TOKYO- Up to 70 percent of restrooms at Terminal 2 of Tokyo Haneda Airport (HND) were reported out of service on the morning of November 28, 2025, affecting passengers of All Nippon Airways (NH) and other carriers operating from the terminal.
Japan Airport Terminal said toilets across 144 restrooms were not flushing, and teams were working to restore service. The operator issued notices and directed passengers to use employee facilities while the cause of the failure remained under investigation.
Toilets Clogged at Tokyo Haneda Airport T2
The malfunction was first reported around 5 am by an airport worker. Maintenance teams moved quickly, but the scale of the outage placed pressure on passenger flow during early peak hours.
Terminal 2 handles a high volume of domestic services, so limited restroom access created immediate strain on amenities and support staff.
Posters were placed throughout affected areas to guide passengers. With most toilets offline, crew-use facilities became temporary alternatives. The operator did not provide a timeline for full restoration but confirmed that system diagnostics were underway.
Similar Issue
Terminal 2 has faced past water system irregularities. In November 2019, high levels of salt were detected in the water supply at Haneda Airport. The Ministry of Land, Infrastructure, Transport, and Tourism opened a probe, but the review concluded without identifying a clear cause.
A third-party panel of water and engineering experts examined whether salt contamination entered through foreign matter or system damage.
Tests showed no tampering or facility failure. Water samples matched the supply used at a nearby construction site, but evidence was not strong enough to confirm cross-contamination.
Operational Impact During the 2019 Incident
The problem came to light on November 6, 2019, when staff at an aircraft washing area noticed the water tasted salty. Authorities suspended the water supply to Terminals 1 and 2 while they checked system integrity.
Elevated salt levels were found only in Terminal 2, prompting a full shutdown until tanks and pipes were cleaned.
Restaurants and retail outlets were forced to close during the two-day suspension. Passengers and workers reported inconvenience, and normal operations resumed only after the water tanks were cleared on the afternoon of November 8.
Ongoing Focus on Infrastructure Reliability
These repeated disruptions highlight how essential systems such as water and sanitation directly affect airport continuity.
While the current restroom failure is unrelated to the 2019 salt contamination case, both events underline the need for steady monitoring, rapid diagnostics, and coordinated response teams.
