This study analyzes gas prices, costs, and expenditures in Japan from a spatial perspective. The main findings are as follows: (1) Gas prices, costs, and expenditures exhibit spatially dependent patterns throughout Japan and are related to the service area locations of the gas distributors. (2) Regional conditions, including weather, production shipment, and availability and method of procuring domestic natural gas are the main determinants influencing gas prices and cost levels in Japan. These findings indicate that the Japanese government pays special attention to geographical perspectives in dealing with gas policies.
