Bitcoin

Japan is a major crypto trading hub (e.g., bitFlyer, Coincheck) and a key holder of US Treasuries. While the disaster is localized, it could trigger short-term yen strength (safe-haven) and a selloff in risk assets like BTC if Japanese investors liquidate to cover losses or meet margin calls. This event also highlights infrastructure vulnerability—any disruption to Japan's power grid or internet could temporarily affect exchange operations, though no such reports yet.

More than 100 aftershocks hit Japan after a deadly earthquake that killed 13 people, with officials warning of potential magnitude 7 aftershocks.
