Chicken is a significant part of the agricultural sector in both the United States and Japan. In the US, chickens were historically raised on family farms or in poultry colonies, with eggs being the primary value proposition and meat being considered a byproduct. Today, the US chicken industry is primarily focused on broiler chickens, raised specifically for their meat, while egg-laying hens are a separate segment. In Japan, there are 38 native chicken breeds, with each area boasting approximately 60 breeds of local chickens. Japanese chicken is used as an ingredient in a variety of dishes, including yakitori, tatsutaage, and steamed chicken over udon noodles. While the US chicken industry has been successful due to efficient structural organization and improved production technologies, Japan's industry experienced rapid expansion after World War II to meet the strong quantitative demands for poultry products with high sanitary standards.

Japan's native breeds are raised under uniform conditions, with free-roaming allowed after 28 days
Chicken farming in Japan involves a rich variety of native breeds, which are raised for long periods under uniform conditions. These chickens are used as ingredients in a wide array of dishes. Japan has 38 native chicken breeds, which were adopted and established over 100 years ago. These chickens are categorised into three main types: local chicken, brand chicken, and broiler chicken. Local chickens are allowed to roam free once they are 28 days old, are bred at a density of no more than 10 chickens per square meter, and are raised for at least 75 days, as outlined by the Japan Agricultural Standards.
Local chicken is known for its moderate chewing consistency, great original taste, and rich flavour. Brand chicken, on the other hand, is produced with a careful selection of breeds and feeds, resulting in meat that is light and tender, with minimal odour. Broiler chicken is distinguished by its exceptional meat-producing capacity, yielding meat that is light in taste and tender in texture.
In comparison to Japan, chicken farming in the USA exhibits certain differences in terms of scale and production methods. According to a 2022 survey by the Ministry of Agriculture, Forestry, and Fishery, Japan has approximately 1,810 layer farms and 137 million layer chickens. In contrast, the US has a larger number of industrial-scale farms and a higher overall chicken population.
The US poultry industry is known for its intensive farming methods, where chickens are often raised in confined spaces to maximise production. While these practices have contributed to efficient meat and egg production, there has been a growing trend towards free-range and organic chicken farming in recent years, driven by consumer preferences for more natural and ethically produced food.
In conclusion, Japan's native chicken breeds are raised under uniform conditions, with free-roaming allowed after 28 days, resulting in a product that is versatile in cooking and valued for its flavour and texture. Chicken farming practices in Japan differ from those in the USA in terms of scale, production methods, and the emphasis on specific chicken breeds and their unique characteristics.

There are 38 native Japanese chicken breeds, compared to the US's focus on broiler chickens
Chicken farming practices differ greatly between Japan and the United States. In Japan, there are 38 native chicken breeds, while the US industry primarily focuses on broiler chickens, which are reared specifically for meat production.
Broiler chickens, originating from junglefowl native to Southeast Asia, have been selectively bred for rapid growth and large pectoral muscles, resulting in a significant departure from their ancestral stock. This intensive production process involves keeping chickens in overcrowded conditions, restricting their natural behaviours such as exercising, foraging, dust-bathing, and perching. The primary objective is to maximise meat yield, with the average American consuming almost 96 pounds of chicken per year in 2021, a significant increase from the 34 pounds consumed annually in 1965.
In contrast, Japan has a diverse range of native chicken breeds, reflecting a different cultural approach to poultry farming. While Japan also has broiler farms, with Kagoshima, Miyazaki, Iwate, Aomori, and Hokkaido being the top five prefectures for broiler production, they also place importance on other aspects of poultry farming, such as egg production. Japan's top ten prefectures for layer chicken numbers include Ibaraki, Chiba, Kagoshima, Hiroshima, Aichi, and Okayama, contributing to the country's overall egg production.
The history of poultry farming in Japan reveals a notable shift in focus. Post-World War II, Japan experienced a sharp increase in the number of layer farms, which peaked in 1955 before decreasing. This shift towards egg production was followed by an expansion in the broiler sector, with the pork sector leading the way in post-war meat production.
The differences between Japan and the US extend beyond the number of native breeds and into the cultural significance and utilisation of chickens. While the US prioritises efficient meat production through broiler chickens, Japan showcases a more diverse approach, valuing both egg production and a variety of native chicken breeds.

