Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
Once a collection of three formidable Japanese cargo vessels – the Kolusei Maru, Hiyori Maru, and Higane Maru – the Usukan Bay wrecks, including the Rice Bowl Wreck, faced a dramatic end. Torpedoed by the American submarine USS Hammerhead in 1944, these 5300-ton ships carried significant human loss, with 138 fatalities reported.
Hundreds of ceramic bowls in its cargo earned the 'Rice Bowl Wreck' its distinctive name. Until recently, these wrecks were described as an underwater museum, boasting rich coral growth and abundant marine life.
However, recent years have seen extensive salvage operations, leaving behind a vastly altered landscape. Today, the site consists primarily of scattered metal debris and a burgeoning artificial reef, transforming what was once a ship into a habitat for diverse fish schools and larger pelagics. It's an eerie dive, a testament to both historical events and natural resilience.

Dive Experience & Conditions
Descending into the deep blue reveals what remains of this once-intact wreck: a ghostly seabed littered with large chunks of metal. What was once an original structure, a complete vessel, now forms an unrecognisable 'heap of metal piled up into a ball,' as described by some divers. Despite this, an artificial reef has flourished around the debris, attracting a vibrant ecosystem. Water temperatures in these tropical waters generally range from 22-27°C (72-81°F). Reaching a maximum depth of approximately 30 m (100 ft), the site demands appropriate certification and gas management. Encounters with schooling barracuda and snapper are common, often blanketing the remnants of the wreck. An overall feeling of solemnity blends with the wonder of observing life adapting to an altered environment during this dive.
Dive Difficulty & Safety Guidelines
Navigating the remnants of the Rice Bowl Wreck requires careful planning and situational awareness. Due to the significant salvage activity, the site is now a collection of scattered debris and metal fragments, posing potential entanglement or collision hazards. Divers must maintain excellent buoyancy control to avoid contact with the seabed and any sharp edges. As a former war grave, approaching the site with respect and reverence is paramount; disturbing any remains is strictly prohibited. Accessing the site typically involves a 75-minute boat trip from Kota Kinabalu, covering approximately 36 miles, making reliable boat and dive operator selection essential for safety and efficiency. Strong currents are not consistently reported but can vary depending on local conditions, so staying close to your buddy and dive guide is always advisable.
