Ezo, also known as Hokkaido, is the second-largest island of Japan. It is often referred to as the "untamed wilderness" due to its vast, untouched natural environment. Other synonyms for Ezo are Yezo or Yesso, which was used by the Russian explorers during the 18th century. The island has a unique culture and language, and its people are known as the Ainu. Ezo is home to various wildlife species, including brown bears, red foxes, and deer. The island's rich biodiversity has been recognized by UNESCO as a biosphere reserve. Ezo provides a beautiful experience for visitors seeking a break from the hustle and bustle of Japan's urban centers.
