Japan's Prime Minister Sanae Takaichi has called a snap lower house election on February 8, which analysts say is shaping ‌as one of the most unpredictable contests in years. Here are five reasons why:POPULARITY GAPSince becoming Japan's first female prime minister in October, Takaichi has won strong approval ratings. For example, in the October 2024 lower house election in Tokyo, the capital, just 36% of those aged 21 to 24 voted, versus 71% of those aged 70 to 74. Its ‍push follows a breakout performance in July's upper house election when it ‌bled support from the LDP ‌to win 14 seats. This ‌is only the third February lower house election in ‍the postwar era and the first since 1990.
