Site Overview

Japanese Sweeper Wreck (Gizo) is one of the signature dive sites of Gizo & Ghizo Island in the Solomon Islands. The Japanese Sweeper Wreck is a shallow small-boat wreck off Gizo, an ideal beginner wreck and macro-photography site draped in coral and small life. The site reaches a maximum depth of about 15 m, with an average depth near 12 m, and its wreck topography is draped in metal and coral. Marine life is the headline attraction, with nudibranch, lionfish, moray eel, soft coral, glassfish, ghost pipefish regularly recorded here, drawn in by the mild currents and the rich Coral Triangle productivity of the region. Visibility typically ranges from 12 to 25 m, while water temperatures hold a consistent 27 to 30°C year-round, comfortable in a 3 to 5 mm wetsuit. Conditions suit beginner divers, and with the right guide the site delivers both the drama of its wreck and intimate encounters with the smaller residents. Local operators run regular trips from Gizo, and the protected, low-tourism setting keeps coral cover dense and fish life abundant, making Japanese Sweeper Wreck (Gizo) a genuine standout on any Solomon Islands itinerary. Divers who time their visit to the calm season will find the most predictable conditions, though the site rewards repeat visits across the year.

Dive Briefing

"The dive at Japanese Sweeper Wreck (Gizo) begins with a thorough operator briefing covering the site layout, expected marine life and emergency procedures, followed by a controlled entry and a short transfer from Gizo. Descending toward the wreck profile, divers are immediately surrounded by nudibranch, lionfish, moray eel, soft coral, glassfish, ghost pipefish, with the reef and structure revealing more detail the closer you look. The maximum depth reaches about 15 m while the average sits near 12 m, so a dive computer and disciplined gas planning keep the profile safe and comfortable. Currents are described as mild, and the guide chooses the entry time to make the most of slack or mild flow, using a reef hook or DSMB when needed. Neutral buoyancy protects the fragile coral and the group stays close to manage depth and any surge. The safety stop is completed in open water on a DSMB, and the boat follows the bubbles to collect divers at the exit point for a relaxed return to base. The Japanese Sweeper Wreck is best dived as a very shallow dive on a calm day, when the small boat and its macro residents are easiest to photograph. The 8 to 15 m depth gives huge bottom time. Water stays 27 to 30°C, and a 3 mm wetsuit is plenty. A slack-window dive keeps the water clear."
