Wait, I found it in the Honolulu Advertiser:

Japanese sub's wreckage found

University of Hawai'i scientists have discovered the wreckage of a large World War II-era Japanese submarine in waters off O'ahu.

A Hawaii Undersea Research Laboratory submersible found the Japanese I-401 during test dives Thursday.

John Wiltshire, acting director of the laboratory, said the submersible Pisces discovered the sub 820 meters below the surface off Kalaeloa.

The vessel is from the I-400 Sensuikan Toku class of subs, the largest built before the nuclear ballistic missile submarines of the 1960s. They were 400 feet long and nearly 40 feet high and carried a crew of 144.

They were designed to carry three fold-up bombers, which could be made ready to fly in a few minutes and had wing floats for return landings. Fully loaded with fuel, the submarines could sail 37,000 miles. An I-400 and I-401 were captured at sea a week after the Japanese surrendered in 1945. Their mission was never completed.

The discovery is the laboratory's second Japanese vessel found off O'ahu.

In 2002, the crew found the wreckage of a Japanese midget sub that was sunk on Dec. 7, 1941, off Pearl Harbor.