Japan's poultry industry expanded post-WWII to meet demand, while the US industry boomed in the 1920s
The poultry industry in Japan and the US have both undergone significant transformations over the years, with Japan's industry expanding post-World War II and the US industry booming in the 1920s.
Japan's Poultry Industry Post-WWII Expansion:
In the aftermath of World War II, Japan's poultry industry underwent a rapid expansion to meet the strong demand for poultry products with high sanitary standards. This growth was facilitated by the introduction of a systematic Western poultry management system, which allowed the industry to become a major agricultural sector efficiently supplying safe and economical meat and eggs to consumers. The number of layer farms in Japan increased sharply after the war, peaking in 1955 at approximately 4.5 million farms, before decreasing. However, the number of layer chickens continued to rise until the 1990s. This expansion was driven by the need to improve productivity and maximize profits, as well as institutional efforts to conserve native chicken breeds.
US Poultry Industry Boom in the 1920s:
The US poultry industry, particularly the broiler industry, experienced significant growth and evolution during the 1920s. Several factors contributed to this boom:
- Vitamin D Supplements: The development of vitamin D supplements in the early 1920s addressed the issue of chicken mortality during winter due to a lack of vitamin D. This enabled farmers to keep their flocks healthy throughout the year.
- Broiler Development: The focus shifted to raising chickens specifically for their meat, known as broilers. Mrs. Wilmer Steele of Delaware is often credited as a pioneer in this regard, as she raised a flock of 500 chicks for meat in 1923 and expanded her business significantly by 1926.
- Technological Advances: Advances in veterinary technology, breeding, and chicken feed improved bird health and productivity. The mild climate and prime location of regions like Delmarva also contributed to the success of the broiler industry.
- Distribution and Slaughter: The Italian mob's involvement in the distribution and slaughter of chickens in New York City, driven by the influx of Jewish immigrants, likely impacted the industry's growth during this period.
- Consumer Demand: Chicken meat became more accessible and affordable, increasing consumer demand. This, coupled with improvements in home refrigeration, allowed chicken to be stored and consumed more easily.
In summary, while Japan's poultry industry experienced a delayed expansion post-WWII to meet sanitary and quantitative demands, the US industry witnessed an earlier boom in the 1920s due to a combination of technological advancements, entrepreneurial efforts, and evolving consumer preferences.

Japanese cuisine values chicken's unique traits, while the US favors processed cuts
Chicken is an indispensable ingredient in Japanese cuisine, with native breeds being raised for long periods under uniform conditions. There are 38 different native chicken breeds in Japan, with local chickens having to have a bloodline that is at least 50% native chicken, be allowed to roam free after 28 days, be bred at a density of no more than 10 chickens per square meter, and be raised for at least 75 days. Local chickens are prized for their unique traits, with each breed offering a distinct taste, richness, and texture. Japanese cuisine, now registered as a UNESCO Intangible Cultural Heritage, thus values the distinct characteristics of each chicken breed.
Chicken is used in a variety of Japanese dishes, including yakitori, tatsutaage, and hot pots. Yakitori, grilled on skewers, is a popular way to enjoy the original taste and richness of chicken. Tatsutaage, a type of fried chicken, is another popular dish known for its crispy texture and refreshing vinegar flavor. Chicken is also commonly used in hot pot dishes, such as chicken vegetable hotpot, which is a simple yet popular dish consisting of chicken, scallion, and egg served over rice.
In contrast, the US has a different approach to chicken production, with a focus on processed cuts and high-volume meat production. The US is a major exporter of chicken meat and eggs to Japan, with chicken meat imports from the US accounting for a significant portion of Japan's chicken consumption. The breeding environment in Japan has been described as inferior to that of the US, with higher density and longer growth periods. Broilers in the US are typically slaughtered at 2 kg after 42 days, while in Japan, they are slaughtered at 3 kg after 50 days.
Additionally, there has been a growing trend in the US and Europe towards improving animal welfare and adopting slower-growing chicken breeds. Over 300 companies in these regions have made the "Better Chicken Commitment", which includes reducing breeding density, providing environmental enrichment, and adopting more humane slaughter methods. This movement has not yet gained traction in Japan, where the connection between animal welfare and the prevention of drug-resistant bacteria is not widely recognized.

Japan has strict food safety laws, and the US prohibits growth hormones in poultry
Japan has strict food safety laws in place to ensure the safety and quality of its food products, including poultry. The country has implemented various regulations and standards under the Food Sanitation Act to maintain sanitary conditions and guarantee the safety of food items such as poultry meat and eggs. Japan's food safety laws cover various aspects, including the processing and production of poultry, the use of additives and agricultural chemicals, and the inspection of slaughterhouses.
In the United States, while growth hormones are prohibited in poultry production, they are approved for use in livestock such as beef cattle and sheep. The use of growth hormones in poultry is not a common practice due to various reasons. Firstly, growth hormones are expensive, and their use in poultry does not promote significant growth, making it economically impractical. Secondly, worldwide health organizations, including those in the US, have established safety standards and approved products for hormone use in livestock, but poultry is not considered in these approvals. Lastly, the use of growth hormones in poultry production is illegal in many countries, including the US, due to health and safety concerns.
The poultry industry in both Japan and the US adheres to stringent regulations and standards to ensure the safety and quality of their products. While growth hormones are not used in poultry production in either country, the US has approved the use of hormones in certain types of livestock to enhance growth and efficiency. However, strict guidelines are in place to ensure the safe use of these hormones and prevent any potential health risks associated with meat consumption.
Japan's poultry industry is highly regulated, with specific standards for layer chickens and broiler chickens. The country has a significant number of layer farms and broiler farms, with the top prefectures for layer chicken numbers being Ibaraki, Chiba, and Kagoshima. Broiler chicken production is also scattered throughout Japan, with Kagoshima, Miyazaki, and Iwate being the top prefectures. The Japanese poultry industry focuses on improving the performance of layer chickens, with specific targets for feed requirements, laying rates, egg weights, and age at 50% lay.
The US poultry industry, on the other hand, operates under different regulations and standards set by the US Department of Agriculture (USDA). While the specific details of their standards are beyond the scope of this response, it is important to note that the USDA plays a crucial role in ensuring the safety and quality of poultry products in the United States. The USDA provides guidelines, conducts inspections, and enforces regulations to maintain the health and welfare of poultry and safeguard consumers.
