Why Owning a Car in Japan is So Expensive

To appreciate the value of renting and sharing, you first need to understand the financial reality of car ownership here. It is not just about the price of the vehicle. The running costs can be shocking for those coming from countries where keeping a car is cheap.

The Parking Problem:

In Japanese cities, you cannot register a car unless you can prove you have a parking space. This is called Shako Shomei. In central Tokyo, a monthly parking spot can easily cost 30,000 to 50,000 yen. That is 600,000 yen a year just to store the metal box.

The Shaken System:

Every two years, every car must undergo a mandatory safety inspection called Shaken. This is thorough and expensive. Even for a standard car in good condition, the fees and taxes associated with Shaken can run between 100,000 and 150,000 yen.

Automobile Taxes:

Every May, you receive a tax bill based on the engine size of your car. This ranges from roughly 30,000 to 50,000 yen annually.

When you add insurance and gasoline to this, you are looking at a significant portion of your salary going towards a vehicle you might only use on weekends. This financial reality is the primary driver behind the boom in alternative mobility solutions.

Option 1: The Traditional Rent-a-Car

The first option is the classic rental car. In Japan, this is known as “Rent-a-Car.” Major players include Toyota Rent-a-Car, Nippon Rent-a-Car, Orix, and Nissan.

When to Choose Rental

Rental cars are the best choice for longer trips. If you are planning a three-day excursion to Hokkaido or a week-long road trip around Kyushu, a traditional rental is usually more cost-effective. They charge by the day (24-hour blocks), and the daily rate drops the longer you rent.

The Benefits

• Cleanliness: The cars are professionally cleaned after every user.
• Variety: You can choose specific models, from large vans for moving furniture to luxury sedans for business trips.
• One-Way Options: Many companies allow you to pick up the car in one city and drop it off in another (for an extra fee), which is great for cross-country travel.

The Drawbacks

• Business Hours: You typically have to pick up and return the car during the shop’s operating hours (usually 8:00 AM to 8:00 PM).
• Paperwork: Every time you rent, you have to go to the counter, show your license, and sign papers. It takes time.
• Fuel: You must return the car with a full tank of gas (Mantan).

Option 2: The Car Sharing Revolution

Over the last decade, “Car Sharing” has transformed mobility in Japan. The dominant player is Times Car Share (run by the parking lot company Times24), followed by Careco and Orix Car Share.

How It Works

Car sharing is a membership-based service. Once you are a member, you get an IC card. You book a car using a smartphone app, walk to the parking lot (often just a regular coin parking lot with a yellow sign), touch your card to the reader on the car window, and the door unlocks. The keys are inside. There is no staff, and the service is available 24/7.

When to Choose Car Sharing

This is perfect for short, spontaneous trips. Need to go to Costco for three hours? Need to pick up a friend from the station? Want to go for a quick night drive? Car sharing is charged in 15-minute increments.

The Benefits

• Flexibility: You can book 3 minutes before you need the car.
• Gas Included: This is the biggest surprise for many expats. You do not pay for gas. The cost of fuel is included in the usage fee. There is a fuel card inside the car’s visor that you use to fill up if the tank gets low.
• Night Packs: Many services offer incredible “Night Pack” deals (e.g., 6:00 PM to 9:00 AM) for a flat rate of around 2,500 yen plus a distance charge.

The Drawbacks

• Cleanliness: You rely on the previous user to keep the car clean.
• Availability: On sunny weekends or holidays, cars in popular residential areas get booked up quickly.
• Distance Charges: For longer drives (usually over 6 hours), a per-kilometer charge is added, which can make it more expensive than a traditional rental.

The License Hurdle: IDP vs. Japanese License

Before you download any apps, you need to ensure you are legally allowed to drive. This is where many foreigners get tripped up.

The International Driving Permit (IDP):

If you are a tourist or have just arrived, you can drive with an IDP issued in your home country (based on the 1949 Geneva Convention). However, this is only valid for one year from your date of entry into Japan.

Crucially, you cannot just leave Japan for a weekend and come back to renew this year. If you are a resident, Japan treats the IDP as a temporary measure.

The Japanese License:

To use car sharing services like Times Car Share, you almost always need a valid Japanese Driver’s License. They rarely accept IDPs for membership registration because the system is automated.

Traditional rental car counters (Toyota, Nippon) will accept an IDP.

Therefore, if you plan to stay in Japan long-term, converting your license to a Japanese one (Gaimen Kirikae) should be a top priority.

Electric Vehicles and Sustainability

Japan is slowly but surely embracing Electric Vehicles (EVs), and rental fleets are a great place to try them out.

If you use car sharing services like Careco or e-ShareMobi (by Nissan), you will find a higher percentage of electric vehicles available. Driving a Nissan Leaf or a sleek Tesla for a few hours is a great way to experience the technology without the commitment of buying.

For traditional rentals, you can specifically request hybrid models like the Toyota Prius or Aqua. These are incredibly fuel-efficient, which saves you money on long road trips since you have to pay for gas.

