After an international flight, the best first day with a rental car is rarely the longest one. A simple drive from Narita toward Chiba’s Kujukuri Beach gives you room to get comfortable with the vehicle, practise Japan’s road rhythm, and enjoy the Pacific coast without trying to race across a whole region. Treat this as a flexible first-day plan rather than a fixed timetable: your exact route, road conditions, weather and parking options should be checked on the day you travel.

Choose one part of the coast, not the whole coast

Narita Airport and Kujukuri Beach are both in Chiba Prefecture. The Japan National Tourism Organization describes Kujukuri as a 66-kilometre stretch of sandy coastline, so it is better approached as a long coastal area than as one tiny stop. Pick one beach area or one designated parking point as your main destination, then decide whether you have the energy for a second stop after you arrive. This keeps a first drive manageable after check-in, luggage collection and vehicle handover.

Chiba’s official tourism site also presents a much longer coastal driving course that continues toward Choshi. That is useful inspiration, but it is not a reason to copy every stop on arrival day. A relaxed plan has a clear finish: park, take a walk, have a meal or drink, and return before you become tired.

Set up before leaving the airport area

Use the handover time to make the car familiar rather than rushing straight onto the road. Ask where the fuel level is shown, confirm the navigation language if an option is available, and save your destination by its official name or map pin. A screenshot of the return location and the rental company’s contact details can also prevent stress later. Put luggage securely away before moving off, and choose a first destination that does not require constant last-minute lane changes.

• Set one primary parking destination before you start driving.
• Keep a backup stop in case a car park is full or the weather changes.
• Bring water, especially on warm days, and allow time to rest after parking.
• Check the forecast and local notices before heading to the shore.

Use the first kilometres to reset your driving habits

Japan drives on the left. The Japan Automobile Federation also reminds drivers to yield to pedestrians, so approach crossings and turns with patience rather than assuming that a clear-looking road will stay clear. Keep your eyes on signs, signals and road markings, and follow the posted limit rather than relying on a speed from another country. At a railway crossing, slow down early, observe the signals and complete the crossing only when it is safe.

Do not let a navigation prompt make you force a turn. If you miss one, continue safely and let the route recalculate. This is particularly helpful around unfamiliar junctions, narrow local streets and busy beach approaches. A calm detour is always better than a sudden manoeuvre.

Park for the place you are visiting

Use a designated public or private car park for the specific beach, café or attraction you choose. Kujukuri Town, for example, operates a municipal coastal car park for public use, but availability, rules and seasonal arrangements can differ by location. Read the signs at the actual car park, note any payment method, and never assume that a roadside space or sandy access is suitable for a rental vehicle. Before walking away, lock the car and take valuables with you.

Let summer conditions set the pace

On hot days, a coast can feel cooler than it really is. Before leaving, look at the day’s weather and heat-risk information, and make water and rest part of the itinerary. The Ministry of the Environment publishes heat-illness and WBGT guidance for Japan. If heavy rain, strong wind or a heat alert changes the day, shorten the plan instead of trying to “make up” missed sightseeing. The coast will still be there on another day.

Finish with an easy return

Build a simple return into the plan: decide your latest comfortable departure time, check fuel and parking receipts if your rental agreement requires them, and avoid starting a long drive when everyone is already tired. A Narita-to-Kujukuri outing works best when the goal is confidence, not mileage. With one well-chosen stop, careful parking and patient driving, your first day can become a gentle introduction to self-driving in Chiba.
