About Mountain Day in Japan
Mountain Day became a national holiday in 2016 after legislation passed in 2014, creating the first public holiday in August. Before that, Japan had no national holiday between Marine Day in July and Respect for the Aged Day in September. It falls close to Obon, the season when many people travel home, and mountain huts and hiking routes become busy.
