- Because your current provider is set to "Other / not sure", this estimate is based on 中国電力 "シンプルコース". If your actual contract differs, the savings may be higher or lower. Entering your current bill from "Compare more accurately" gives a result closer to your real usage.
- Your 12-month electricity usage is estimated from the information you entered and the climate of your area, and the electricity cost is calculated for the 12 months starting from the current month.
- The fuel cost adjustment and power procurement cost adjustment are calculated by applying the unit price for October 2026 across all 12 months. Unit prices are updated to the following month's rate on the last day of each month (or the next business day if it falls on a holiday). The renewable energy levy uses the latest unit price, which is updated every May.
- The way capacity contributions are reflected, and what they are called, differs by provider. This service always displays them as "capacity contribution equivalent". For plans where the capacity contribution is included in the fuel cost adjustment or power procurement cost adjustment, it is shown together under "Fuel cost adjustment, etc.".
- The basic / minimum charge, energy charge, fuel cost adjustment and related charges, capacity contribution equivalent, and renewable energy levy are each totalled over 12 months, rounded down to the nearest yen, and those totals form the annual electricity cost.
- Government subsidies such as electricity cost relief programmes are not included in the results.
- For areas where the remote-island universal service adjustment rate applies, it is included in the results.
- For plans with no amperage (contracted capacity) bands, the basic / minimum charge is calculated as a fixed amount regardless of the amperage you selected.
- All savings and amounts shown are estimates and do not guarantee your actual bill or savings.
- Whether your current plan has a cancellation or early termination fee, and how much it is, depends on when you signed up and how long you have been contracted. Please check with your current provider before switching.

- Because your current provider is set to "Other / not sure", this estimate is based on 中国電力 "シンプルコース". If your actual contract differs, the savings may be higher or lower. Entering your current bill from "Compare more accurately" gives a result closer to your real usage.
- Your 12-month electricity usage is estimated from the information you entered and the climate of your area, and the electricity cost is calculated for the 12 months starting from the current month.
- The fuel cost adjustment and power procurement cost adjustment are calculated by applying the unit price for October 2026 across all 12 months. Unit prices are updated to the following month's rate on the last day of each month (or the next business day if it falls on a holiday). The renewable energy levy uses the latest unit price, which is updated every May.
- The way capacity contributions are reflected, and what they are called, differs by provider. This service always displays them as "capacity contribution equivalent". For plans where the capacity contribution is included in the fuel cost adjustment or power procurement cost adjustment, it is shown together under "Fuel cost adjustment, etc.".
- The basic / minimum charge, energy charge, fuel cost adjustment and related charges, capacity contribution equivalent, and renewable energy levy are each totalled over 12 months, rounded down to the nearest yen, and those totals form the annual electricity cost.
- The savings shown for this plan are the switching savings from the rate comparison above plus a site-exclusive friend referral discount of ¥8,000. The total in the rate details table is shown after deducting this discount.
- Government subsidies such as electricity cost relief programmes are not included in the results.
- For areas where the remote-island universal service adjustment rate applies, it is included in the results.
- For plans whose basic charge is linked to contracted capacity (kVA / kW), the 30A you selected is treated as equivalent to a contracted capacity of 3 kVA. Actual contracted capacity and contracted power are determined by your usage and equipment, so the calculated basic charge may differ from the actual one.
- For plans with no amperage (contracted capacity) bands, the basic / minimum charge is calculated as a fixed amount regardless of the amperage you selected.
- All savings and amounts shown are estimates and do not guarantee your actual bill or savings.
