Vehicle Classification

While vehicles are categorised from 0-9, privately registered vehicles utilise numbers 3 and 5 only. Standard cars with a maximum capacity of ten persons will display 3xx, with small and kei cars displaying 5xx.

In addition, cars utilising only two numbers for classification can still be seen today, e.g. 3x and 5x. These vehicles were registered prior to the 14th of May, 1999, with the exception to kei cars which changed to a 3-digit classification system in January 2005.

Hiragana Characters

The hiragana symbols to the left of the number plate specifically identify the type of use for each vehicle. Privately owned vehicles of small and standard cars use the following:

さ・す・せ・そ・た・ち・つ・て・と・な・に・ぬ・ね・の・は・ひ・ふ・ほ・ま・み・む・め・や・ゆ・ら・り・る

While kei cars use the following:

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・や・ゆ・ら・る・を

NB: Vehicles identified with the hiragana わ are reserved for rental vehicles only, while non-Japanese character based number plates (E, H, K, M, T and Y) belong to users of the U.S. army based in Japan.

4-Digit Number

Split into two groups of two-digits with a hyphen in the middle for ease of reading. Numbers range from 1 to 99-99. Numbers not used in personalised number plates are replaced with a centered dot. With the exception to U.S. Army vehicles, numbers 42 and 49 are prohibited on the last two digits due to their connection with death.

Colour Configuration

Vehicles with a yellow number plate are reserved for kei cars with an engine capacity of 660cc and below, with small and standard vehicles possessing a white plate.

Other colours include, but not limited to, blue; reserved for diplomats from consulates and embassy staff, and green, specifically for commercial vehicles - such as taxi's.
