Inside a light truck parked in the construction site's parking space, Kenta Tanaka (35) gripped his smartphone and sighed. He had just received a call from a client asking, "Have you confirmed the order form we faxed earlier?" It would be another two hours before he could return to the office. Because he couldn't confirm the fax, material arrangements would be delayed again today, throwing off the entire site schedule. For Mr. Tanaka, who already felt burdened by the space required for a dedicated fax machine and the maintenance costs of a phone line, this "returning to the office just for fax" had been a small, unresolved thorn in his side ever since he became self-employed.
Conclusion: eFax is an internet fax service that allows you to send and receive faxes via smartphone or PC without using any fax machines or phone lines. With a monthly allowance of 150 free pages and phone numbers selectable from 57 cities nationwide, it simultaneously resolves the issues of "delayed fax confirmation" and "fixed cost burdens" for sole proprietors and small corporations who are frequently on the go.

eFax is a cloud-based service that eliminates the need for a dedicated fax machine, allowing you to send and receive faxes entirely from your PC or smartphone. Received faxes arrive as PDF attachments in your email, while outgoing faxes are sent by transmitting digital documents through eFax's servers directly to the recipient's fax machine. This means no paper, no ink, and no telephone lines are required whatsoever.
In Mr. Tanaka's case, simply opening his smartphone in the parking lot at a job site allows him to instantly view purchase orders from clients as PDFs and immediately send a confirmation fax in return. There is no longer any need to return to the office, eliminating delays in material procurement. This represents the fundamental shift that eFax delivers.
Key features include:
- No Fax Machine Required: Send and receive from anywhere using just a PC or smartphone
- 150 Free Pages per Month: Send up to 150 pages each month with no additional charges
- Instant PDF Viewing of Received Faxes: Delivered as email attachments, allowing you to check contents on your smartphone even while away from the office
- Choose Fax Numbers from 57 Cities Nationwide: Select numbers starting with area codes like "03" to maintain professional credibility
- Encrypted Communication for Security: Suitable for industries handling confidential information, such as healthcare and nursing care
eFax launched its services in Japan in 2010 and surpassed 20,000 accounts by February 2013. Already, many sole proprietors and small corporations have been liberated from the traditional constraints of "location" and "time" associated with faxing.
Comprehensive Guide to eFax Pricing Plans and Free Allowance [Latest 2026]
eFax operates on a simple monthly subscription model. The key highlight is that up to 150 fax pages can be sent for free every month. This free allowance is included in the basic monthly fee, with no additional charges for transmissions within this limit.
For sole proprietors like Mr. Tanaka, who runs a construction business, monthly fax transmissions primarily consist of quotes, purchase orders, and invoices, rarely exceeding 150 pages. In fact, for many small-scale businesses, this free allowance offers a highly practical volume.
Payment methods vary depending on the contract type. Corporate contracts allow payment via credit card, bank transfer, or direct debit. In contrast, individual contracts, including those for sole proprietors, accept credit cards only. Fees are prepaid; if usage exceeds the free allowance, the excess amount is immediately charged as a deposit to the registered credit card.
Invoices are issued as PDFs via email and are fully compliant with the invoice system, minimizing administrative workload. We recommend checking the official website for the latest monthly rates and campaign information.

"It's great because you don't have to go out of your way to buy a fax machine. It's easy and doesn't take up space!" (Review site)
"I thought it would be convenient, but there aren't many situations these days where using a fax is necessary, so it seems I won't have much use for it." (Review site)
In other words, the value of eFax changes significantly depending on "whether your industry or business relationships require fax." In industries where fax remains an established business custom, such as construction, healthcare, and nursing care, the benefits of being freed from spatial and time constraints stand out. On the other hand, in environments where all transactions are completed via email, the necessity for adoption becomes lower.
