East Japan Railway Company resumed full operations on the Tohoku Shinkansen line today following a powerful earthquake in Aomori Prefecture [1].
The restoration of the high-speed rail link is critical for regional connectivity, as the earthquake disrupted travel between Tokyo and Shin-Aomori, particularly affecting the segment between Morioka and Shin-Aomori stations [1], [2], [3].
JR East suspended services to conduct safety checks after the quake struck on June 25, 2026 [1]. Reports on the intensity of the shaking vary between sources, with some citing a maximum seismic intensity of 6-upper [1] and others reporting 5-upper [2].
Railway officials conducted thorough inspections of the tracks and infrastructure to ensure passenger safety. Once these checks were completed, the company announced the return to normal operations.
"Safety inspections have been completed, and service has resumed on all lines," the JR East public relations department said [2].
There is a discrepancy regarding the exact time service was fully restored. One report indicated that full operations resumed at 10:18 [3], while another source cited the time as 13:56 [1]. Despite these timing differences, the company confirmed that the entire route from Tokyo to Shin-Aomori is now open.
"We have resumed operations on all lines," a JR East spokesperson said [3].
“"Safety inspections have been completed, and service has resumed on all lines,"”
The rapid resumption of service on the Tohoku Shinkansen demonstrates the rigorous safety protocols and infrastructure resilience of Japan's high-speed rail network. By suspending all trains for comprehensive inspections immediately after a high-intensity quake, JR East prioritizes the prevention of derailments over immediate transit, a standard operational procedure in one of the world's most seismically active regions.
