(Renting a car in Japan gives your itinerary tremendous flexibility, convenience, and can even save you money. Utilizing a price comparison site to efficiently secure the right rental company is crucial.)
1. Introduction to ToCoo! Rent a Car
Japan has numerous car rental brands. Beyond major companies like Toyota Rent a Car, ORIX, Nissan, Times CAR RENTAL, Nippon Rent-A-Car, and Budget, there are also dozens of local regional operators. The major advantage of ToCoo! Rent a Car is its vast network: it compares around 50 car rental companies simultaneously across approximately 3,000 pickup locations nationwide. No matter which Japanese city you plan to visit, you can organize your rental car in one convenient place.
In addition to finding affordable rental companies and vehicle models, ToCoo! regularly rolls out unique proprietary add-ons and value plans. These include pocket Wi-Fi discounts, free ETC card rentals, ToCoo! Additional Support (T.A.S.) insurance coverage, complimentary accommodation packages, Anshin Travel medical plans, unlimited expressway toll packages, express pass plans, snow tire guarantees, and early bird discounts. These diverse, constantly updated perks help you shave even more off your travel budget.
2. How to Use ToCoo! Rent a Car & Exclusive Promo Codes
Now that you know the basics and advantages of ToCoo! Rent a Car, let's look at how to use the site. Following recent updates, ToCoo! offers a multilingual interface that is clear, intuitive, and easy to master in just a few minutes. Below is a step-by-step walkthrough of the reservation process and key details to look out for.
Once you arrive on the ToCoo! Rent a Car homepage, just like other comparison aggregators, you simply select your arrival airport or region, travel dates, and rental times. The search engine will automatically display matching vehicles. The "Additional Options" menu on the bottom right is collapsed by default; opening it lets you filter by car category, built-in GPS, Collision Damage Waiver (CDW), special plans, and more. If you leave these blank, the system automatically pulls all available deals.
Next, you will see all search results matching your criteria, sorted by default from lowest to highest rental rate. At the top, you can switch between "Search by Outlet" and "Search by Plan"—the former focuses on comparing different rental operators, while the latter compares promotional packages (since a single rental company can offer multiple distinct packages).
You will also find shop profiles, maps, and plan details. Clicking into them displays complete outlet information, including opening hours, exact locations, transit access times, and regular closing days. The "ToCoo! Anshin Travel Plan" shown in the screenshot is just one example; scroll down to browse many other options.
Once you pick your preferred car, rental brand, and plan, you enter the detailed booking flow, which consists of 4 main steps. First, you will configure rental options such as child or baby safety seats, GPS navigation devices, ETC card rentals, and disclaimer insurance. Please note that rental options vary slightly between companies; for example, Nissan Rent a Car (pictured) requires mandatory purchase of Collision Damage Waiver (CDW), whereas other companies may list it as optional. The option subtotal will automatically calculate at the bottom.
Next, you need to input the primary driver's information, flight number, contact phone number, and other essentials. This page also re-displays all selected add-ons for your confirmation. You might notice that the grand total here looks different from the initial search results page; that is because this checkout page shows the tax-inclusive price, whereas earlier listings displayed tax-exclusive base rates.
Finally, near the bottom of the page, you will notice a section called "ToCoo! Options." These are proprietary services provided directly by ToCoo! Rent a Car, such as travel insurance, pocket Wi-Fi rentals, and ETC Passes. Because the "T.A.S. Car Rental Insurance Plan" is mandatory, your credit card will still be charged a small upfront fee even if you select "Pay at pickup"—this charge covers T.A.S. and ToCoo! options. The exact differences between ToCoo!'s T.A.S. and a rental company's CDW are explained in the next section.
After entering your credit card details and completing the reservation online, you will receive a confirmation email. When picking up your vehicle at the counter, simply present the reservation number (TC-xxxxxx-xxxxxx) along with your passport, original domestic driver's license, and an International Driving Permit (IDP) (or official Japanese license translation if holding an eligible license such as Taiwan, Switzerland, Germany, etc.). If you chose "Pay at pickup," you will settle the vehicle rental balance at the counter via credit card or cash.
By entering your reservation number, you can easily log into ToCoo! Rent a Car at any time to review and manage your booking, making the entire experience remarkably smooth.
3. Understanding ToCoo! Additional Support (T.A.S.) Insurance
Many travelers wonder: What exactly is covered by the mandatory T.A.S. insurance on ToCoo! Rent a Car, and how does it differ from standard rental company insurance? Here is a clear breakdown.
When booking car rental in Japan, insurance generally splits into "Compulsory Insurance (Basic Liability)" and "Voluntary Insurance (Optional Add-ons)." Basic liability insurance is mandated by Japanese law and included in every base rental price. If an accident occurs, it covers major third-party bodily injury, property damage, and vehicle damage, with the driver only responsible for the minimum deductible (免責金額 / excess).
The first voluntary layer is the Collision Damage Waiver (CDW / 免責補償制度). The primary purpose of CDW is to waive the deductible mentioned above, meaning you pay zero excess for third-party property and vehicle damages. On ToCoo! Rent a Car, the "Collision Damage Waiver" option listed under each company's rental add-ons refers to this CDW.
