Forgot to Pay Electricity Bill in Japan? What to Know & Do

Forgot to pay your electricity bill? Or your water or gas bill? This article will guide you through the steps for how to get your electricity bill turned back on.

How electricity cutoff rules work in Japan

Japan’s electricity market is deregulated, which means rules and timelines can vary slightly depending on your electricity company and contract.

However, all major power companies in Japan follow a broadly similar pattern when your bill is unpaid:

• You’ll receive multiple reminders before any disconnection happens

• Late payment interest is typically 0.03% per day (around 10% annually)

• Power is usually cut off around 50 to 57 days after your meter reading date, if you do not pay

• Service is generally restored after payment is confirmed

This applies to major providers such as: TEPCO (Tokyo), KEPCO (Kansai), Chuden (Chubu), Kyuden (Kyushu), Tohoku Electric, Hokkaido Electric, Shikoku Electric, Chugoku Electric, Hokuriku Electric, and Okinawa Electric.

📝 Note: Exact timelines and processes may differ slightly by region and provider. Always refer to your utility company’s latest notice or customer center for your specific situation.

What to do if you've forgotten to pay an electricity bill

Fortunately, if you forget to pay an electricity bill in Japan, you won't lose electricity immediately. Often, you will receive a few new invoices and a reminder to pay by a specified date.

However, failing to pay your electricity bill after 50 to 57 will result in the utility company cutting off your power supply.

The easiest way to deal with an overdue payment is to take your new invoice and pay it by the appointed date. But suppose you can't make your payment because you lost your invoice?

In that case, you should call your electricity supplier's customer service hotline, and they will reissue a new payment voucher for you. 

Always remember to check the back of the invoice for accepted payment methods. Some convenience stores won't process bills past their due date, so you may have to go to the utility company to settle the amount.

🚨 Quick reference: critical information

Before power gets cut:

• ⏰ Grace Period: 50 to 57 days

• 📋 Action Required: Pay any outstanding invoices immediately

• 📞 Lost Invoice: Call customer service for reissue

After power gets cut:

• 🔌 Immediate Action: Contact utility company customer service

• 💰 Late Fees: 0.03% per day (10% annually)

• ⚡ Reconnection: 2-24 hours after payment (varies by company)

Payment timeline & consequences

Days from meter reading	What happens	What you should do
Day 30	Your payment deadline arrives	Pay by this due date
Day 40	Your electricity provider sends a reminder postcard	Pay right away to avoid a late fee
Day 50	You get a final notice with a set cutoff date	Contact the company or pay in full
Day 57	Power disconnection can happen	Call your provider and settle your bill

This timeline is a general guide. Your electricity board may set slightly different dates.

Weekend/Holiday Impact: Power cutoffs typically don't happen on weekends or national holidays, but payment processing may be delayed.

Your due date always sits 30 days after your meter reading date. Check your bill for your exact date.

This timeline can vary depending on your electricity provider. Contact customer service if a date on your bill looks different.

Step-by-step guide on what to do if you lose electricity

Here are some steps to take if you lose electricity because you forgot to pay your electricity bill.

Step 1. Locate customer support

Locate the call center or customer support page for the utility service provider that you are using. We provide a list of all the major electricity service providers in Japan further down in this article.

Step 2. Contact customer support

Contact your utilities' customer support immediately if you lose power after not paying your electricity bill.

Step 3. Settle your late fees.

The utility company's customer center will walk you through how to settle your late fees and restart your power supply. However, you may not receive power immediately after paying your bill. How long it takes depends on the power company and the situation.

The best way to prevent losing your power is to make sure you pay your bills on time. If you frequently forget to pay utility bills, consider switching payment methods to an automatic withdrawal billing system.

How much are late payment penalties?

Late account transfer payment on an electric bill can incur an interest rate of 0.03% per day (10% annually). 

Your bill also includes consumption tax on top of your electricity charge. This tax is already included in the total amount shown on your invoice.

For example, if the bill was ¥5000, and you pay it 30 days after the due date, the company may charge a late fee of ¥45. 

