Fujikawa Maru Wreck: Truk Lagoon's iconic cargo ship

Descending onto the Fujikawa Maru, you find a vessel that settled upright, a significant difference from many other wrecks in the lagoon. The mast rises from a maximum depth of 37 metres to a shallowest point of 5 metres, making the wreck accessible across a broad depth range. This orientation allows you to approach the structure much like an artificial reef, with the superstructure and deck areas providing a clear profile to navigate, guiding your descent along the hull.

As you move deeper, the sheer size of the Fujikawa becomes apparent. The main deck, bridge, and hold areas are largely intact, giving a clear sense of the ship’s original layout. Penetration routes are available into the cargo spaces and machinery rooms, offering a different dimension to the dive for those with the appropriate training and experience. The light filters down, revealing the growth that now covers the steel, transforming the man-made structure into a vibrant living reef.

The holds of the Fujikawa Maru are what truly set this wreck apart. Within them, you encounter Mitsubishi Zero fighter aircraft, along with various aviation parts. It's a preserved snapshot from another time, providing a stark contrast between the military hardware and the biological colonisation. These aircraft are a signature feature, allowing you to witness history in a way few other sites can offer, nestled amongst the soft corals and sponges.

Beyond the historical cargo, the wreck acts as a substantial artificial reef, attracting a significant amount of marine life. Hard and soft corals, sponges, and algae have heavily encrusted the hull, deck, and superstructure. This extensive overgrowth creates a complex ecosystem, providing shelter and feeding grounds for a variety of resident species, making the structure a focal point for biodiversity within the lagoon.

As you explore the exterior, keep an eye out for larger pelagic species that patrol the perimeter. Barracuda and various species of jack, including trevally, are often seen schooling off the wreck. Grey reef sharks can also be spotted cruising in the blue, adding a dynamic element to the dive. Sea turtles are occasional visitors, grazing on the corals or resting on parts of the wreck, blending into the intricate structure.

The mixed tropical reef fish population adds constant colour and movement to the wreck. Anemones, sponges, and a multitude of soft corals create a diverse backdrop, where you might observe smaller creatures hiding within the crevices of the ship’s structure. This blend of metal and marine growth ensures that every section of the Fujikawa Maru offers something different to observe, from macro life to the scale of the wreck itself.

While the visibility typically ranges between 20 to 30 metres, allowing for clear views of the wreck's expanse and its inhabitants, the conditions inside Chuuk Lagoon are generally calm. The protected environment of the atoll means currents are usually light. This contributes to making the Fujikawa Maru accessible for extended exploration, allowing time to absorb the details of this significant historical and ecological site without battling strong flows.
