If you are renting a car and planning an expressway, ETC is the card that sits in the car’s onboard unit — not a foreign credit card you tap at the booth, and not something JapanTolls sells.
JapanTolls is an independent estimator. It is not NEXCO East, Central, or West. Confirm live rules with the operator and your rental desk.
What ETC is, and why cash lanes are a poor backup
ETC (Electronic Toll Collection) is Japan’s wireless expressway payment. A Japanese ETC card in a fitted onboard unit talks to the plaza as you pass. DrivePlaza’s visitor pages treat this as the normal way to pay on NEXCO roads: the unit is in most rental cars, and the card is a separate piece you have to request.
Without ETC you use a general lane (一般). At entry you take a paper ticket; at exit you stop and pay in yen cash or, where the plaza still takes it, a credit card. That is slower, and it is not available everywhere.
Smart ICs are interchanges built for ETC only. NEXCO Central is explicit: no cash, no credit card, no highway card. If your trip uses a Smart IC — and many rural or rest-area ramps do — a cash plan simply cannot enter or leave there.
A growing number of ordinary plazas are also ETC-only, with a “Support” or “ETC/Support” lane if you enter by mistake. Cash is not gone nationwide in 2026, but treating general lanes as always there is already a bad plan.
How a visitor actually gets ETC
JapanTolls does not rent or sell ETC cards. Short-term visitors almost never apply for a resident card through a Japanese issuer; that product assumes an address and a credit contract in Japan.
The usual path is the rental car. DrivePlaza tells visitors to check with the rental company for a car that already has the onboard unit and an ETC card. japan-guide notes that some rental companies offer ETC cards for a small fee, and recommends them if you will use expressways. Ask when you book, not only at pickup — busy airport desks (Narita, Haneda, Kansai) can run out of cards even when the car has a unit.
There is no reliable public NEXCO vending machine that hands a tourist a personal ETC card for the week. If a desk at the airport offers a card, it is still the rental company’s card, billed through the rental.
Card rental fees are set by the company, not by NEXCO, and they change. We do not quote a yen figure here. Tolls you actually drive are a separate charge, almost always settled when you return the car.
At the booth, with and without the card
Insert the card fully into the onboard unit before you leave the lot. NEXCO’s usage notes: an uninserted or expired card means the bar stays down. You should hear or see a recognition prompt when the ignition is on.
With a working card, take a lane marked ETC or ETC/一般. Slow to under 20 km/h, keep a gap, and go only after the bar lifts. Do not reverse if it stays closed — wait, use the intercom, and follow staff. At Smart ICs the sequence is different: you stop first, then the bar opens after the unit talks to the gate.
Without a card, stay out of purple ETC-only lanes. Use 一般 / General, take the ticket in, pay out. You cannot use a Smart IC. If you roll into an ETC-only plaza by mistake, NEXCO East and West tell you to proceed to a Support lane, stop, and follow the attendant — still do not reverse.
Handing the card back with the car
The card belongs to the rental company. Return it with the keys. Staff read the card (or their backend) and add expressway tolls to the rental bill. Pay that bill the way you pay the car — often a credit card on file.
Leave the card in the unit while you drive so you do not forget it at a rest stop. NEXCO West also tells drivers to take the card with them when they leave a parked car, to limit theft. Follow the desk’s return checklist so a missing card does not become a replacement charge.
Ordinary car vs kei
ETC hardware does not change for a kei rental. You still need the onboard unit and a valid card. What changes is the toll class of the vehicle.
NEXCO bills five classes. Kei cars sit in 軽自動車等 (light vehicles), a cheaper class than 普通車 (ordinary passenger cars). Motorcycles share that light class. Ask the rental desk which class they booked, then use the same class in the calculator. The card does not pick the class; the car does.
Cashless plans through fiscal 2030
In December 2020, MLIT and the expressway companies published a roadmap to make plazas cashless by shifting them to ETC-only: cities first, then the rest of the country around fiscal 2030 (the Japanese fiscal year that ends in March 2031). That target is still the one operators cite in 2026, and conversions are already live — NEXCO West, for example, keeps adding ETC-only gates and support lanes.
This is a multi-year conversion, not a sudden cash ban. Many plazas still have general lanes today. The practical visitor move is still a rental ETC card, so Smart ICs and converted plazas are not a surprise.
Frequently asked questions
Can a tourist get an ETC card in Japan?
Usually yes, by requesting one with a rental car that already has an onboard unit. Ask when you book. JapanTolls does not sell cards, and a same-week resident ETC application is not a realistic tourist path.
Is cash still OK on Japanese expressways in 2026?
At many ordinary plazas, general lanes still take a ticket and yen (sometimes a credit card). Smart ICs never do, and a growing list of plazas are ETC-only. Cash is a backup, not a plan.
What if I enter an ETC-only lane without a card?
Do not reverse. NEXCO tells you to use a Support or ETC/Support lane, stop, and follow staff. You will still owe the toll; you just will not get a clean ETC pass.
Does a kei car change ETC?
The card and the unit work the same. NEXCO charges kei cars in the cheaper light-vehicle class, not as ordinary cars. Confirm the class with the rental desk.
When do I pay the tolls?
With a rental ETC card, the company typically adds the expressway charges when you return the car and the card together. You do not feed cash into the ETC unit.
