Yes, foreigners can buy a Japan Rail (JR) Pass, provided they are visiting Japan under the "Temporary Visitor" entry status (standard tourism). In 2026, you have two main options: you can purchase the pass online through the official JR-West/East websites before you arrive, or buy an "Exchange Order" from an authorized overseas travel agent. Since the massive price increase in late 2023, the JR Pass is no longer an "automatic" bargain; you now need to travel extensively (e.g., a round trip from Tokyo to Hiroshima and back within 7 days) to make it cost-effective. Foreign residents of Japan (students, workers, or long-term visa holders) are not eligible for the national JR Pass. When you arrive in 2026, you must present your passport with the physical "Temporary Visitor" sticker/stamp at a JR Exchange Office to activate the pass. It is also important to remember that the pass does not cover the "Nozomi" or "Mizuho" trains unless you pay a supplemental "upgrade" fee, which is a common point of confusion for 2026 travelers.
