This diver sought out the wreckage of a sunken battleship alleged to be from the Russo-Japanese war over a century ago.
The ancient naval remnants were found in the Sea of Japan heavily rusted and growing aquatic plant life on from bow to stern.
The filmer explained: "According to archives, this is the steamship destroyer N208."
It was sunken in 1904, according to the filmer's research.
The footage was captured on February 10.
