Paralympic games, whether citizens will watch the Paralympic games at sport facilities remains to be determined. Increasing the number of spectators and supporters is critical to attract new sponsors and gain additional revenue. The objectives of this study are twofold. First, it reveals spectators' demographic attributes and, second, using the Motivational Scale for Disability Sport Consumption (MSDSC), it tests for moderating effects on future intentions to spectate the 2020 Tokyo Olympic Paralympic Games. Researchers distributed questionnaires to spectators who attended the 46th Japan Wheelchair Basketball Championship Emperor's Cup on May 19, 2018 (499 valid samples) and May 20, 2018 (487 valid samples). A confirmatory factor analysis (CFA) eliminated two items from the model. Next, a multiple regression analysis is conducted to test the relationship between spectator motivation and intention to attend a mega sporting event. The results highlight that there is a considerable difference in the effect of the three moderator variables. In conclusion, it is imperative for practitioners to inform spectators about the uniqueness and singularity of wheelchair basketball.
