Switching Power & Gas × Point Activity 2026 — Lower Bills + Offer + Point Linkage

Switching Electricity & Gas: A Permanent Cut to Fixed Costs

Reviewing your utility bills is one of the most powerful ways to reduce living costs — and unlike coupons or limited-time sales, once you switch, the savings continue every single month without any further action. On top of that, the switching application itself qualifies as a "reward offer" on point sites, so you earn a one-time bonus on top of your ongoing savings. And by choosing a provider linked to a point economy (like Rakuten Denki for Rakuten points), your monthly electricity payment automatically earns points.

This guide covers: the core value of bill reduction · how switching offers work and what conditions to watch · economy point linkages · why results vary by region and usage · step-by-step switching process and pitfalls to avoid. Because rates, reward amounts, and campaign conditions change by season and region, always check the latest details on each official site and Pointnavi.

The Basics: How Deregulation Works and Why Your Supply Won't Be Interrupted

Since Japan's full retail electricity deregulation in 2016 and city gas deregulation in 2017, households can freely choose their electricity and gas providers. A common concern is: "Will switching to a new provider cause more blackouts?" The short answer: no, your power quality and blackout risk stay exactly the same.

Here's why: the physical grid that delivers electricity to your home — the poles and wires — continues to be maintained by the regional major utility. New electricity providers simply use that shared infrastructure. The same applies to gas: the pipelines remain under the incumbent gas company's management. What changes is only the rate plan and who you pay. Even if a new provider goes bankrupt or exits the market, supply continues under Japan's last-resort supply guarantee system — you won't be left without power or gas. Knowing this removes most of the psychological barrier to switching.

Three Separate Benefits — Understand Each Independently

The gains from switching electricity and gas come from three distinct sources, each with a different nature. Understanding them separately is key.

These three are completely independent. Benefit ① has more impact for high-usage households; low-usage households may see smaller differences. Benefit ② is a one-time income separate from ongoing bill savings. Benefit ③ only helps if you actually use that economy's services. Decide which pillar matters most to you before choosing a provider.

Why Results Vary: Region, Usage, and Household Type

Switching isn't equally beneficial for everyone. Whether your bills actually drop — and by how much — depends on several factors:

• Region (electricity service area): New providers don't serve every area equally. Some regions have fewer competitors, limiting your choices. The regulated tariff baseline also differs by region, affecting how much room there is for savings.
• Monthly usage (kWh): Higher usage generally means a larger absolute saving when the per-unit rate drops. Lower-usage households may see smaller differences. Always check your monthly kWh on your electricity bill before comparing plans.
• Household type and home setup: All-electric homes, city gas homes, and propane (LP gas) homes each have different applicable providers and plans. Apartments vs. houses, rentals vs. owned properties — all affect whether switching is possible and how the process works.
• Your current plan: If you're already on a discounted plan or have a bundle deal with internet or mobile services, simply switching may not be the right move. First review all the discounts you currently receive.

An angle that’s especially easy to overlook is how to judge things for "single-person households with low usage." If you live alone and use little each month, the absolute amount you can save tends to be small even when the unit price drops, so looking at the bill alone may make switching feel pointless. Even then, combining the pillars beyond pure bill reduction — zero base-fee plans, economic-zone point linkage, and the one-time switching offer at sign-up — can still produce a worthwhile benefit. Start by checking your monthly kWh on your meter-reading slip, and review your fixed costs as a whole alongside your phone bill; our budget SIM comparison is a useful companion for seeing which pillar to chase savings from.

How Switching Offers Work — and How to Read the Conditions

Electricity and gas switching applications are a popular category of point site offers. Compared to simpler offers, however, they tend to have more complex eligibility conditions and longer reward timelines. It's not enough to just click through a point site — you need to understand exactly when points are confirmed.

• At application vs. after first billing: Most electricity and gas offers don't confirm points at the moment of application. Points are typically confirmed after the switch is complete and the first bill has been issued — which can take several weeks to a month.
• Region and plan restrictions: Even with the same provider, certain regions or plans may be excluded from the offer. Always check the "eligible regions and plans" section on the offer detail page before applying.
• Returning customers and re-applications: Offers restricted to "new customers only" won't apply if you've previously had a contract with the same provider. Check the conditions carefully.
• Cancellations void the reward: If you cancel mid-process, point rewards are typically not paid out.

Reward amounts and conditions vary by provider and time period, and occasional bonus campaigns may apply. Check current offer details on Pointnavi for the most accurate information.

Economy Point Linkage: Your Monthly Bill Becomes Automatic Point-Earning

While bill savings and switching rewards both have one-time or variable aspects, economy point linkage is a benefit that continues every month. Choosing a new electricity provider that matches your main point economy turns your utility bill into a steady point earner.

The biggest advantage of economy point linkage is automation — once set up, points accumulate every month without any further action. However, point eligibility conditions, payment method requirements, and caps differ by provider. For example, some providers only award points for credit card payments, not bank transfers. Always check the official site before applying.

How to Switch: Step-by-Step (No Construction, No Site Visit)

Many people assume switching electricity or gas requires tradespeople or complicated paperwork. In most cases, the process requires no site visit or construction — it's similar in effort to canceling and restarting a subscription. If your home already has a smart meter, the switch typically completes entirely remotely.

