A small soba counter operates inside Asakusa Underground Street, one of Tokyo’s oldest surviving subterranean shopping arcades. Tucked beneath the streets near Asakusa Station, these compact eateries serve quick bowls of soba and udon to commuters and visitors moving between the metro and the surrounding neighborhood.

Opened in 1955, Asakusa Underground Street is considered the oldest underground shopping street in Japan. Its narrow corridors, low ceilings, and tightly packed storefronts preserve a postwar atmosphere that has largely vanished from Tokyo as major stations modernized. The passageway originally developed as a practical connection point for transit riders, but it evolved into a lively network of bars, snack counters, tobacconists, and small service shops. Today, despite gradual renovation, it remains one of the city’s most atmospheric relics of mid-20th-century urban life—an example of how Tokyo’s underground spaces doubled as both transportation infrastructure and neighborhood social hubs.

Tokyo’s Marunouchi Line is one of Japan’s oldest and busiest subway routes, linking major commercial and governmental districts through a network that dates back to 1954. This view shows the Series 2000 rolling stock, a modernized fleet introduced by Tokyo Metro beginning in 2019 to replace aging Series 02 cars.

The trains feature energy-efficient LED lighting, regenerative braking, and improved accessibility through wider doorways and level boarding. Their bright yellow exterior, trimmed with red and blue stripes, preserves the line’s traditional color while emphasizing the sleek, minimalist design typical of contemporary Japanese transit engineering.

Inside, the cabin layout prioritizes capacity and passenger flow, with longitudinal bench seating covered in patterned orange upholstery and overhead digital route displays in both Japanese and English. The Marunouchi Line operates on a 1,500 V DC overhead catenary and runs entirely underground except for a brief surface section near Nakano-Sakaue, connecting Ikebukuro to Ogikubo over a 24.2-kilometer route that handles hundreds of thousands of passengers daily.

Shiodome Station in Minato Tokyo Japan.

Shimbashi Station serves as a key interchange between Tokyo’s dense urban rail systems, connecting JR East lines with the Yurikamome automated transit route to Odaiba. The elevated Yurikamome track, seen here curving above the city streets, is a fully driverless, rubber-tired train line that opened in 1995 to link Tokyo’s central business districts with its reclaimed waterfront developments.

This structure’s sleek metallic architecture and tiered design reflect Japan’s approach to maximizing space efficiency in high-density transport corridors. The network below includes the JR Yamanote Line, Tokyo Metro Ginza Line, and the Toei Asakusa Line, making Shimbashi one of the most vertically integrated transit hubs in Japan.

Inside a tiled subway passageway, light blue and red accents curve along the walls, leading commuters toward the platform below. The design is distinctly retro, with polished tiles and fluorescent lighting evoking a mid-20th-century aesthetic found in older metro systems. The turn of the corridor reveals a glimpse of signage and station names, grounding the space in the everyday flow of city life.

A stairway leads down to the platform at the Chicago Transit Authority’s Grand Station on the Red Line. The tiled corridor—lined with blue ceramic panels and stainless-steel railings—reflects the late-20th-century design style common to CTA subway renovations, emphasizing functionality and durable materials. The bright fluorescent lighting and tiled curvature guide commuters from street level into the subterranean rail network that connects Chicago’s North Side, Loop, and South Side neighborhoods. The subtle skyline motif on the tiles pays homage to the city’s architectural identity while marking one of the Red Line’s busiest downtown access points.

An illuminated stairway leads up to one of Chicago’s iconic “L” (elevated) train platforms in the Loop at night. The steel structure, marked with the system’s signature riveted beams, is part of the century-old elevated rail network that defines the city’s core transit identity. Below, a “Police Line – Do Not Cross” barricade and the quiet, empty street evoke a rare moment of stillness in an area usually dominated by the hum of trains and late-night traffic. This view highlights the utilitarian geometry and enduring presence of the Chicago Transit Authority’s elevated system, still serving as the backbone of the city’s rapid transit since the late 19th century.

An empty corridor of the Chicago Pedway connects the Randolph/Washington subway station to surrounding office buildings and shopping centers beneath the Loop. The Pedway system, developed beginning in the 1950s, extends for more than 40 city blocks, linking major transit lines with civic and commercial spaces. Its mid-century design—terrazzo floors, tiled walls, and fluorescent lighting—reflects the city’s practical approach to all-weather pedestrian infrastructure, a defining feature of downtown Chicago’s urban core.

The curved platform of a Chicago Transit Authority Blue Line station reveals the utilitarian design of the city’s subway infrastructure, part of the Milwaukee–Dearborn subway opened in 1951. The tunnel’s tiled blue panels and low arched ceiling reflect the postwar engineering era that brought rapid transit beneath the Loop and the West Side, connecting O’Hare International Airport to downtown. Despite its age, this corridor remains a vital artery in Chicago’s daily commuter network, a symbol of mid-century urban mobility still in constant motion beneath the city streets.

Randolph/Washington station sits beneath the heart of downtown Chicago, forming part of the CTA Red Line that runs through the State Street subway. Opened in 1943 as part of the city’s ambitious subway expansion, the station connects directly to the extensive Chicago Pedway system, linking offices, retail centers, and civic buildings underground. Its tiled vault and distinctive 1940s-era design remain largely intact, representing the Art Moderne phase of Chicago’s transit infrastructure.

The Chicago Transit Authority’s Sox–35th station serves the Red Line on the city’s South Side, positioned above the Dan Ryan Expressway near Pershing Road. The station provides direct access to Guaranteed Rate Field, home of the Chicago White Sox, whose name can be seen across the pedestrian bridge in the background. Opened in 1969 as part of the Dan Ryan branch of the Red Line, the elevated structure was designed for efficiency amid highway traffic, symbolizing mid-century Chicago’s integration of mass transit and freeway infrastructure.

The Chicago Transit Authority (CTA) logo is displayed beneath the steel elevated tracks that define the Loop, the city’s central business district. The structure, part of the “L” system first built in the late 19th century, remains one of Chicago’s most enduring symbols of urban mobility. Overhead girders and riveted beams—many still original to the early 1900s—carry trains above streets lined with early skyscrapers and historic facades. The CTA continues to operate one of the largest and oldest public transit networks in the United States, moving more than a million riders daily through Chicago’s interconnected system of rail and bus lines.
