First, I had to get a paper from my city government office that showed that I lived where I said I lived. No matter that I had just gone through the two-week process of getting an official alien registration card with the same information on it. Couldn’t use that... The official paper costs about $2.
Next I had to get my California license officially translated at a JAF office (Japan Automobile Federation) - $30. Because of my work schedule and general ignorance of where to go and what to ask for, my friend Yoh-san took care of that for me by taking a morning off from his experiments and riding the train to some faraway city where said office is conveniently located. He also picked up a book for me called Rules of the Road, a well-translated English version of Japanese driving regulations - another $10. Yoh-san also ordered a book online for me that had several practice tests in English - another $20.
I had a weekend to study the tests before Mitsuru-san took a Monday off to drive me to the licensing building - hereafter called the Menkyo Center. I had read online that the gentsuki (scooter, remember?) test was 50 questions and the first three practice tests were 50 questions, too, so that’s what I spent my weekend studying. (Actually, I had also read somewhere that the test was only ten questions. That’s what I was hoping for).

The books were pretty straightforward, except for a couple of things. For example, overtaking and passing are two different things. Overtaking is passing something slower without crossing into oncoming lanes.
This happens quite a lot here, with lots of bicycles and scooters as well as pedestrians on the road. Outside of the big cities, sidewalks don't always exist. I think this is a holdover from the past. The streets are actually for pedestrians. The vehicles are just allowed to use them, too.
Passing is the crossover into the other lane. There are just slightly different signs prohibiting each. Also, there are three different signs that mean 1) road closed to all vehicles, 2) road closed to vehicles, and 3) no entry. The book did not do a good job explaining the difference, or the need, for that matter. In addition, the English translation for these signs on the practice test was a bit garbled. True or false - this sign means cars cannot enter. False - it means ‘No entry’. They throw little technicalities like that at you for no other reason than trying to trick you.
Well, the weekend just flew by with me trying to figure out things like that and bright and too early Monday morning, Mitsuru-san showed up at my apartment to take me to the Menkyo Center, conveniently located in the middle of nowhere about an hour’s drive from my town. That’s not really fair, I guess. I’m sure it’s very convenient for the people living in the town in which it’s located. That just doesn’t happen to be my town.
So we drive the hour and arrive in plenty of time to start the process of converting a foreign license, which takes place only between the hours of 9:30 and 11. We found the correct office and sat down to wait our turn. Next - the Menkyo Center.