Although this is a small fee, you can ultimately lose your electricity if you continue to ignore paying your bill. 

How to pay your electricity bill online

You do not need to visit a convenience store to pay. Most electricity companies let you pay your electricity bill online.

Here is how to pay in a few simple steps.

• Find your customer number on your paper invoice

• Open your preferred payment method, such as a banking app or LINE Pay

• Scan the QR code printed on your invoice with your phone

• Confirm the amount and complete the payment

• Save your confirmation as proof of payment

Some apps ask you to link a registered mobile number first. This sets up your account so you can pay and track future bills.

You can also pay through online banking. Log into your net banking app, enter your customer number, and confirm the transfer.

Why did my electricity bill change automatically?

Japan's government is running an electricity and gas bill subsidy program in 2026. This lowers your bill automatically through your electricity company.

You do not need to sign up or apply. Your electricity provider applies the discount directly to your bill.

The subsidy ran from January through March 2026. It restarted again from July through September 2026.

This subsidy can make your bill amount shift month to month. Do not assume a lower or higher bill means a billing error.

Check your latest bill or your electricity provider's website for the current subsidy rate. The discount amount depends on how much electricity you use.

How to pay utility bills with MailMate

Going home for the holidays? But want your bills paid on your behalf while you’re gone? Consider MailMate! Perhaps you're on an extended trip and you don't have anyone to check your mailbox?

MailMate is a virtual mailbox service that can take care of processing utility payments on your behalf. 

Here’s how it works: 

• Sign up for a MailMate account.

• Use Japan Post’s mail forwarding service to get your mail redirected to MailMate headquarters.

• Go travel and enjoy yourself. 

• We notify you when we receive a utility bill (or any mail!). 

• You click on the “Pay Bill” button in the MailMate dashboard. And we go to the convenience store and pay it on your behalf!

Traveling? You still pay a base fee

Even with your power switched off, you still owe a base connection fee. This fee is based on your amperage, not your usage.

This can add up during a long trip abroad. Switching to a plan with no base fee can save you money.

Some electricity companies, such as Looop Denki, offer no-base-fee plans. Ask your provider if this option fits your situation.

You can also quickly contact customer service through their AI-powered chatbot on their Japanese website. It can assist you with issues like handling overdue payments, checking your contract information, and switching payment methods quickly and efficiently.  

Can I pay my water bill online in Japan? 

You can select automatic bill payment using your credit card or bank account if you fill out an application form in advance. Depending on your prefecture, online applications may be available. For example, if you live in Tokyo, making an account with 東京水道マイネット will allow you to submit your application form through their website for automatic payments. 

Will my power be cut off immediately if I miss the due date?

No. Japanese electricity companies give you a grace period of about 50 to 57 days from your meter reading date. You will get multiple reminder notices before any disconnection happens. This timeline can vary slightly between companies, but an immediate cutoff after one missed payment is very rare.

Can I negotiate a payment plan if I can't afford the full amount?

Yes, most utility companies offer payment arrangements for customers experiencing financial hardship. Contact customer service to discuss options such as splitting the payment into installments or extending the due date. Be prepared to explain your situation and proposed payment schedule. Companies are generally willing to work with customers who communicate proactively rather than simply ignoring bills.

What happens if my power gets cut during a typhoon or extreme weather?

Utility companies typically prioritize safety and may delay scheduled disconnections during severe weather events. However, if your power was already scheduled for disconnection, you should still contact customer service immediately to arrange payment and reconnection. Emergency restoration services may be limited during extreme weather, so it's crucial to resolve payment issues before storm season.

I'm renting an apartment - will unpaid electricity bills affect my lease?

While electricity bills are typically the tenant's responsibility and don't directly impact your lease, some rental agreements include clauses requiring timely payment of utilities. Additionally, if utilities are included in your rent and you're behind on rent payments, your landlord might be unable to pay the electricity bill, potentially affecting service. Check your lease agreement and communicate with your landlord if you're experiencing payment difficulties.

