Verification Status: This article is based on publicly available information (no actual usage or transactions by the editorial team).

"It's still five days until the internet is connected at my new place. I can't get any work done with just my smartphone's tethering..." In such situations, Wi-Fi rental services that can be borrowed on a daily basis come to mind. However, what about the actual communication speed and support? When you check reviews, opinions are divided, and many people likely find themselves unsure. This article examines the capabilities of Wifi Rental Shop (Domestic) based on public information and reviews from multiple review sites, providing you with the material to determine whether it suits your needs.

Wifi Rental Shop (Domestic) offers the major appeal of being rentable from one day and returnable by simply dropping it in a mailbox. While there are complaints about communication speed, making it unsuitable for those primarily aiming to watch videos or perform large downloads, it offers high cost performance for business use such as emails and web conferences, or for securing short-term internet access.

How to Survive "A Week Without the Internet"? The Case of Mr. Tanaka

Mr. Tanaka (30s, company employee), who works at an IT company in Tokyo, was facing a dilemma just before his move. Until the optical fiber line at his new home was connected, there would inevitably be a one-week gap. For Mr. Tanaka, who primarily works remotely, this week was a matter of life and death for his job. Even if he tried to get by with his smartphone's tethering, the risk of losing connection during a Zoom meeting and the data cap weighed on his mind. On the other hand, purchasing a long-term contract mobile router for just one week was something he hesitated to do, both in terms of cost and procedures.

That's when a colleague mentioned, "For short-term rentals, Wifi Rental Shop is convenient." Mr. Tanaka immediately visited the official website, where he saw phrases like "Rentals available from as little as 1 day" and "Shipping on weekends and holidays as well." Seeing the price starting from 780 yen for a 1-night, 2-day rental, he thought, "If I can rent for just one week, I might be able to keep costs down," and for the first time, the option of renting became a realistic possibility.

Wifi Rental Shop (Domestic) is a Wi-Fi router rental service available nationwide. Applications can be made online 24 hours a day, with shipping also available on weekends and holidays. Rentals are available on a daily basis, and no additional fees are incurred even if the rental period spans across months. It is designed for people who temporarily need an internet environment, such as for short business trips, hospital stays, moving, telework, or temporary returns to Japan. For someone like Mr. Tanaka, who has the need to "just have reliable internet access for now," this service fits perfectly.

Wifi Rental Shop (Domestic) – A Complete Guide to Pricing Plans and Features

What Tanaka-san was most concerned about next was, of course, "how much it actually costs." When he tried the official website's fee simulation, the plan that suited his usage and the total amount were displayed immediately, giving him a clear budget estimate. Here, we will organize the fee structure and service features as of July 2026.

Pricing plans are broadly divided into three categories based on the rental period. The 1-night, 2-day plan ranges from 780 yen to 1,980 yen; the 1-month plan from 5,850 yen to 14,850 yen; and the 6-month plan from 22,800 yen to 64,400 yen. In all cases, there are no initial fees or administrative charges, and the device cost is included in the rental fee, so the only additional cost is the round-trip shipping fee of 1,100 yen. If you pick up and return the device at a store, this shipping fee is also waived. There are no cancellation fees, making it easy to try for short-term use. Furthermore, registering as a member gives you a 10% point reward, providing a practical discount for repeat users.

The lineup of devices is also extensive, with multiple options available that differ in communication methods and coverage areas, such as UQ WiMAX, Galaxy 5G WiFi, HOME 5G L12, docomo FS050W, and Softbank 601HW. Unlimited plans are also available, but it is important to understand that speed restrictions may apply depending on network conditions.

The service features are summarized as follows.

• Rental from as short as 1 day: You can rent only for the days you need, so no unnecessary costs are incurred.
• Orders by 5:00 PM shipped the same day: Shipping is also handled on weekends and holidays, making it easy to respond to urgent needs.
• Return via Letter Pack (drop in a mailbox): Simply drop the package in a mailbox by 8:00 AM the day after the rental ends. No need to visit a service office.
• Fully charged and operation-checked before shipping: You can start using it immediately from the day it arrives.
• Phone support available: Support is available on weekdays from 9:30 AM to 7:00 PM, and on weekends from 11:00 AM to 6:00 PM, 365 days a year. Having a contact point for when you have problems is reassuring.
• Corporate services also available: Invoice payment is possible, accommodating business use.

