This is Japan’s main program to improve energy efficiency of energy- consuming products. The program is regulated by Energy Conservation Act and sets its standard values, which should be complied to by product manufactures.

Concept of TR The target manufacturer is obliged to surpass a weighted average value for all their products per category for each predetermined target year. This is also applied to overseas manufacturers who export their products to Japan (“Importers”). The concept of using weighted average value is that this gives a manufacturer the option of producing both very efficient products and less efficient products for a variety of corporate reasons. This means that it leads the product market in the right direction while retaining product diversification yet still boosting energy efficiency of all the products as a whole. This is unique in this program where, in contrast to overseas requirements, Japanese standards do not preclude equipment that fails to meet the standards from the market.

Target Products of TR The program experienced several revisions in 2005, 2009, and 2013 now the target products are as follows : passenger vehicle, freight vehicle, air conditioner, electric refrigerator, electric freezer, electric rice cooker, microwave oven, lighting equipment, electric toilet seat, TV set, video cassette recorder, DVD recorder, computer, magnetic disk unit, copying machine, space heater, gas cooking appliance, gas water heater, oil water heater, vending machine, transformer, routers, switching unit, AC motors, LED lamp, sash(window), multi-paned glazing, multi-function device, printer, electric water heater (heat pump) and insulation materials.

Discussed matters in 2015 were:

  • Amendment of Energy Conservation Standard for electric refregilators and freezers.
  • Establishment of Energy Conservation Standard for showcases.
  • Introduction of WLTP for automobiles.
