Iya Valley in western Tokushima rewards patient travelers with deep gorges, vine bridges and mountain scenery, but it is not a destination for rushing between pins on a map. A rental car gives you useful flexibility in Shikoku, yet the most important decision is to set a conservative plan before leaving Tokushima Awaodori Airport. Treat the journey as two different drives: first reach the Miyoshi/Awa-Ikeda area, then continue toward Oboke and the particular Iya sight you have chosen. This approach leaves time for navigation, fuel, weather checks and the slower rhythm of mountain roads.

Plan the journey in two stages

Miyoshi City’s official tourism guide lists the drive from Tokushima Airport to Awa-Ikeda at approximately one hour and 20 minutes, and the drive from Awa-Ikeda to Oboke at approximately 35 minutes. Those figures are useful planning references, not a promise for every destination in Iya Valley. Your final time changes with the exact accommodation or attraction, traffic, weather and road conditions. Enter the precise destination in the car navigation system before departure, keep a charged phone and ask the rental company how its navigation handles route changes.

Do not turn the published times into a tightly scheduled arrival. JNTO describes Iya as a remote mountain valley where narrow roads make travel slow. Build a daylight buffer, especially if this is your first experience of left-side driving or rural Japanese roads. If you have a lodging check-in, tell the property your realistic arrival window rather than planning a last-minute mountain ascent.

• Set the first navigation stop to Awa-Ikeda or Oboke, then confirm the second leg.
• Download or save the route while you have reliable signal at the airport.
• Check the day’s road and weather information before committing to side roads.

Choose the right destination for your confidence

Not every part of Iya is the same drive. The local IyaTime guide notes that the main route from Oboke to the Kazurabashi Vine Bridge is two lanes, comparatively wide and paved, although curvy and sometimes steep. Beyond that area, routes into Oku-Iya and hillside villages can include frequent one-lane sections. That distinction matters when choosing a car and an itinerary. A compact vehicle may feel easier to place on narrow roads, but the rental company should advise on vehicle availability and equipment rather than an online article making a promise.

For a first visit, pick one principal destination, allow time to park safely, and avoid adding remote side roads merely because they appear close on a map. At blind curves, use the roadside mirrors where provided, reduce speed and be prepared to wait. If another vehicle appears on a one-lane section, do not try to squeeze past beside a drop or rough edge; use a wider point to pass or reverse only when it is safe. Keep looking for people and cyclists because there may be no sidewalk or shoulder.

Apply Japan’s road rules throughout the drive

Mountain scenery does not change the basic rules. JAF states that drivers keep left, must yield to pedestrians, and must not use a phone or be distracted by navigation while driving. Everyone in the car must wear a seat belt, and a child younger than six must be secured in a child seat. Alcohol and driving do not mix: do not drive under the influence. Observe the posted limit rather than treating another vehicle’s speed as a guide. On any expressway section, JAF advises using the passing lane only to overtake and returning to the driving lane.

• Park only where stopping is permitted and the vehicle is fully clear of traffic.
• Pull over safely before changing a navigation destination or taking photographs.
• Keep fuel above a comfortable margin; do not assume a station will be nearby on mountain roads.

Weather and the return drive deserve equal attention

Check conditions again before leaving your final stop. IyaTime cautions that severe storms or typhoons can close roads and leave limited or no detours. In colder conditions, higher or remote routes can require different preparation; ask the rental company about suitable equipment and do not learn to drive on snow or ice on a steep unfamiliar road. If visibility, fatigue or weather makes the plan feel wrong, simplify it. Returning early is better than arriving after dark on a road you have not driven before.

A careful Iya Valley drive is still a rewarding one. Start with a valid driving document, a realistic two-stage plan, a vehicle you can handle confidently and enough time to respond to conditions. For the latest routing, closures and weather, consult local official information on the day rather than relying on any static itinerary.

Choose one lake, not an overfilled Hokkaido itinerary

Picking up a rental car at New Chitose Airport can make a first day in Hokkaido feel wonderfully open-ended. Lake Shikotsu is a sensible destination for travelers who want a calm introduction to driving rather than a long list of stops. It sits within Shikotsu-Toya National Park, a landscape shaped by volcanoes and rugged terrain. Japan National Tourism Organization guidance notes that transport between the park’s main areas is limited, and that a car is useful for reaching many places in the park. That is a reason to simplify your plan, not to try to see every area in one afternoon.

Make Lake Shikotsu the main destination. Leave Lake Toya, Noboribetsu, Jozankei, or a hiking trail for another properly planned day. This approach gives a new driver room to collect the car, understand the navigation unit, take breaks, and return before the day feels rushed. It also avoids treating a national-park map as though every attraction were a quick hop from the next.

