Ship History
Owned by Osaka Shosen Company and placed into service in August 1930. Used as a modern fast luxury freighter traveling from Tokyo to New York.

Wartime History
Re-commissioned as a freighter under contract to the Japanese Imperial Navy in October, 1941, and was used to transport war materials and personnel throughout the Pacific.

On January 24, 1943 the Tokai Maru was observed anchored in Apra Harbor off Guam. Spotted by USS Flying Fish SS-229, the submarine waited for the ship to leave harbor and waited outside the harbor entrance for three days. When Tokai Maru failed to move, they fired two torpedoes set to run at 1' depth. One of the torpedoes ran aground on the reef, but the other struck Tokai Maru causing considerable damage, but did not sinking her.

Sinking History
Seven months later, USS Snapper was patrolling west of Guam and spotted two ships in Apra Harbor Unaware at the time that these were the damaged vessals Tokai Maru and Nichiyo Maru, the submarine patiently waited for one week, and then made a submerged attack under with enemy patrol vessels less than two miles away.

On August 27, 1943 at 3:23pm USS Snapper fired a spread of four torpedoes, three at the nearest ship, Tokai Maru and fourth at Nichiyo Maru. Afterwards, the submarine immediately headed westward into safer waters. Over the next few hours numerous explosions were heard, and the Tokai was observed with the bow at an extreme "up angle", indicating that the stern was on the bottom. A few minutes later the Tokai slipped beneath the surface, sinking into Apra Harbor.  She was sunk only six feet away from the wreck of the SMS Cormoran.

Commander M.K. Clementson recalls:
"For the next 10-15 minutes heard some very faint distant explosions undoubtedly inside the harbor and one explosion about 100 yards away (from the submarine), probably from the patrol vessel. His screws were not heard after this so it is believed possible that this nicely inefficient gent probably decommissioned himself. Departed from the area at good speed, and depth, however."

Leon Theriault adds:
“While station in Guam in 1959 with MCB5 ‘Seabees’ made a dive to the Tokai Maru, at that time there was a lot of china plates scattered along the bottom next to the wreck site, one of the other items that was salvaged%2C was a very nice looking purple marble washbasin, i still have the picture of that. at that time their didn't seem to be to much of and interest in wreck diving.  I did make more dives to that wreck.”

Shipwreck
She rests in 120 feet with an 85 degree list to port (left). The shallowest part of the ship is the upper forward bridge area at a depth of 40 feet. There is damage on the starboard bow, but this is believed to have been inflicted on the first attack in January, 1943. Visibility averages 35-40', but can vary due to the tide and large ship traffic in the harbor.

Dan Lantzy adds:
"The other photo is a bow shot of the Toki Maru. It rests in about 130 feet of water resting on it's port side. If you look close at the photo, you can see some of the damage aft of her bow on the starboard side. it was initially struck with artillery shells from a surface warship. That damage put her back in port. Later, she was struck by a torpedo via a U.S. sub. The most interesting thing about this wreck is she's actually touching SMS Cormoran."

Cargo Holds
A torpedo has blown a hole in the port #3 cargo hold, and this is undoubtedly the torpedo that sunk her. Contains remains of truck frames, beds, scrap steel, and miscellaneous objects. The engine room is huge, and both of her engines, catwalks, and panels are intact. The after deck house in the stern of the vessel contains at least 4 depth charges, which are plainly visible from the top of the structure.
