At first, the promotion used a hyper realistic style, mixing wrestling with strong MMA influences. INSPIRE was portrayed as a "next generation" promotion where fighters from all backgrounds could come and test themselves. By 2008 that approach had been modified slightly, when it became clear that becoming too heavily MMA-influenced had led them to actually start competing with Japan's biggest Mixed Martial Arts promotion, the financially mighty Alpha-1. The promotion has now more clearly defined itself as part of the wrestling market.
