On the first weekend of the new year, we visited a campground at the foot of Mount Fuji. Despite the sub-zero temperatures, people kept arriving and setting up tents. Winter camping is popular because “the air is clear and the scenery is beautiful” and “there are no bugs.” A company employee came alone for “solo camping.” A 50-year-old veteran camper showed off his favorite gear. The campground is buzzing with excitement over the boom that has returned after more than 20 years. What are everyone's thoughts as they gaze at Mount Fuji?