Start at the airport with a short, deliberate routine

Before leaving the rental location, set a quiet ten minutes aside for the practical details. Confirm the fuel type, check the car for any existing marks, ask how to use the navigation system, and agree on who is driving. Load your Lake Shikotsu destination while you are parked rather than while the car is moving. If the car has driver-assistance functions, learn the essentials before joining traffic; they support attention, but do not replace it.

• Keep your licence, required driving documents, rental agreement, and emergency contact information where the driver can reach them without searching.
• Set the navigation, mirrors, seat position, and climate controls before departure.
• Choose a return time with daylight and a fuel stop in mind, then treat extra sightseeing as optional.

JNTO lists a bus journey of about 55 minutes from New Chitose Airport to the Lake Shikotsu bus terminal. A rental-car journey should not be judged against that timetable: collection time, weather, traffic, rest stops, and your own familiarity with the car all matter. Use your navigation system and current road information on the day, and build a margin rather than promising a fixed arrival time.

Drive by Japanese road rules, not by holiday momentum

The first adjustment for many visitors is simple but important: vehicles drive on the left in Japan. The Japan Automobile Federation (JAF) also says drivers must yield to pedestrians, everyone in the vehicle must use a seat belt, and a child under six must be secured in a child seat. Alcohol and driving do not mix. Keep your phone out of your hand and do not let the navigation screen compete with the road.

• Follow every posted limit and road instruction. JAF states that, where no limit is signed or marked, the default for regular cars is 60 km/h on ordinary roads and 100 km/h on expressways.
• Approach crossings, junctions, and parking areas patiently, expecting people on foot and unfamiliar traffic patterns.
• If visibility, rain, fatigue, or an unfamiliar road makes the drive feel demanding, slow down or pause. A scenic day has no prize for arriving first.

Let the lakeside set the pace

Once you arrive, keep the plan modest: enjoy the lake view, take a short walk where access is permitted, use a rest area when needed, and check the time before adding another stop. Shikotsu-Toya National Park contains varied terrain, so a map pin is not a guarantee that every nearby-looking activity fits today’s schedule. Do not rely on a past blog, a seasonal photograph, or an old map for current access conditions. Check current notices before choosing any side trip or trail.

This slower approach is especially valuable for a first drive after a flight. It makes space for navigation errors without turning them into stress, and it lets the group decide whether the weather and energy level suit more time outdoors. If they do not, the lake itself is still a complete destination.

Return with the same care you used to start

Before leaving the lakeside, set the return route while parked and make a quick group check: driver alertness, fuel level, weather, and rental return time. If another driver is permitted under your rental agreement, change drivers only after stopping safely and completing any required registration. On the way back, keep the driving lane unless overtaking and refuel early if the gauge calls for it; JAF notes that some expressway stretches have long gaps without service stations.

A Lake Shikotsu rental-car day works best when it remains intentionally small. With one clear destination, current information, and respect for Japan’s road rules, your first Hokkaido drive can be both practical and memorable.

Start with a realistic first drive

Landing at Kagoshima Airport puts a rental-car trip within reach of the Kirishima area, but it is worth treating the first leg as a gentle introduction to southern Kyushu rather than a race to fit in every stop. Kirishima Jingu Shrine sits in Kirishima City on the slopes of Mt. Kirishima, and the surrounding landscape changes from airport roads to greener, more elevated terrain. Japan’s National Parks site notes that a car makes it easier to reach places and trailheads beyond the more frequently served routes in Kirishima-Kinkowan National Park. That flexibility is valuable only when you leave enough time to use it safely.

Prepare before the wheels start turning

Do the unglamorous jobs while you are still in the rental-car area. Adjust the seat, mirrors and steering wheel; confirm the parking-brake operation; and find the controls for headlights, wipers, hazard lights and demisters. If the navigation system is unfamiliar, ask the counter staff how to enter a destination before you drive away. Save the shrine’s name, address and a second safe destination such as your accommodation or a fuel station. Keeping these details ready avoids looking down at a phone on an unfamiliar road.

• Check that every person who may drive is registered on the rental agreement.
• Keep your licence documents, rental contact number and booking details together but not loose in the cabin.
• Set navigation and music before departure, then use a passenger for changes where possible.
• Start with a conservative plan that leaves room for a rest stop, a wrong turn or changing weather.

Use the airport route as a confidence-building drive

Kirishima Jingu’s official access information lists driving from the Mizobe-Kagoshima Airport interchange as one of the approaches to the shrine. That is useful direction, but it does not replace current navigation. Follow posted signs, obey the indicated speed and drive on the left. On an unfamiliar mountain-side approach, avoid trying to make up time after a slow section. Brake before a bend, look through the curve, and leave a gap that lets you stop comfortably if traffic slows. If rain, mist or darkness reduces what you can see, slow down further and reconsider an optional stop rather than pressing on.

