❶  I would like to recommend the Ogasawara Islands, which are located about 1,000 km south of Tokyo. . ❷  They have many geographic features, such as limestone terrain and endemic species.  In addition, they were added to the World Heritage list in 2011. . ❸  Various rules have been set up with the purpose of protecting the natural assets and managing them properly.  One such example is “the Ogasawara Country Code,” which is a guideline for coexistence with nature.  It has rules and etiquette that should be followed by all those who visit the Ogasawara Islands.
