Located on the small island of Kabashima in Nagasaki, Shirato no Ana is a mystical sea cave said to have once housed pirates. With its mysterious atmosphere reminiscent of One Piece, it has become a beloved destination for fans. This place, where natural beauty and legend intertwine, feels like a real-world stage of adventure.
What is Shirato no Ana
Situated on the southern edge of Nagasaki City, Shirato no Ana was formed naturally as waves carved into the cliffs of Kabashima over thousands of years. The result is a large, circular cave where sunlight filters in and the sea shimmers with a mysterious blue glow.
The cave’s appearance changes with the tides and time of day. In the morning, soft golden light reflects on the walls; at noon, a deep blue fills the space; and in the evening, warm orange tones color the interior. Each visit reveals a different expression of nature’s artistry.
The Pirate Legend Behind the Cave
According to local lore, pirates once hid within Shirato no Ana. The sound of the waves masked their presence, and the cave’s concealed interior made it the perfect refuge for hiding ships, repairing vessels, or storing treasure.
Historical records from the Edo and early Meiji periods mention that smuggling ships used the cave as a secret base. Local elders also speak of traces of old fires and broken pottery fragments once found deep inside, suggesting that people indeed lived or hid there centuries ago. The site bridges the line between myth and tangible history, giving it a mysterious allure.
Why One Piece Fans Call It a “Sacred Place”
In One Piece, there are many memorable scenes of the Straw Hat Pirates gathering in secret caves to rest, plan, or hide from danger. Shirato no Ana’s appearance and atmosphere closely resemble those fictional settings. Fans often describe it as “a real-life secret base of the Straw Hat crew.”
On social media, visitors post photos with captions like “It feels like stepping right into an episode of One Piece” or “You can imagine hidden treasure here.” The spot has become a beloved destination for both fans and adventure seekers, blending pop culture and natural beauty.
