For example, when you travel from Osaka Station to Shin-Osaka to Nagoya (using the Shinkansen line) and to Ogaki Station, a one-way ticket for the entire route can be purchased, without the section between Nagoya and Ogaki counted as duplicated.
例えば大阪駅→新大阪駅→（新幹線）→名古屋→大垣駅と乗車する場合は、名古屋-大垣間を重複とせず全体を1枚の片道乗車券にする事ができる。
