‘It Will Be Irreversible’: Farmers Firmly Oppose Lifting Ban on Fresh U.S. Potato Imports as Agriculture Ministry Holds Briefing

The story

Over the proposed lifting of the ban on imports of fresh U.S. potatoes, the Ministry of Agriculture, Forestry and Fisheries held a closed-door briefing for Tokachi-region growers in Obihiro, Japan’s top potato-producing city. The ministry says it has already identified 21 species of pests and diseases that could enter the country, and is now moving into the stage of considering specific measures to prevent their introduction. On 5ch, opinions split: some welcomed the move out of frustration with rising domestic potato prices, while growers voiced concern that if nematode damage spreads, it would become ‘irreversible.’

The Ministry of Agriculture, Forestry and Fisheries, which has been in ongoing talks over lifting the ban on imports of fresh U.S. potatoes, held a briefing for agricultural stakeholders in Obihiro, Japan’s top potato-producing city.

The briefing was held behind closed doors, attended by growers from the Tokachi region and others.

According to the ministry, it explained at the meeting that it has finished identifying 21 species of pests and diseases that pose a risk of entering the country, and will now consider specific measures to prevent their introduction.

Ministry counsellors like that rotate out every few years anyway (lol)
Talk about irresponsible

Do you even know what a 'sanjikan' (ministry counsellor) actually is?
6AnonymousSep 4, 2026 17:06
I mean, domestic potatoes are just too expensive
18AnonymousSep 4, 2026 17:08
Re: #6
Feels like they used to be a lot cheaper and easier to buy

Re: #6
Potatoes used to be the poster child for cheap vegetables, but the past few years they've gotten full of themselves
67AnonymousSep 4, 2026 17:17
Re: #6
People like this will probably just keep complaining even if we can't import food anymore
11AnonymousSep 4, 2026 17:07
You can grow potatoes endlessly with just one planter box
It's basically the real-life 'chestnut bun' trick, isn't it? (a comedy bit about something multiplying endlessly)
25AnonymousSep 4, 2026 17:10
Re: #11
That's exactly the problem
If potatoes can multiply infinitely, so can potato cyst nematodes
14AnonymousSep 4, 2026 17:07
Can't they just irradiate them to kill off the pests?
22AnonymousSep 4, 2026 17:09
Re: #14
Cyst nematodes can't be killed that way
30AnonymousSep 4, 2026 17:11
If the worst happens, it'd be fine as long as the agriculture minister who approved it takes responsibility and commits seppuku
31AnonymousSep 4, 2026 17:11
Pre-processed potatoes should be fine
Why insist on fresh, raw ones?
42AnonymousSep 4, 2026 17:13
Re: #31
Right, that'd be enough
They're already selling tons of it through McDonald's, and now they're pushing fresh ones too
They must just want to destroy Japanese agriculture
33AnonymousSep 4, 2026 17:12
Imported vegetables already get irradiated to kill pests and bacteria via food irradiation, so there's no problem, right?
82AnonymousSep 4, 2026 17:19
Re: #33
Importing goods irradiated with things like cobalt-60 is banned in principle under the Food Sanitation Act. The only exception is for preventing potatoes from sprouting — adding nematode extermination as a new exception would require an advisory-committee review and a revision of the ministerial ordinance at the Health and Agriculture Ministries, and there's no sign of that happening

