Im planning on visiting Japan for 12 days, of which the first 4 days in Tokio, and the other 8 traveling towards Osaka. The plan is to visit Kanazawa and Kyoto along the way to Osaka. The full JR pass for 7 days is more expensive than a 7 days regional Osaka - Tokio - Hokuriku Arch Pass. Is it worth it to only buy the regional pass for 7 days, and for the metro/busses in Tokio just separate tickets (or any other alternative for public transport in Tokio) ? Or is it easier and cheaper to buy the 14 day JR Pass, as it makes traveling by public transport in Tokio possible?
