." This was added to Pirikanoka in August 2010. Famous for its strong winds, churning currents, and a colony of Kuril harbor seals that lives among its offshore reefs, Erimo presents one of Japan's most wild and elemental seascapes.
Ganboiwa (Inkarushi) — Engaru Town
A sheer 78-meter rock outcrop rising abruptly from the floodplain of the Yubetsu River, Ganboiwa is known in Ainu as Inkarushi, "the place to look out from." The rock is built of hard volcanic breccia, and its resistance to erosion has left it standing as a natural watchtower. According to legend, the Ainu of the Yubetsu region took refuge here during a long battle with the Tokachi Ainu, with the river itself eventually flooding to decide the conflict. The town name "Engaru" itself derives from "Inkarushi." Inkarushi was added to Pirikanoka in February 2011, becoming the fifth designated component and the first within the Okhotsk region.
Kamui Chashi — Toyoura Town
"Chashi" is an Ainu term for a fortified site, and Kamui Chashi—"the chashi of the kamuy"—is a striking coastal feature on the Pacific coast of southern Hokkaido. The site embodies the meeting of fortification, ritual, and dramatic seascape that runs through so many Ainu sacred places.
The Outer Coast of the Etomo Peninsula — Muroran City
Designated in January 2012, this section of Pirikanoka encompasses four distinct localities along the wave-battered Pacific coast of the Etomo Peninsula in Muroran: Harukaramoi, Masuichi-hama, Chikyū-misaki (Cape Chikyū, often called the "Cape of the Earth" for its sweeping curve to the horizon), and Tokkarisho-hama. The cliffs and offshore stacks here include some of Hokkaido's most photographed coastal scenery.
Tokachi-Poroshiri-dake (Poroshiri) — Obihiro City and Nakasatsunai Village
Standing 1,846 meters tall in the northeastern Hidaka range, Tokachi-Poroshiri-dake takes its name from the Ainu words "poro" (great) and "shiri" (mountain). The Ainu of the Tokachi region revered it as a chinomi shir, a sacred peak inhabited by the kamuy. The mountain features sharp ridgelines and well-developed cirque (kar) topography near the summit—an enduring legacy of the last ice age. It was added to Pirikanoka in September 2012 as the eighth component.
Poroshiri-dake (Poroshiri) — Biratori Town and Niikappu Town
Not to be confused with the Tokachi-Poroshiri described above, this Poroshiri-dake is the highest peak of the entire Hidaka range, rising to 2,052 meters. Standing on the spine of southern Hokkaido, its alpine flora and dramatic cirques make it one of Japan's "Hyakumeizan" (100 Famous Mountains). Reaching the peak requires multiple river crossings on foot, and serious mountaineering experience is required.
Okikurmi no Chashi and Muinoka — Biratori Town
In Biratori, near the Saru River valley—long considered a heartland of Ainu culture—rise two rocky hills associated with one of the most important figures in Ainu mythology. Okikurmi was a divine culture-hero who descended from the heavens to teach humans the arts of hunting, fire-making, and grain cultivation. The first hill is said to be the site of his chashi (fortified residence). The second, Muinoka, takes its name from "mui," a winnowing basket; legend holds that it formed when Okikurmi's wife left her basket on the earth as she returned to the heavens. A viewing platform in the Nioi area of Biratori is set up to allow visitors to take in this layered landscape.
Visiting Pirikanoka: Practical Information
Because Pirikanoka spans the entire island of Hokkaido, no single visit can take in every component. Travelers are best served by selecting one or two sites that align with their existing route. The most accessible components for a typical traveler include: the Outer Coast of the Etomo Peninsula (within walking distance of central Muroran's transport hub), Ganboiwa in Engaru (a short walk from JR Engaru Station), Cape Erimo (reached by bus from Obihiro or Hidaka via the scenic coastal Route 336), and the Okikurmi viewpoint in Biratori (best combined with a visit to the Nibutani Ainu Cultural Museum). Hikers and mountaineers will find Tokachi-Poroshiri-dake and Poroshiri-dake to be serious undertakings requiring proper equipment, experience, and—in the case of Poroshiri-dake—advance permits.
The components are best visited from late spring through early autumn, when alpine paths are open and weather is most favorable. Coastal sites such as Cape Erimo and the Etomo Peninsula are dramatic year-round but can be very windy and cold, particularly in winter.
Surrounding Attractions
Many Pirikanoka components are located near major cultural and natural attractions of Hokkaido. In Biratori, the Nibutani Ainu Cultural Museum and the Kayano Shigeru Nibutani Ainu Memorial Museum offer in-depth exhibits on Ainu daily life, language, and spiritual practice. In Muroran, the Etomo Peninsula viewpoints can be combined with the city's industrial-era heritage and night views from the Hakuchō Bridge. Cape Erimo neighbors the Erimo Cape Wind Museum, which interprets the area's famous winds and the seal colony offshore. Nayoro is home to the SunPillar Park observatory, a fitting partner for the cosmic atmosphere of Kudosan. For those exploring deeper Ainu heritage, the Upopoy National Ainu Museum at Lake Poroto in Shiraoi—Japan's national center for Ainu cultural revitalization—offers an indispensable wider context.

Q&A
- What does the name "Pirikanoka" mean?
- Pirikanoka is an Ainu phrase combining "pirka" (beautiful) and "noka" (shape or form). It serves as a collective name for outstanding scenic landscapes whose beauty is intertwined with Ainu language, oral literature, and spiritual practice.
- Are all ten Pirikanoka sites located near each other?
- No. The sites are widely scattered across Hokkaido, from northern Nayoro to southern Erimo and from the Sea of Japan coast to the Sea of Okhotsk. Each component must be visited separately, and most travelers focus on one or two components within their planned route.
- When was Pirikanoka first designated, and is the designation still growing?
- The initial designation took place on July 23, 2009, with two component mountains—Kudosan and Koganeyama. Additional components have been added in stages, and as of the most recent rounds of additions, ten sites are included in the property. Further additions remain possible as research continues.
- Which Pirikanoka component is easiest to visit by public transport?
- Ganboiwa (Inkarushi) in Engaru is among the most accessible: a short walk from JR Engaru Station leads to a parking area near the summit, and the view over the town and the Yubetsu River is reached on foot in a few minutes. Sections of the Etomo Peninsula in Muroran are also well served by city transport.
- Do I need special permission or a guide to visit?
- For most viewpoint-based components, no special permission is required. However, climbing Poroshiri-dake (the highest of the Hidaka peaks) requires advance application due to access controls on the approach road, and full mountaineering experience and equipment are essential. Some sites have visitor platforms set up by local governments to provide context and protect the underlying landscape.
