Origins and Historical Records of Miyajima’s Deer<\/h2>\nDeer on the Island Since the J\u014dmon Period<\/h3>\n
Miyajima’s deer trace their origins back approximately 6,000 years to the J\u014dmon transgression\u2014a period when rising sea levels separated the island from mainland Honshu. Deer populations that had been living in the area became isolated on the newly formed island. Recent genetic research confirms that Miyajima’s deer are closely related to deer in Hiroshima and Yamaguchi prefectures, scientifically disproving the popular myth that they were brought from Nara.<\/p>\n
Deer are also capable swimmers, so some individuals may have crossed the sea to reach the island even after its formation. As the mainland deer population’s range shrank and they no longer inhabited the area across from Miyajima, the island’s deer became isolated and began their own evolutionary path.<\/p>\n
Deer in Historical Documents<\/h3>\n
The earliest reliable record of Miyajima’s deer appears in the Senj\u016bsh\u014d<\/em>, a Buddhist text from the Kamakura period. The poet-priest Saigy\u014d, who visited the island about 820 years ago, noted that many deer already lived there\u2014indicating a substantial population existed by the late Heian period.<\/p>\n During the Edo period (1603\u20131868), Miyajima flourished as a popular destination for travelers, scholars, and monks. The warlord Fukushima Masanori composed a poem about hearing the cry of deer, while the celebrated haiku poet Masaoka Shiki wrote of deer walking through autumn leaves in Momijidani valley. In 1715, a monk named Joshin included the deer as one of the “Eight Views of Itsukushima”\u2014testament to their importance in the island’s identity.<\/p>\n The deer’s long history of protection stems from Miyajima’s sacred status. Traditional beliefs held the entire island to be holy ground, with strict taboos against bloodshed. Just as women historically traveled to the mainland for childbirth to avoid blood pollution on the island, killing deer was strictly forbidden as an act that would spill blood. This religious prohibition effectively protected the deer for centuries.<\/p>\n Although the island experienced upheaval during the Meiji-era separation of Shinto and Buddhism, in 1879 the Hiroshima prefectural governor designated all of Miyajima as a no-hunting zone to protect the deer. After World War II, when deer numbers had declined sharply, the former town of Miyajima enacted a deer protection ordinance in 1949, prohibiting the killing of deer and the keeping of dogs\u2014with penalties for violations. These protective measures continue today under Hatsukaichi City.<\/p>\n For more about the religious background of deer as divine messengers:<\/p>\n 2025.09.15<\/p>\n 2025.10.05<\/p>\n<\/p><\/div>\n Many visitors to Miyajima are captivated by the deer that greet them along the path to Itsukushima Shrine. Their elegant, almost mystical presence naturally raises the question: why are deer considered messengers of the gods…<\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n The most striking feature of Miyajima’s deer is their smaller stature compared to mainland Japanese sika deer. While typical male sika deer develop antlers with four points by age four or five, Miyajima’s males have smaller antlers with considerable variation between individuals.<\/p>\n This smaller size isn’t the result of malnutrition\u2014it’s an adaptation to living at extremely high density. Miyajima’s deer population density reaches about 100 deer per square kilometer. For context, mainland deer populations typically cause noticeable environmental impact at densities below 10 per square kilometer. By developing smaller bodies that require less food, Miyajima’s deer have found a way to survive on the island’s limited vegetation.<\/p>\n Research shows that over 80% of mature females reproduce successfully each year, giving birth to healthy fawns. Despite their smaller size, these deer maintain robust health and continue breeding generation after generation.<\/p>\n Miyajima’s deer population divides into two main groups: those that spend most of their time in the mountains (including at night), and those that have settled in the town area. Among the mountain deer, some are wary of humans, while others follow what locals call the “deer commute”\u2014descending to town in search of food during the day and returning to the mountains at night.