The Hokuriku Shinkansen bullet train almost fully resumed services on its entire route on Friday, for the first time in 13 days.
The line connects Tokyo and Kanazawa, a city on the Sea of Japan coast, via Nagano in central Japan.
Services were partially suspended after Typhoon Hagibis battered central Japan earlier this month. Around one third of the trains were inundated when the storm flooded a depot in Nagano.
The first Shinkansen bound for Tokyo left Kanazawa station at 6 a.m. on Friday.
One female passenger said she is looking forward to visiting Tokyo Disneyland with her grandchild. She said she is happy the Shinkansen service has resumed, as taking a detour would require changing trains, which could be tough for people with small children.
The operators say they will run close to 90 percent of trains for the time being.
