The tour was in appreciation of the United States' help following the March 11th Tokoku earthquake and tsunami.
The J. S. Kashima is docked at Pier 27 until Friday and is open to anyone who wants an up-close look at the flight deck and the 76-millimeter rapid fire gun.
The ship is a training vessel that carries over 300 crew members and 100 cadets.
Along with commemorating the unity of nations following the Tohoku earthquake, the ship is docked to commemorate the 60th anniversary of the "Treaty of San Francisco," which was signed in 1951 at the War Memorial Opera House. The treaty put an official end to World War II and the occupation of Japan.
