was a Japanese video game developer, best known for having created the Konami Code, a cheat code used in numerous video games typically granting the player extra lives or other benefits, and which has become often used as an Easter egg in popular culture. Career Hashimoto joined Konami along with several other recent college graduates in 1981. At the time, Konami was focused on coin-operated (coin-op) products such as medal games, and Hashimoto started by helping to develop the circuit boards for these games. Konami expanded over the next few years into arcade games with successful games like Scramble and Super Cobra, and later into bringing these games into versions for the Nintendo Entertainment System (NES). According to Hashimoto, the company's focus at the time still remained the coin-op machines, with experienced staff assigned to that area of the business.

Once the Super Nintendo Entertainment System (SNES) had arrived in 1990, Konami had brought in experienced video game developers and helped establish more rigor to the development process. One of the first NES games Hashimoto worked on was the conversion of Track & Field, a project that took six months between himself and another programmer. He later came back to the game to help design a special controller to use for the game as players reported it painful to use the standard NES controller.

Other games Hashimoto had developed at Konami included The Goonies for NES, and The Legend of the Mystical Ninja. Hashimoto continued to work at Konami through the rest of his life and has credits on at least nine games. Among other titles he worked on included the International Superstar Soccer series.
