After this date, they received medium plates, now in black and yellow to distinguish them from regular cars. The illustration shows what a plate might look like. The top line contains the name of the issuing office (
Tama, shown, is in Tokyo) and a vehicle class code. The bottom line contains a
hiragana character and a four-digit serial number divided into two groups of two digits separated by a hyphen. Any leading zeroes are replaced by centered dots. White plates can have the following hiragana (
bold indicates rental vehicle characters): さすせそたちつてとなにぬねのはひふほまみむめもやゆよらりるろ
れわ Green plates can have the following hiragana: あいうえかきくけこを Yellow plates can have the following hiragana: あいうえかきくけこさすせそたちつてとなにぬねのはひふほまみむめもやゆよらりるれろわを Black plates can have the following hiragana (
bold indicates rental vehicle characters): り
れ Some characters, including ones with a
dakuten or a handakuten, be used on any plates, including the yellow and black ones: ばだがぱざびぢぎぴじぶづぐぷずべでげペぜぼどごぽぞ In addition, these hiragana cannot be used on any license plates due to various reasons explained below. おしへゑゐん The hiragana お is not used because it is too similar to the hiragana あ especially if there is a car crash. The hiragana し is often thought to represent the kanji 死, which means death so it is not used. The hiragana へ from a distance can look like an arrow → so they do not include it. The hiragana ゑ and ゐ are very old and are not used commonly so to avoid confusion they are not used. The hiragana ん, which is pronounced n, is hard to get across quickly over the phone so it is not used. announced in early 2009 that prefectures may now choose their own color scheme and possibly pattern. This is already being done with the motorcycle plates for
Matsuyama, Ehime. A
license plate in
Japan thus follows this format: KK?*H##-## (e.g., 足立500き21-41), where KK is the name of the issuing office in
kanji, H is a hiragana, ? is a 5 for vehicles less than 2000 cc and a 3 for vehicles greater than 2000 cc (other numbers are less common—1 for large trucks, 2 for buses, etc.), * is a number from 0 to 99 (pre-1971 license plates will omit this), and # is a number from 0* to 9 (*leading zeroes are replaced by centered dots).
Special use plates only attached when the Emperor himself or the Empress is in the car Vehicles owned by personnel with the United States military in Japan under the
Status of Forces Agreement (SOFA) have a "Y" on white plates and an "A" or "B" on yellow plates, where the hiragana character is normally displayed. Earlier versions of the SOFA license plate displayed the letters "K", "M", "G", "H" and "E". These letters indicated the car was imported into Japan under SOFA and was left-hand drive. Today, cars with an "E" indicate that Japanese sales tax has not been paid and the vehicle will not remain in Japan when the military member departs. Since the 1980s, military commands have discouraged servicemembers assigned to Japan from shipping their vehicles from the U.S. into the country, so this is rarely seen. Military members who retire in Japan use the hiragana "よ". Many opt to purchase second-hand domestic vehicles through used car dealers off-base, and from other servicemembers departing Japan at on-base "lemon lots". The official imperial cars have a special number plate with the kanji 皇 and a one-digit number below.
Out of country plates Because the
Japanese writing system, particularly the
kana, is unique to Japan, standard-issue Japanese license plates are considered unacceptable for international travel. If motorists wish to take their vehicles abroad with them, the Ministry of Transport will issue them with plates with the hiragana and kanji scripts replaced by Roman letters. The hiragana prefix is replaced by a
Kunrei-shiki romanization of that character. The kanji
prefecture/office code is replaced by a two- or three-letter abbreviation, the first two letters representing the prefecture, the third (if present) representing the office within the prefecture. All the numerical portions of the plate remain the same. Using the example given above, the plate (足立50Kき21-41) would then read TKA 50K
KI 21-41 (TKA for
To
kyo
Adachi). == Vehicle class code system ==
