Immediately after the end of the war, today, on August 20, in Karafuto, nine Maoka Post Office telephone operators killed themselves after continuing to report the situation of the Soviet invasion by telephone. At that time, the telephone played an important role as a means of quickly transmitting information, and the telephone operator was a star occupation for women. The duty was heavy, and she was always tense, but during the lunch break, everyone returned to a normal girl and enjoyed chatting. However, right after the end of the war, the Soviet army suddenly invaded Karafuta and the pleasant time was suddenly cut off. Two days later, Soviet troops landed in Maoka. Nine exchangers said, “This is the last report for you . Goodbye, goodbye.”, drunk potassium cyanide and killed themselves.

終戦直後の今日8月20日、樺太で、真岡郵便局の電話交換手9人が、ソビエト軍の侵攻の状況を電話で伝え続けた後、自ら命を絶ちました。電話は当時、情報をいち早く伝える手段として重要な役割を果たしていて、電話交換手は女性たちにとって、花形の職業でした。その責務は重く、常に緊張を強いられましたが、昼休みだけはみんな普通の女の子に戻り、おしゃべりを楽しんだそうです。しかし終戦直後、ソビエト軍が樺太に侵攻し、楽しい時間は突然断ち切られました。その2日後、ソビエト軍が真岡に上陸。交換手達9人は「みなさんこれが最後です。さようなら、さようなら」と告げ、青酸カリを飲んで自ら命を絶ちました。