Can I pay someone else's electricity bill if they're unable to?

Yes, you can pay another person's electricity bill at convenience stores, bank branches, or through online payment systems as long as you have their payment voucher or account information. The utility company doesn't require the account holder to make the payment personally. This is particularly helpful for elderly relatives or friends who may need assistance with bill payment.

What should I do if I receive a disconnection notice in Japanese and can't understand it?

Contact the utility company's customer service immediately and ask if they have English-speaking staff available. Many major companies have multilingual support or can arrange translation services. You can also use translation apps to photograph the notice, but don't rely solely on automated translation for important deadlines. Local city halls often provide translation assistance for utility matters as well.

Will unpaid electricity bills appear on my credit report in Japan?

Unlike some countries, Japan doesn't have a centralized credit reporting system that includes utility payments. However, consistently unpaid bills can create problems when applying for new housing, as landlords and real estate agencies may contact your previous utility companies as part of their screening process. Some companies also share information with other utilities, which could affect your ability to establish service at a new address.

Can I set up automatic payments if I don't have a Japanese bank account?

Most utility companies require a Japanese bank account for automatic withdrawal services. However, many companies now accept international credit cards for automatic payments, though this option may have limitations or additional fees. If you don't have either option, consider using services like MailMate that can handle bill payments on your behalf, or ask a trusted friend with a Japanese bank account to help facilitate automatic payments.

What's the difference between the various payment methods in terms of processing time?

Convenience store payments are processed immediately, while bank transfers and credit card payments may take 1–3 business days to reflect in your account. Online payments through apps like PayPay or Line Pay are typically processed within 24 hours. If your power has been disconnected, paying at a convenience store or directly at the utility company office will result in the fastest reconnection time.

I paid my bill but my power is still off after 48 hours. What should I do?

Contact your utility company immediately with your payment receipt or confirmation number. Sometimes payments aren't properly processed due to system errors, incorrect account numbers, or timing issues. The company should be able to verify your payment and expedite reconnection. If you paid at a convenience store, keep your receipt as proof of payment, as these transactions occasionally experience delays in the system.

Can I dispute late fees if I believe they're incorrect?

Yes, you can dispute late fees by contacting customer service with documentation supporting your claim. Common grounds for disputes include processing delays, incorrect due dates, or system errors. Keep records of all payment confirmations and correspondence with the utility company. While companies will review legitimate disputes, the process can take several weeks, so it's better to pay on time initially rather than rely on successful appeals.

What happens to my electricity service if I move to a new apartment?

You must contact your utility company to schedule disconnection at your old address and connection at your new address. This typically requires 3–5 business days' notice and may involve scheduling appointments for meter readings. If you have outstanding bills at your old address, you'll need to settle them before the company will establish service at your new location. Some companies offer online moving services that can handle both disconnection and reconnection simultaneously.

Are there different rules for foreigners regarding electricity bill payments?

No, electricity billing and payment rules are the same for all residents regardless of nationality. However, foreign residents may face additional challenges such as language barriers, unfamiliarity with Japanese payment systems, or difficulty understanding billing notices. Some utility companies offer multilingual customer service specifically to help foreign residents navigate these processes.

What should I do if I'm going on vacation and worried about missing my electricity bill?

Set up automatic payments before traveling, or use a service like MailMate that can handle bill payments while you're away. You can also ask a trusted friend or family member to check your mail and pay bills on your behalf. Some utility companies allow you to prepay for several months of service, though this isn't common. Avoid simply ignoring bills while traveling, as disconnection can occur even during your absence.

Is the government helping lower electricity bills in 2026?

Yes. Japan is running an automatic electricity and gas subsidy through 2026. Your electricity provider applies the discount directly, with no application needed.

Where do I find my customer number on my electricity bill?

Your customer number appears near the top of your paper invoice. You will need this number for phone support, online payments, and any account changes.

Can I check my electricity bill online?

Yes. Most electricity companies offer online access to check your bill and usage. Sign up on your provider's website using the information provided on a past invoice.
