Reader's Guide
Mount Kōya in the Ito District is the headquarters of the Shingon sect of Japanese Buddhism. It is home to one of the first Japanese style Buddhist temples in Japan and remains a pilgrimage site and an increasingly popular tourist destination as people flock to see its ancient temples set amidst the towering cedar trees at the top of the mountain. The Sacred sites and pilgrimage routes in the Kii Mountain Range extend for miles throughout the prefecture and together have been recognized as Japan's 11th UNESCO World Heritage Site. The Kumano Shrines are on the southern tip of the prefecture. Wakayama Prefecture ranks first in the production of oranges in Japan. Wakayama has its own brand of oranges, which is produced in Arida District and called 'Arida-Orange'. Arida District, where oranges have been produced for more than 400 years, yields about half of the orange crops in Wakayama today. Furthermore, the yield of Arida-Oranges accounts for about 10 percent of Japanese domestic production of oranges. According to the survey by the Ministry of Agriculture, Forestry and Fisheries of Japan, Wakayama stands first in the production of Chinese flowering plum, or ume in Japanese, in Japan. As of 2016, Wakayama made up about 70 percent of Japanese domestic production of ume. Since 1996, population of Wakayama Prefecture has kept declining, and since 2010, it has been the only prefecture in Kansai region with population below 1,000,000. In the 2020 census, close to 32% of the population was over 65 years of age - the highest percentage in Japan. Wakayama Prefecture has friendship and sister relationships with six places outside Japan: Florida (United States), Galicia (Spain), Pyrénées-Orientales (France), Shandong (People's Republic of China), Sichuan (People's Republic of China), and Sinaloa (Mexico).
