喺國鐵時代，1970年代後半開始用電子音化嘅電鈴（類似「biro-biro-biro-biro」嘅聲音）提示開車，但未能獲得好評。因此在1988年，喺千葉車站取消咗開車電鈴，並組建咗由女性職員為主導嘅計劃，請來知名嘅音響機器及樂器廠商YAMAHA（山葉公司）製作新嘅出車音樂廣播系統，1989年3月11日開始喺新宿車站同埋澀谷車站導入 。當時使用嘅係係鋼琴同鈴、豎琴等樂器嘅音色，用能夠令人冷靜嘅氣氛嘅音樂做開車音樂。現在這兩個車站已更換其他音樂來使用。
In the late 1970s, the National Railways began to use electronically sounded electric bells (sounds similar to "biro-biro-biro-biro") to prompt driving, but they were not well received. Therefore, in 1988, the company abolished the electric bell at Chiba Station and established a project led by female employees, and hired YAMAHA, a well-known manufacturer of audio equipment and musical instruments, to produce a new music broadcasting system for the train, and on March 11, 1989, it began to be introduced at Shinjuku Station and Shibuya Station. At that time, the sound of musical instruments such as pianos, bells, and harps was used, and the music was used to create a calming atmosphere. Now the two stations have been replaced with other music to use.
