An anonymous reader writes: Apparently the conditions for shipping packages via air to the United States have now become so restrictive that the Japanese Post Office has announced that, effective Nov. 17, it will no longer accept any packages weighing over a pound for shipment to the US by any method that involves air transport (including EMS, airmail, and SAL). Except for large corporate mailers, everything over a pound must apparently now come by sea. Asahi Shimbun is reporting that the Japanese equivalents of FedEx and UPS have followed suit. I assume that airmail service remains in effect for the remaining 200 countries across the globe that have not lost their collective minds.
