The upcoming "double election" in Osaka, involving both the mayoral and gubernatorial elections, is projected to cost around 2.8 billion yen. The comprehensive cost, not just the candidates' expenses, encompasses various aspects such as administrative efforts and security measures. The elections, known as "W elections" in Japan, originate from the unique governmental structure of the Osaka metropolis and prefecture, drawing significant attention from all over the country.

In Japan, where fiscal responsibility is a recurring political issue, the high cost of the "double election" has sparked intense public debate. It also intersects with broader discussions about the Osaka metropolis plan, a controversial proposal advocating for the reorganization of the government structure in Osaka. Overall, it highlights existing concerns about bureaucracy and the efficient use of public funds.

The US or EU also grapples with the cost of conducting elections, with the 2020 US presidential election being one of the most expensive on record. However, they rarely face a scenario comparable to Osaka's double election due to their different administrative structures. In the EU, elections happen simultaneously for all member countries, whereas, in the US, state and federal elections sometimes overlap, but not usually requiring separate ballots or admin effort.
