Ambient lighting produces a bright and crisp interior, while the high domed ceiling offers a sense of openness like few other passenger trains. The Skyliner's interior is so comfortable that passengers may not want to disembark after the quick 40-minute ride from Narita Airport to downtown Tokyo.

Doors separating the passenger cabin from the vestibule use glass materials that provide an open and clean look that also ensures bright lighting and a spacious feeling. Floors use Japan's traditional ichimatsu checkered pattern arranged in a wave-like design.

Ergonomically designed seats feature a large pitch of 41.3 inches (105 cm) and width of 18.5 inches (47 cm). Each seat also features its own power outlet that can be used to power personal computers or other devices.

A spacious storage space for luggage is provided between the passenger cabin and vestibule of each car. Security cameras can also be found in each car, ensuring safety and peace of mind.

The Skyliner's aerodynamic wind-inspired design was created by noted designer Kansai Yamamoto.

The Skyliner's livery features the color "wind blue," which is a metallic rendering of Japan's traditional indigo blue color, and a bright white color called "stream white."