1. ① Check your current usage on your meter slipNote your monthly kWh and current bill amount. Also identify your electricity service area, whether you use city gas or propane, and any cancellation terms on your current contract.
2. ② Estimate costs with a comparison toolEnter your address and usage volume to see estimated costs from new providers. Compare several options and determine whether switching makes financial sense for you.
3. ③ Check for point offers on Pointnavi and click throughBefore applying, visit Pointnavi to confirm whether your target provider has an active offer, and check the reward amount and conditions. If an offer exists, click through the point site first — this is a prerequisite for earning the reward.
4. ④ Complete the application formEnter your address, current provider name, customer number (found on your meter slip), and payment method. In most cases, you don't need to contact your current provider to cancel — the new provider handles this.
5. ⑤ Confirm the switch and check your first billSwitching typically takes several weeks to a month. When your first bill arrives, verify the new plan is correctly applied. Point offer rewards are usually confirmed around this time.
6. ⑥ Confirm your economy point linkage settingIf you're using point linkage, check the official app or your account page to confirm the linkage is active.

Important Warnings and Common Pitfalls

• Check for cancellation fees: Some new providers have cancellation fees on specific plans or contract terms. Review the contract conditions before signing up, including whether fuel cost adjustments have a cap.
• Market-linked plans carry rate spike risk: Some new providers offer plans where your rate is tied directly to wholesale electricity market prices. When energy markets spike, these plans can end up costing more than regulated tariffs from major utilities. Always understand the pricing structure before applying.
• City gas switching doesn't apply to propane (LP gas): New gas plans under deregulation apply only to city gas (pipeline gas) customers. If you use propane (LPG), you'll need to negotiate separately with your LP gas company. Check your gas bill to confirm which type you use.
• Rental restrictions: If you contract directly with the electricity company yourself, you can switch even as a renter. However, if your building has a bulk electricity contract managed by the property management company ("bulk reception"), individual switching may not be possible. Check the name on your meter slip.
• Always click through the point site first: When applying for a point offer, you must click through the point site before opening the provider's application form. If you navigate to the official site first and then try to add the point link afterward, the tracking often won't work and you'll miss the reward.
• Don't lose bundle discounts: If your current electricity or gas provider gives you a discount bundled with internet or mobile services, switching electricity alone could eliminate that bundle discount, leaving you worse off overall. Take stock of all the discounts you currently receive before making a change.

Learn in advance how to tell whether a rental uses "bulk power contracting" (ikkatsu juden). If the name on your meter-reading slip or bill is your own (the resident), you can most likely switch as an individual; if the name is the management company or landlord, or a single bill covers the whole building, that’s a sign of bulk contracting where individuals cannot switch. When unsure, the surest move is to ask the management company directly whether your contract lets you choose your own power company. If you’re switching around a move, checking it together with our rental initial-cost guide, which sorts out housing-related procedures in one place, helps you avoid oversights around contracts and account names.

Lower Bills vs. More Points: Clarifying Your Priorities

When comparing new electricity and gas providers, most people focus only on which is cheapest. But your real "benefit" isn't determined by price alone — point linkage, offer rewards, plan stability, and customer support all factor in. Decide what you're optimizing for before comparing.

For current offer details and rate comparisons, always check Pointnavi for the latest information.

Common Mistakes and How to Avoid Them

• Applying without clicking through the point site first: The most common mistake. Before opening any application form, go to Pointnavi, find the offer, click through to the provider's site, and then apply — in that exact order. Never open the official site directly first.
• Underestimating market-linked plan risk: "It's cheap right now" is not sufficient reason to choose a market-linked plan. When energy markets spike, bills can soar unexpectedly. Always understand the pricing mechanism.
• Losing bundle discounts without realizing: Switching electricity or gas can eliminate discount bundles with internet or mobile plans, leaving you worse off overall. List all current discounts before making any changes.
• Trying to switch when you're on propane gas: City gas deregulation doesn't apply to propane/LPG customers. Confirm your gas type from your gas bill before researching options.
• Not checking whether points were actually awarded: After switching, check your point history on the point site one to two months later. If there's a problem, you need to catch it before it's too late to follow up.

What these failures share is "skipping the one bit of legwork before applying." Check your current situation on the meter-reading slip, estimate with a simulator, and only then go through a point site after reviewing the offer and its payout conditions — keep that order and you can prevent almost every problem in advance. Switching is a long-running move that keeps paying off every month once done, so spending time on that first check is well worth it.

Mini Glossary — Key Terms for Electricity & Gas Switching

Understanding how the system and pricing work makes a real difference to your outcome. Here are the key terms, each paired with what to watch out for when making decisions.

These are the foundational concepts for understanding electricity and gas switching. The core value is ongoing monthly savings that continue after a single switch — on top of which you layer a one-time switching offer reward and monthly economy points for a triple benefit. The grid is shared and quality is unchanged. Check your meter slip for usage, contract holder, and cancellation terms. Watch for market-linked price spike risk and the potential loss of bundle discounts. Always click through the point site before applying, and choose a provider based on your own priorities — bill reduction, economy points, or switching offer.
