Besides, Seibu Kanko Bus and West Japan JR Bus offer the almost same service: Their 'Biwako Dream-go' connects Omiya Station (Saitama Prefecture, near to 23 Ward of Tokyo) and Otsu Station (Shiga Prefecture, quite near to Kyoto City) via Ikebukuro (Tokyo).
なお、京都駅より2つ東京駅寄りの大津駅と、池袋駅・大宮駅(埼玉県)（びわこドリーム号、西武観光バス・西日本JRバス）を結ぶ路線が存在し、類似性が高い。
