NJPW Strong Spirits (2021) was a mobile card-collection and management game published by Bushiroad. Players collected digital cards of NJPW stars like Okada, Tanahashi, and Naito, training and evolving them for use in simulated matches. It tied into Bushiroad’s expertise in card-based mobile titles.

While not a traditional wrestling sim, it appealed to collectors and NJPW fans. It combined elements of training, gacha mechanics, and story events that reflected real-world rivalries. The game was eventually shut down but is remembered for spotlighting NJPW’s modern era in mobile gaming.
