In 1960, Betsuyaku and Suzuki became involved in the
Anpo protests against the
US–Japan Security Treaty. The pair began producing a political theatre of protest, which eventually evolved into the
Waseda Little Theatre Company. This led Betsuyaku to neglect both his studies and his finances, causing him to drop out of Waseda in 1961 due to non-payment of tuition. Around this time, Betsuyaku took a leave of absence from the theatre to become involved in protests against the establishment of a military base on the island of Niijima. When he returned from his hiatus later that year, Betsuyaku wrote his first play,
A and B and a Certain Woman. The play was about a man, man B, who felt inferior to man A. Man B is continuously derided by man A until man B finally kills man A. The play was inspired in part by the 1957 film
An Eye for an Eye, which had a similar plot with an irresolvable conflict. Another early influence was
Samuel Beckett, whose works came to be known in Japan around the time that young playwrights in Japan were seeking to break away from
realist plays, and especially
socialist realism, which sought to further the cause of socialist revolution. Realist plays featured an impenetrable
fourth wall that was only visible to the actors, and typically made use of extensive props and detailed backdrops to make the play more realistic. However, Betsuyaku's work was like Beckett's work in the sense that it had no walls and it had very few props or background objects. For example, some of his plays had only a telephone pole, like the lone tree in Beckett's
Waiting for Godot. Betsuyaku called this "Beckett space". Realist plays feature complex characters with names to make the play more realistic. However, Betsuyaku's and Beckett's plays had simple characters with no names. This style of play was unique and open to interpretation. For example, the characters were identified as
man A and
man B instead of
Paul or
John. == Style of work ==
