Summary
Japan’s inheritance tax landscape has drastically changed over the past decade, impacting not only wealthy families but also ordinary households. Key changes include a significant reduction in tax exemptions in 2015, a sharp rise in urban land values, and fewer heirs due to declining birth rates. These factors have collectively lowered the tax-free inheritance threshold and increased tax burdens. For example, a property valued at ¥700M in 2015 now incurs ¥395M in taxes due to land appreciation. Additionally, spousal exemptions only apply during the first inheritance, leaving families unprepared for subsequent tax obligations. Rising land values, particularly in central Tokyo, have doubled in some areas, further exacerbating the issue. This trend highlights the growing financial strain on families, even those with modest assets, as inheritance taxes continue to climb.
