Tanaka faced a pressing dilemma: "We can't operate without the internet." For store-based businesses like restaurants, beauty salons, and clinics, a stable internet connection is essential for cashless payment terminals, reservation systems, and BGM streaming. However, fiber optic line installation typically takes one to two months, and it's not uncommon for it to miss the opening day.

BizAir is a 5G-compatible plug-in Wi-Fi service designed for corporations and sole proprietors, created to support businesses in these "right now" moments. It can be used simply by plugging it into an outlet, with activation possible in as little as three days. Its biggest feature is eliminating the waiting time and hassle of on-site installation.

When you break down the main specifications, the design is clearly tailored from a business owner's perspective:

• No installation required: Just plug it into an outlet. No need for technician visits or drilling holes in walls.
• Ready to use in as little as 3 days: Fast turnaround from application to device delivery.
• 5G compatible: Uses three networks—WiMAX2+, au 4G LTE, and au 5G—for high-speed communication.
• Two SSIDs provided: Allows you to separate a business-use network from a free Wi-Fi network for customers.
• Supports up to 16 simultaneous connections: Connect POS terminals, tablets, and staff smartphones at the same time, depending on device specs.
• Long-term and short-term rental options: In addition to a 2-year long-term contract, short-term rental plans of up to 6 months are also available.

On one review site, a user commented, "Since it required no installation and was ready to use right away, it was a lifesaver before opening." This is exactly the kind of situation Tanaka was in, and the ability to get a fast, effective internet solution is BizAir's primary value.

BizAir Pricing Plans and Campaigns: A Complete Guide [2026 Latest]

"Okay, I get that it's ready to use. But how much does it cost?" Tanaka then began looking into the costs. With limited startup funds, he wanted to keep monthly fixed expenses as low as possible.

BizAir's pricing structure consists of three plans based on data capacity. As of July 2026, the monthly fees (tax included) are as follows:

All plans come with zero initial and installation fees. Additionally, a first-month free campaign is available exclusively for online applications, keeping the actual entry barrier quite low.

On the other hand, canceling a long-term rental plan (2-year contract) early incurs a cancellation fee of up to 21,780 yen (tax included). This is a point you'll want to be aware of before signing a contract. With short-term rental plans, you can use the service flexibly for up to six months without worrying about penalty fees.

Campaign details and pricing may vary depending on the period and region, so we recommend checking the latest campaigns on the official website.

No Construction Required, 5G Compatible… An Honest Breakdown of BizAir’s Pros and Cons

“The convenience and low cost are appealing, but I also want to know the downsides.” Tanaka read through multiple review sites and comparison articles, digging up not only BizAir’s strengths but also its potential pitfalls. Here, we organize the pros and cons that emerge from publicly available information, including insights into who might be most affected.

Pros

Cons

In reviews, you’ll find comments like “Perfect for a store. Great value for money,” alongside warnings such as “Speed varies by area, so advance confirmation is essential.” Understanding both the pros and cons is key to determining whether BizAir fits your specific business environment.

Fiber Optic vs. Pocket Wi-Fi: A Thorough Comparison – Why BizAir is the Right Choice

Mr. Tanaka also compared other options besides BizAir: fiber optic lines, mobile Wi-Fi (pocket Wi-Fi), and other providers' stationary Wi-Fi (home routers). He summarized the features of each in a table to find the best internet setup for his café.

While fiber optic offers superior stability, it requires time and cost for installation. Mobile Wi-Fi is portable, but compared to stationary BizAir, it may fall short in connection stability and the number of simultaneous connections. Other providers' stationary Wi-Fi is mainly for personal use, with limited support for business needs like separating guest Wi-Fi or short-term rentals.

For Mr. Tanaka's café, with no time before opening and the need to simultaneously support payment terminals, BGM streaming, and free guest Wi-Fi, BizAir was the perfect fit. It requires no installation, can be activated the same day, and offers two SSIDs. Cost-wise, it also significantly reduces the monthly fee compared to fiber optic, making it a budget-friendly choice for the early stages of business.

