To comprehensively investigate how regional household contribute to national carbon emission, this paper evaluates both the direct and indirect Japanese household carbon‐based emissions by using an environmentally extended input‐output table as well as the regional household consumption inventory. The results indicate that the household sector is the key driving force behind Japan's emissions, and it accounts for approximately 80% of the country's total emissions when indirect emissions are included. Moreover, significant regional differences exist in terms of the carbon footprint, which is in part caused by household and fuel‐type differences found across the country. Finally, this paper suggests that the impact of regional household and fuel‐type differences on Japan's overall carbon footprint should be a primary focus when practitioners design customized strategies to decarbonize Japan at the subnational scale. Plain Language Summary: As the major emitters of Greenhouse Gases, households release emissions both directly through combusting fossil fuels, and indirectly through by consuming goods or service. Carbon footprint represents how a household can impact the environment in both ways. Here, household lifestyles have major ramifications on the environment, and lifestyle choices may impact on the carbon footprint gap among different population groups. Our results show that households are responsible for approximately 80% of the country's total emissions. An increment of 4.19 t‐CO2 has been found at per capita level from direct to total accounting. Moreover, significant regional differences exist in terms of the carbon footprint by fuel‐type differences. We suggest that the impact of regional household and fuel‐type differences on Japan's carbon overall footprint should be a primary focus when practitioners design customized strategies to decarbonize Japan at the sub‐national scale. Key Points: This paper evaluates both the direct and indirect Japanese household carbon‐based emissions by fuel typesIndirect emission accounts for approximately 80% of the changes in terms of the country's total emissionsSignificant regional differences exist on household carbon footprint, which caused by fuel‐type consumption differences across the country [ABSTRACT FROM AUTHOR]
