 The line was opened on March 25, 1991, charging ¥300 for an end-to-end trip, but by this time the ridership projection had been cut to just 12,000 passengers per day.However, between 1991 and 2004 the line only averaged 2,670 passengers per day, amounting to only 6% of the original estimate and 22% of the opening-day projection.The maintenance of the line required some 11.5 billion yen per year, a tenth of Tokadai New Town's budget and, compared to construction costs of 31.3 billion yen, the equivalent of rebuilding the line from scratch every three years.
