In 1995, Mr. Ishihara established a game planning/producing company, Creatures Inc., and produced the videogame Pocket Monster Aka and Midori (Pokémon Red and Blue), the basis for future Pokémon products. Ultimately, he nurtured those popular characters into a global phenomenon that continues to this day. In 1998, he participated in founding the Pokémon Center Co., Ltd. (currently The Pokémon Company) where he assumed the post of president. Currently, he is involved in the Pokémon Trading Card Game, adapted from the Pokémon videogames, as well as management of the entire Pokémon brand,including the TV animation series and theatrical movies. He said in an interview that one of his of his biggest goals is making a game better than Mario. The idea of having two games come out at the same time (red and green, diamond and pearl), he says were not his idea but the idea of one of the heads of Nintendo. This great idea led to Pokemon making double the money they probably would have made.