After simulating the total cost including round-trip shipping for a one-week rental, Tanaka-san began to feel, "This is much more reasonable than working with the anxiety of tethering."

Real Pros and Cons Revealed from User Reviews

That said, it's only natural to be curious about the "actual user experience" that can't be seen from fees and features alone. Mr. Tanaka also cross-referenced multiple review sites and carefully examined real user feedback. Here, based on reviews obtained from publicly available information, let's look at the real evaluation of Wifi Rental Ya (Domestic) from both the pros and cons perspectives.

The sentiment ratio of reviews, based on a sample of 10 reviews from one review site, shows a clear split: 40% positive, 40% negative, and 20% neutral. The dividing line in evaluations lies in communication speed and ease of procedures.

First, let's look at the positive reviews.

"It was delivered right away! I needed to work from home, so I got WiFi. It was great that the delivery date and time were listed on the site." (Minhyo)

"The pay-as-you-go service is convenient. This price including insurance is good value for money." (Minhyo)

"I rented it due to a sudden hospitalization, but it was comfortable and a lifesaver. The extension procedure was also easy." (A review site)

"The return letter pack was included, and all I had to do was drop it in the mailbox. It was simple." (A comparison site)

From these comments, it's clear that "ease of procedures," "convenience of returns," and "cost performance for short-term use" are highly rated. In particular, the inclusion of a return letter pack is a major advantage for busy business professionals. Mr. Tanaka also felt, "If I can just drop it in the mailbox between meetings, there seems to be no stress with returns."

On the other hand, there are also many critical opinions.

"It's unusable, expensive, and support is bad. I rented it as unlimited, but I couldn't even watch videos." (Minhyo)

"It's extremely slow. Constantly super slow, and I can't even play games properly. It keeps cutting out during remote work." (Minhyo)

"I hope your money and time aren't wasted. The communication speed has been slow since the first day of rental." (Minhyo)

Most of the negative reviews focus on "slow communication speed." For uses requiring large data communication, such as video streaming, online gaming, or app updates, it seems there are moments of frustration. Additionally, some models reportedly experience frequent disconnections, with cases where it interferes with web conferences during remote work. Complaints about poor support and high fees are also seen, but these are often mentioned alongside speed issues.

Mr. Tanaka calmly analyzed these reviews. His main uses are email, chat, and one or two Zoom meetings per day. He rarely watches videos for long periods or downloads large files. "Many people dissatisfied with speed are using it for video streaming or gaming. For my usage, it might be acceptable," he thought, and decided to move on to the next step: comparing it with competing services.

Thorough Comparison with 3 Competitors｜What Makes Wifi Rental San Different?

"Should I really go with Wifi Rental San?" Tanaka picked out several similar short-term rental services and created a comparison table to consider. Here, we clarify the position of Wifi Rental San (Domestic) by focusing on the differences from three representative competitors.

*Figures are based on publicly available information from each company's official website and comparison sites (surveyed in July 2026). Fees are subject to change, so check the latest on each official site. Airport pickup/return availability and speed throttling conditions for unlimited plans vary by company.

The strength of Wifi Rental San (Domestic) is, above all, its pricing starting from a low daily fee of 390 yen (based on a comparison of publicly available fees from multiple companies) and the ease of "zero cancellation fee." With a 10% point reward for membership registration, it becomes even more advantageous for those considering repeat use. The inclusion of a return Letter Pack that can be completed by simply dropping it in a post box is also a clear advantage not offered by other companies.

On the other hand, it is important to note that it is not suitable for long-term use. There are only plans up to 6 months, so if you plan to use it continuously for several months or more, other companies may be more suitable. Additionally, delivery to Hokkaido, Okinawa, and Kyushu may not arrive the next day, so those in remote areas who need it urgently should be careful. Those who need airport pickup and return should also choose other companies that offer this service instead of Wifi Rental San.

Ultimately, who should choose which? For short-term use (1 day to a few weeks), those who want to keep costs as low as possible and minimize the hassle of returning the device should consider Wifi Rental San (Domestic) as their first choice. For those who require airport use or plan for long-term use, it is wise to consider other options as well. It is recommended to first consult via free registration and free consultation.

