No, a Japan Rail (JR) Pass cannot be reissued if it is lost or stolen in 2026. This is one of the strictest policies in the travel industry; once you have exchanged your "Exchange Order" for the actual physical pass (or even if you lose the voucher itself), the JR Group will not provide a replacement or a refund. If you lose your pass, you must purchase individual tickets for the remainder of your journey or buy a brand-new pass at the full current price. It is a peer-to-peer "must-do" to treat your JR Pass like a stack of cash or your passport. A high-value strategy is to keep a photo of your pass and your receipt, as some comprehensive travel insurance policies may reimburse you for the cost of buying a new one if you can provide proof of the loss and a police report. However, from the perspective of the railway operator, there are no exceptions to the "no reissue" rule, making secure storage of the physical ticket your top priority while exploring Japan.
