Electricity & Gas Point-Earning: Split the One-Time Reward From the Monthly Bill Difference

Split the One-Time High-Value Reward From the Ongoing Monthly Bill Difference

With electricity and gas deregulation in Japan, you can now choose your provider freely, regardless of region. Electricity/gas point-earning, alongside budget SIMs, is a deal that pays off twice. The first layer is a high-value reward worth ¥3,000–15,000 in one shot for routing your switch to a new electricity/gas provider through a point site. The second is the fixed-cost saving as the plan itself gets cheaper and ecosystem points keep accruing on your monthly bill. The first is a one-time bonus at switch time; the second keeps working every month you stay. They're completely different in nature.

Don't lump them together: "grab the high-value reward in full at switch time, then keep using the cheaper plan" — frame it that way, and the bigger your household's usage, the larger the yearly difference. But high-value offers have conditions, and applying alone doesn't lock them in. On top of that, some plans (like market-linked ones) have prices that fluctuate, so choosing on reward size alone is a no-go. This article organizes electricity/gas point-earning around "split the high-value reward from the fixed-cost saving," "check the offer and cancellation terms," and "pick a plan that fits your ecosystem and usage." See also the fixed-cost cutting guide and the ecosystem comparison guide.

Breakdown of what you gain from switching

What you gain from switching electricity/gas falls into three: "the high-value routing reward," "monthly bill savings," and "earning ecosystem points." Getting a one-time bonus and an ongoing source of savings and points at once is exactly why this deal is so cost-effective.

Think of the "one-time high reward" and "monthly bill difference" separately

The single most important thing in electricity/gas point-earning is separating these two by nature. The high-value reward is a bonus you can take only once, at switch time. The bill difference keeps working every month for as long as you stay. Conflate them and you slide into the inefficiency of "switching constantly for the rewards."

• Take the high-value reward in full at switch time: It's a one-time bonus, so once you decide to switch, route through the best-condition site and don't leave any on the table. An electricity+gas bundle can earn an add-on too.
• The bill difference compounds "the longer you use it": The gap in monthly base and usage rates matters more the larger your household's usage. Over the long run, a bill that keeps dropping beats a one-off reward.
• Switching constantly for rewards backfires: Short-term cancellations fail the conditions, so the reward easily drops to zero, and plans with a lock-in may charge a cancellation fee. As a rule, switch once to a plan you can keep using.
• Matched to your ecosystem, your bill becomes a point source: With a company that fits your ecosystem, your monthly electricity/gas bill itself becomes a source of ecosystem points. Ecosystem comparison guide.

Check the plan's substance and choose accordingly

Choose a company on reward amount alone and the plan's substance may not suit you, leaving you worse off. Precisely because it's something you use every month, pick it by how the plan works and your own usage and home setup.

Step-by-step: making the switch

1. ① Narrow to a plan that fits your ecosystem and usageBeyond reward amount, pick a plan you can keep using by fixed-rate vs. market-linked, lock-in, ecosystem fit, and home setup. Ecosystem comparison guide.
2. ② Compare amounts and conditions on a point siteCheck each company's electricity/gas offer amount and conditions (supply start, usage period) on Pointnavi. Gauge whether you can meet them.
3. ③ Apply via the best-condition siteHave your meter-reading slip (current contract info) on hand, click through the site, then apply online in about 10 minutes. Consider an electricity+gas bundle.
4. ④ Wait for the switch to completeNo construction needed; with a smart meter, no attendance either. It switches over in 1–2 months. The blackout risk is unchanged.
5. ⑤ Set up ecosystem points ＋ card paymentPay the bill with your ecosystem's credit card to double-dip on payment too. Consolidate after payout. Double-dipping guide · expiry-prevention guide.

Common mistakes and how to avoid them

• Not checking conditions and settling for just applying: High-value offers usually require supply start plus a set usage period, not just applying. Cancel before you meet it and the reward is zero. Check the conditions before applying.
• Signing up without knowing it's market-linked: A market-linked plan can become pricey during spikes. Always confirm fixed-rate vs. market-linked before choosing.
• Repeating short-term cancellations for rewards: Plans with a lock-in may charge a cancellation fee. As a rule, switch once to a plan you can keep using.
• Not fitting your home setup: The best plan differs for all-electric vs. electricity+gas. Simulate by usage and home setup before choosing.
• Forgetting to route: Go straight to the application form and routing cashback is zero. Re-click the point site right before applying. Pointnavi.

Prep to have ready before switching

• Check offer and cancellation terms: Know the conditions that lock in the reward (supply start, usage period) and whether there's a contract lock-in or cancellation fee — before applying.
• Meter-reading slip (current contract info): Have on hand a meter slip or your account page showing your current contract info. It makes the application smooth.
• Plan simulation: Check fixed-rate vs. market-linked and whether it fits your usage and home setup with each company's simulation.
• Compare on Pointnavi before routing: Compare candidate companies' amounts and conditions on Pointnavi in advance, and pick the best-condition route.
• Ecosystem card and a point consolidation spot: Set up paying the bill with your ecosystem's card to take payment cashback too, and decide where you'll consolidate points.