Charging Considerations:

If you rent an EV, make sure you understand the charging network. Japan has many CHAdeMO fast chargers at highway service areas (Michi-no-Eki) and convenience stores. Most rental EVs come with a charging card that allows you to plug in without paying cash at the station.

Step-by-Step: How to Use a Car Share Service

Since car sharing is the more complex system to set up, let’s walk through the process. We will use Times Car Share as the example, as it is the largest, but the process is similar for others.

1. Application:

You apply online. You will need to upload photos of your Japanese Driver’s License and a credit card in your name. You also need a Japanese mobile phone number.

2. The Card:

After a few days (or instantly if you visit a kiosk), you will receive your Member IC Card. You also pay a small monthly membership fee (usually around 880 yen), but this fee typically gives you 880 yen worth of free driving credits, so it is essentially free if you drive once a month.

3. Booking:

Open the map on the app. Find a station near you. Click on a car icon. Select your start time and end time. Click “Reserve.” Done.

4. Unlock and Drive:

Go to the car. Touch your card to the “Touch” sensor on the rear window. The door locks click open.

Get in. Open the glovebox. You will see a key attached to a keyholder. Turn the keyholder to “Use” and pull the key out. Start the car.

5. The Fuel Card:

If you need gas, look in the sun visor. There is a credit card specific to that car. The manual in the glovebox will tell you which gas stations accept it (usually ENEOS, Idemitsu, etc.). Use that card to pay. It costs you nothing.

6. Return:

Park the car back in the exact same spot. Put the key back in the glovebox holder. Get out. Touch your card to the window sensor to lock it. The billing stops automatically.

Understanding the Costs: A Real World Example

Let’s look at the math to see how much this actually costs you.

Scenario A: The Grocery Run (Car Share)

• Time: 2 hours.
• Distance: 10 km.
• Vehicle: Compact Car (Honda Fit / Mazda Demio).
• Cost: Roughly 1,760 yen (880 yen per hour).
• Gas: 0 yen.
• Insurance: Included.
• Total: 1,760 yen.

Scenario B: The Day Trip to the Mountains (Rental Car)

• Time: 12 hours (8 AM to 8 PM).
• Distance: 200 km.
• Vehicle: Compact Car.
• Rental Fee: Approx. 6,000 yen (with web discount).
• Insurance (CDW): 1,100 yen.
• Gas: Approx. 2,000 yen (calculated at 160 yen/L and 15km/L efficiency).
• Total: 9,100 yen.

As you can see, for short trips, sharing is unbeatable. For longer days, rentals become competitive, especially when you factor in the distance charges that car sharing adds for long bookings.

Etiquette and Rules of the Road

Using a shared car involves a high level of trust. Japan functions on community responsibility, and car sharing is no exception.

The Cleanliness Rule:

There is no cleaning crew coming after you. If you eat chips, pick up the crumbs. If you drag mud in, shake out the mats. You must leave the car cleaner than you found it. Most cars come with a pack of wet wipes and a small trash bag in the trunk for this purpose. Never leave your trash in the car.

The 15-Minute Rule:

In car sharing, you can usually enter the car 10 to 15 minutes before your reservation starts to inspect it and adjust the mirrors. This time is often free. Use it to check for scratches. If you find a big scratch, you must call the center to report it before you drive, or you might be blamed for it.

The “Half Tank” Rule:

While you don’t have to fill up the car share, it is good manners to do so if the tank drops below half. As a reward, many companies give you a 30-minute discount on your next drive if you fill up the tank (detectable via the fuel card usage).

ETC Cards (The Toll Roads):

Japanese highways are expensive toll roads. You need an ETC (Electronic Toll Collection) card to pass through the gates smoothly and get discounts.

Most rental cars and shared cars have an ETC device (the machine that reads the card), but they do not provide the card itself. You should apply for your own personal ETC card through your credit card company and bring it with you every time you drive. Insert it into the machine, and the tolls will be billed to your personal credit card.

Navigating without Getting Lost

Most rental and shared cars come with a built-in GPS navigation system (Navi). The good news is that many modern ones have an English language setting.

However, the input method is often the hardest part. Entering Japanese addresses in English can be hit or miss.

The Pro Tip: Use the “Map Code” or “Phone Number” search.

Instead of typing the address of a restaurant, type its phone number. The GPS will find it instantly.

Alternatively, use Google Maps on your phone. Buy a cheap vent mount for your smartphone and bring it with you. Google Maps is often more up-to-date on traffic jams than the car’s onboard system.

Conclusion

The decision to forego car ownership in Japan does not mean giving up your freedom. In fact, it often means gaining financial freedom. By saving the thousands of dollars a year that would go into parking, taxes, and inspections, you have more budget to spend on the trips themselves.

The combination of a traditional rental for your big holidays and a car-sharing membership for your daily needs covers almost every scenario an expat faces. It allows you to drive a minivan when you have guests, a sports car when you want fun, and an eco-friendly compact for your shopping.

The roads of Japan are waiting. The coastlines of Izu, the mountains of Nagano, and the lakeside views of Fuji are all just a reservation away. So, get your license sorted, download the apps, and unlock the door to your next adventure.
