At this time, the World Health Organization (WHO) is not advising general restrictions on travel to Japan.
However, travellers should avoid travel to the areas most affected by the earthquake and tsunami because of disruptions to essential services, such as transport and electric power, and the ongoing disaster relief activities, including the nuclear power plant emergency response and control activities, will make travel difficult and could consume resources needed by relief worker and residents. Moreover, as indicated by the Japanese authorities, travel within the evacuation and exclusion zones surrounding the Fukushima Daiichi nuclear power plant is prohibited.
In general, travellers who do not have essential reasons to travel should give careful consideration to deferring travel to any areas where there has been considerable disruption to the normal infrastructure and where authorities are responding to urgent humanitarian needs.
In addition, International Civil Aviation Organization (ICAO) is of the view that international flight and maritime operations can continue normally into and out of Japan’s major airports and sea ports, excluding those damaged by the tsunami, according to the latest information available from the WHO, the International Atomic Energy Agency, the World Meteorological Organization, the International Maritime Organization and the ICAO.
