Japan's average power prices surged by over 25% week-over-week to reach 31.15 yen per kilowatt-hour. Bloomberg reported that Asian spot LNG prices hit a four-year high of $29.30 per MMBtu, the highest level since December 2022, driven by shipping risks in the Strait of Hormuz and intensifying competition with Europe for winter supplies.

Japanese utilities are facing additional pressure from thermal coal supply constraints out of Indonesia, which have tightened availability despite a shift toward coal-fired generation. These cost increases coincide with scheduled maintenance at several power-generating facilities ahead of the winter season, further impacting nationwide electricity rates.

Market attention turns to Japan's annual Inflation Rate data scheduled for release on October 22, 2026, with forecasts expecting a rise to 2.3% from the previous 1.9% as energy costs continue to influence broader economic indicators.
