The Mysterious Object Discovered by Fishermen 00:00

  • In February 1803, a group of fishermen, including a man named Kiichi, encountered an object in the waters off Harayadori in Japan.

  • The fishermen initially believed it might be debris or a capsized hull, but as they approached, it became clear that the object was unlike anything they had ever seen before.

  • The object was unusually large, measuring about 11 feet tall and nearly 18 feet across, and had a distinct round shape. Its top half was made of a fine wood coated in a reddish lacquer, while the bottom half was constructed from heavy metal plates bound together with rivets, indicating a craftsmanship that was far too advanced for the time.
