The Japanese Governor's mansion, costing approximately 5 million yen annually, reportedly only recorded nine uses throughout the year. Despite the significant investment required for its maintenance, the nominal utilization has raised concerns about efficient use of public funds. The public, policymakers and experts alike are revisiting the discussion on whether such an expense is warranted for limited use.

In Japan, the efficient use of public funds is of paramount importance and often scrutinized by the public. The governor's mansion, seen as a symbol of prestige and power, is challenging this cultural value due to its underutilization and significant cost. This has led to public and political debate regarding the necessity of maintaining such a costly official residence.

In the US or EU, budget utilization, especially for political purposes, is regularly analyzed and sometimes highly criticized. For example, controversies have arisen over the costs of maintaining official residences, such as the White House in the US or official government residences in European countries.
