Avian Flu Spread in Japan Leads to Culling of 5 Million Birds in January
Society Economy Environment Feb 3, 2025
A rapid rise in avian influenza outbreaks in January led to the culling of more than 5 million birds during the month, bringing the total for the season to 8.1 million. Egg prices are slowly rising.
Since the beginning of 2025, avian influenza has been spreading rapidly throughout Japan. The situation has reached a level of serious concern, with 5.4 million chickens and other birds culled in January alone.
According to the Ministry of Agriculture, Forestry, and Fisheries, there have been 43 avian flu outbreaks during this season (FY 2024) as of January 24, second only to FY 2022, which is the highest number ever recorded. However, in terms of the number of birds culled, January 2025 outpaces January 2023, when 4.6 million birds in total were culled.
As of January 22, MAFF had set up local task forces in Chiba, Aichi, and Iwate Prefectures to bolster efforts to counter the spread of infection. Chiba Prefecture had the largest number of egg-laying hens in Japan, at 11.2 million (as of 2024), of which around 2.5 million have been culled (as of January 24)....Comment

Season's 1st Bird Flu Infection in Japan Confirmed in Hokkaido
Sapporo, Oct. 22 (Jiji Press)--The Hokkaido government in northern Japan on Wednesday reported the first case of infection with highly pathogenic avian influenza confirmed at a poultry farm in the country this season.
At the farm in the town of Shiraoi where the case was found, the Hokkaido government started to kill and dispose of some 459,000 laying hens, placing a ban on the transportation of 620,000 hens at four poultry farms within 10 kilometers from the farm in question.
The central government convened a meeting of related ministers in Tokyo on Wednesday morning to ensure close cooperation among government agencies in dealing with the situation.
"This is the sixth consecutive season of an outbreak. Every season, (the disease) goes into full swing from around this time," Chief Cabinet Secretary Minoru Kihara said, emphasizing the need for vigilance.
Ahead of the meeting, agriculture minister Norikazu Suzuki told his ministry's disease control headquarters, "We're in a situation in which further infection cases may happen anywhere in the country."
