We took a 2-hour train ride to Koyasan (Mt. Koya) in Wakayama prefecture. Koyasan is a sacred mountain town, a UNESCO World Heritage site, founded in 816 AD by the monk Kobo Daishi and the heart of the Shingon sect of Buddhism. The area is known for its Buddhist temples and monasteries, graves of notable Shoguns and war lords, and creamy tofu made from sesame. Masami's family grave is also located in Koyasan.
