Rental-car application
Review These Terms Before Requesting a KAISEI Rental Car
KAISEI offers an in-house rental-car service for guests staying at KAISEI properties. You may submit a request to pick up or return a vehicle at a Tokyo airport, major station, Tokyo hotel, or KAISEI property. A rental is not confirmed until your stay is verified through a booking platform or in writing by KAISEI, and KAISEI has confirmed in writing your driving eligibility, insurance, vehicle availability, pickup and return locations, fees, deposit, and payment terms.
Important: submitting the website form is an application and does not mean that a vehicle has been confirmed. Do not treat the vehicle arrangement as part of a confirmed itinerary until written confirmation has been received from KAISEI.
Online application
Send the complete rental-car request in one message so KAISEI can confirm it quickly.
This form creates a structured message that can be sent to KAISEI by WhatsApp or email. It is an application, not an instant confirmation. KAISEI will reply with vehicle availability, the final price, insurance, deposit, driver-document verification and payment instructions.
When your rental is confirmed
Submitting the website form starts the rental review process but does not confirm a vehicle.
Accommodation booking and rental-car arrangements are separate services. A room inquiry, hotel booking, booking-platform confirmation or website form submission does not automatically reserve a vehicle. KAISEI will confirm the rental car separately through LINE, WhatsApp, email or a formal confirmation document.
Road trips in Ibaraki
This service is primarily for guests staying at KAISEI properties who need vehicle pick-up and return arrangements at an airport, station, Tokyo hotel or KAISEI property.
Driving eligibility is not approved automatically
KAISEI does not confirm that a guest is legally permitted to drive in Japan until the required documents have been verified. Driving eligibility is reviewed under Japanese law, the applicable insurance conditions and KAISEI's rental-car rules.
Driving eligibility
Guests must demonstrate that they are legally permitted to drive in Japan.
KAISEI operating rule: all driver documents must be checked before confirmation, and the originals must be checked again when the vehicle is handed over. A photo check is only a preliminary review and does not replace inspection of the original documents.
Accepted licensing basisA Japanese driver's license, an International Driving Permit in the 1949 Geneva Convention format, or a foreign driver's license from an eligible country or region with an accepted Japanese translation
In general, drivers must hold a valid Japanese driver's license, an International Driving Permit in the 1949 Geneva Convention format, or, where permitted by Japanese law, a foreign driver's license from an eligible country or region together with an accepted Japanese translation. According to 2026 information from Japan's National Police Agency, these foreign licenses mainly include those issued by Switzerland, Germany, France, Belgium, Monaco and Taiwan. The latest official Japanese rules always take precedence.
Required documentsOriginal passport and driver's license documents may be required
Guests should prepare their passport, original driver's license, valid International Driving Permit or accepted Japanese translation, proof of the date of entry into Japan when required, booking name, telephone number and driver age details.
International Driving Permit restrictionsVerify the validity period and applicable conditions
The permitted driving period and document validity depend on the issue date, date of entry into Japan, document expiry date, residence status and re-entry conditions. KAISEI cannot verify driving eligibility from photographs alone.
Japanese translationNot every foreign driver's license can be used in Japan with a Japanese translation
A Japanese translation is valid only for driver's licenses from countries or regions recognized under Japanese law, and it must be issued by an accepted body such as a consular authority, JAF or another organization recognized by the Japanese authorities. JAF does not translate International Driving Permits. Confirm translation times, fees, paper-document requirements, and eligibility before travel.
KAISEI operating rulesKAISEI may set risk-control requirements that are stricter than the legal minimum
Based on operational risk, KAISEI may set requirements relating to age, driving experience, permitted vehicle class, deposit, credit card, language and supporting documents.
Refusal to hand over a vehicleService may be refused if driving eligibility cannot be verified
KAISEI may refuse to hand over a vehicle or may cancel the rental if documents are incomplete, expired, inconsistent, illegible or unacceptable to KAISEI, the insurer or under applicable law.
KAISEI service standard
The following fees and conditions will be stated in the written confirmation.

The standard application lead time is at least 48 hours. For airport delivery, night-time delivery, child seats, larger vehicles, peak periods or verification of a foreign driver's license, applying at least 72 hours in advance is recommended.

Waiting feeReference waiting fee: JPY 500-1,500 per 10-15 minutes
A 15-minute free waiting period is recommended. After that, a waiting fee may apply or the handover may be moved to paid parking. Please notify KAISEI of flight or train delays as early as possible.

Application and confirmation process
Add the rental-car arrangement to your itinerary only after the vehicle has been confirmed.
Guest submits requirements
The guest provides the accommodation, dates, pick-up location, return location, number of passengers, amount of luggage, driver documents, preferred vehicle class, child-seat requirements and expected arrival time.

Guest accepts in writing
The guest confirms acceptance in writing, provides the required documents, accepts KAISEI's rental-car rules and completes the required payment or deposit process.
Final confirmation
The rental becomes effective only when written confirmation has been received from KAISEI. Confirmation of an accommodation booking does not confirm a rental car.
Vehicle handover inspection
At pick-up, the driver's identity, original documents, vehicle condition, fuel level, mileage, equipment, emergency contact details and return rules must be checked.
Vehicle pick-up and return
Vehicle delivery can be arranged only when the location, time, personnel and vehicle conditions all match.

