Keisei Electric Railway runs some train operations linking Tokyo and Narita airport, a major air transportation hub located outside the capital in neighboring Chiba Prefecture. The airport currently receives around 40 million passengers a year, with an additional 35 million projected once work on a new runway and the expansion of another is completed by the end of fiscal 2028. Amano, who became president in June, said the expected increases mean "it will be necessary for us to make large investments and improvements to equipment." Implementation of the new services is projected to cost around 40 billion yen ($272.4 million), according to the company. Keisei Skyliner express services are a major transportation link to Narita airport, receiving up to 8.4 million passengers annually. Regarding the decision to introduce new trains, Amano said the firm is "reaching the limit of our ability to increase Skyliner capacity."
