There has been a rapid increase in the population of Nutria — large, invasive, semi-aquatic rodents native to South America — in Japan. As their numbers rise, some local restaurants are crafting creative and progressive solutions by including this animal in their menus. This initiative aims to control the growing Nutria population while promoting sustainable eating practices.

In Japan, nutria are considered destructive pests due to their harmful effects on farming and local ecosystems. There's a social interest in managing invasive species and protecting the environment, but humane and sustainable solutions are often sought after due to local values around respect for life and nature. Turning to culinary uses is an innovation that addresses this challenge.

In the US and EU, various approaches are taken to handle invasive species, often involving containment and removal. Innovative culinary solutions are also explored, but not as commonly as more direct interventions. The general aim across regions is to protect native environments while ensuring any measures taken are sustainable and ethical.