Domestic potatoes will become a luxury item
The day will come when a three-star restaurant proudly announces, 'And here we have potatoes from Furano'
47AnonymousSep 4, 2026 17:14
Re: #36
Buyers will all start saying 'domestic potatoes are too expensive, we won't purchase them'
37AnonymousSep 4, 2026 17:12
They have no problem using imported fertilizer and feed,
so isn't this just talking out of both sides of their mouth?
38AnonymousSep 4, 2026 17:13
They say it'll be 'irreversible,' but what's the actual situation like inside the U.S.?
66AnonymousSep 4, 2026 17:17
Re: #38
Well, they've got a lot more land
You can't really compare that to land that's never once had the pest get in
49AnonymousSep 4, 2026 17:14
Why bother importing them 'fresh' specifically?
Couldn't they just keep importing them frozen like before?
54AnonymousSep 4, 2026 17:15
Re: #49
The goal is to force purchases in volumes so huge that processing can't keep up
55AnonymousSep 4, 2026 17:15
Wonder if McDonald's fries will get cheaper
64AnonymousSep 4, 2026 17:17
Re: #55
Probably won't change?
They currently import them pre-cut and ready to fry
Maybe they'll switch to importing them fresh and processing/frying them in Japan instead?
97AnonymousSep 4, 2026 17:21
Re: #55
No way that happens
Even now it's 100% frozen from America,
with 20-ton trailers constantly shuttling loads to the processing plants
Japan can't build a processing facility on that scale
112AnonymousSep 4, 2026 17:25
All this nematode talk is just a pretext
In reality they're just scared of losing on price competition
124AnonymousSep 4, 2026 17:27
Re: #112
Well, that's probably true, but…
remember the Irish Potato Famine
pests and disease can wipe out crops in the worst case…
146AnonymousSep 4, 2026 17:31
Re: #112
Don't you know about Ireland?
138AnonymousSep 4, 2026 17:30
Most people just think 'as long as it gets cheaper, anything goes'
149AnonymousSep 4, 2026 17:31
Re: #138
If the pests do get in, it's the Japanese public who'll bear the consequences
152AnonymousSep 4, 2026 17:32
Re: #138
Well, the weak yen has been making everyone poorer…
144AnonymousSep 4, 2026 17:31
'Lowering the food self-sufficiency rate is a crisis for Japan'

It's about time we started questioning that too. If Japanese agriculture isn't forced to compete, the gap with other countries will just keep growing
158AnonymousSep 4, 2026 17:33
Re: #144
There are options, like making consumption tax 0% only for domestic crops, but then it becomes a nightmare if people fake the country of origin
183AnonymousSep 4, 2026 17:36
Re: #144
Talk of self-sufficiency aside, the fertilizer and feed are imported from China, the U.S., and elsewhere anyway
189AnonymousSep 4, 2026 17:37
The potatoes just go to wholesalers, supermarkets, and then households
so saying farming would become impossible because of pests is a nonsensical argument
how exactly is the bug supposed to travel all the way to a farm field?
are farmers going to dump the imported potatoes right in their fields or something?
200AnonymousSep 4, 2026 17:38
Re: #189
Soil moves around
It can even travel on the wind
Come on, get it together
208AnonymousSep 4, 2026 17:39
Re: #189
The same truck that hauls the American potatoes from the port might also make a stop at a Japanese farm afterward, no?

Also, are American growers even bothering to worry about pests when they grow these?

Background and Key Points of This Topic

The proposed lifting of the ban on fresh potato imports is part of ongoing Japan-U.S. negotiations over agricultural market access. Japan has historically refused to allow imports of fresh potatoes for plant-quarantine reasons — namely, to prevent pests and diseases from entering the country. At the same time, as pointed out in the thread, the vast majority of frozen and processed potatoes used for french fries are already sourced from the U.S., so it’s worth keeping in mind the different treatment historically given to fresh versus processed potatoes. It’s also a commonly misunderstood point that food irradiation is permitted under the Food Sanitation Act only as an exception for preventing potatoes from sprouting — applying it for the purpose of exterminating pests, as raised as a concern here, would require a separate process of revising the ministerial ordinance. Opinions in the thread split because complaints about soaring prices produced calls to ‘welcome the lifting of the ban,’ while at the same time there was concern that if nematode damage spreads, it would deal an ‘irreversible’ blow to domestic production — both of which remain speculation at a stage where the details of the briefing itself (the specifics of any prevention measures) have not yet been made public.
