Foreign residents across Japan experienced significant internet disruptions on September 23, 2026, when JCOM, one of the country's largest cable television and internet service providers, suffered a nationwide outage affecting its internet connectivity services. The incident, which began during the morning commute, left countless subscribers without internet access for nearly eleven hours before service was fully restored. According to NHK, the outage began at approximately 9:00 AM on September 23rd, with users suddenly finding themselves unable to access the internet through JCOM's network. The timing proved particularly disruptive for remote workers, online students, and anyone relying on internet connectivity for their daily activities. For expats working from home or managing international communications, the sudden loss of connectivity likely caused significant inconvenience during business hours. JCOM, which operates as one of Japan's major cable television companies and internet service providers, serves millions of households across the country. The company's extensive customer base meant the outage had widespread impact, affecting both urban and suburban areas where JCOM maintains a strong presence. For foreign residents who may not have alternative internet options readily available or who face language barriers when troubleshooting technical issues, such outages can be particularly challenging. The company worked throughout the day to address the technical issues, though specific details about the cause of the outage were not disclosed in official reports. NHK confirmed that JCOM announced the completion of recovery efforts by 8:00 PM on the same day, with all internet connectivity services restored to normal operation. The approximately eleven-hour disruption represented a significant service interruption for a major telecommunications provider in Japan, where reliable internet connectivity is typically taken for granted. For expats living in Japan, this incident serves as a reminder of the importance of having backup connectivity options. While Japan generally maintains excellent internet infrastructure and reliability, even major providers can experience unexpected technical difficulties. Those who depend heavily on internet access for work, particularly remote workers managing international business operations across different time zones, may want to consider maintaining a backup connection through mobile data plans or pocket WiFi devices. The outage also highlights potential communication challenges for non-Japanese speakers during service disruptions. JCOM's customer service and status updates are primarily provided in Japanese, which can make it difficult for foreign residents to obtain timely information about outages and estimated recovery times. Expats affected by such incidents may find it helpful to use translation apps or seek assistance from Japanese-speaking friends or colleagues when contacting service providers during emergencies. While JCOM successfully restored service within the same day, the incident raises questions about redundancy and backup systems for critical internet infrastructure. For businesses and individuals who cannot afford extended periods without connectivity, this outage may prompt reconsideration of internet service arrangements and disaster recovery planning. Moving forward, JCOM customers—including the expat community—should consider documenting JCOM's customer service contact information and familiarizing themselves with the company's status update channels. Having mobile data as a backup option and knowing how to access service status information can help minimize disruption during future outages. As of the evening of September 23rd, JCOM confirmed full service restoration, and normal internet connectivity resumed for all affected customers across the country.
