This study examines how seating position affects immersive perception during live Olympic events in a planetarium. Advances in digital domes have broadened planetarium use beyond astronomy education, enabling large-scale cultural applications such as sports screenings. As part of a broader project investigating dome-based live sports viewing, this study reports a preliminary survey conducted during the Tokyo 2020 1st Anniversary Event at the Fuchu Municipal Museum Kyodonomori Planetarium. The survey employed the Semantic Differential method to assess perceptual impressions across four seating areas. Analysis of 53 valid responses indicated that participants found the experience powerful and enjoyable, although the limited 4K resolution caused noticeable blurriness. Exploratory seating tendencies showed that the rearmost area received the most positive evaluations, while lateral distortion had minimal impact. These findings suggest that planetariums can serve as immersive cultural venues with potential applications in virtual tourism.
