Ishigaki Rental Car | Insurance, CDW & NOC: How to Choose, Complete Guide

When you rent a car, you’re always asked, “Will you add collision (CDW) coverage? What about NOC coverage?” Many people hesitate, thinking, “It’s only a few thousand yen extra—do I need it?” But if an accident or trouble occurs, your out-of-pocket cost can differ by over ¥100,000 depending on whether you have coverage.

“What exactly is CDW coverage?” “How is it different from NOC coverage?” “Is it unnecessary if my credit card has insurance?” “What do I do if I crash?”—this complete guide clears up every question about rental car insurance.

In this article, we’ll fully cover how insurance and coverage work when renting a car in Ishigaki, how to choose, and our recommended plans.

The Three “Insurances/Coverages” of a Rental Car

1. Compulsory automobile liability insurance (mandatory)

This mandatory insurance comes automatically with every rental car. It basically covers bodily-injury accidents (up to around ¥30 million) and is included in the price, so no extra charge applies.

Compulsory insurance covers bodily-injury liability only. Property damage and your own injuries are not covered, so this alone is insufficient.

2. Voluntary insurance (included in the base price)

This is the voluntary insurance the rental company carries, covering bodily injury, property damage, the vehicle, and occupants. It too is included in the base price, so no extra charge applies, but in an accident a deductible (your out-of-pocket amount) arises.

Coverage item	Coverage details
Bodily-injury	Unlimited (on top of compulsory insurance)
Property damage	Unlimited (¥50,000 deductible)
Vehicle damage	Up to market value (¥50,000–150,000 deductible)
Occupant injury	Around ¥30 million

3. CDW coverage / NOC coverage (optional)

Optional coverage to reduce your out-of-pocket cost in an accident. This is the heart of today’s “how to choose.”

What Is CDW Coverage?

How it works

Coverage that makes your deductible (out-of-pocket amount) ¥0 even if you cause an accident. Without CDW coverage, you face out-of-pocket costs of about ¥50,000 for a property accident and ¥50,000–150,000 for a vehicle accident.

Item	Without CDW	With CDW
Out-of-pocket, property accident	Up to ¥50,000	¥0
Out-of-pocket, vehicle accident	Up to ¥150,000	¥0
Daily extra charge	None	¥1,000–1,500

Should you add CDW coverage?

Bottom line: strongly recommended. For an extra ¥1,000–1,500 per day, you avoid up to ¥150,000 out of pocket. Even for a 3-night, 4-day trip the extra is only about ¥5,000. Given the accident risk, there’s no reason not to add it.

Even if you’re fully confident in your driving, accidents can happen through the other party’s carelessness, so adding it gives peace of mind.

Cases not covered by CDW

• Accidents from drink-driving
• Driving without a license
• Driving by someone other than the contract holder
• Intentional accidents
• Theft / lost keys
• Accidents not reported to the police

What Is NOC Coverage?

How it works

NOC (Non-Operation Charge) = business-loss compensation. It covers the company’s inability to rent out the vehicle while it is being repaired after an accident.

Situation	Without NOC	With NOC
Accident, vehicle still drivable	¥20,000 out of pocket	¥0
Accident, vehicle not drivable	¥50,000 out of pocket	¥0
Daily extra charge	None	¥500–1,000

Should you add NOC coverage too?

Bottom line: recommended. With CDW alone, NOC (business-loss compensation) is billed separately. The full package of CDW + NOC gives peace of mind.

Whereas CDW covers “the vehicle’s repair cost,” NOC covers “the business loss during the repair period.” Only by adding both can a true ¥0 out-of-pocket be achieved.

Accident Risks Unique to Ishigaki

Animals darting out

On Ishigaki’s mountain roads, the crested serpent eagle, Yaeyama box turtle and coconut crab may cross the road. Take special care toward Mt. Omoto and Mt. Nosoko. Collisions with animals are covered.

Wildlife is especially active from evening into night. Slow down and drive safely.

Scratches on narrow roads

On the narrow roads of the town and remote islands, scratches to the side mirrors and body happen easily. Without CDW, even a minor scratch incurs an out-of-pocket cost.

The old town around Chorinji in particular has narrow lanes, so those unaccustomed to it face a high risk of scratches.

Vehicle damage on beaches and forest roads

On unpaved roads near beaches or at Shiraho Coast near the airport, underbody scrapes or salt-related damage can occur.

