Why dive here
With 176+ marine species recorded in the area - including giant moray eels, sea turtles and pufferfish - ASOGAWA MARU (POSSIBLY) offers some of Nha Trang's richest wreck diving. Water ranges 25-30°C, warmest May, June, September.
The *Asogawa Maru* (or what we strongly suspect is her) lies on a sandy bottom at 26 metres, and for Nha Trang, she’s a standout. This isn't one of those wrecks picked clean by time; she still holds her shape, a proper skeleton of a ship. We love dropping down and watching her emerge from the blue, a dark silhouette slowly taking on detail: the massive propeller, the remains of the superstructure, the sheer scale of it all. Exploring the *Asogawa Maru* feels like stepping back into a moment in time. There’s a quiet solemnity to it. You can swim through the holds, imagining cargo long gone, and poke around the engine room, which is still remarkably intact. Schools of fusiliers often swirl around the masts, and we’ve seen some seriously chunky groupers lurking in the deeper shadows. Keep an eye out for the resident moray eels peeking from every crevice. Our top tip? Go early. You might just have her all to yourself, and the visibility tends to be at its best before the day boats arrive.