Plan your fuel with the return journey in mind. A compact itinerary is easier to manage when you know where you intend to refuel and when you must return the car. Do not assume that a scenic road will have the services you expect at the moment you need them. A quick check of the fuel gauge and your return agreement before setting out can prevent a stressful final hour.

Arrive without turning parking into pressure

The shrine’s official access page states that it has free parking for 500 cars. That capacity is helpful, not a guarantee of a space at a particular time. Approach slowly, follow on-site staff and signs, and park only in marked areas. Do not stop in a lane to rearrange bags or decide on your next destination. Once parked, note where you left the car and make sure the doors are locked; take valuables with you rather than leaving them on display.

Give the visit its own time instead of treating it as a photo stop between long drives. The official site says the grounds are open for worship, while reception for prayers and the granting office run from 8:00 to 17:00. If your visit depends on a particular service, confirm the latest details directly with the shrine rather than relying on an old travel post.

Choose an autumn plan that remains flexible

Kagoshima’s official tourism information places the typical best period for autumn leaves at Kirishima Jingu from late November into December. That is a seasonal guide, not a day-by-day forecast. Book accommodation and a rental car early for popular periods, but keep the sequence of minor stops flexible. Clear mountain views can change quickly, and the best decision may be to enjoy one destination unhurriedly rather than drive farther merely because it appeared on an itinerary.

For a relaxed first day, the winning plan is simple: collect the car carefully, leave with a charged phone and navigation ready, drive at a pace suited to the conditions, park legally, and preserve enough time for the return. Kirishima rewards a rental-car traveller who treats mobility as freedom to slow down.

Roundabouts can feel unfamiliar when you are driving a rental car in Japan for the first time. A Japanese roundabout is a signed circular intersection in which vehicles travel clockwise. Before you reach the entry, set your route, identify the exit you need, and give yourself time to read the signs. The aim is not to hurry through. Follow the road markings, look well beyond the bonnet, and make every movement predictable for the people sharing the road.

Recognize the traffic pattern before you enter

Japan drives on the left, and this matters at a roundabout. The official guidance explains that a driver should move as close as practical to the left edge before entering and proceed at a reduced speed. As you approach, look for the roundabout sign, the circulating roadway, approaching pedestrians, and the vehicles already travelling around the circle. Reduce speed early rather than braking abruptly at the entrance. This gives you time to decide whether the space is clear and to respond calmly if someone is crossing nearby.

Do not assume that an open-looking entrance gives you priority. Traffic already circulating in the roundabout has priority, so wait when entering would obstruct it. This is especially important in a rental car, when the driving position, mirrors, or navigation instructions may still feel new. Keep a comfortable gap, enter only when you can do so smoothly, and avoid forcing another driver to brake or change course.

Use a simple entry routine

• Move toward the left side of the approach and slow down before the entry.
• Check the circular roadway for traffic that is already moving through it.
• Check the crossing area and the immediate roadside for pedestrians.
• Enter only when your path is clear, then continue clockwise at a safe, controlled speed.

This routine is deliberately short. It helps a visitor avoid trying to read a map, choose an exit, and judge a gap at the same moment. If your navigation instruction is unclear, let the road situation come first. Continue around only while it is safe to do so, and take the exit when you can make the manoeuvre without sudden steering or braking.

Signal left when your exit is next

The exit signal is a key detail. When you pass the exit immediately before the one you plan to take, operate the left turn signal and keep it on until you leave the roundabout. If you will take the first exit immediately after entering, use the left signal as you enter and continue it until you have exited. This clear signal helps the driver waiting to enter understand your intention. Keep your speed low through the exit and stay alert for people crossing at or close to the roundabout.

Make space for pedestrians and local conditions

Official police guidance specifically calls on drivers to watch for pedestrians crossing at the roundabout or in its immediate vicinity, both when entering and while circulating. Treat this as an active observation, not a quick glance. In rain, darkness, or an unfamiliar neighbourhood, reduce speed further and allow extra time for visibility and decision-making. Never let a spoken navigation instruction override a sign, a pedestrian, or the actual traffic situation.

Roundabout layouts, signs, and lane markings can vary, so the on-site signs and conditions always control your next action. The reliable habits remain the same: approach from the left, slow down, yield to traffic already in the circle, signal left before your exit, and scan carefully for pedestrians. Review these steps before collecting your rental car, and a signed roundabout can become a calm, predictable part of your Japan drive.
