More than 20 katsuo-bushi manufacturers in Ibusuki and Makurazaki halted production for three days starting May 7 [1].
This coordinated shutdown signals a crisis for a region that produces about 70% [1] of Japan's katsuo-bushi, a staple dried fish product. The disruption highlights how geopolitical instability in the Middle East is directly impacting local food production costs in Japan.
The manufacturers, part of a local cooperative, said the soaring price of frozen katsuo was the primary driver for the suspension [1]. These price hikes are attributed to higher fuel costs for fishing vessels, which have risen amid escalating tensions in the Middle East [1].
Moritaka Mifuku, representative of Mifuku Suisan, said the cost of katsuo rose sharply starting in April. He said the current state of the factories is silent because they are resting [1]. While the official coordinated shutdown was scheduled for three days [1], Mifuku said there was a period of nine days of rest [1].
Other industry leaders are calling for government intervention to stabilize the sector. Takayuki Tateyama, representative of Tateyama Shoten, said the industry needs an environment where people can work with peace of mind. He said production would be more sustainable if the government provided compensation or subsidies [1].
The scale of the impact varies by district. While over 20 companies across Ibusuki and Makurazaki were involved [1], reports specifically noted that 11 companies in the Yamakawa district stopped operations [2]. In some facilities, the shutdown displaced about 30 workers who would normally be operating [1]. Some factories had already faced previous disruptions, including one that shut down for two weeks last month [1].
“The region produces about 70% of Japan's katsuo-bushi.”
The shutdown demonstrates the vulnerability of specialized food supply chains to global energy shocks. Because the Kagoshima region dominates the national market for katsuo-bushi, prolonged production halts could lead to scarcity and further price increases for consumers across Japan, turning a regional industrial struggle into a national inflationary issue.
