(Addendum )
Partial amendments of the “Safety Regulations for Road Transport Vehicle”,
the “Public Notice that prescribes Details of Safety Regulations
forRoad Transport Vehicle”, and others
December 2014
Road Transport Bureau, MLIT
1.Background totheAmendments
Environmental regulation s ofmotor vehicles and motor -driven cycles are specified in “Safety
Regulation for Road Transport Vehicle ”(Ordinance of Ministry of Transport ,No.67 of 1951)
(hereinafter referred to as “Safety Regulation s”), based on article 41 and 44 of “Road
Transport Vehicle Act ”(Law,No.185,1951). I n order to improve aerial environment, MLIT has
adopt edexhaust gas regulations and been gradually strengthening them based on conditions
of air pollution, technological development and trends of other countries.
Central Environment Council submitted recommendations on “Future Policy forVehicle
Emission Reduction” asthe 10th report inJuly 2010 and asthe 11th report inAugust 2012 .
There are summaries below c oncerning the enhancement of emission gas regulation for
ordinary -sized motor vehicle and compact -sized motor vehicle which are fueled by diesel oil,
exceeding gross vehicle weight of 3.5t (excluding passenger vehicle for less than 10
passengers; hereinafter referred to as “diesel heavy -duty vehicle(s)”) andmotorcycles with or
without sidecars and motor -driven cycles (hereinafter referred to as “two-wheeled
vehicle (s)”).
Diesel h eavy -duty vehicles : based on the 10threport
1.Improve regula tionvalue forNitrogen Oxide （NOx）
2.Change of testing cycles
（current mode of JE05 toWHDC（Worldwide harmonized Heavy Duty Certification ））
3.Introduc eemission gas testing cycle and regulat ionvalue during off-cycle
4.Obligate mounting of a dvanced On -board Diagnostic system
Two-wheeled vehicle s: based on the 1 1threport
1.Improve regulat ion value
2.Introduce measures for reducing fuel evaporative emission gas
3.Obligate mounting of On-board Diagnos tic systemIn accordance with Central Environment Council, to strengthen emission gas regulation for
diesel heavy -duty vehicle(s) and two -wheeled vehicle(s) ,MLIT will implement partial
revisions of Safety Standards and the Announcement that Prescribes Details of Safety
Regulations for Road Transport Vehicle (Public Notice of MLIT No. 619 on 2002) (hereinafter
referred to as “Announcement that Prescribes Details ”)”
2．Outline oftheAmendment
(1)Diesel h eavy -duty vehicle(s)
(Announcement that Prescribes Details , Article No.41, No. 119, and No. 197
【Scope】
Diesel -powered o rdinary -sized motor vehicle and compact -sized motor vehicle, exceeding
gross vehicle weight of 3.5t (excluding passenger vehicle for less than 10 passengers)
【Outline of theAmendment 】
①Regulat ion value o fNOx will be improved from current average of 0.7g/kWh
to0.4g/kWh（upper limit from 0.9g/kWh to0.7g/kWh）regulat ionvalue are
asshow in the table below .

※１WHDC isthegeneric name of measuring methods by WHTC and WHSC.
Emission amount by WHTC is the numerical value obtained by adding the value
obtained by weight 0.14 to the emission amount at cold start (in the condition of cold
start) and the value obtaine d by weight 0.86 to the emission amount at hot start (inthe condition of hot start).
Each emission amount of WHTC and WHSC shall not exceed regulat ionvalue.
※２The regulated amount values in the table above indicate average (maximum) value.
②Emission te stcycle will be changed (from c urrently conducted testing cycle
JE05 mode). to WHDC ,Global Technical Regulations (GTR) that was
established by UN .
③For the purpose of maintaining the performance to reduce emission under the
conditions other than those prescribed in the t est cycle (off -cycle ),new measuring
method and regulation value shall be adopted ,based on OCE (Off Cycle
Emissions) ,established as GTR by UN,
④Advanced on-board diagnostics system （hereinafter called “Advanced OBD ”）
mounting obligation and requirements of shall be set,in place of c urrent
on-board diagnostics system ,from J-OBD -I.
⑤For vehicles which the emission amount from crankcase and exhaust pipe
ofthe vehicle is mounted turbo chargers , meets regulation value described
in①,Requirement of mounting crankcase emissions redactor may be
mitigated .
⑥Test of opacity measurement atapprov al and other conditions will be
eliminated .
(2) Two -wheeled vehicles （Safety Regulations No.31, No.61 -2 and Announcement that
