This study analyzed photos posted on Instagram by 5 American and 5 Japanese design students over 2 months to explore cultural tendencies. Individualist American culture emphasizes personal achievement and competition, while collectivist Japanese culture prioritizes family and group goals. The American students' photos primarily featured selfies and photos with others, fitting individualist norms of self-promotion. Conversely, the Japanese students rarely posted photos of themselves and more often featured surroundings, aligning with collectivist values of subtlety and close relationships over virtual connections. In conclusion, the types of photos uploaded to Instagram reflected the different cultural influences of individualism in the US versus collectivism in Japan.