Real User Reviews and Feedback on BizAir

"Online reviews are worth reading precisely because they don't just say good things." Tanaka cross-checked multiple review sites and articles. Overall, positive opinions dominate, but there are also a certain number of complaints about speed and cancellation fees.

Positive Reviews

"No installation needed, so I could use it right away. It was a lifesaver before opening my business." (From a review site)

"Perfect for store use. Great value for money." (From another review site)

"5G-compatible, so the connection is fast. Online meetings are smooth." (From multiple review articles)

"Easy to set up, and I don't need construction work every time I move." (From a review site)

These comments show that the ease of use without installation and the high cost-performance for store use are well-regarded.

Negative Reviews

"Speed varies by area, so advance confirmation is essential." (From a review site)

"The cancellation fee is a drawback. You should check the contract terms beforehand." (From another review site)

"It might not be suitable for businesses handling large amounts of data." (From a review article)

Complaints about speed are mainly due to the radio wave environment. Since BizAir uses a wireless connection, the actual speed can fluctuate depending on the building's structure and surrounding signal conditions. This risk can be significantly reduced by checking the coverage area before installation. While the high cancellation fee is tied to long-term contracts, choosing a short-term rental plan eliminates the worry of early termination penalties.

Although it is difficult to precisely quantify the sentiment ratio of reviews, positive opinions dominate on multiple review sites, with particularly high satisfaction levels regarding "speed of setup" and "low cost."

Who is BizAir for? Suitable and Unsuitable Users

Based on the information above, Tanaka is now confident that "BizAir is the right fit for my café." So, let's break down exactly which types of businesses BizAir suits best, and conversely, which cases should consider other options.

Who BizAir is for

• Those who need internet set up quickly, such as before opening a business or right after relocating
• Operators of small-scale restaurants, beauty salons, clinics, coin laundries, and similar businesses
• Those who need a line for cashless payment terminals or tablet POS systems
• Those who want to offer free Wi-Fi to visiting customers
• Those considering short-term use, such as event booths or pop-up stores
• Those in rental properties where drilling holes in walls is not allowed, or who want to avoid the hassle of restoring the property to its original condition

Who BizAir is not for

• Large offices with dozens of employees requiring constant, high-volume data communication
• Businesses operating in basements or reinforced concrete areas with poor signal reception
• Those using business systems that require a fixed IP address
• Those with applications where low latency is a top priority, such as live streaming online games

Tanaka's café perfectly matches the conditions of "who BizAir is for." This is because it combines all the key factors: no time before opening, a small-scale store, the need to provide Wi-Fi for customers, and a rental property.

Note that sole proprietors and freelancers can also apply for BizAir. Additionally, it supports up to 16 simultaneous connections, and with the zero initial cost and first-month-free campaign, you can start without risk. For connecting just a few staff members and a handful of devices, you are unlikely to experience major speed issues.

Frequently Asked Questions

Is construction really not required?

Yes, with BizAir you just plug it into a power outlet and start using it. No technician visit or wall drilling needed, and activation can be as fast as 3 days. However, you need a power source and to be within 5G/4G coverage.

Is the connection speed stable?

In 5G areas, speeds are fast, but in basements or deep inside reinforced concrete buildings, speed may drop. Also, connecting many devices at once can slow things down, so it's not ideal for large offices.

How much is the early termination fee?

For the long-term rental plan (2-year contract), early cancellation incurs a fee of up to ¥21,780 (tax included). The short-term rental plan (up to 6 months) has no cancellation penalty.

Can sole proprietors apply?

Yes, BizAir is for corporations and sole proprietors. Sole proprietors can apply and use it to set up internet before opening their business. However, the contract must be under the business name.

How many devices can connect simultaneously?

Up to 16 devices can connect at once, depending on device specs. You can connect POS terminals, tablets, and staff smartphones, but more devices may reduce speed.

Can I offer free Wi-Fi to customers?

Yes, BizAir provides two SSIDs so you can separate business and guest Wi-Fi. Isolating the guest network maintains security while offering Wi-Fi to customers.

How do I check coverage?

You can check coverage on the official website. Outside 5G areas, it switches to 4G LTE, which may be slower. We recommend verifying your location is covered beforehand.
