Yes, in 2026, it is still highly recommended to preorder your Japan Rail (JR) Pass before arriving in Japan. While you can technically purchase some regional passes at major stations within Japan (often at a higher "in-person" price), the Nationwide JR Pass is most commonly acquired by purchasing an Exchange Order (voucher) from an authorized travel agent or the official JR website abroad. This physical voucher must then be exchanged for the actual pass at a JR office (like at Narita or Haneda airports) upon your arrival. Preordering ensures you lock in the current rates and have all your logistics settled before navigating a foreign rail system. It is wise to order at least two weeks in advance to allow for shipping of the physical voucher, as you cannot simply use a digital confirmation for the nationwide version.
