Reformist party (Japan) Source: en.wikipedia.org/wiki/Reformist_party_(Japan)

Kakushin Sētō (革新政党) means reformist party[1] or progressive party[2][3] in English. Kakushin Sētō is generally 'anti-conservative', and in Japan, it has generally referred to democratic socialist, social democratic and socially progressive parties that respect parliamentary democracy. Japan's "progressive parties" are basically opposed to constitutional amendments led by right-wing conservatives, so they are partly in solidarity with "liberal parties".

In general, while the Liberal Democratic Party has a strong conservative tendency and the Communist Party has shown a strong progressive tendency.[3] in the Japanese political spectrum. In the 21st century, not only traditional democratic socialist parties but also some progressive liberal parties began to be regarded as part of the Kakushin Sētō in the Japanese political context.[4][5]

List of Kakushin Sētō[edit]

During the Japanese Empire[edit]

  • 1926: During this period, as the proletarian movement was activated, the legitimate socialist party Labour-Farmer Party was founded.
  • 1926: At that time, moderate socialists who were compliant with the system formed the Social Democratic Party. At that time, it showed the relatively most conservative tendency among Japan's three major proletarian parties.
  • 1928: The Labour-Farmer Party was forcibly disbanded as the government launched a massive crackdown on socialist forces.
  • 1932: Moderate leftists supporting the constitutional rule of the Japanese Empire founded Shakai Taishūtō.
  • 1940: With the establishment of a one-party system led by the Shōwa statist Imperial Rule Assistance Association (IRAA), Shakai Taishūtō was absorbed into IRAA, and all other Kakushin Sētō were banned.
