In 2023, Japan imported natural gas in gaseous state at a level which stood at an unspecified baseline. Forecast data for 2024 to 2028 shows a consistent year-on-year decrease in imports, with a compound annual growth rate of decline over the five-year period. Specifically, from 2024 at 30.33 thousand kilograms, there's a projected 3.46% annual decline in import volumes through 2028 at 26.25 thousand kilograms.

Future trends to watch include:

Increased domestic alternative energy production and drive for cleaner energy sources.
Potential shifts in international gas supply and pricing dynamics due to geopolitical factors.
Japan's policy changes towards renewable energy investments and infrastructure improvements.