Before selecting a vehicle class, confirm the number of passengers, luggage size, child seats, winter equipment, elderly passengers and the dimensions of the property's parking space.
Fees and payment
Review the complete fee structure before final confirmation.
Your written quote will itemize the basic rental fee, vehicle-delivery fee, optional equipment, insurance or waiver charges, deposit, cancellation charges, and any post-rental settlement items.
Basic rental price
The vehicle class, rental period, season, weekend, public holiday, pick-up time and return time may all affect the basic price.

Costs incurred during use
Guests may be charged for fuel, tolls, parking, traffic fines, towing, late return, excessive cleaning, lost items and losses not covered by insurance.
Prices may change before confirmation
All prices shown before written confirmation are estimates. The final charges are subject to KAISEI's confirmation and the guest's acceptance.
Insurance and liability
Before driving, guests must clearly understand the insurance cover and their own financial responsibility.
KAISEI's written confirmation will identify the basic motor insurance included in the rental plan. Overseas guests are strongly encouraged to choose a Collision Damage Waiver (CDW) and, where available, an NOC waiver for loss-of-use charges.
Basic insuranceBasic motor insurance
Recommended reference cover: unlimited third-party bodily-injury liability, third-party property-damage cover with a deductible, vehicle-damage cover with a deductible appropriate to the vehicle value, and passenger injury protection. The specific terms must follow KAISEI's actual insurance policy documents.
DeductibleReference deductible: JPY 50,000-100,000 for each applicable accident category
Common market reference: the third-party property-damage deductible is approximately JPY 50,000; the vehicle-damage deductible is approximately JPY 50,000 for a standard vehicle and may reach JPY 100,000 for a larger or special vehicle.
CDWA deductible waiver is recommended as a standard option
Reference fee: approximately JPY 1,100-2,200 per 24 hours. KAISEI strongly recommends CDW for overseas guests. Availability depends on the actual insurance plan.
NOCLoss-of-use charges must be explained separately
Common market reference: where the vehicle can be driven back, the NOC is usually approximately JPY 20,000-30,000. Where it cannot be driven back, the NOC is approximately JPY 50,000-70,000 or more, depending on the vehicle class.
NOC waiverA protection package including an NOC waiver is recommended
Reference fee: approximately JPY 550-1,100 per 24 hours when sold separately, or approximately JPY 1,650-3,300 per 24 hours when packaged with CDW and more comprehensive support. This is KAISEI's recommended protection option where available.
ExclusionsInsurance does not cover every situation
Driving under the influence of alcohol or drugs, an unauthorized driver, an invalid license, dangerous driving, traffic violations, off-road use, failure to report an accident, using the wrong fuel, lost keys, interior damage, and tyre or wheel damage may be excluded from insurance cover.
authorized driversOnly approved drivers may drive the vehicle
Every driver must be registered and approved in writing by KAISEI before driving. Allowing an unregistered person to drive may invalidate the insurance and create liability for the guest.
Liability for damageThe guest may be responsible for deductibles or losses that are not covered
The guest may be charged for vehicle damage, third-party damage, theft, loss, loss of use, towing, cleaning, smoking damage, pet damage and traffic fines under KAISEI's rental-car rules and the applicable insurance conditions.
KAISEI's roleKAISEI operates the rental-car service but does not replace the insurer
KAISEI is responsible for reservations, vehicle handover, guest communication and operational support. Insurance coverage decisions, exclusions and claim amounts are governed by the actual insurance contract and the required accident procedures.
Written recordsKeep all confirmation records
Keep the rental agreement, insurance summary, emergency contacts, payment receipts, pickup and return photographs, and any accident documentation.
Accidents, breakdowns and violations
If an accident occurs, safety and official reporting take priority.
Contact emergency services first when required, then contact KAISEI for translation and coordination support. Police, medical services, insurers, and legal procedures take priority.
Stop in a safe place and assist anyone who is injured
Where conditions allow, move to a safe location to prevent a secondary accident, call emergency medical services when necessary, and follow Japanese law and police instructions.
Report the accident to the police
A police report is essential for the accident record and insurance process. Do not reach a private settlement without completing the required procedures.
Contact KAISEI immediately
After completing the emergency and police-reporting steps, follow KAISEI's instructions for the accident, breakdown, towing, replacement vehicle, insurance claim and vehicle-return process. KAISEI emergency contact in Japan:070-2298-9860.
Record the facts carefully
Where it is safe and lawful to do so, take photographs and collect the other party's details, vehicle details, insurance details, accident location, witness information and dashcam or other driving records.
The driver is responsible for traffic fines and violations
Parking violations, speeding, toll-road violations and other penalties must be handled by the driver in accordance with Japanese law and KAISEI's rental-car rules.
First point of contact and translation support
KAISEI can assist with translation, contacting the insurer, coordinating towing, arranging vehicle return and supporting guest communication. KAISEI cannot replace police reporting, medical care, an insurance investigation or the driver's legal responsibility.

Weather or disruptionSafety may take priority over the original itinerary
Typhoons, snow, disasters, flight delays, train disruption, road closures, operational staffing constraints or vehicle breakdowns may require rescheduling, a replacement vehicle or cancellation.
