Alleged Census Inflation in Toyama Raises Concerns Over Data Integrity
Japan's 2025 census results sparked suspicion that Toyama city inflated its population to stay above the 400,000 threshold, a claim the mayor has denied.
When Japan published the final numbers from its 2025 census, Toyama city came under scrutiny for allegedly inflating its resident count to remain above the 400,000 mark required for certain administrative benefits. City staff are suspected of modifying census forms, resulting in a preliminary figure that was about 3,000 higher than the actual population, which has fallen below the threshold. The mayor has publicly denied any wrongdoing.
The issue echoes historical concerns: Prime Minister Takahashi Hara initiated Japan's first national census in 1920 after studying French methods, and Shigeru Yoshida later warned that wartime governments often reported only convenient figures. Such manipulation, if widespread, could undermine policy decisions that rely on accurate demographic data. The column highlights the broader risk of eroding public trust in official statistics.
