Tateyama Maru

Local Name:

K-5 Side


While approximately 80 feet to reach the hull, the bottom is a little over 130 feet.

Length and Orientation info:

The approximate length and approximate orientation of the ship are deteremined based on the lat and lon of the bow and stern. Typically, the lat/lon information was obtained by attaching a line with a float to the wreck and marking the position of the float with a handheld GPS receiver. We try to get the line as near vertical as possible, but there is bound to be some error. Also, the GPS position will have a certain error in it as well. So, this information will be reasonable, but not 100 percent accurate.

Stern Position:
Latitude : 8 deg 44.443 min 0 sec

The scuba club generally maintains a sub-surface and surface buoy on this wreck. If intact, there should be tag line attached to the surface buoy to tie off on. As always, I'd bring a second anchor down and tie into the wreck just in case!

This ships is facing roughly northeast and lies on its' starboard side. Just behind the main cabin area there is a hold loaded with large shells. They appear to have been in crates of 4. Each shell is maybe on the order of 4 or 5 inches in diameter. Hundreds of these shells are spilling out of the hold!

There are gun mounts toward the bow and stern, but no guns are present.

Several anemones can be found along the ship if you look closely.


One of the more popular sights to see on this wreck is the ammo filled hold! It is just behind the main cabin area and in front of the stern gun. Since the ship is laying on its' starboard side, the cargo of ammo crates is now spilling out of the hold. It should go without saying, but this is a place to look and not touch!
Here's Doug Curry during our safety stop.

The kingposts are seen here now resting almost horizontal.
This must have been paradise for porthole hunters when wreck diving started cathing on at Kwajalein!
