The story

On September 12, during the All Japan Corporate Team Championships in athletics, held at Takebishi Stadium Kyoto in Ukyo Ward, Kyoto City, 28 event officials reported symptoms including diarrhea and vomiting and were taken to hospital. According to follow-up reports shared in the thread, 2 were in serious condition, 3 in moderate condition, and 23 in mild condition; athletes, coaches, and other team members who competed were not among those affected, since they had eaten boxed lunches they brought themselves. The thread focused on questions like why only the organizing staff ate heavy boxed lunches such as katsu-toji (pork cutlet simmered in egg), and how the food had been temperature-managed during storage, with posters trading various theories about the lunches’ contents and their relationship to the weather.

Serious condition, huh…
Wonder if there'll be lasting aftereffects

Could end up needing dialysis

>Athletes, coaches, and other team members didn't eat the lunch in question (since they brought their own), so they're not included in the count.

Katsu-toji (pork cutlet simmered in egg) is pretty juicy and hard to let cool down, so it doesn't seem suited for a boxed lunch to begin with

You trying to start something with Trial's 299-yen pork loin cutlet rice bowl?
13AnonymousSep 13, 2026 11:18
Feels like humans have gotten weaker too, huh?
Back in the day people just powered through with germs and all, didn't they?

Re: #13
At street stalls we'd even pick yakisoba up off the ground and eat it
Never had any health problems from it

Re: #13
We're too used to living germ-free
Everyone's gone soft all over

Re: #13
More than that, it's because detection accuracy for mass food-poisoning outbreaks has gotten insanely good
17AnonymousSep 13, 2026 11:19
So the organizers ordered the boxed lunches, and athletes? or invited participants? ate them —
and it was only 28 people?
21AnonymousSep 13, 2026 11:21
Re: #17
Maybe they sensed something was off?
Apparently none of the athletes, managers, or coaches ate it
34AnonymousSep 13, 2026 11:24
Re: #21
Oh really
The teens are probably athletes' family members
Maybe they bundled all the bento reservations into one order

Re: #21
You wouldn't eat something as heavy as katsu-toji right before running
19AnonymousSep 13, 2026 11:20
It's cool out because of the autumn rain front, but it's been raining nonstop
Gotta watch out for food poisoning
23AnonymousSep 13, 2026 11:21
Re: #19
Maybe they made it ahead of time?

>Most of the bacteria that cause food poisoning multiply most actively at 25-37°C. Food-poisoning bacteria also tend to prefer humid environments.



Even if it feels cool, the current temperatures being like this "all day long" is actually the worst case
35AnonymousSep 13, 2026 11:24
Nothing but food poisoning cases lately

Makes you wonder if abnormal weather is changing how bacteria and viruses develop too
54AnonymousSep 13, 2026 11:29
Re: #35
That's your takeaway?
People think "it's cool so we're fine" or cut corners to save money
Isn't it just that management got sloppy?
44AnonymousSep 13, 2026 11:26
If you add natto (fermented soybeans) as a starter, you can completely shut out E. coli, Salmonella, and Staph aureus — the main causes of food poisoning in Japan
It can hold down other bacteria too
96AnonymousSep 13, 2026 11:45
Re: #44
Haha, natto-bacteria muffin. Well, guess you could just eat it alongside a natto roll
111AnonymousSep 13, 2026 11:54
Re: #44
Is there any solid research paper proving natto actually prevents food poisoning?
63AnonymousSep 13, 2026 11:32
The athletes' side is managed as a team, staff included, but the organizing-side staff
get treated like little more than volunteers —
like, just this one bento
and that's it
70AnonymousSep 13, 2026 11:33
Re: #63
So that basically means it's entirely their own responsibility, huh
78AnonymousSep 13, 2026 11:36
Re: #74
They're not selling it outdoors in summer, are they
100AnonymousSep 13, 2026 11:47
Re: #78
Lately in Kanagawa it's actually cooler outside
136AnonymousSep 13, 2026 12:31
Re: #100
Even if it's "lower," once it's above 25°C the risk of food poisoning shoots up like crazy
92AnonymousSep 13, 2026 11:43
Is it the bento shop's fault, or the organizers' fault for leaving the lunches sitting somewhere they shouldn't have?
108AnonymousSep 13, 2026 11:51
Re: #92
If the organizers left them sitting at room temperature for a while after delivery,
that's rough on the bento shop…
105AnonymousSep 13, 2026 11:49
Probably for referees and staff
Though I do wonder why they went with katsu-toji bento
113AnonymousSep 13, 2026 11:56
Re: #105
It's filling, keeps you going longer
147AnonymousSep 13, 2026 12:43
The boxed lunches were probably stored at room temperature
They need to be in a fridge or a room blasted cold with AC — otherwise it's no good
160AnonymousSep 13, 2026 12:57
Re: #147
So you eat it cold, straight up?

Background and key points of this story

The All Japan Corporate Team Championships is a nationwide athletics event hosted by Japan’s corporate/industrial-league athletic federation, and athletes and coaches typically eat meals prepared by their own teams — likely why, in this case too, bringing their own boxed lunches kept them out of harm’s way. Those affected, meanwhile, were the staff supporting the event’s operations, and the boxed lunches provided to them are suspected as the cause. Opinion in the thread split between the view that “people have simply gotten weaker than they used to be” and the view that “this has always happened at some baseline rate — it’s just that testing and reporting have gotten better,” though both remain speculation. Whether food-poisoning cases are actually rising, or whether more cases are simply being caught, can’t be determined from this incident alone — that would require waiting on the health department’s findings on the causative agent and how the food was stored, a nuance easy to miss from the headline alone.
