Airport
Sendai Airport briefly halted for late-night inspection. Airlines added emergency Tohoku flights to absorb Shinkansen demand.
Shinkansen / Rail
Tohoku Shinkansen suspended ~1 month (Fukushima–Sendai section). In-motion derailment necessitated full safety inspection. Demand for alternative transport (flights, long-distance buses) surged.
Accommodation
Increased cancellations in Sendai and Fukushima. Scale was smaller than Kumamoto or Hokkaido events.
Other
2.23 million households lost power (TEPCO/Tohoku Electric service areas). Power restored within a few days for most. Part of Tohoku Expressway under traffic restriction.
