Nøkkelferier

  • 120 farmers and citizens protested at the PM Office
  • 2020 was the year the US asked for full market access
  • 1 use only is allowed for US fresh potatoes: chip making
  • 25 Sept saw a second protest gathering inside the Diet

Hvorfor det betyr noe

For bønder
Japanese growers should follow the quarantine conditions closely and document pest status, especially potato cyst nematode, to support strict rules.
For prosessorer
Japanese processors should model supply options if access widens beyond chip processing, while planning for strict quarantine controls.
For handelsmenn
US exporters should prepare for detailed plant health requirements; access terms, not the headline decision, will set trade volumes.

60-sekunders sammendrag

Japanese growers are mobilising against a possible opening of their market to fresh potatoes from the United States. Around 120 farmers and supporters demonstrated at the Prime Minister's Office on 24 September, and a farmers' alliance followed with a meeting in the Diet on 25 September. The United States first asked for full access in 2020, and plant health talks are now said to be in their final stage. Today, US fresh potatoes may enter Japan only for chip processing under strict controls. Growers from Hokkaido, Nagasaki and Kanagawa say imports could bring in pests such as potato cyst nematode, undercut prices and upset Hokkaido rotations. For US exporters, a deal would open a large market for table and processing potatoes. For Japanese processors, it could widen raw material options. The final quarantine conditions are not yet public, and no timetable for a decision has been announced.

Japanese potato farmers are campaigning against wider imports of fresh potatoes from the United States. About 120 farmers and citizens held a protest at the Prime Minister’s Office in Tokyo on 24 September, the agricultural cooperative newspaper JAcom reported.

A second gathering took place inside the National Diet on 25 September. It was organised by the National Farmers’ Movement Alliance (Nouminren), the Japan Agricultural News reported.

Hva står på spill

The United States asked Japan in 2020 to fully open its market to US fresh potatoes. Plant health talks between the two countries have now entered their final stage, according to JAcom.

At present, Japan allows US fresh potatoes only for potato chip processing. The imports are kept under strict control.

Speakers at the protest came from Hokkaido, Nagasaki and Kanagawa. They included a grower from Koshimizu in Hokkaido and a cooperative leader from Minami-Shimabara in Nagasaki. Their message was: do not take away the motivation of young farmers.

Pest and rotation concerns

The farmers warned that pests and diseases could enter with imports. Potato cyst nematode already causes problems for Japanese growers, they said. They also said that cheaper imports could break crop rotation systems in Hokkaido. Potatoes are a key crop in rotations with wheat, sugar beet and beans there.

The Diet gathering also raised concerns about post-harvest pesticides and genetically modified potatoes, according to the Japan Agricultural News.

Hokkaido is the main potato region of Japan. Its growers are now in the middle of the harvest.

Hvorfor det betyr noe

A decision by Japan would open one of the largest remaining protected fresh potato markets in Asia. US exporters would gain access for table and processing potatoes beyond chips. Japanese growers fear price pressure and new pest risks. The final plant health conditions will decide how much trade actually follows. Processors in Japan could gain more raw material options, while growers want strict quarantine rules. The outcome will also be watched by other exporters to Asia.

Forebygging og kontroll · Redaksjonell merknad

Potato cyst nematode (Globodera rostochiensis): hva dyrkere kan gjøre

  • Forebygging: use certified, nematode-free seed, grow resistant varieties and keep long rotations without potatoes.
  • Overvåking: sample soil before planting and follow official survey results.
  • Chemical protection in Japan: no effective chemical control; prevention only.
  • Motstandshåndtering: clean soil from machinery between fields and alternate resistant varieties, because resistance genes do not cover every nematode population.
