The chaos caused by Typhoon Faxai, which made landfall on Monday morning as one of the strongest on record to hit the greater Tokyo region, continued to reverberate a day later, exposing the susceptibility of the capital's infrastructure to natural disasters and holding lessons for Japan on transportation and recovery planning in times of emergencies.

As the typhoon approached Sunday evening, East Japan Railways Co. had already notified passengers that all its early morning train services the next day would be suspended until around 8 a.m.

But restoration of service was slower than anticipated and about 2.7 million JR East passengers were affected by train cancellations and delays at the start of the work week. Some services didn't resume until Tuesday morning, while others remained partially suspended even longer.
