The Kensho Maru is a wreck dive located in Chuuk Lagoon, Micronesia. Resting at depths between 12 and 40 metres, the site offers varied topography suitable for intermediate divers. Visibility typically ranges from 10 to 30 metres, providing clear sightlines along the hull. The site features mild currents, though divers must manage overhead environments and potential entanglement hazards within the structure. Water temperatures remain consistent between 29 and 30 degrees Celsius throughout the year. Access to the site is by boat only. Divers should exercise caution regarding deep diving protocols and nitrogen narcosis risks, and carry torches for any interior penetration.

The Kiyosumi Maru is a shipwreck located in Chuuk Lagoon, Micronesia, resting at depths between 12 and 37 metres with an average depth of 25 metres. This wreck serves as an artificial reef, and species recorded around this area include bluefin trevally, horse eye jack, and various wrasses. Access is by boat only, and the site is suitable for intermediate divers. Visibility typically ranges from 10 to 30 metres, with mild currents and water temperatures between 29 and 30C. Divers should be aware of hazards including deep water, entanglement risks, overhead environments, and sharp coral.

The Shinkoku Maru is a Japanese tanker sunk during Operation Hailstone in 1944, resting upright on the floor of Chuuk Lagoon. The wreck offers a wide range of depths, with the shallowest structure at 11 metres and the hull reaching 40 metres. Divers encounter mild currents and visibility ranging from 12 to 38 metres. The superstructure is colonised by coral and supports a diverse reef ecosystem. Due to the depth and potential for entanglement within the engine room and cargo holds, this site is suited for intermediate divers. A torch and reel are recommended for penetration, and divers should monitor bottom time carefully to manage nitrogen narcosis.

The Emily Flying Boat is a Japanese Kawanishi H8K aircraft resting upright on a sandy bottom in Chuuk Lagoon. Situated at a depth of 15 to 16 metres, the wreck is accessible to intermediate divers. Visibility typically ranges from 15 to 20 metres, allowing for clear views of the fuselage and gun turrets. The airframe is covered in coral growth. Divers should be aware of sharp coral and significant entanglement hazards near gun blisters and open hatches. Access to this site is by boat only, with mild currents generally present. Species recorded around this area include wrasses, blue dragon, and various damselfish.

The Betty Bomber is a wreck dive located in Chuuk Lagoon, Micronesia, resting at a depth of 17 to 18 metres. This site is accessible by boat and features mild currents, making it suitable for beginner divers. Visibility typically ranges from 10 to 30 metres, allowing for clear views of the aircraft structure. Water temperatures remain consistent between 29 and 30 degrees Celsius throughout the year. Divers should be aware of potential hazards, including entanglement risks within the airframe, sharp edges on the wreck, and the occasional presence of jellyfish. Full skin suits or light wetsuits are recommended for protection and thermal comfort during the typical 45-minute dive.

The Fujikawa Maru is a Japanese armed merchant vessel resting on the floor of Chuuk Lagoon. The wreck serves as an artificial reef, with the shallowest structure at 9 metres and the hull reaching 36 metres. Divers experience mild currents and visibility ranging from 10 to 30 metres. This site is suitable for intermediate divers, though penetration of the interior requires a torch and reel due to entanglement risks and overhead hazards. Guided tours and equipment rental are available. Night diving is permitted, offering a different perspective on the vessel. Given the depth and overhead environment, advanced and wreck certifications are required for those planning to explore the interior.

The Unkai Maru is a deep wreck located in Chuuk Lagoon, Micronesia, resting at depths between 30 and 40 metres. This site is suited for advanced divers with wreck certification due to the overhead environments and entanglement hazards found throughout the structure. Visibility typically ranges from 10 to 30 metres, allowing for views of the hull silhouette. Currents are generally mild, though divers should maintain disciplined buoyancy when navigating the interior. Access is by boat only, and divers are advised to carry a surface marker buoy and a torch for exploring the deeper, darker sections of the wreck. The average dive duration is approximately 40 minutes.
