Two years ago, this blog talked about the Hokuso Line, which has been called the most expensive train in Japan. It runs between Keisei Takasago Station in eastern Tokyo and Inba Nihon Idai Station in northern Chiba Prefecture. Since that article was posted the Sky Access Limited Express opened between Keisei Ueno Station and Narita Airport. In Chiba this train, like the Narita Skyliner, runs on the Hokuso tracks. Consequently, a lot of commuters living in eastern Chiba who use the Hokuso Line to get to work in Tokyo were happy, since the Access adds an extra express train, making it faster to get to their jobs.
In October, the Chiba New Town Railway, which operates the Hokuso Line, started a crackdown campaign against patrons who do what is called orikaeshi josha (“doubling back”). When we first saw the posters for the crackdown campaign in Inzai Makinohara Station, we misunderstood the reason for orikaeshi. Because Inzai Makinohara is not an Access stop, we assumed passengers returning home from Tokyo would take the express to Inba Nihon Idai Station, which is one station further than Makinohara, and then transfer to a local train going in the opposite direction. However, when we checked train schedules it didn’t make any sense. Most times of the day the local train going west from Inba Nihon Idai leaves one minute before any Access train going east arrives there; which means anyone doing orikaeshi would have to wait at least ten minutes for the next local going west.
What we learned is that people don’t do orikaeshi at Inzai Makinohara when they return home, but rather when they leave for work in the morning. To catch the Access, which cuts up to 20 minutes from their commute, passengers can transfer at the next station going west, Chiba New Town Chuo, but by that time all the seats have probably been filled by people who got on at the previous Access station, Inba Nihon Idai. So by “doubling back” to Inba Nihon Idai from Inzai Makinohara they can get a seat on the express.
However, passengers are supposed to pay to do that, and many don’t. Considering that the fare between Inzai and Inba — one station — is ¥290, the operators of the Hokuso Line obviously believe they’re losing a lot of money. Even for commuters with monthly passes, the difference is more than ¥2,000, which explains the crackdown.
