As the Catechism of the Catholic Church states in 2116 and 2117
2116 All forms of divination are to be rejected: recourse to Satan or demons, conjuring up the dead or other practices falsely supposed to “unveil” the future.48 Consulting horoscopes, astrology, palm reading, interpretation of omens and lots, the phenomena of clairvoyance, and recourse to mediums all conceal a desire for power over time, history, and, in the last analysis, other human beings, as well as a wish to conciliate hidden powers. They contradict the honor, respect, and loving fear that we owe to God alone.
Of course all of the things the Church mentions as things to avoid are present and even widespread here. Horoscopes are a big part of the morning news on several stations with their own short segment like the weather and traffic have. Fortune tellers such as palm readers set up a small chair and table on sidewalks in busy areas of Tokyo in the evening. At Shinto shrines and Buddhist temples people purchase fortunes called omikuji http://en.wikipedia.org/wiki/Omikuji
At temples and shrines people may also purchase charms or amulets called omamori http://en.wikipedia.org/wiki/Omamori
Children may play with the Japanese version of a ouija board which is called kokkuri san here. There also appears to be a movie with kokkuri san as the title. Much less common I would think but still exists is Japanese voodoo. This guy even managed to order a kit and took photos http://www.juergenspecht.com/truestories/?number=8&storypage=2
There is also a type of fortune telling based on blood type. One thing it does is try to put people into categories based on how their personality should be according to blood type. http://en.wikipedia.org/wiki/Japanese_blood_type_theory_of_personality
The main message I want to convey in this post is to be careful if you are a Catholic who values your faith. For example shopping at shrines and temples for little good luck charms or such trinkets as souvenirs isn’t a good idea. They are charms and as innocent as they seem don’t bother.
