Azumasan Maru

Introducing the Azumasan Dive Site in Guadalcanal, Solomon Islands

Discover the captivating Azumasan dive site, situated approximately 150m from the shore. Although it is best explored from a boat, this dive site promises an extraordinary underwater experience for seasoned divers. The Azumasan wreck lays upright with its bow resting at a depth of 39-50m, while the stern descends to 80m and beyond. Prepare to be amazed by the vibrant colors, abundant soft corals, and remarkable photo opportunities. Don't miss the chance to capture the wreck's beauty by checking out the bow from the sand.

As you explore deeper, you'll encounter an intriguing surprise in the second hold - motorbikes and sidecars. These remnants from the past add to the historical allure of the Azumasan Maru.

Wartime History of the Azumasan Maru in the Pacific

The Azumasan Maru served as a Japanese Navy transport vessel during the Pacific War. On April 28, 1942, it departed Truk as part of "Operation MO" - the invasion of Tulagi and Port Moresby. During its journey, it was carefully escorted by a fleet of other ships, including destroyers and minelayers. Despite being targeted by carrier aircraft from the USS Yorktown CV-5, the Azumasan Maru successfully evaded hits during the attack.

On October 15, 1942, the Azumasan Maru was beached near Bunani Point on the north coast of Guadalcanal. But tragedy struck as SBD Dauntless dive bombers swiftly attacked, causing severe damage and setting the ship ablaze. The vessel, along with the Sasako Maru and Kyusyu Maru, eventually sank into deep water off Ruaniu after B-17 Flying Fortress bombers targeted the damaged ship.

Exploring the Azumasan Wreck

In the 1970s, SCUBA divers made a groundbreaking discovery - the remarkable Azumasan wreck still intact, seated in excellent condition at a maximum depth of 38m. Known locally as the "Deep Ruanui" wreck, this underwater gem offers pristine visibility of 16m that draws in majestic pelagic species. Be ready to marvel at the soft corals adorning the bow gun, creating a picture-perfect underwater scene.
