Palawan, widely recognized as the “Last Frontier” of the Philippines, offers much more than breathtaking beaches and impressive limestone cliffs. Hidden beneath its clear turquoise waters is a rich history waiting to be uncovered. One captivating aspect of this history is the wreck of the Okikawa Maru, a Japanese oil tanker that sank during World War II. Today, the rusting remains of the vessel lay submerged in Coron Bay, evolving into a flourishing artificial reef that attracts diving enthusiasts worldwide. Dive in to explore the wonders locked beneath the surface!
A Closer Look at the History of the Okikawa Maru
The Okikawa Maru’s journey began in 1936, when it was constructed as a key oil tanker for the Imperial Japanese Navy during World War II. The ship played an important role in transporting fuel essential for military operations throughout Southeast Asia. Sadly, its service to the war effort made it a target. On September 24, 1944, during a series of attacks by the United States Navy Task Force 38, the Okikawa Maru joined other ships in sinking to the bottom of Coron Bay.
Today, the wreck is positioned almost entirely upright, resting at depths that range from 10 to 26 meters (33 to 85 feet). At an impressive length of 168 meters (551 feet), it is one of the largest wrecks in Coron Bay. This significant size makes it accessible to divers of various skill levels, catering to both beginners and experienced wreck divers alike.
Diving at the Okikawa Maru: An Underwater Adventure
Experiencing a dive at the Okikawa Maru feels like stepping into a living history book. As you dive deeper, the grand silhouette of the ship gradually comes into view, offering an awe-inspiring sight. The exterior of the wreck is adorned with a colorful array of corals, sponges, and various marine life, transforming it into a vibrant underwater habitat.
The relatively shallow depths and generally favorable visibility make this dive site perfect for those interested in exploring the ship’s interior. The ship has several large apertures that allow divers to safely navigate through its holds and passageways. Be sure to look for artifacts that signify its past, like old pipes, valves, and even some remnants of wartime machinery. However, always keep in mind the importance of not removing or tampering with anything from the wreck. It’s essential to preserve the heritage of this site for future divers.
Inside the wreck, you’ll encounter various species of marine life that have settled there. Schools of batfish, trevally, and snappers frequently swim around the wreck. If you take a moment to look closely, you may spot tiny nudibranchs, scorpionfish, and other small creatures nestled within the corals. Sea turtles often make an appearance, using the wreck as a resting spot during their underwater journeys.
