Regarding the occurrence of JRPG's unique game design and the charactaristics of it, the discussion analyzed the game stories of three RPGs released from 1993 to 1994 (Shin Momotaro Densetsu, FF6, EarthBound) and their rival characters with uniqueness. From the analysis, a hypothetical construction was considered. In conclusion, it can be argued that the characteristic property of JRPG is game design, in which game’s properties depends on game scenarios, and that it was already sprouting around the fourth generation game machine, which had great restrictions on movies etc.
