Introduction
If your May electricity bill felt higher than usual, you’re not imagining things. Two changes hit at the same time this month.
First, the government’s electricity and gas subsidy program ended after March usage. Second, the renewable energy surcharge (saisei kanou energy hatsudenso sokushin fukakin) was raised to a record-high 4.18 yen/kWh. Together, these changes mean most households are paying around 1,000 to 1,500 yen more per month.
This article breaks down what changed, how it affects your household budget, and five things you can do right now to keep costs down.
TL;DR
- The government’s electricity and gas subsidy ended after March 2026 usage (reflected in May bills)
- The renewable energy surcharge increased from 3.98 to 4.18 yen/kWh starting May 2026
- Solo households: roughly 300-500 yen/month increase
- Family households: roughly 800-1,000 yen/month increase
- Replacing old appliances and reviewing your contract amperage can meaningfully lower your bill

What Changed? Two Factors Behind the Increase
Factor 1: Government Subsidy Ended
The government had been offering electricity and gas bill subsidies as part of its response to rising energy costs. The most recent round covered January to March 2026 usage, providing a discount of 1.5 yen/kWh on electricity and 0.5 yen/m3 on city gas.
From April usage (billed in May), the subsidy is gone.

For a standard household using 260 kWh per month, the subsidy removal alone means about 390 yen more on electricity, plus 100-200 yen more on gas.
Factor 2: Renewable Energy Surcharge Raised
The renewable energy surcharge (saiene fukakin) is a fee that all electricity users in Japan pay to fund the expansion of renewable energy sources like solar and wind power. It’s automatically included in your electricity bill.
Starting May 2026, the rate was raised from 3.98 to 4.18 yen/kWh, the highest since the system started.

The renewable energy surcharge is the same nationwide, regardless of which electricity provider you use. Switching to a different provider won’t reduce this specific charge.
Impact by Household Type
| Household | Monthly Usage | Subsidy End Impact | Surcharge Impact | Total Increase/Month |
|---|---|---|---|---|
| Living alone | ~200 kWh | ~300 yen | ~40 yen | ~340 yen |
| Couple | ~300 kWh | ~450 yen | ~60 yen | ~510 yen |
| Family (3-4 people) | ~400 kWh | ~600 yen | ~80 yen | ~680 yen |
These figures cover electricity only. Adding the gas subsidy removal (100-200 yen/month) brings the total for families to around 800-1,000 yen/month. With summer air conditioning, the impact will be even larger.

Why Did the Subsidy End?
The electricity and gas subsidy was introduced in 2022 as an emergency measure when global energy prices surged. However, the cost to the government was significant, and as energy markets stabilized, the program was gradually scaled back.
The January-March 2026 round was a temporary revival to help with winter heating costs. No extension beyond March has been announced as of May 2026.
The subsidy has come back before after ending once. Keep an eye on METI announcements in case it’s revived again for summer.
5 Ways to Reduce Your Electricity Bill Now
1. Replace Old Appliances
Air conditioners and refrigerators that are more than 10 years old are significantly less energy-efficient than current models. Refrigerators, in particular, have seen major efficiency gains, and swapping in a newer model alone can meaningfully cut your annual electricity bill. Rather than waiting for an old appliance to break, it’s worth planning ahead and watching for subsidy programs or seasonal sales. For tips on finding affordable options, see our guide to furniture and appliance stores in Japan.
2. Review Your Contract Amperage
If you live alone, 30A is usually enough. If you’re on a 40A or 50A contract, you may be paying 300-600 yen extra per month just in base fees.
3. Adjust Air Conditioning Temperature
Set your AC to 28°C in summer and 20°C in winter. A 1-degree change can affect your electricity bill by about 10%.
4. Cut Standby Power
Unplug appliances you’re not using, especially TVs, microwaves, and PCs. Using a power strip with an on/off switch makes this easier.
5. Switch to LED Lighting
If you’re still using fluorescent lights, switching to LEDs can cut lighting electricity costs by about 50%.
FAQ
Q. What is the renewable energy surcharge? Do I have to pay it?
A. It’s a fee that funds renewable energy expansion in Japan. All electricity users pay it automatically. There’s no way to opt out.
Q. Will switching providers reduce the renewable energy surcharge?
A. No. The surcharge is the same nationwide. However, the base rate and per-kWh charges can be lower with a different provider.
Q. Will the subsidy come back?
A. Unknown at this point. The government has revived it before, so it’s worth watching for announcements.
Q. When should I consider replacing an old appliance?
A. Ten years is a common benchmark. Refrigerators, air conditioners, and washing machines have all improved significantly in energy efficiency over the past decade. Some municipalities offer subsidies for replacing old appliances with energy-efficient models, so check your local city or ward office website.
Q. Are gas bills going up too?
A. Yes. The gas subsidy also ended, adding about 100-200 yen/month. If you’re on propane gas (which is more expensive), moving to a city gas area could be worth considering.
Key Takeaways
- ✅ If you’re using a refrigerator or air conditioner more than 10 years old, start planning a replacement (prioritize the refrigerator)
- ✅ Begin with no-cost changes: review your contract amperage and adjust AC temperature settings
- ✅ Keep an eye on municipal energy-efficient appliance subsidies and METI announcements about any subsidy revival
This increase isn’t a one-off bump. It’s a structural shift driven by both the end of subsidies and a higher renewable energy surcharge. Rather than waiting until the bill arrives, it’s worth starting small adjustments now, before summer’s peak electricity demand hits, to soften the impact on your household budget.
