Japan has always been known for its technological innovations in different industries. The tech industry in Japan is huge and is one of the main forces when it comes to Japan’s progress. 

Recently, a lot of industries and companies in Japan have begun moving their focus to sustainable buildings and development. This includes developing technologies that can help move Japan towards zero energy emissions. 

In this article, we’re going to look at Japan’s Zero Net Energy Houses (ZEH) policy and how it can help with the climate crisis we’re currently facing. 

Japan’s Zero Net Energy Houses (ZEH)



In April 2014, the Zero Net Energy Houses (ZEH) energy policy was approved by the Japanese government. This policy was so that ZEH was to become the standard to follow for new house constructions by 2030. ZEH is designed to consume as much energy as it can via renewable energy that is produced on-site.

The Japanese are well known for combining practical and high-quality technological innovations with perplexing beauty and it is the same with their green architecture projects. Japan is one of the countries that is leading the race to a greener future for the planet. 

In the past, residential houses in Japan were only designed to last around 35 years before they had to be rebuilt or torn down. However, today, Japan is moving forward with sustainable green homes that can last pretty much forever. Sustainable home improvements include proper heat insulation, LED lights, efficient air conditioning, and more.  

One of the forerunners in zero carbon emissions in Japan is MUJI house. They took a huge step by releasing the Vertical House located in Tokyo, Japan. The building accommodates all the needs a resident might need within a small plot of land. 

MUJI House considered the tight urban context of Tokyo when they designed the Vertical House. The building is 3-story tall and lacks any interior walls or doors. The Vertical House also features huge north-facing windows so that ample sunlight can illuminate the interior during day time.

The demand for zero-energy standards will increase even more in Japan as the trend grows. With this, comes even more development and technological advancements. Even though the pandemic has delayed some of the progress, Japan is still going strong as one of the leading countries on the road to Zero-Carbon emissions.
