The disaster at the Fukushima Daichi plant gave a good portion of East Japan a dusting of radiation, which at the time of the event contaminated several parts of the food supply.
Several hits to my site from search engines have been queries about radiation levels in the food and if it’s safe to eat or not. So I thought I would post about it. I’m no expert, mind you, but I can give you what information I do know.
Any food you find in a supermarket and restaurants will have passed the government’s screening process for radiation and will be within the legal limit.
The legal limit? That doesn’t mean anything to me.
Well, to give you an idea about what it does mean: the Japanese government’s limit for radiation in food is now twenty times stricter than either the E.U. or the U.S.’s regulations.

To give you some perspective, much of the food that would be banned from shelves in Japan because it does not pass radiation screening can be shipped to either and be considered perfectly safe.
There is a food that you may encounter that doesn’t go through government screening though. Eating wild mushrooms can already be dangerous if you don’t know what you’re doing. You run the risk of getting lethally poisoned or a nasty case of diarrhea at best. But in Japan, even the safe ones are not safe. Mushrooms soak in Cesium-134 like a sponge, at a pace 10,000 times that of plants. While domestically grown mushrooms are grown indoors (and passed government screening,) wild mushrooms caught the full dose during the meltdown.
And it’s not just the Fukushima meltdown either. Some wild mushrooms tested in Northern Japan have been found to contain radiation above the legal limit, but tests show a completely different kind of radiation from the meltdown. This radation was found to be from Soviet and Chinese nuclear weapon tests in the 40’s and 60’s, as well as the Chenobyl disaster. The radiation just lingered around for that long, and because mushrooms are radiation magnents, they sucked it up. It was just that no one bothered to test their presence in the food supply until now.

Going into the mountains to pick mushrooms is a pastime in Japan, one that at present poses a health risk if the mushrooms are consumed. Though the vast majority of restaurants are screened, if you go to a tiny little mom and pops in Northeast Japan, they may just use wild mushrooms in their dishes. It’s not that they are evil dealers of misery and death, it’s just that the mushroom issue isn’t wildly known in Japan. They’re just serving you what they think is a local treat.
But now you know better. So be a smart traveler (or resident) when you come, and stay away from those wild mushrooms.
