Tokyo; bringing the people of both sides together as one in a united Tokyo. Development Development of Shin Megami Tensei IV began around August 2009, after development had finished on Shin Megami Tensei: Strange Journey for the Nintendo DS, and lasted for three and a half years. After listening to fan demand, Atlus decided to make a fourth numbered entry in the Shin Megami Tensei subseries, something not seen in Japan since the release of Shin Megami Tensei III: Nocturne in 2003. The reason for the ten-year gap between III and IV was that the company had made other successful titles, and had not had the time to develop Shin Megami Tensei IV as well.

Kazuma Kaneko, a character designer and scenario writer for the series, came up with the original scenario. He came up with the original concept for the medieval Mikado and modern-day Tokyo: the main reason for this was to present a contrast of values between the demon-hunting inhabitants of Mikado and the people of Tokyo, who live under the
