For some time before that era, an announcement indicating how to get on buses of Nihon Kyuko Bus (日本急行バス) (the Japan express bus) from this station was made (in this era, the announcement of 'Kagaku Center-mae (in front of the Science Center)' wasn't made).
さらに以前においては日本急行バスへの乗換を案内していた時期がある（その時期には「科学センター前」の呼称はなし）。
