Japon : prix de l’électricité

Japan publishes no single national price per kWh, so this is the regulated Meter-Rate Lighting B tariff of TEPCO Energy Partner, the largest utility, which serves Tokyo and the surrounding Kanto region. TEPCO's model household (30 amperes, 260 kWh a month) reaches the second block, where each extra kWh costs ¥36.45 including 10% consumption tax. The figure leaves out the basic charge (¥1,176.18 a month at 30 A), the monthly fuel cost adjustment (minus ¥5.33 per kWh for November 2026) and the renewable energy surcharge (¥4.18 per kWh); with all of these the model household's November bill is ¥9,561, about ¥36.8 per kWh. Other regional utilities and competing retailers charge different rates, so the price on your own bill is the most accurate.

TEPCO charges each block of a month's use at its own rate: the first 120 kWh at the first rate, the next 180 kWh at the second and everything above 300 kWh at the third, all including 10% consumption tax. Every bill also carries a basic charge set by the contracted amperage (¥392.06 a month at 10 A up to ¥2,352.36 at 60 A), the fuel cost adjustment, which changes every month (minus ¥5.33 per kWh for November 2026), and the renewable energy surcharge of ¥4.18 per kWh on bills from May 2026 to April 2027. A government subsidy lowers low-voltage bills by ¥1.0 per kWh for electricity used in December 2026 and by ¥4.5 per kWh for January and February 2027.
