Renting a car in Japan gives you ultimate freedom, but eventually, the fuel gauge will hit empty. For many foreign tourists, pulling into a Japanese gas station (ガソリンスタンド - Gasorin Sutando) is a highly stressful experience. The pumps are covered in complex Kanji, the machines shout instructions at you, and the payment process is often unintuitive.
Whether you pull into a full-service station where attendants aggressively wash your windows, or a self-service station where you must navigate touchscreens alone, this guide will teach you exactly how to fill your tank without putting diesel into a petrol engine.
1. Self-Service vs. Full-Service
As you approach a gas station, look for large Kanji signs to determine the type of station:
- セルフ (Serufu): Self-Service. You pump the gas and navigate the touchscreen yourself. These are cheaper and increasingly common.
- フル (Furu) or no sign: Full-Service. You stay in your car. Attendants will guide you in, pump the gas, wash your windshield, and take your payment through the window.
2. Choosing the Right Fuel (Color Codes)
This is the most critical step. Putting the wrong fuel in your rental car will destroy the engine and cost you hundreds of thousands of yen in liability. Japanese pumps use a universal, strict color-coding system:
| Nozzle Color | Japanese Name | Meaning |
|---|---|---|
| Red Nozzle | レギュラー (Regular) | Regular Unleaded Petrol. 95% of standard rental cars (Toyota Vitz, Aqua, Corolla) use this. |
| Yellow Nozzle | ハイオク (High Octane) | Premium Unleaded Petrol. Required for luxury or sports cars. |
| Green Nozzle | 軽油 (Keiyu) | Diesel. Used for large vans (Toyota HiAce) or trucks. Do not confuse "Keiyu" with K-cars (Kei jidosha). K-cars use RED regular gas. |
3. Navigating the Self-Service Touchscreen
If you are at a self-service station, the touchscreen will speak to you in Japanese. Follow these basic steps:
- Select Payment Method: The screen will ask how you want to pay. Press 現金 (Cash) or クレジットカード (Credit Card). If paying cash, insert your bills (e.g., 5,000 JPY) into the machine now.
- Select Fuel Type: Tap the Red Button for Regular (レギュラー).
- Select Amount: You can choose by Yen amount (e.g., 3,000 Yen), by Liters (e.g., 20L), or simply press 満タン (Mantan - Full Tank). If returning a rental car, you MUST choose Mantan.
- Static Discharge: The machine will beep and ask you to touch a black anti-static pad (静電気除去シート) before grabbing the nozzle to prevent fires.
- Pump: Pump the gas. If you paid cash and chose Mantan, you will receive a receipt with a barcode. Take this receipt to the separate change machine (Seisanki) nearby to get your change.
4. The Full-Service Experience
If you pull into a full-service station, roll down your window. The attendant will shout "Irasshaimase!" (Welcome). All you need to say is two words:
"Regular, Mantan, please."
The attendant will fill the tank, wipe your windows, and bring a credit card reader or a cash tray to your window. When you drive away, they will often bow and guide you safely into traffic.
⚠️ Keep Your Final Receipt
When returning a rental car in Japan, the agency requires you to return it with a full tank. You must present the physical gas receipt to prove that you filled up at a station within a 5km radius of the rental office just before returning it.
Ready to Hit the Road?
Pumping gas is easy once you know the colors. But getting the rental car requires the right legal documents. If your license is from France, Germany, Switzerland, Belgium, Monaco, Taiwan, or Estonia, you cannot drive without an Official JAF Translation.
