About Shinkoku Maru
Shinkoku Maru is a classic Chuuk Lagoon tanker wreck with a broad superstructure, colorful coral growth, and a mix of easy exterior exploration plus deeper sections for divers who want more of the ship. The bridge, medical bay, and engine spaces make it one of the lagoon’s most interesting wrecks, but the site still rewards careful buoyancy and a clear plan. Treat it as a boat dive that suits the certification and wreck-comfort level of your group.
