Answer: Japan
Notes: The iconic Mount Fuji in Japan has witnessed a dramatic increase in visitors, with over 5.1 million tourists between 2012 and 2019. This has led to concerns about ecological damage and safety risks to the mountain ecosystem. Visitors, including those climbing at night to witness the sunrise, have overwhelmed the region. Facilities catering to tourists rely on diesel generators, leading to environmental concerns, while overcrowding and breaches of etiquette have become common.
