99 Handgun Cartridges Found Near Okinawa’s Iconic Blue Cave
(Ryukyu Broadcasting)
Imagine diving into the turquoise waters of one of Japan’s most breathtaking natural wonders, only to stumble upon something straight out of a thriller novel. That’s exactly what happened on September 18, 2025, when a tourist snorkeling near Okinawa’s famed Blue Cave uncovered a mysterious bag containing what authorities suspect are 99 live handgun cartridges. This unexpected find has sparked curiosity and a touch of unease among locals and visitors alike, highlighting the unpredictable side of paradise destinations.
The incident unfolded around 5:40 PM in the waters off Cape Maeda in Onna Village, Okinawa Prefecture. According to police reports, the snorkeler spotted a zippered plastic bag tightly wrapped in duct tape, designed to conceal its contents. Inside were the cartridge-like objects, neatly packed and submerged in a popular swimming area just 300 meters southeast of the Blue Cave’s entrance. The tourist wisely avoided handling them further and alerted authorities, who quickly retrieved the items for detailed analysis. Police have urged the public not to touch any suspicious finds and to report them immediately, emphasizing safety in this bustling tourist hotspot.
For those unfamiliar, the Blue Cave—known locally as “Ao no Dokutsu”—is a stunning sea cave carved into the cliffs of Cape Maeda. Its name comes from the ethereal blue glow created by sunlight filtering through the water, illuminating the cavern in a mesmerizing sapphire hue. This natural phenomenon draws thousands of visitors daily, making it one of Okinawa’s top attractions for snorkeling, diving, and kayaking. The surrounding area, part of the Okinawa Kaigan Quasi-National Park, boasts vibrant coral reefs teeming with tropical fish, sea turtles, and colorful marine life. It’s a slice of tropical heaven that embodies Okinawa’s allure as a subtropical escape from mainland Japan’s hustle.
From a local perspective, this discovery hits close to home. Okinawa has a complex history, marked by its role in World War II and the ongoing presence of U.S. military bases. Residents often deal with remnants of the past, like unexploded ordnance from the Battle of Okinawa, which claimed over 200,000 lives in 1945. However, initial assessments suggest these cartridges are modern, not wartime relics, leading to speculation about possible smuggling or criminal activity. Longtime Onna Village locals, many of whom rely on tourism for their livelihoods, express mixed feelings. “We’ve seen all sorts of things wash up over the years, but this feels different—more deliberate,” shared a dive shop owner who preferred anonymity. The island’s strategic location in the East China Sea has occasionally raised concerns about illicit activities, but events like this are rare. Community leaders are quick to reassure that Okinawa remains one of the safest places in Japan, with low crime rates and a welcoming spirit rooted in “Ichariba Chode,” the Okinawan proverb meaning “once we meet, we are brothers and sisters.”
This event underscores the importance of vigilance in natural environments. Tourism is the lifeblood of Okinawa’s economy, contributing billions annually and supporting everything from family-run ryokans to adventure outfitters. In 2024 alone, the prefecture welcomed over 10 million visitors, many flocking to sites like the Blue Cave for its Instagram-worthy vistas. Yet, discoveries like this serve as a reminder to respect the ocean’s mysteries. Environmental groups advocate for sustainable practices, noting that marine debris—from plastic waste to abandoned gear—poses risks to both wildlife and humans. Police investigations are ongoing, with forensic tests to determine the cartridges’ origin, caliber, and authenticity. No arrests have been made, and there’s no immediate threat to public safety, but it has prompted enhanced patrols in popular coastal areas.
As the investigation unfolds, we’ll keep an eye on developments. For now, the Blue Cave remains open, inviting adventurers to experience its magic. Just remember: in paradise, a little caution goes a long way.
