Japan does have sea lions, but their populations have been greatly reduced due to hunting and habitat loss. The Japanese sea lion is now considered extinct, but other species such as the Steller sea lion and California sea lion can still be found in Japanese waters. Efforts are being made to protect sea lions in Japan and around the world through raising awareness and implementing laws to regulate hunting and protect their natural environments. Sea lions face many threats in the wild, including overfishing, pollution, and climate change.
