THE BASICS
The Japan Automobile Federation (JAF) provides its Rules of the Road in six languages.
You can send 1000 yen plus return postage to your local JAF office and get a copy mailed to you
(office locations and more information available at
http://www.jaf.or.jp/e/index_e.htm)
The Rules of the Road book itself is not very long. It has a variety of illustrations and is
translated well. However, the great majority of it is common sense and often such irrelevant
common sense (such as 'do not disturb people by revving your engine'), one is discouraged from
taking it seriously. However, there are some useful items within not least of which is a
full color guide to all road signs, center lines and other street markings, as well as
explanations on what a parking ticket looks like and what to do if involved in an accident.
If one has not driven in a long time or is a relatively new driver, it is definitely worth
looking into.
However, although Japanese driving rules are fairly standard, there are a couple things to watch for:
Americans and Canadians, note that Absolutely No Turns can be made on a red light in Japan.
British, Australians and New Zealanders, note that the Give Way to Cars on Your
Right rule is the opposite. For example, if you are turning left onto a street and a car
across from you is turning right onto the same street, you have the right of way.
In other words, the car making the smaller turn goes before the car making the larger turn,
even if it is crossing from your right.
Other things to note:
- Seat belts must be worn in the front seat by law.
- Pedestrians always have the right of way. (Despite this, Japanese do not jaywalk often.)
- Give way to emergency vehicles (even if Japanese drivers tend not to.)
- A recent law makes driving while talking on a mobile phone an offense.
- Stop at all railroad crossings, regardless if there are warning lights or barriers.
- Motorcycle riders must wear helmets
- Children under the age of 6 must be in a child-safety seat
- Beginning drivers must attach a Learner's sticker and drivers over 75 must attach a Senior Driver's sticker
Lines
You will see white lines, yellow lines, dashed, solid, and a mixture. The lines do not indicate
traffic flow so assume every road goes in two directions (no matter how narrow it is)
unless you are on the expressway. Basically, the rule is that, if the line is dashed,
you may pass, overtaking the car in front of you. If the line is a solid white, you may pass but
exercise caution. Never cross a solid yellow line at all unless there is an additional white
line on your side. This is especially true if it is a thick yellow line. Also, as a general rule,
there is no passing allowed in a tunnel.
Traffic Signs
Traffic signs are not written in romaji at all, though many are self-explanatory.
See Rules of the Road or your JET Diary for a complete list. Some ones to watch
for are:
 STOP tomare
|
 SLOW jokou
|

ONE WAY
|
 NO PASSING

If you see a lit sign full of kanji, it is almost always warning of a construction zone ahead.
Despite the intimidating number of kanji, it is almost never something to worry about.
Construction Zones
Construction is common, especially construction that reverts traffic to one lane. These zones
are either monitored by live workers or by small lights. If a worker waves a red flag at you,
you must stop. If a worker waves a white flag, you may proceed. If a worker is waving a sign
with two giant kanji, it usually means 'slow' indicating construction ahead. There may
be a single light during off-peak times. Simply: stop if it is red and proceed if it is blue or
green. (Often, a timer shows how long you have
to wait before you can proceed - no more than 2 minutes.)
Beware of wildlife on country roads, especially in spring and autumn.
Navigation
Getting from one place to another in Japan by car is relatively easy. Almost all signs, even
in rural areas, have romaji under the kanji as well as clear arrows, so the language
barrier is rarely a problem when navigating. Local roads are narrow and twisty, but well-marked.
City roads are more of a challenge since there are more lanes, more cars, sudden forks, and
less time to decipher signs; in particular, avoid driving in the Tokyo-Yokohama area or the
Osaka-Kyoto area unless you have to. Blue signs are the main navigation signs; they will
show the main routes. Green signs indicate toll expressways. Almost all local routes
have numbers.
A great road atlas in English is available from Shobunsha called Road Atlas Japan.
The color maps are topographic. All routes, towns, landmarks, and major tourist attractions
are written in English with kanji included for city names. It is available from a
variety of bookshops and online including from Amazon Japan.
The price is approximately 3000 yen. (ISBN 4-398-20104-1)
Gas / Petrol Stations
Gasoline Stands, as they are called in Japan, are fairly similar to their counterparts
elsewhere in the world. The cost is rarely advertised, but hovers just over 100 yen a liter.
They are usually full serve, but keep an eye out for the katakana "self" (セルフ) just to be sure.
Self-serve gasoline stands often have a fancy Japanese-only push-button screen and want cash
ahead of time. If you get stuck, a clerk will probably help.
Good words to know: mantan 満タン (the equivalent of "fill 'er up."
Otherwise, you can ask for a specific amount of litres/yen), genkin 現金 (pay by cash),
regyura レギュラ (regular unleaded gasoline), and haizara 灰皿 (ashtray; they may offer
to empty it)
Being that Japan is still very much a cash society, there is no credit card pay at the pump.
Also, snacks and the like are rarely available at a gasoline stand; you have to go to a convenience
store. In addition, if you are in the countryside, most gasoline stands will close quite early
(7:30 or 8pm) and will be closed on Sundays and holidays, so plan accordingly.
Pedestrians and Cyclists
Pedestrians are supposed to walk on the right side (unless there are sidewalks) while cyclists
are supposed to ride along the left side of traffic.
Breakdowns and Accidents
If you are involved in an accident, call 110 to report it to the police. If there are injuries,
call an ambulance at 119.
If your car breaks down, there are a number of road service providers, however,
the standard is the Japanese Automobile Federation (JAF). If you are not a member
(or are not carrying your card) JAF will assist you, but the service fees start at 5,000 yen and
go up from there, depending on where you are and what you need. Flat tires often cannot be
fixed on the spot.
The number to call (it should work from mobile phones, pay phones, PHS, etc.) is:
# 8 1 3 9 (Don't forget to press the pound sign first)
(Japanese mnemonic: ha-i-san-kyu or "hai, thank you")
Be prepared to tell them your location, model of your car, and the nature of the breakdown
(the best you can.) If you call from an expressway emergency phone or the like,
they can pinpoint your location easier.
