Setting up gas utilities when moving into a new home or apartment in Japan requires contacting the designated local provider assigned to the property, which can be identified through real estate agents or information stickers placed near gas meters. Customers typically submit an application online or via phone at least a couple of weeks before their scheduled move-in date, providing essential details such as their full address, personal name, contact information, and desired activation date. A critical requirement for establishing gas service in Japan is scheduling an in-person appointment with a certified technician who must visit the property to safely open the supply valve, test the gas lines, and check connected appliances. The resident must be present during this brief safety inspection before gas can flow.