<\/p>\n The number of deer seen in town varies seasonally, with fewer appearing from summer to autumn and more from autumn through early spring. This pattern relates to food availability in the forest and is also influenced by biting flies that drive deer away from certain areas.<\/p>\n Normally, sika deer maintain individual territories and rarely venture beyond them. However, years of human feeding in the town area have caused male deer to become more sedentary instead of dispersing as they mature. This means males often remain in the same area as their mothers and sisters, raising concerns about potential inbreeding.<\/p>\n Like goats and cattle, Miyajima’s deer are ruminants that can digest cellulose-rich plants. They subsist on low-calorie grasses, lawn grass, seaweed, and moss. You might even spot them wading into the water at high tide to eat eelgrass.<\/p>\n Visitors sometimes see deer eating paper\u2014this isn’t desperation but rather because paper contains cellulose. However, this behavior is risky: deer may accidentally ingest printed ink, plastic bag handles, or other harmful materials. Deer that have learned the taste of human food often can’t distinguish between food and garbage, leading them to swallow anything with an appealing smell\u2014which can cause serious health problems.<\/p>\n The expansion of transportation networks, including the Shinkansen, brought increasing numbers of tourists to Miyajima during the 1960s and 70s. Vendors began selling “deer crackers” (similar to those in Nara), and the deer population is believed to have surged during this period. By around 1965, more deer were living in the town center, and problems emerged: the smell of deer droppings, deer eating food from shops, and increased conflicts with residents.<\/p>\n When deer populations grow too large, they consume the low-growing trees and ground vegetation that prevent soil erosion. Miyajima’s geology\u2014mostly granite that weathers easily\u2014makes its slopes particularly prone to collapse. Much of the town area is already designated as “steep slope collapse hazard zone” or “debris flow risk area,” and the loss of vegetation increases the danger of landslides.<\/p>\n In 2006, the Ministry of the Environment conducted a survey documenting significant deer damage to local vegetation. The following year, Hiroshima Prefecture carried out a comprehensive deer population survey across the island and produced a management report recommending a feeding ban.<\/p>\n In 2007, the sale of deer crackers was banned on the island. In 2008, Hatsukaichi City established the “Miyajima Area Deer Countermeasures Council,” bringing together local stakeholders and academic experts. Based on monitoring surveys and resident input, they developed the “Miyajima Area Deer Protection and Management Plan.” A second phase of this plan was implemented in 2014.<\/p>\n The plan’s basic principles include comprehensive measures covering population management, habitat conservation, and damage prevention. Transparency in planning procedures and building consensus across the community are also emphasized. The plan was developed with input from local residents and has the support of Hiroshima Prefecture.<\/p>\n Population trends show some decline after the 2007 cracker ban, particularly around 2010, but numbers increased again between 2015 and 2018. Monitoring in the town center showed relatively stable numbers until about 2012, followed by fluctuations in subsequent years.<\/p>\n Since the feeding ban, some visibly thin deer have been observed, prompting animal welfare concerns. Some individuals conduct unauthorized feeding out of compassion, creating tension between administrators and citizens.<\/p>\n Meanwhile, unauthorized feeding\u2014despite being prohibited by both the prefecture and city\u2014continues to cause problems. Issues include: health damage from inappropriate foods like rice bran, sweets, and corn that don’t suit deer digestion; damage to lawn areas from vehicles entering restricted zones to distribute feed; traffic accident risks when food thrown from moving cars teaches deer to chase vehicles; tree death from excessive nitrogen in concentrated droppings; and risks of introducing plant diseases, pests, or genetic contamination through feed brought from the mainland.<\/p>\n Hatsukaichi City and the Miyajima Tourism Association emphasize that “deer are wild animals,” urging visitors not to feed them and to take all garbage home. Unlike Nara, where traditional deer antler-cutting ceremonies have become tourist events, Miyajima’s antler removal is conducted quietly by city officials as a safety measure and is not open to the public.