Japan imports nearly all of its natural gas as LNG. Prices are influenced by global LNG markets and can fluctuate significantly. The government encourages energy efficiency and has various subsidy programs for households.

Current Situation in Japan

After the 2011 earthquake, Japan increased LNG imports. Prices remain relatively high compared to the U.S., but efficiency standards and government rebates help offset costs.

LNG Spot Price and Electricity Bill Increase

Many Japanese consumers and businesses track the “LNG Spot Price” because electricity bills are directly tied to gas import costs.

Tokyo Gas Rates and City Gas

Tokyo Gas is the dominant utility. “City Gas” (Toshi Gasu) refers to grid-supplied natural gas, while many households still use LP gas (propane).

Liberalization and Calorific Value

The 2017 market liberalization (Jiyuka) allowed more switching, and many still search for “Calorific Value” to understand the heat density of their gas supply.
