Pork has been a staple food in Japan since the Yayoi period (300 BC-300 AD), and it remains popular today due to its versatility, affordability, and nutritional value. It is also associated with good luck in Japanese culture, and there are many health benefits associated with eating pork. In recent years, sustainable production methods such as free-range farming have been adopted to ensure that pigs are ethically raised while still providing consumers with quality meat products.