<\/p>\n Over approximately 6,000 years, Miyajima’s deer have become an integral part of the island’s natural environment and cultural heritage. Protected for centuries by religious taboos against killing on sacred ground, today they are managed as wildlife while remaining an important tourism asset.<\/p>\n Even though these deer appear comfortable around people, they are not pets\u2014they’re wild animals. They can act unpredictably, and males with antlers or females with fawns require particular caution. Residents have reported being poked by antlers, kicked, and bitten. Deer that have lost their fear of cars also face greater risk of traffic accidents.<\/p>\n Miyajima’s traditional houses still use special sliding doors called shikado<\/em> (deer doors) to keep deer from entering. Because deer push forcefully, these doors are designed to open only by pulling. This practical innovation reflects centuries of wisdom about living alongside deer since the Edo period.<\/p>\n Maintaining an appropriate distance\u2014neither too close nor too far\u2014is the key to sustainable coexistence. Both the World Heritage Site and the deer are irreplaceable treasures of Miyajima. Ensuring that deer can live healthily as wild animals in their natural environment, and passing this legacy to future generations, is essential. Visitors to Miyajima are asked to keep a respectful distance from deer, refrain from feeding them, and never leave garbage behind.<\/p>\n Approximately 500 deer currently live on the island, with about 200 in the town area. Numbers fluctuate seasonally and year to year, and have varied since the 2007 feeding ban was implemented.<\/p>\n Their smaller size is not due to malnutrition but is an evolutionary adaptation to living at very high population density. By developing smaller bodies that require less food, the deer can survive on the island’s limited vegetation. The reproduction rate remains over 80%, with healthy fawns born each year.<\/strong><\/p>\n Feeding causes several problems: deer that learn to expect human food approach people too closely, increasing injury risk; human food is unhealthy for deer digestion; deer lose their fear of traffic, leading to accidents; and they may eat garbage, mistaking it for food. The ban protects both deer welfare and visitor safety.<\/p>\n No\u2014genetic research has confirmed that Miyajima’s deer are related to deer in Hiroshima and Yamaguchi prefectures, not to Nara’s deer. The popular story that they were brought from Nara is a myth. Miyajima’s deer have been isolated on the island since it formed about 6,000 years ago.<\/p>\n June and July<\/strong> are the peak months for fawns. If you visit during this time, you may see adorable young deer. However, keep extra distance from mothers with fawns, as they can be protective and unpredictable.<\/p>\n The biggest difference is how they’re managed and perceived. Nara’s deer are treated as sacred messengers of Kasuga Grand Shrine, with traditional ceremonies open to tourists and deer crackers sold officially. Miyajima emphasizes that its deer are “wild animals”\u2014deer crackers are banned, and antler-cutting is done privately as a safety measure, not as a public event.<\/p>\n It’s best to avoid touching them.<\/strong> Deer may carry ticks and other parasites, and they can react unpredictably to contact. For photos, maintain a respectful distance without startling the deer. Be especially cautious around males with antlers and females with fawns.<\/p>\n Miyajima’s deer have lived on the island for approximately 6,000 years, developing unique adaptations to their environment\u2014including smaller bodies, high reproduction rates, and seasonal movement patterns that demonstrate their resilience as wild animals.<\/p>\n Historically protected by religious beliefs about the sacred island, today’s deer are managed under a comprehensive plan centered on prohibiting feeding while balancing animal welfare with environmental protection. Finding this balance remains an ongoing challenge.<\/p>\n When visiting Miyajima, understanding that these are wild animals\u2014and following the rules of not feeding them, not leaving garbage, and keeping an appropriate distance\u2014helps ensure that humans and deer can continue to share this remarkable island. The deer wandering freely across a World Heritage Site, living in harmony with nature, will remain one of Miyajima’s most distinctive treasures for generations to come.<\/p>\n![\"Deer](\"https:\/\/japan-stroll.com\/miyajima\/jp\/wp-content\/uploads\/2025\/10\/shika003.jpg\")
