Transport for London unveiled its iconic roundel at Tokyo Metro’s Ueno Station on June 21, 2026, in a ceremony led by TfL Commissioner Andy Lord and London Mayor Sadiq Khan. The permanent installation marks over a century of connection between the two transit systems. Tokyo Metro’s development traces back to Noritsugu Hayakawa’s visit to London more than 100 years ago, when London’s transport network inspired Japan’s metro design.
A Century of Transit Influence
London Underground’s roundel design has become a global symbol of transit safety and service. The roundel’s permanent placement at Ueno Station recognizes London’s role as the origin of Tokyo’s subway system. Andy Lord stated the roundel represents a symbol all Londoners trust. Tokyo Metro President Akihiro Kosaka joined the unveiling ceremony to celebrate the shared history between both transit networks.
Piccadilly Line Disruptions Affect Airport Access
A partial Piccadilly line closure ran from 12:45 a.m. Saturday, June 21, through all day Sunday, affecting central London to Heathrow Airport service. No trains operated between Cockfosters and Uxbridge, removing direct access from King’s Cross, Covent Garden, and Piccadilly Circus. Trains continued between Acton Town and Heathrow, serving all five terminals but requiring passengers to find alternative routes to reach Acton Town first.
RMT Strike Dispute Remains Unresolved
RMT union drivers ended recent strikes over Transport for London’s proposed four-day working week for tube drivers. The June strikes followed earlier action in April and planned May strikes that were called off. TfL and the RMT remain at odds over the compressed work schedule. Union officials stated more industrial action could follow if no agreement is reached, keeping strike risk dormant but not eliminated for summer travel.
Tokyo Metro Marks 100-Year Milestone
Tokyo Metro celebrates its 100th anniversary in 2027, with the roundel unveiling serving as an early tribute. Transport for London expressed pride that London Underground is considered the origin of the Japanese subway system. Both metros serve millions of daily passengers and continue to influence global transit design and operations.
Final Thoughts
London Underground’s roundel now permanently marks Ueno Station, cementing a 100-year partnership between two of the world’s largest transit systems. The gesture underscores London’s lasting influence on global metro design.
