How many countries canceled imports from Japan?

As of my last update in October 2023, several countries, including China, South Korea, and certain regions of the European Union, imposed import bans or restrictions on Japanese food products following the Fukushima nuclear disaster in 2011. The specific number of countries that have canceled imports can vary over time due to changes in regulations and safety assessments. For the most current and detailed information, it's advisable to consult trade or government reports.
