The Hokuriku Area Pass is best for exploring the Hokuriku area, including Tsuruga, Fukui, Toyama and the Japanese Alps. You get unlimited travel on the JR West network including rapid service train, local trains, buses, non-reserved seats on Bullet Train "HOKURIKU SHINKANSEN between Tsuruga and Kurobe-Unazukionsen and non-reserved seats on Express Trains 'THUNDERBIRD'.
Works well. Saves a ton of money if you are using the Hokuriku Shinkansen regularly. 1 drawback is that the voucher can only be exchanged for a rail pass at specific train stations.
