is a traditional Shinto system of divination. Practitioners attempt to foresee future events by interpreting the pattern of cracks made by heating the shoulder-blade of a stag. The practice is thought to predate the introduction of divination by tortoiseshell, which was imported from China; archaeological evidence suggests it originated as early as the JÃ Âmon period.
The kami most commonly associated with Futomani is , also-known-as , a special Kami of divination.
Futomani is still practiced at the Shinto shrine on Mount Mitake as an annual event.
In aikido, futomani is considered an important adjunct to kotodama practice.
