The Japanese sea turtle, also known as the loggerhead turtle (*Caretta caretta*), is a marine reptile found in the waters around Japan. These turtles are known for their large heads and strong jaws, which help them feed on hard-shelled prey like crabs and mollusks. They are typically found in coastal areas and are known to migrate long distances between feeding and nesting sites. Japanese sea turtles are classified as endangered due to threats such as habitat loss, pollution, and entanglement in fishing gear. Conservation efforts are underway to protect their nesting sites, particularly on beaches like those in the Okinawa region. These efforts aim to ensure the survival of this important species in the marine ecosystem.
