If you plan to stay the night, no place is better than a temple lodging where you can experience some of the spiritual practices of Mount Koya. There are 52 of these lodgings (shukubo) within the complex, and they all offer breakfast and supper, featuring carefully prepared dishes of traditional shojin ryori vegetable origin meals. Early in the morning you can participate in a religious service when sutras are chanted and rituals of veneration are performed before an altar. At some lodgings you can try your hand copying a sutra, or you can meditate in the Ajikan way, following the Shingon Buddhist practice of sitting in the lotus position and focusing on your breath. Surrounded by nature in this tranquil part of Japan, your spiritual practice can bring a revitalizing peace of mind you may not experience anywhere else.
Along both sides of the national highways that run eastwest past the temples are shops selling food, drink, Japanese confections and souvenirs. For souvenirs you may want to look at the goma-dofu (sesame paste kneaded with kuzu powder to make a firmly set delicacy often used in shojin-ryori), confections, and items unique to a religious place, like juzu prayer beads and shuincho notebooks for holding impressions of the red seals of temples and shrines.
For some quiet moments during your travels, this sacred spot not far from the heavens may be ideal.
