Sho-Gekijo mainly focused on making theatre accessible to the proletariat as opposed to a then-popular philosophical art which arguably required a degree of education to appreciate.
However, since the play was registered as created by Mitani Koki as opposed to "The Sunshine Boys", the producers took over and held auditions for the cast.
From that point on, Mitani Kōki as the writer for the Tokyo Sunshine Boys as well as the actors themselves, got flooded with offers to work on other TV dramas, plays and movies.
Their stories specialised in the creation of a work - be it a play, a radio drama, or a house - of people cooperating, a multitude of opinions being brought into consideration, and the pros and cons thereof.
The 1997 film Welcome Back, Mr. McDonald, was based on the play "The Radio Time" by Mitani Kōki and performed by the Tokyo Sunshine Boys.
