In Daijoyuu Satsujin Jiken, the 2018 TV Asahi Japanese adaptation of The Mirror Crack'd from Side to Side, Akada Shimeko (朱田〆子 - Shimeko Akada in Western format) is the secretary of Kaido Akira (Jason Rudd). She is a fairly close parallel of Ella Zielinsky from the original novel. Like in the original, she doesn't like her employer's wife Iridori Madoka (Marina Gregg). She is secretly in love with Kando. She tells police that she has worked for Kaido for 16 years whereas Madoka has only been married to him for eight years.
Like Ella, She suffers from some allergy which causes frequent sneezing and uses an inhaler. After the poisoning of Kannokoji Rin (Heather Badcock), Shimeko sends a series of record phone threats randomly to potential suspects. These have been digitally altered to make it doing like a male voice but Danbara Hiraomi (Ardwyck Fenn), one of the recipients, is able to easily identify Shimeko because Sneezing can be heard. Like Ella, Shimeko is killed by poison in her inhaler, in this case arsenic, although it is not clear how poison is easily inserted into the modern day disposable inhaler which she used.
Akada Shimeko is portrayed by Nishio Mari (西尾まり).
