In Japan, road signs (道路標識, dōro-hyōshiki) are standardized by the "Order on Road Sign, Road Line, and Road Surface Marking (道路標識、区画線及び道路標示に関する命令)" established on 1968 whose origins are Tokyo Metropolitan Police Department's "Order on Standardization of Road Sign" on 1934 and Home Ministry of Japan's "Order on Road Signs" on 1942[1]. The previous designs have been used since 1986 after several amendments of order[2].

They are divided into "Principal Sign" (本標識, hon-hyōshiki) and "Supplemental Sign" (補助標識, hojo-hyōshiki).

Principal signs[edit]

Principal Signs (本標識, hon-hyōshiki) are categorized into 4 types; guide, warning, regulatory and instruction signs.

Guide signs[edit]

Guide signs (案内標識, an'nai-hyōshiki) indicates directions or distances of the road. Guide signs have dark green backgrounds and white text for expressways. In urban areas and on national highways, direction signs have dark blue backgrounds. The signs are normally written in Japanese and English. Since 2014 Vialog is used as the typeface for English words and Place name Transcriptions.

Warning signs[edit]

Warning signs (警戒標識, keikai-hyōshiki) warn drivers of dangers or situations that they must pay attention to. Their design, black pattern and border on yellow diamond (usually with 45 cm per a side), is based on MUTCD[4].

Regulatory signs[edit]

Regulatory signs (規制標識, kisei-hyōshiki) show the regulations of each roads in order to keep road condition and prevent dangers of traffic.

The stop sign is a red, downward-pointing triangle, with the text 止まれ (tomare) in white. Prohibition signs are round with white backgrounds, red borders, and blue pictograms. Mandatory instruction signs are round with blue backgrounds and white pictograms.

Instruction Signs[edit]

Instruction signs (指示標識, shiji-hyōshiki) show points and devices on the road that drivers should pay attention.

Supplemental signs[edit]

Supplemental signs (補助標識, hojo-hyōshiki) are usually put just below the principal signs, and shows their valid range like time, day and category of vehicle[7]. They are equivalent to the "plaque" of the American MUTCD. The width of the plates is usually 60 cm, and the sentences should be less than 7 characters per a line or 3 lines[8]. When the sentences can not be shortened less than the limitation, they should apply changeable signs[8].

Other signs[edit]

"Stop" sign changes[edit]

The octagonal "stop" sign design recommended by the Vienna Convention on Road Signs and Signals

In 2016, it was announced that the Japanese National Police Agency was considering changing the design of the "Stop" sign used on Japanese roads since 1963 from the inverted red triangle sign to an octagonal design more closely conforming to the recommendations of the 1968 Vienna Convention on Road Signs and Signals.[9] The inverted red triangle sign was introduced in 1963 ahead of the 1964 Tokyo Olympic Games, and replaced the earlier red octagonal sign used from 1960, which in turn had replaced the yellow octagonal sign used from 1950.[9] It was later decided to make the stop sign bilingual in both Japanese and English, but to maintain the inverted triangular shape[10].
