Auntie BEEB Radio 4 aired the radio drama over three days called "A Tok yo Murder" on Tuesday.
In the we've already had maid cafes and dutch wives popping up in the dialogue and overall, the play is more interesting for the way it chooses to depict Japan and the foreigner experience.

I would say its rather "Orientalist", especial in the drama's ending music* and choice of the overly-cute Japanese announcer. Listen to the last 10 seconds of the dialogue of Part 1 and 30 seconds of the closing credits with "Asian"* music.

*Asian-esque gamelan style music in not Japanese any more than Turkish belly dancing music sounds like Irish folk songs.
