Ministry of Economy, Trade and Industry  
 
1. Background  
Under the Act on the Rational Use of Energy (Law No. 49 of 1979; hereinafter referred to as 
the “Energy Efficiency Law ”), the Minister of Economy, Trade and Industry  shall es tablish and 
publicize standards  for manufacturers/importers  (hereinafter referred to as the 
“manufacturers, etc.”) , with regard to the improvement of the energy efficiency performance 
for the respective equipment  which is specified in Cabinet Order under the Energy Efficiency 
Law including  televisions .  
In addition, the energy efficiency standards shall be established taking into consideration 
the highest level of energy consumption performance of the respective spec ified equipment 
and other related factors (as it is called the "Top Runner Program").  
The Minister propose s new energy efficiency standards for televisions  to promote 
rationalization of energy use pertaining to t elevisions  in Japan in order to cope with the 
recent increase of  energy consumption in the household sector, climate change, and so 
forth.  
 
2. Outline of amendment  
(A) Scope  
Televisions ：liquid crystal televisions （LCD TV）, organic electroluminescence televisions
（OLED TV ）  
 
(B) Energy consumption efficiency and measurement method  
The energy consumption efficiency shall be the "annual power consumption" and shall be 
the numerical value (kWh / year) calculated by the following formula s. 
 
【TVs with built- in recording device s】 
E＝｛（ Po－PA／4）×（to－torec）＋（Porec －P A／4）×t orec 
＋Prec× trec＋Pepg ×tepg＋P S×（24 ×  365－t o－trec－tepg ）｝／1000  
 
In this equation, E, Po, PA, Porec , Prec, Pepg , PS, to, torec, trec, and tepg each represent s the 
following numerical values . 
 E: Annual power consumption (kWh / year)  
Po: Power consumption during  operation (W)  
PA: Reduced power consumption by power saving function, etc. (W)  
Porec: Power consumption during operation and recording (W)  
Prec: Power consumption during recording (W)  
Pepg: Power consumption at the time of EPG data acquisition (W)  
PS: Standby power consumption (W)  
to: Annual standard operating time (h / year) 1861.5 (5.1 hours × 365 days)  
torec: Annual standard operation and recording time (h / year) 146 (0.4 hours × 365 days)  
trec: Annual standard recording time (h / year) 146 (0.4 hours × 365 days)  
tepg: Annual standard EPG acquisition time (h / year) (depending on the device)  
 
【TVs other than TVs with built -in recording device s】 
 
E = {(Po -PA / 4) x to + Pepg x tepg + P S x (24 x 365- to-tepg)} / 1000  
In this equation, E, Po, P A, Pepg, P S, to, and tepg each represent s the following numerical 
values.  
 
E: Annual power consumption (kWh / year)  
Po: Power consumption during operation (W)  
PA: Reduced power consumption (W) by power saving function, etc.  
Pepg: Power consumption at the time of EPG data acquisition (W)  
PS: Standby power consumption (W)  
to: Annual standard operating time (h / year) 1861.5 (5.1 hours x 365 days)  
tepg: Annual standard EPG acquisition time (h / year) (depending on the device ) 
 
(C) Target fiscal year  
FY2026.  
 
(D) Category and targeted standard value  
The categor ies and targeted standard value s are as follows.  
 
Table 1. Targeted standard value s for Televisions  
Category  
name  Category  Targeted standard value (kWh / year)  a LCD TVs less than 2K  0.00407A+ 30.08  
b LCD TVs 2K or more 
and less than 4K  0.00605A+56.13  
c LCD TVs 4K or more  0.00727A+62.99  
d OLED TVs  0.02136A -16.40  
※75.0 if A <4,258  
A: Screen area (square centimeter)  
 
 (E) Method to determine achievement  
Energy consumption efficiency of the equipment shipped in each fiscal year after the target 
year, which is weighted  with the number of units shipped for each category , should not 
exceed the value of the energy efficiency standard, which is weighted with the number of 
units shipped for each category. However, the following two exceptions are provided.  
 
①  Consideration of additional functions  
If the category has not reached the energy efficiency  standard , and the annual power 
consumption of each product , which was weighted  with the number of units shipped by the 
category , does not exceed the  energy efficiency standard  by subtracting the estimated annual 
power consumption of each additional function shown in the table  below , it can be considered 
that the consumption efficiency does not exceed the energy efficiency standard in the category. 
 
Name of additional function Estimated annual power con
sumption（kWh/ year） 
Built- in 2K tuner (2 or more)  2.8 
Built -in 4K tuner (2 or more)  5.5 
Built- in recording device (HDD 3.5 inch)  11.0 
Built- in recording device (HDD 2 .5 inch)  4.8 
Built -in recording device (SSD ) 3.7 
Built- in Blu -ray disc recorder or DVD recorder 
(complying  with 4K or more  ) 23.9 
Built- in Blu -ray disc recorder  or DVD recorder 
(complying with  less than 4K)  16.7 
Double speed  Video  display ( complying with  4
K or more ) 18.3 
Double speed Video display ( complying with le
ss than 4K)  17.0 
 ②  Consideration of 8K equipment  
If the TV  is classifi ed as liquid crystal 4K or higher and organic EL and does not achieve  
the energy efficiency  standard, it can be considered that its  energy consumption efficiency 
does not exceed the energy  efficiency standard if its  annual power consumption of each 
category , which is weighted with  the units shipped, excluding 8K equipment , does not exceed 
the energy efficiency  standard obtained by the weighted mean  of the number of units shipped 
in the  category . 
 
4. Proposed date of entry into force  
Around May  of 2021*  
*Target fiscal year for achieving the new standard is set to be FY2026.