Salt damage from the reef

Bringing wet gear into the car after snorkeling risks salt damage. Cover seats with seat covers or waterproof sheets.

Placing a wet swimsuit or a sandy towel directly on the seat causes stains and mold. You may be charged a cleaning fee.

Flying debris from strong winds

Typhoon season brings the risk of scratches from flying debris. When a typhoon is forecast, avoid going out and move the car to a covered parking lot.

What to Do in an Accident or Trouble

1. Check for injuries; call an ambulance (119) if needed
2. Contact the police (110). An accident report is a prerequisite for coverage
3. Contact the rental company and follow their instructions
4. Exchange contact details with the other party (address, phone, insurer)
5. Photograph the accident scene
6. On the rental company’s instruction, move to a repair shop or arrange a replacement car

Note: failing to report to the police can void your CDW coverage. Always call the police if an accident occurs.

Points for Deciding on Coverage

Cases where you should definitely add it

• Not confident driving / a beginner
• First time using a rental car
• Planning to drive for long hours
• With children, where focus can scatter
• Driving at night or early morning
• Driving in an unfamiliar area
• Someone (other than the driver) plans to drink
• Driving an unfamiliar large vehicle

Check your credit card’s bundled insurance

Gold cards and above may come with bundled rental car insurance. Checking the deductible coverage range with your card company in advance helps you avoid double coverage.

However, card insurance often covers “your own damage only,” with liability to the other party separate. Combining it with the rental company’s coverage is safer.

Recommended Coverage Plans by Scenario

Couples / married trips

With a single driver, the full package is reassuring. An accident during a fun trip for two is damaging both emotionally and financially.

Family trips

With children in the car, attention tends to scatter. The full package plus an additional driver, so your spouse can also drive, gives peace of mind.

Friend groups

If you take turns driving, register all drivers plus the full package. Make sure coverage applies no matter who is driving.

Business use

An accident on business can become a company liability issue. Be sure to get the full package plus a receipt for expense reporting.

Driving Tips to Avoid Accidents

Obey speed limits

Ishigaki’s ordinary roads are 40–60 km/h. Don’t overspeed; drive with margin.

Watch for animals

Maintain a speed at which you can always slow down, ready for crested serpent eagles, goats, turtles and the like darting out.

Driving narrow roads

On the narrow roads of remote islands and the old town, drive with a “yield to oncoming cars” mindset. Reckless overtaking is strictly forbidden.

Refuel and use restrooms early

To avoid sudden trouble, manage fuel and your condition early. Facilities are limited in the north and on remote islands.

Never drink and drive

Okinawa has an awamori culture, but the driver must never drink. Violating this also voids CDW coverage.

FAQ on Rental Car Insurance

Is it OK without CDW coverage?

Unless you’re completely confident in your driving, it’s recommended. For ¥1,000 a day in premium, you avoid ¥150,000 out of pocket.

Is it unnecessary if I have credit card insurance?

Card insurance often covers only part of the deductible. NOC is frequently excluded, so using the rental company’s coverage as well is safer.

Is reporting to the police mandatory in an accident?

Yes, it’s mandatory. Handling an accident without calling the police causes trouble in later coverage procedures. Contact the police even for a single-vehicle accident.

Are scratches from flying stones or gravel covered?

With CDW coverage, they’re covered in many cases. Rules differ by company, so confirm at contract time.

What about theft?

Even with CDW, lost keys and theft are often excluded. Manage your keys carefully.

Can I add a driver midway?

Only drivers declared in advance are covered. To add a driver midway, always contact the rental company beforehand.

Is typhoon damage covered?

Natural disasters are often excluded. During a typhoon, move the car to a covered parking lot.

Can I take a rental car to the remote islands?

Rental cars cannot be brought to the main Yaeyama islands. You need to park at the Ishigaki Port Remote-Island Terminal and cross by ferry.

Is a replacement car provided after an accident?

Most companies arrange a replacement car, but it can take time in peak season. With NOC coverage, your priority for a replacement also rises.

Summary | For Ishigaki Rental Cars, the “CDW + NOC” Full Package Is Reassuring

You may think “the premium is a waste,” but the financial and emotional burden if you cause an accident is immeasurable. Even for 3 nights, 4 days the extra is ¥5,000–7,500. As peace-of-mind insurance, it’s by no means a costly expense.
