The Japanese government adopted the "Basic Program for Housing" on 19 September 2006, planning to improve housing standards over the next 10 years. The plan was presented by the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) on 28 June 2006 based on the current Basic Act for Housing, which has been in effect since 8 June 2006.

The Ministry has clear targets for housing by 2015. Building efficiency in two of the four target areas:

3) 40 percent of housing should adopt energy saving measures, for example double-paned windows (18% as of 2003);

4) to increase the life span of housing to about 40 years (about 30 years as of 2003).

By regularly analyzing and evaluating the effectiveness of the project using target assessment indicators, the Ministry intends to reappraise and modify the plan in five years based on the effectiveness of these measures and changes in social conditions.


The plan was revised in March 2011 and the latest plan includes the following energy efficiency measures for housing for the period from 2011 to 2020:

The Target
The new basic plan specifies the clear energy conservation target for new houses as follows: The rate of achieving the standard of the energy conservation act: For newly-built houses, 100% achievement rate in 2020 compared to 42% in 2010.   The concept to include energy conservation performance in the basic housing plan is that it identifies the low carbon lifestyle as a part of the national housing and lifestyle policy in Japan.  

Measures to Realize the Target
The basic plan shows that concrete measures to realize the energy conservation target for houses as application of energy conservation measures such as installing double glazing window sashes for the half of the houses of the whole housing stock. There are several methods presented in the plan to achieve the goal and one of them is a promotion of energy conservation labeling for houses which realizes the visualization of the performance. National PR actions are presented as one of the methods, too.

In addition, in the Basic Energy Plan published in 2014, the policy direction regarding the housing sector was stipulated that the government will facilitate energy efficiency in the sector through possible strengthening of energy efficiency standards, further dissemination of ZEH (Zero Energy House), and promotion of smart lifestyle, etc.
