Playing Pokémon go game can contribute to higher self-esteem of Japanese hikikomori players, leading to stronger family bond and friendship. Hikikomori are people with a severe social withdrawal, as a result of anxiety towards interaction with society and mistrust in themselves, and on contrary building self-confidence could be the key in their treatment (Forsberg, 2012). In Pokémon go players need to collect characters, called “pocket monsters” in order to obtain higher level in the game. According to Jones et. al. (2014), leveling up in video games is an accomplishment which enhances mental health of player and self-satisfaction and maintain tight family connection and friendship.
