Final answer:
In Japanese culture, omikuji are random fortunes found at Shinto shrines and temples, similar to the question's mention of preprinted slips of paper. These practices are not exclusively tied to Shinto but also to Buddhist influences, reflecting a long history of printed charms in Japan.
Step-by-step explanation:
Fortunes on preprinted slips of paper are a form of divination but they are not specifically referenced in Shinto beliefs or practices. However, in Japanese culture, which has been influenced by Shintoism, a similar practice involves omikuji, which are random fortunes written on strips of paper at Shinto shrines and temples.
While omikuji are more closely associated with both Shinto and Buddhist practices, the concept of printed fortunes pre-dates these and can be traced back to the early methods of printing in Japan. For instance, during the Nara period, Empress Shōtoku ordered the distribution of printed charms contained within miniature pagodas to thank Buddhist deities.
It is important to note that Shintoism predominantly recognizes the existence of kami, which are spirits that reside in natural elements such as rocks, trees, and places of significance.
