Eating fugu in Tokyo: 1 in 10 million chance it kills you

~0.1 micromorts. 1 micromorts. Like taking the train 1,000 km. Measured.

Mortmeter: Worth it. Tokyo fugu masters train for years; you risk more riding the taxi to dinner.

Assuming: One multi-course meal of blowfish prepared by a licensed chef in a Tokyo restaurant.

How we got this: Japanese health records show roughly one fugu death per year nationwide, almost exclusively among amateur fishermen eating their own catch at home. Fatalities in licensed Tokyo restaurants are rarer than one in ten million meals. 1 meal x 0.1 micromorts gives 0.1 micromorts.

What gets you: Tetrodotoxin poisoning from cross-contaminated flesh, Consuming banned organs like liver at illicit speakeasies, Choking on chewy skin.

Cheaper version: Order certified farmed non-toxic fugu to cut chemical risk by 99 percent.

Sources and method: how Mortmeter prices things, and the Atlas of measured risks.