However, when an accident occurs, it disrupts the rental company's regular operations—the damaged or stolen car cannot be rented out while undergoing repairs or cleaning. To compensate for lost revenue, the rental company charges the driver a Non-Operation Charge (NOC / 營業損失賠償), which typically ranges from 20,000 to 50,000 JPY. Even if you purchase standard CDW, you remain liable for NOC.
This led to the creation of comprehensive premium packages that waive NOC as well (often marketed as Super CDW, Peace of Mind, or Zero Excess coverage). These plans mean you pay nothing out of pocket after an accident, and they often include perks like roadside assistance, emergency refueling, flat tire replacement, and towing. ToCoo!'s T.A.S. is specifically designed to cover the NOC, but it does NOT cover the standard deductible (CDW). Therefore, you must combine company-level CDW with ToCoo!'s T.A.S. to achieve true full zero-excess coverage.
(If you only have T.A.S., it only covers NOC and is not full comprehensive coverage. Hence, when booking on ToCoo! Rent a Car, I strongly recommend adding the rental company's Collision Damage Waiver (CDW) as well—even if marked optional—so you can drive across Japan with total peace of mind.)
A closer look reveals that ToCoo!'s T.A.S. fee is slightly higher than some rental companies' in-house NOC waiver fees. However, ToCoo! often offers lower baseline vehicle rates and bundled promotions, so the total combined package is frequently cheaper overall. It simply depends on the specific vehicle and coverage package you prefer.
4. ToCoo! Expressway Pass (Unlimited Toll Package)
Another unique highlight that sets ToCoo! Rent a Car apart from other aggregators is their exclusive fixed-rate expressway toll service: the ToCoo! Expressway Pass (TEP). In short, it allows you to enjoy unlimited access to expressways across Japan for a flat fee over a specified number of days—an all-you-can-drive toll pass!
In addition to the nationwide All-Japan TEP, regional passes are also available for Hokkaido, Kyushu, and Okinawa. The available durations and prices are summarized below:
(As shown in the table, longer durations offer a lower average daily cost. For travelers planning extended road trips or frequent long-distance highway driving, this pass can deliver substantial savings.)
As I mentioned in my general Japan car rental guide, regional highway companies in Japan have historically issued localized ETC passes for areas like Hokkaido, Central Japan (CEP), Tohoku (TEP), Kyushu (KEP), and San'in-Setouchi-Shikoku (SEP). For regional self-drive itineraries, you can also consult my dedicated guides on Hokkaido car rental and Kyushu car rental.
Generally speaking, if you plan to drive long distances across multiple regions and use expressways extensively, ToCoo!'s all-you-can-drive TEP is an ideal match. However, if your road trip is confined to a single designated region, that area's regional ETC pass may prove more cost-effective.
(Major metropolitan areas like Osaka and Tokyo—in the Kansai and Kanto regions—do not have dedicated regional ETC passes offered by expressway operators. If you plan to drive on highways frequently within Kansai or Kanto, ToCoo! Rent a Car's TEP pass may be the most economical choice. I recommend calculating your estimated tolls using the NEXCO Expressway Toll Calculator before deciding.)
5. Important Tips & Things to Know
- All optional services offered directly by ToCoo! (such as T.A.S. insurance, Wi-Fi routers, and ETC Passes) are charged to your credit card at the time of online reservation. The vehicle rental fee payable to the rental company can be paid either online upfront or at the counter upon pickup.
- If you are more than 1 hour late past your scheduled pickup time without prior notice, your reservation may be automatically cancelled and charged to your card. If your flight or transit is delayed, be sure to notify the rental shop in advance to keep your booking valid (rental charges will still apply from the original scheduled start time).
- The Japanese-language version of the ToCoo! website might occasionally display lower domestic rates, but it is strictly reserved for residents of Japan. Bookings made by overseas tourists through the Japanese portal are subject to automatic cancellation, so please always use the international multilingual version.
- The T.A.S. insurance fee is calculated on a 24-hour calendar day basis; partial days are rounded up and billed as a full day.
- Cancellations made within 6 days of the pickup date incur a cancellation fee charged directly to your credit card. If you cancel within 24 hours of completing the reservation, or at least 7 days before pickup, no cancellation fee applies and ToCoo! add-on option fees are fully refunded.
- If you rent an ETC card through ToCoo!, a temporary deposit of 15,000 JPY is pre-authorized on your credit card. Once the ETC card is returned and actual toll charges are reconciled, the deposit balance will be refunded (this standard procedure mirrors individual rental companies). However, if you purchase an unlimited TEP toll pass, no security deposit is required.
- Rental ETC cards reserved through ToCoo! are shipped to airport post offices for pickup. Please verify the official post office opening hours in advance to avoid arriving outside counter operating times.
That wraps up my comprehensive guide to ToCoo! Rent a Car! Thanks to its extensive partnerships with major Japanese car rental operators, ToCoo! often offers cheaper rates than booking directly, paired with an immense inventory across popular destinations like Okinawa, Tokyo, Hokkaido, and Kyushu. It is an intuitive, highly dependable comparison tool that I wholeheartedly recommend testing out before your trip—it might save you significant time and travel expenses!
