Every year, 8.6 million Japanese climb the more than 15,000 mountains and 200 volcanos, which share about 70 percent of the Japanese archipelago. In 2016, the government of Japan created a new national holiday, “Mountain Day” on August 11, to let people familiarize themselves and appreciate the blessings of mountains. So, if you want to fit in on this island, go climb yourself a mountain or two, slacker.
