Introduction: The Subsidies Are Gone. Now What?
From January to March 2026, the Japanese government ran another round of utility subsidies - up to ¥4.5 per kWh for electricity and ¥18 per cubic meter for city gas. For a family of four, that was roughly ¥1,800-2,500 off per month, automatically.
It ended in March.
If you haven't made any structural changes, expect your April bill to spike. This guide covers what you can actually do about it - permanently.
1. First: How Does Your Bill Compare?
Before optimizing, know where you stand. Average monthly electricity costs in Japan (2025 data):
| Household size | Monthly average | Annual total |
|---|---|---|
| Single | ¥7,337 | ~¥88,000 |
| Couple | ¥12,144 | ~¥145,000 |
| Family of 3 | ¥13,915 | ~¥167,000 |
| Family of 4 | ¥13,928 | ~¥167,000 |
| Family of 5+ | ¥15,665 | ~¥188,000 |
If you're above average, there's real room to cut.
2. The Biggest Win: Switch Your Electricity Plan
This is a one-time action with months or years of ongoing effect.
Check Your Amperage Contract
Most Japanese electricity plans calculate the base fee by contracted amperage. If you're over-contracted, you're paying a useless base fee every month.
| Household size | Recommended amperage |
|---|---|
| Single | 20A-30A |
| Couple | 30A-40A |
| Family of 3-4 | 40A-50A |
| 5+ people | 60A+ |
⚠️ Renters need to check with the landlord/management company before changing.
Switch Providers (The Highest-Impact Move)
Since Japan's electricity deregulation, consumers can freely choose their provider and plan. Broadly:
- High-usage households: Look for plans with lower second/third-tier unit prices, or flat-rate plans
- Low-usage households: Plans with lower first-tier unit prices
- Using gas and/or fiber too?: Bundled discount packages can reduce your total utilities cost
Use enechange.jp or similar comparison sites - enter your postal code and monthly usage to see projected savings immediately.
ℹ️ April is the ideal time to switch. Switching during the subsidy period had complications. Now that it's over, it's the clean window to evaluate your options.
3. Appliance-by-Appliance Power Saving
Focus on the biggest consumers first - that's where the marginal gains are highest.
Air Conditioner (Biggest Power Draw)
- Filter cleaning: A dirty filter reduces efficiency 15-25%. Clean it once a month - takes 10 minutes.
- Temperature settings: 20°C in winter, 28°C in summer
- Curtains: Close them while using A/C to prevent heat loss or gain
Refrigerator (Runs 24/7)
- Temperature setting: Dial down to "weak" or "medium" in winter
- Wall clearance: Keep at least 5cm from the wall for heat dissipation
- Don't overfill: Overpacking blocks cold air circulation
Standby Power (The Invisible Drain)
Japanese households reportedly lose ¥5,000-10,000/year to standby power:
- Use switched power strips and cut power to idle electronics
- Unplug devices during extended non-use (excluding always-on devices like routers)
Washing Machine / Dishwasher
If your plan has off-peak discounts (typically late night to early morning), schedule these appliances for those hours. Small habit, cumulative savings.
4. Gas Saving Tips
| Situation | Tip |
|---|---|
| Bathing | Have family members bathe consecutively to avoid reheating; use insulation sheets for the tub |
| Cooking | Keep lids on pots while boiling; match pot size to burner size |
| Heating | Combine gas heater with electric alternatives to reduce total gas usage |
5. Long-Term Investments Worth Considering
One-time costs that pay off over years:
| Action | Expected annual saving | Difficulty |
|---|---|---|
| Switch all lighting to LED | ¥2,000-5,000 | Easy (do it now) |
| Replace 10+ year-old refrigerator | ¥5,000-15,000 | Medium |
| Replace 10+ year-old A/C | ¥10,000+ | Medium |
| Solar panels + home battery | Large long-term savings | High (requires careful ROI calculation) |
ℹ️ Subsidies for energy-efficient appliances are sometimes available from local governments and METI. Check before purchasing.
6. Action Checklist: Start Today
- [ ] Pull your last 3 months' electric bills; compare to household average
- [ ] Run a comparison simulation on enechange.jp
- [ ] Verify whether your amperage contract matches actual usage
- [ ] Clean the A/C filter (10 minutes, immediate efficiency gains)
- [ ] Adjust refrigerator to "medium/weak" for the season
- [ ] Buy one switched power strip; start with the TV area
Conclusion: Plans and Habits Outlast Any Subsidy
Government subsidies are temporary. A well-chosen electricity plan and a few consistent habits are permanent.
Utility bills are a fixed recurring cost - every month, for years. A one-time effort to optimize your setup translates into ongoing savings with zero additional work.
With the subsidies now ended, April 2026 is exactly the right moment to make the switch.
