The road traffic law is common(=only one) throughout the country.
I have to say that PDF in above post content is NOT enough.
If I actually took the written exam, it was such a matter of contents.
http://verfumi.web.fc2.com/international/license_test_exercise.htmThis is a Hokkaido version(including driving on snow/ice road),
but this is very helpful as a guide written in EN, especially not only about traffic law.
http://www.hkd.mlit.go.jp/topics/toukei/chousa/h20keikaku/e/e_all.pdfWell, do not know how much Japanese you can read,
but getting a "交通教本(koutsuu-kyouhon, =bible/text book of driving)" is not so hard.

Did not you get it when you got a license of Japan? (just cannot read?)
I've noticed a few differencesBasically, the yellow(orange) lines means can not over the line to lane change
(near intersections and blind curves and tunnels, mainly) and overtaking.
but only you can escape for parking cars, stopping vehicles (such as buses and trucks)
and constructions, or entering a shop on the opposite lane
and when the previous car deliberately slowed down speed for overtaking.
(move to left side with left blinker, or open window and signal "overtake" by hand)
Also, stopping at a railroad crossing is not must,
only in places where are controlled by traffic lights for cars,
this is one of exceptions, often used in exam questions, so basically have to "stop".
The reason is very simple, bc trains always need longer stopping distance,
and it is also necessary to predict that rail crossing machine is broken,
and in the countryside, without lights,alarm and rod/arm type is not so rare.
(In places where visibility is bad, train operators are required to use alarms,
however, this is not what you learn at school of driving.)
At driving school teaches,
have to check the sound of the train approaching by opening the window,
but in fact, most drivers are doing only visible, and even if you can not open the window it,
policeman/vehicles will not follow you as a violation, non or too short stop will be violation.
Also you can put/paste a "beginner sign(sticker, thin magnetic plate)" on the car.
https://en.wikipedia.org/wiki/Shoshinsha_markYou can buy it at 100Yen(108Y,w/sale tax) shops, even you can make it by myself.
Although this is not an offense to the violation when you fail,
but if another driver intentionally disturbs your driving, they will suffer severe penalties than usual.
Differences in driving in Japan have been pointed out by some YouTubers.
You can search title of movies, I also watched it by famous YouTuber who(he) came from UK.
"Thank you! hazard(brinkers flashing)" is one of famous mannar,
but this is not formal action as law of driving, however, police man(car) of traffic won't move if watched.
https://www.reddit.com/r/videos/comments/2dswe3/how_japanese_drivers_s...US and more wide country drivers are surprised about direction of parking is also famous.
http://www.penchan.com/mak/img/us2012/parking-japan-vs-us.pngThis is also not traffic law, just one of custom. (except Expway parking)

In recent years, attempts to increase this type of intersection, but it has not increased rapidly.
http://rabico.cocolog-tnc.com/gmt/2014/03/post-9be1.htmlIt has not been in Japan since long ago, but this is an experiment to prevent car accidents.
https://en.wikipedia.org/wiki/Collision_coursehttps://matome.naver.jp/odai/2136151237248064201https://carby.jp/topic/1031788If you check at the table of penalties for traffic violations,
you will understand what violation is important as well.
http://www.keishicho.metro.tokyo.jp/menkyo/torishimari/tetsuzuki/hanso...Line of 普通車(futsuu-sha) is so, including "kei(smaller size body and engine)" car.
In Japan, serious accidents such as "reverse run" increase
by aging progresses =elder drivers, which is one of new problem of traffic.
Also, many young people are getting away fr buying cars and motorcycles,
so bicycles are increasing, but they are not interesting in convenient vehicles,
just for paying cellphone and games, mainly in urban areas, though.
Anyway, recommend you to contract a good insurance ASAP, if yet.
Only with "liability insurance(=Jibaiseki)" is no enough.
