Summer Road Trip from Higashimiyoshi: Iya Valley and Kagawa by Rental Car
Quick answer: A rental car is a useful way for international visitors to explore Iya Valley, Oboke and parts of Kagawa from Higashimiyoshi. Plan Iya and Oboke as one mountain-road day, then choose one Kagawa area for a separate day. Before booking, confirm that every driver has original documents that are legally valid for driving in Japan.
Mikamo Rent-a-Car is located at 5562-1 Kamo, Higashimiyoshi, Tokushima, on the same site as ENEOS Mikamo Service Station. The location makes it possible to pick up a car near western Tokushima, refuel on the same site before returning it, and travel in two different directions without starting in a large city.
Who this road-trip plan is for
This guide is designed for international travelers, exchange students, university friends and small groups who want more freedom than a fixed bus timetable can provide. It is especially useful when you have suitcases, want to stop for scenery, or plan to visit places that are far from a railway station.
A rental car is not automatically the best option for everyone. If no one is comfortable driving on the left side, on narrow mountain roads or in summer weather, use official bus, train, taxi or tour information instead. A safe, shorter plan is better than a long list of places.
Day 1: Iya Valley and Oboke
Check the official tourism and road information first
Use the official Oboke-Iya tourism website to choose a small number of stops and check current notices, weather and access information. Mountain conditions may be different from the weather at your hotel or pickup location.
Drive during daylight when possible
Iya has narrow sections, curves, slopes and places where two vehicles cannot pass at the same time. Put the most experienced driver in the first mountain section. Slow down before a curve, look far ahead for a passing place, and do not speed up simply because another car is behind you.
Choose two main stops, such as an Oboke area stop and one Iya destination. Keep one optional stop only if the weather, road and return time remain comfortable. This article does not guarantee that any particular road or attraction is open.
Day 2: Choose one area in Kagawa
Do not combine every famous place in one day
Kotohira, Mitoyo and Takamatsu offer different experiences and are not one compact sightseeing area. Decide whether your main interest is a shrine and town walk, Seto Inland Sea scenery, udon, art or city sightseeing. Then group nearby stops.
Check opening days, parking and events on the official Visit Kagawa website. Popular restaurants and sunset locations may add waiting time. Set a time to leave your final stop, rather than waiting until your rental-car return deadline feels close.
Driving documents for visitors to Japan
Japan does not accept every foreign license or every document called an “international driving license.” According to Japan’s National Police Agency, a driver generally needs one of the following:
- a valid Japanese driver’s license;
- an original International Driving Permit in the form prescribed by the 1949 Geneva Convention, together with the required original documents; or
- for a limited list of countries and regions, the original foreign license with an authorized Japanese translation.
A digital or smartphone-only International Driving Permit is not valid in Japan. Rules also involve the issue date, date of entry into Japan and permitted vehicle category. Read the National Police Agency guidance for foreign license holders and ask the rental office before booking. Do not wait until pickup to discover that a document cannot be accepted.
Send document details before booking
Tell the rental office the country or region that issued each driver’s license, which original documents each person will carry, and the arrival date in Japan. A photo can help with a preliminary check, but every required original document must still be presented at pickup.
Every person who may drive should be declared and checked before departure. Do not let an unregistered friend drive because the registered driver becomes tired. If one person’s documents are not valid, make the trip plan work with the drivers who are legally accepted.
Choose the car by people and luggage
A small car can be easier on narrow roads, but it may not hold four people and four large suitcases safely. A large vehicle can carry more luggage, but a driver with little experience may find it harder on mountain roads. Tell the staff both the number of passengers and the number and approximate size of bags.
| Group | What to discuss |
|---|---|
| Two or three people, light bags | Kei or compact-car availability |
| Four or five people, travel luggage | Rear-seat comfort and luggage space |
| Larger group | Minivan availability and driver experience |
Navigation and ETC equipment are available, but do not assume that an ETC card, tolls, fuel or optional equipment is included. Confirm the exact booking conditions.
Pickup and shuttle information
Mikamo Rent-a-Car can arrange a free shuttle from Awa-Kamo Station or Yoshinogawa Highway Oasis. After 5:00 p.m., shuttle service is limited to those two locations. A shuttle must be arranged in advance; it is not an on-demand service that is guaranteed without a booking.
At pickup, confirm the return time, fuel type, fuel-return rule, insurance and compensation options, existing vehicle marks, emergency contact method, navigation language, ETC use and who is registered to drive. Adjust the seat, mirrors and navigation before entering traffic.
Driving safely in Iya and Kagawa
- Drive on the left side of the road.
- Stop fully where required and obey posted speed limits.
- Do not use a handheld phone while driving.
- Use a parking area before changing navigation or translating a message.
- Take breaks before the driver becomes tired.
- Never leave a person or animal inside a parked car in summer.
- Cancel or shorten mountain travel in dangerous weather.
Navigation can suggest a very narrow local road because it appears shorter. If a road looks unsuitable, do not continue simply because the screen says to proceed. Stop in a safe place and choose a main road.
Fuel and return steps
- Check the required fuel type at pickup.
- Refuel before entering a long mountain section if the remaining fuel is uncertain.
- For self-service fuel, stop the engine and follow the instructions on the pump.
- Do not guess that a kei car uses diesel; “kei” means a vehicle class, not light oil.
- Before return, refuel with the specified fuel and keep the receipt.
- Check luggage, phone cables, toll cards and the whole cabin before handing back the key.
ENEOS Mikamo Service Station is on the same site as the rental office and provides 24-hour self-service fueling. This does not mean that rental-car pickup and return staff are available 24 hours. Follow the time confirmed in your booking.
Frequently asked questions
Can an international visitor rent a car here?
Yes, if the rental conditions are met and every driver presents original documents that are valid for driving in Japan. Contact the office before booking because requirements vary by issuing country or region.
Can I use a digital International Driving Permit?
No. Japan requires the original paper-format permit prescribed by the 1949 Geneva Convention when that permit route applies.
Can I visit Iya Valley and Kagawa in one day?
It may be physically possible for limited destinations, but it creates a long driving day with little time for sightseeing. Separate mountain travel and Kagawa travel when possible.
Is there a student discount?
This guide does not advertise a student discount. Ask for the current total price for your dates, vehicle class, options and compensation plan.
Is English support guaranteed at every moment?
Use the English guide and send questions before arrival. Staff availability and communication methods may vary, so confirm how the pickup explanation will be provided.
