Cheap Super Discount Car Hire Deals at JR Shinjuku Station, Tokyo

When booking, check if the rental company offers extras such as GPS or child seats. These can enhance your driving experience but may incur additional costs, so it's wise to factor them into your budget.

Bring along your driver's license, ID, and credit card, as these are required for the rental.

Before renting a car, check if your personal car insurance covers rental losses. Many personal auto insurance policies and credit cards offer coverage for rentals, which could save you from extra insurance fees.

Select a pickup location that is convenient for you. Some rental companies offer locations within the airport for quick access, while others may require shuttle transportation.

If options at the station are limited, check for other rental agencies nearby that might offer better deals.

If sharing driving responsibilities, check the policies regarding additional drivers. Some companies charge fees for each extra driver, while others may include it for free under certain conditions.

Research fuel prices in the area where you'll return the vehicle. Filling up at a local station may be cheaper than paying for fuel through the rental company, especially if they charge higher rates.

To save on refueling costs when departing from JR Shinjuku Station, look for deals with a 'full to full' tank fuel policy, or even better, a free tank fuel policy, as opposed to a 'half-full to full' one.
