Your Journey Begins at Shimojishima Airport (SHI)

No. Japan requires an International Driving Permit (IDP) for all foreign visitors. Your US license alone is not valid for driving in Japan. You'll need an IDP issued in the US (through AAA) along with your original license. Processing takes about 10-15 minutes at AAA offices. The IDP costs roughly $20 and is valid for 1 year.

Yes, it's a significant adjustment. Japan drives on the LEFT side of the road, meaning the steering wheel is on the right. US drivers often struggle at intersections, roundabouts, and when merging. Take extra caution at T-junctions and when turning. Consider starting on quieter roads for your first 30 minutes behind the wheel. Nearly 90% of rental incidents involving US tourists involve right/left confusion.

Miyako Island itself has minimal toll roads, but if you connect to the Okinawa Expressway on the main island via ferry, expect tolls of roughly ¥2,000-3,000 ($14-21). Rental cars typically come equipped with an ETC card for automated payment—just return it with the vehicle. Cash lanes still exist at most toll booths. Budget about ¥3,000/day for expressway tolls if exploring beyond Miyako.

The minimum driving age in Japan is 18, but most rental companies require renters to be 21-25 years old. If you're under 25, expect a "young driver surcharge" of roughly ¥1,000-2,500 per day ($7-17). Some agencies like Times Car Rental and Toyota Rent-a-Car charge ¥1,500/day for drivers aged 21-24. Always check the age policy before booking, as some luxury vehicles have higher minimum ages.

Yes. Miyakojima is in the typhoon belt with peak season from July-October. During this period, roads may close with little notice, and ferry services can be suspended for 1-3 days. If you're renting during these months, choose a rental company with free cancellation and avoid coastal roads when storm warnings are issued. The islands have excellent emergency shelter infrastructure, but road conditions can deteriorate quickly with heavy rain and wind.
