The layout of Shibuya was duplicated for the game, retaining the real-world landmarks while rebranding the names of stores and buildings for copyright reasons; for example, the 109 Building was renamed to be the "104 Building", while one of the busiest Starbucks, adjacent to the scramble crossing, was renamed "Outback Cafe". The success of the game has led to fans going on tours of the district to match physical locations in Shibuya with those in the game. The selection of Shibuya led to the incorporation of much of the game's other features, including food, clothing, and cell phone usage. The team initially thought of the idea of using graffiti around Shibuya as the source of the player's power in the game but had difficulty representing it; this led to the creation of the psych pins used in the game.
