J-Spirit

The J-Spirit (Jスピリット) is Kamen Rider J's transformation belt. It takes the form of a rhinestone belt buckle placed on Kouji's waist upon his transformation and revived by the Earth Spirits.

It is powered by a sacred crystal gem in its center, given to Kouji by the female Earth Spirit. This gem channels the holy J Power energy from the life force and spiritual energy of the planet Earth and its life forms. By channeling J Power, Kouji can transform into his Rider form and by drawing an even larger amount of J Power, can change into his Jumbo Formation giant form. Kouji can also use J Power from his belt to transform his motorcycle into the J-Crosser.
