Maraknya protes sosial pada zaman Taisho dilatarbelakangi oleh kesenjangan sosial yang terjadi di Jepang. Protes ini dipelopori salah satunya oleh kelompok intelektual yang memiliki paham sosialisme. Paham sosialisme kemudian berkembang menjadi aksi massa yang dipengaruhi oleh kelompok anarko-sindikalisme yang menginginkan penghapusan kesenjangan sosial secara langsung. Akibat pengaruh Revolusi Bolshevik di Rusia, kelompok anarkis kemudian menjadi cikal bakal Partai Komunis Jepang. Tindakan komunis yang bergerak secara anarki ini segera ditindas oleh pemerintah sehingga pada tahun 1924 Partai Komunis Jepang dibubarkan. Berangkat dari kejadian tersebut, penelitian ini difokuskan untuk melihat upaya apa yang dilakukan oleh pemerintah dalam bentuk kebijakan sehingga dapat meredam pergerakan kelompok komunis Jepang yang disinyalir dapat membawa lsquo;pemikiran berbahaya ke Jepang rsquo.
