The Japanese oyster industry is facing a crisis as it grapples with a drastic reduction in oyster populations referred to as a "devastating situation". Experts are currently exploring solutions to preserve this crucial industry. The specific causes of the oyster population decrease remain uncertain; however, environmental changes, overfishing, and diseases are suspect. Immediate steps to restore the oyster population are being prioritized.

Oyster farming is an integral part of Japan's seafood industry, contributing significantly to local economies, particularly in coastal and rural areas. Oysters also play an essential role in marine biodiversity, acting as natural water purifiers. The decline in populations is therefore a matter of national concern, with ongoing discussions about sustainable management and conservation strategies.

In the US and EU, oyster decline has also been a pressing issue in recent years, prompting key environmental and conservation initiatives. Each region has distinct strategies reflective of their specific ecological parameters. The approaches include seeding oysters and establishing marine protected areas. However, finding a global solution that can address the problem across different geographical areas is an ongoing challenge.
