I had road trip from Miyako to Tokyo by my K-car last weekend. Somewhat I thought Tokyo is much farther from here Miyako, but it was only 600 kilo meters which is only 375 miles. I used to drive hundreds and thousands of miles by myself when I was in the US. So, when I found it's only 600 km between Miyako and Tokyo, I thought I could make the round trip. It sounds lots of driving (well, it was,) but it was actually fun. Here are some advises from my experience for whom planning to drive to Tokyo. - On the way from Miyako to Tokyo, there are many PA/SA (Parking Area/Service Area where you can park your car and take some rest, bathrooms, vending machines, etc,) gasoline stations, restaurants, and so on along the Tohoku Highway, BUT, on the way back from Tokyo to Miyako. I had a chance to fill the gas on the way back, but at the moment, I had about half tank of the gas; then I decided to fill the tank at the next gas station....