Simulating the Process from Application to Return

After completing his comparison, Mr. Tanaka finally moved to the application stage. However, as a first-time rental service user, he still had concerns about the complexity of the procedures. So, he decided to simulate the actual usage flow.

The process from application to return at Wifi Rental Shop (Domestic) is completed in the following 6 steps.

1. Select the model, delivery method, rental period, and options on the official website: Using the fee simulation function, the total amount for the selected conditions is displayed in real time. Mr. Tanaka chose a model suitable for remote work and confirmed the rental fee for one week on the spot.
2. Place an order (same-day shipping for orders placed by 5 PM): Since the service operates on weekends and holidays, you can arrange it immediately even if you decide to rent on a weekend. Mr. Tanaka placed his order at 3 PM on Wednesday, making it in time for same-day shipping.
3. Product arrival (as early as the next day): The device is fully charged and operation-checked before shipment, so you can start using it immediately upon arrival. In Mr. Tanaka's case, it arrived by Thursday morning. However, for remote areas such as Hokkaido, Okinawa, or Kyushu, next-day arrival may be difficult.
4. Start using: The rental start date is the arrival date. Mr. Tanaka immediately turned on the Wi-Fi router and connected his computer and smartphone. He was able to handle Zoom meetings without any issues.
5. Return (via Letter Pack drop-off in a mailbox or courier): You can drop it off by 8 AM the morning after the rental end date. Simply place the device in the included Letter Pack and drop it into a nearby mailbox. Mr. Tanaka dropped it off before leaving for work and felt almost no hassle with the return.
6. Receive a return completion email: Once the product's arrival is confirmed, a completion email is sent. This concludes all procedures.

What particularly reassured Mr. Tanaka was the fact that the return Letter Pack was included from the start. He reflected, "Not having to search for a box or write a shipping label for the return was easier than I imagined." By utilizing free registration and free consultations, you can consult in advance before applying, even if you are unsure about which model to choose. The procedural hurdles are surprisingly low.

Ultimately, Who is Wifi Rental-san (Domestic) Recommended For?

After a series of investigations and comparisons, Mr. Tanaka decided to use Wifi Rental-san (Domestic). Finally, let's clearly state the essence of this service that emerged from public information, in the form of "who it suits" and "who it doesn't."

Wifi Rental-san (Domestic) is suitable for the following types of people:

• Those who mainly use it for short-term periods (1 day to a few weeks): You can rent on a daily basis with zero cancellation fees. Use it only for the necessary period, then simply drop it in the mail. It's ideal for spot use, such as bridging a move, sudden hospitalization, or temporary return to Japan.
• Those who use it for business purposes centered on email, chat, and web conferencing: If you don't watch videos or perform large downloads, dissatisfaction with communication speed will be significantly reduced. In fact, there are multiple reviews praising its use for telework.
• Those who value simplicity of procedures and cost: Starting from 390 yen per day, including a return letter pack, and a fee simulation on the website. This hassle-free design resonates especially with busy people. The figures of a 98.8% repeat request rate and No.1 customer satisfaction (Rakuten Research, 2023 survey) likely reflect support for this ease of use.

On the other hand, we recommend considering other options for the following people:

• Those who require video streaming or large downloads: The most common complaint in reviews is "slow communication speed." Even with an unlimited plan, there is a possibility of speed throttling, making stressful situations unavoidable.
• Those who assume long-term use of several months or more: There are only plans up to a maximum of 6 months, making other companies more suitable for long-term use.
• Those who require next-day delivery to remote areas: In places like Hokkaido, Okinawa, and Kyushu, delivery may take time. If you are in a hurry, consider other companies that offer airport pickup.
• Those who seek extensive support: Although phone support is available, there are also complaints about support response in reviews. It is wise to resolve any concerns through a free consultation before applying.

"If you're still unsure whether it suits your usage," using the free registration and free consultation is the least risky first step. You can consult with a professional about device selection and speed concerns before actually applying. It costs nothing, and you can gather decision-making material in just a few minutes. That's why it's worth trying first.
