Following Japan's complete deregulation of electricity retail in 2016 and urban gas retail in 2017, bundled services that consolidate electricity, gas, and internet with a single provider have rapidly become popular. The appeal lies in "bundle discounts" that reduce monthly charges when multiple utility services are contracted through the same company, with some households achieving fixed-cost savings of up to approximately 25%.
However, while consolidating contracts streamlines cancellation procedures, it also means you'll face the full impact of a provider's operational troubles—such as bankruptcies that have occurred in the past with some power companies. This article presents the advantages and disadvantages in a balanced way and explains how to choose the best option for foreign residents.
Patterns where telecommunications companies also provide electricity and gas.
Patterns where traditional regional power companies like Tokyo Electric Power and Kansai Electric Power offer their own bundles.
| Service Plan | Electricity | Gas | Internet | Total Monthly |
|---|---|---|---|---|
| Individual contracts (Tokyo Electric + Tokyo Gas + Docomo Hikari) | ¥11,500 | ¥6,200 | ¥4,400 | ¥22,100 |
| Tokyo Gas Triple Discount (Electricity + Gas + Docomo Hikari) | ¥11,200 | ¥5,900 | ¥3,300 | ¥20,400 (saves ¥1,700/month) |
| SoftBank Three-Service Bundle | ¥11,000 | ¥6,000 | ¥3,180 | ¥20,180 (saves ¥1,920/month) |
| NURO Hikari Denki + NURO Hikari + NURO Hikari Gas | ¥10,800 | ¥5,800 | ¥4,180 | ¥20,780 (saves ¥1,320/month) |
Bundle discount savings typically amount to ¥1,300–¥1,900/month, or roughly ¥16,000–¥23,000/year. Because the best option varies by household composition and electricity consumption, be sure to recalculate using your own usage data.
An increasing number of providers allow you to complete electricity and gas applications entirely on their websites by uploading photos of your ID. While many sites are Japanese-only, SoftBank Denki and NURO Hikari Denki offer English-language websites and English phone support.
Electricity and gas contracts typically don't require a credit check (since they're public utilities), but internet contracts require either a credit card or automatic bank transfer. If you're concerned about credit history, look for providers that accept prepaid cards, or consider choosing a property where you can combine internet payments with rent.
Discounts of ¥1,300–¥2,000/month are typical with three-service bundles, translating to roughly ¥20,000/year in savings.
Consolidating electricity, gas, and telecom billing with one provider makes household budget management significantly easier. For foreign residents less familiar with Japanese, having to understand just one type of bill statement is a major advantage.
Rakuten Denki and au Denki offer points rewards, which you can redeem for mobile charges or retail purchases.
When moving out and moving in, cancellation and service activation with the same provider can be handled in one go. You can complete everything with a single phone call or online moving form.
Major providers' apps display your electricity and gas usage in graphs, motivating conservation efforts. Some apps offer English-language interfaces.
If your telecom contract has a 2- or 3-year commitment period, early cancellation incurs fees. While electricity and gas usually have no commitment period, they lose bundle discount benefits if you cancel telecom, creating a de facto lock-in on your internet service.
There have been past instances of power company bankruptcies, forcing customers to go through sudden switching procedures. Bundling electricity, gas, and telecom with a single provider means a provider's troubles affect all your utilities at once. Choosing well-capitalized major providers like Tokyo Gas, SoftBank, or NTT-affiliated companies is the safest approach.
Bundled contracts can only continue within the same provider's service area. For example, if you move outside Tokyo Gas's coverage area (such as to a rural region), you'd have to cancel only the gas portion, and your bundle discount disappears.
Each provider has different pricing structures, contract terms, and perks, so finding the best fit takes time. Using comparison sites like Kakaku.com and Enechanj can help you compare options efficiently. If you want to cut communication costs even further, slashing monthly telecom bills to under ¥5,000 with budget SIMs and fixed broadband is worth exploring.
Bundled utility services offer monthly savings of ¥1,300–¥2,000 (or ¥16,000–¥23,000/year) and multiple advantages including consolidated billing, multilingual support, and points rewards. However, early termination fees, provider bankruptcy risk, and relocation constraints are real drawbacks. If you plan to stay long-term, a major provider's bundle makes sense; if you're staying short-term, individual contracts with no commitment periods offer more flexibility. Use comparison sites to find the provider that best matches your usage patterns and length of stay.
