The series E259, introduced in 2009 as the second generation Narita Express connecting the Tokyo metropolitan area with Narita Airport, began a design renewal in 2023 under the concept of the evolution of the renewed series E259. The redesign adapts to changing usage needs and features a silver-based color scheme on the front and sides of the lead cars to reflect a variety of travel scenes and changing landscapes along the route. From 2024 the series also began operation on the Limited Express Shiosai on the Sobu Main Line, and the airplane emblem on the side of the lead cars was removed.
